Definitions
- the invention relates to the field of the manufacture of semi-finished products such as rolling plates and spinning billets of aluminum alloys by vertical semi-continuous casting.
- the invention relates to a device and a method of direct cooling, double row of jets, ensuring gradual and continuous quenching of the solidifying product, and especially during the start phase of the casting, so as to control and minimize the phenomenon of camber, and allowing hot rolling, or spinning, subsequent without prior sawing of the tapping foot, and without tears or cracks.
- the mold may or may not have, on its working surface, a graphite insert to improve the surface state in steady state.
- the products may be intended for the manufacture of any application in the form of sheets, strips, profiles or forging pieces obtained by extrusion,
- the rolling plates and the spinning billets are typically made by casting in a mold, or mold, vertical and positioned on a casting table over a pit or casting well.
- the mold is rectangular in the case of plates or circular in the case of billets with open ends, except for the lower end closed at the beginning of casting by a false bottom which moves downward thanks to a descender during the pouring of the plate or billet, the upper end being intended for the supply of metal.
- the mold and the false bottom define the cavity in which the metal is poured.
- the false bottom is in its highest position in the mold. As soon as the metal is poured and cooled, typically by means of water, the false bottom is lowered at a predetermined speed. The solidified metal is then extracted by the lower part of the mold and the plate or billet is thus formed.
- This type of molding in which the metal extracted from the mold is directly cooled by the impact of a coolant is known as semi-continuous casting, typically vertical, direct cooling.
- the difficulty lies in the success of the transition from the zero speed of the beginning of formation of the product to the speed of steady state.
- This passage is translated by a deformation of the plate foot, known to those skilled in the art under the name of camber. If it is too pronounced, which occurs when the foot is cooled too violently, the camber can cause what the skilled person calls “pissures”, which can sometimes degenerate into “hanging”, that is, say a jamming of the plate in its mold.
- the camber associated with an unsuitable cooling regime can lead, less catastrophically, to the breakage of the foot or cracks in the foot.
- camber it is known to those skilled in the art that it is necessary to extract less heat from the product during the starting phase of the casting than under steady state conditions.
- different technologies have been developed (pulsation, CO2 injection into the start-up water, use of V-shaped ingot molds and curved false bottoms).
- the most effective techniques are to sufficiently reduce the cooling rate at startup to obtain a stable heating regime, which extracts much less heat than the nucleate boiling regime or the runoff regime.
- the camber speed is an increasing function of the starting speed, which leads to starting the casting at a speed which is generally lower than the steady state casting speed.
- the parameters more important are the filling rate and the casting temperature, a low heat extraction at the start of the start-up phase by using a sufficiently small quantity of water and of adapted thermal efficiency in relation to its quality, the appropriate choice of the starting speed with respect to the initial water flow, finally the choice, at the end of the start-up phase, of the ramp for increasing the casting speed and increasing the flow rate of the cooling water which makes it possible to reach the Speed and cooling parameters adapted to the steady flow of casting, guaranteeing the health of the foot and the minimization of its camber.
- These molds comprise either a horizontal row of holes, or two superimposed rows.
- the present invention proposes to provide a solution to the problem of double camber and quality of the plate foot, without the disadvantages that have been noted for existing solutions, among others and in particular for hard alloys.
- the two rows of holes and said channels are organized with respect to the coolant chamber (2) to be able to simultaneously distribute said liquid with flow rates and substantially equal speeds on the two rows of holes, both during the start phase and during the steady state of casting. This is achieved by using substantially equal diameter holes in the same row and between the two rows.
- the two rows of holes of said cooling device are arranged relative to each other so as to produce jets (4 and 5) which, if they are stretched, form, at any moment of the casting both during startup and during steady state, impacts on the substantially vertical surface containing the working face of the mold, spaced from each other by a distance of between 10 and 40 mm in the vertical direction.
- the diameter of each of said holes in each row is 3 ⁇ 1 mm.
- the spacing between two adjacent holes on the same row is between 10 and 30 mm.
- the invention also relates to a process for implementing said cooling device as previously described for the direct cooling vertical semi-continuous casting of rolling plates or spinning billets (3), and such that the total flow rate of cooling water for all the holes of the two rows, ie the flow leaving the coolant chamber (2), is between 0.3 and 0.8 l / min per linear cm of mold perimeter, at the beginning of the phase transient start of the casting, phase during which the coolant flow rate and the casting speed have not reached their steady state value as described in paragraph "State of the art", then is brought to the desired flow rate for the steady state casting typically 1 l / cm / mi or more.
- said flow of water at the beginning of the transitional phase of start of the casting is between 0.4 and 0.6 l / cm / min.
- the cooling liquid is fed simultaneously to all the holes of the two rows during the starting phase of the casting, so that the camber phenomenon occurs gradually, distributed and continuous, while being minimized by the flow of said liquid.
- the method of implementing said cooling device for the vertical semi-continuous casting of rolling plates (3) uses a casting mold provided with a false flat bottom whose edges are included in a substantially horizontal plane.
- it uses a casting mold provided with a curved false bottom, or a casting mold provided with a false flat bottom with curved rim, so, in both cases, to that the middle of the faces of the product is subjected, during the starting phase of the casting, to the direct cooling by the cooling liquid before the regions of the rolling face furthest from the middle of the face have not yet left the mold.
- said method of implementing said cooling device for the direct cooling vertical semi-continuous casting of rolling plates or spinning billets (3) can use a casting mold provided on its working surface with an insert in graphite (1).
- the figure 2 represents the variation of the surface temperature of the plates of Example 1, measured substantially at half-width at the outlet of the mold, in ° C, as a function of the same flow rate and for the same molds identified in the same manner as previously.
- the figure 3 represents the evolution of the camber, obtained in the case of Example 1, in millimeters, as a function of the initial flow rate of starting the casting, in l / cm linear perimeter of mold and per minute, for three types of molds identical to the previous ones and marked in the same way.
- the figure 4 represents the size of the solidification cells, in ⁇ m, as a function of the distance to the casting skin, in mm, obtained in steady state on a plate of Example 2.
- the symbols in asterisk are relative to the mold with two rows of 32 ° and 22 ° bearing holes and graphite insert, according to the invention, the symbols in a circle with an LHC TM mold of "Wagstaff" with two rows of 45 ° and 22 ° bearing holes.
- the figure 5 represents the typical shapes of strips obtained by hot rolling of a plate foot (only half a width is drawn), left from a cast plate with a mold according to the invention, on the right with an LHC mold TM of "Wagstaff" 45/22 sequentially cooled during the start phase of constitution of the foot.
- the figure 6 is a sectional view of a mold according to the invention, provided with a graphite insert 1 on the working face, its single water chamber in 2, the cast plate 3 being shown at the lower left end of the cup , in uniform gray, with the two beams incident at 32 and 22 ° of coolant respectively 4 and 5.
- the chamber comprises a septum or diaphragm 6, provided with at least one orifice 7 so as to regulate the delivered liquid flow.
- the system of two rows of jets is used.
- the angle of incidence of the jets is an essential parameter of the invention.
- the incidence of the first row of jets watering the product is the most direct. However, the Applicant has found that the more this impact is direct, the less the flow range in which the caulking is stable is extended.
- the first row of jets (4) which waters the product must therefore have an incidence of the order of 32 + 13 -5, and preferably 32 ⁇ 5 °, to allow the establishment of a steady state of heating.
- the second row of jets (5) must therefore have an even lower incidence, and such that the impact distance between the two rows of jets is sufficient for the The heating regime has time to establish itself. Two rows of jets too close are in fact equivalent to a single row of jets. Typically the second row of jets (5) has an incidence of the order of 22 ⁇ 5 ° so that the vertical distance between the impacts of the jets from each of the two rows is between 10 and 40 mm.
- a spatially progressive tempering effect is obtained with moderate cooling, obtained by a first row, then by a second row of jets some twenty millimeters below.
- the spatial progressivity of quenching can be improved in the lateral direction by the use of false curved bottoms or with curved flanges.
- the invention also consists in obtaining a temporally progressive quenching effect, thanks to a gradual and simultaneous increase in the flow of water on the two rows of jets, which makes it possible to avoid the particularly marked phenomenon of double camber inherent in the technology. sequential jets.
- the Applicant has found that the use of rows of 32 ° and 22 ° incidence jets allowed to obtain a stable heating regime for cold water (up to 10 ° C) and for significantly higher linear flow rates ( up to 0.6 l / cm / min) for existing technologies.
- the starting speed obtained is thus extremely robust, guaranteeing a recovery rate close to 100% at casting. It has also been shown during hot rolling of unscored slabs the complete absence of end and edge cracks, thanks to the integrity of the sole and the absence of disturbance of the section related to an exaggerated phenomenon. double camber.
- the Applicant has furthermore found that, during the casting of hard alloys, the steady-state surface slits, observed in the case of a single-row jet mold, are eliminated with a two-row mold of jet jets. 32 ° and 22 ° of incidence.
- the invention will be better understood with the aid of the following examples, which are however not limiting in nature.
- the simultaneous incidence of the cooling water jets on the mold outlet plate was 45 ° and 22 ° with respect to the vertical axis.
- Total flow rates (either for all the holes of the two rows) cooling water, at the start of the casting, 0.55 to 0.60 1 per linear cm of perimeter of mold / min. have been tested. The flow rate was then increased to 1 l / cm / min. in steady state.
- a mold according to the invention with two rows of superposed horizontal holes, all the holes having a diameter of 3.2 mm and being spaced from each other on each row of 12 mm, each of the holes of the lower row being disposed substantially on the perpendicular bisector. the interval between two holes in the upper row.
- the incidences of the cooling water jets, activated simultaneously, on the plate at the outlet of the mold were 32 ° and 22 ° with respect to the vertical axis creating impacts separated vertically by a distance of 18 mm.
- the temperature of the cooling water was 15 ⁇ 2 ° C in all three cases.
- the length of calefaction at the mold outlet was measured by the method known under the name of "ISTM” ("Ingot Surface Temperature Measurement”), which consists of measuring the surface temperature of the plate by pricking a thermocouple of contact on said surface under the impact of the lower jet of cooling, to record the temperature during a descent of 5 mm from the plate, then to repeat the operation throughout the transitional phase start casting.
- ISTM Ingot Surface Temperature Measurement
- the temperature curve as a function of the cast plate length has a bearing from the origin whose relatively abrupt end corresponds to the end of the caulking for a length corresponding to the "heating length" reported on the y-axis. figure 1 depending on the starting linear flow rate.
- the double row of jet molds (activated simultaneously) make it possible to obtain stable stagnation at higher start-up rates than a single-row jet mold. There is no significant influence of the angles of incidence on the cast length affected by the start-up temperature.
- the surface temperature of the plates, substantially mid-width at the outlet of the mold, was also measured by the method known under the name of "ISTM" already mentioned.
- this temperature is much more stable as a function of the water flow rate in the case of the mold with double row of 32 ° and 22 ° incidence jets activated simultaneously, according to the invention (reference 32/22), than in that of the double-row 45 ° and 22 ° impact jets mold activated simultaneously (marked 45/22) which gives rise to hot cracking of the foot at low flow (0.55 l / cm / min.), which reduces the operating range to a very small area, and, in the case of the single-row 30 ° jet mold, which does not allow to obtain stable stagnation for water flows strictly greater than 0.451 / cm / min at this water temperature.
- the mold according to the invention (reference 32/22) can be used for linear flow rates between 0.4 and 0.6 l / cm / min, which is particularly advantageous because this wide range of flow rates makes it possible in particular to compensate for a possible variation in water temperature.
- the mold according to the invention makes it possible to obtain a stable calefaction in the range of optimum product surface temperatures and in a wide range of start-up rates, which other types of mold of the art do not allow. prior.
- camber obtained on the plate was measured and recorded using a "video camera". Its value, the length from which the edge of the plate, is plotted on the y-axis figure 3 , always according to the linear flow of starting and for the same molds as previously.
- camber obtained with the mold according to the invention (reference 32/22) is significantly lower than that obtained with the other molds for start rates lower than 0.6 l / cm / min, which shows the the benefits of progressive quenching achieved with this two-jet watering technology with optimized incidences.
- the size of the solidification cells was measured in the part of the plate corresponding to the steady state of casting by means of the image analysis algorithm p *, at different distances from the casting skin.
- the mold according to the invention makes it possible to obtain a casting structure, at the periphery of the plate, having cell sizes comparable (to within 2 ⁇ m) with those obtained with the LHC TM mold, and a zone thickness. cortical similar, less than 10 mm.
- the metallurgical response obtained is therefore substantially identical to that allowed by the LHC TM mold.
- 1670 mm x 610 mm and 1810 mm x 510 mm format rolling plates made of alloy AA5182, were cast with the same mold configurations as for example 2. The plates were then hot rolled without sawing the feet.
- the typical shapes of the strips obtained are represented in half-width in figure 5 , on the left in the case of the cast plate with a mold according to the invention (cooling with two simultaneous sprays at optimized incidences 32 ° / 22 ° and graphite insert on all the working faces), right with an LHC mold TM from "Wagstaff Inc.” used at startup with sequential cooling at 22 and then 45 °.
- the plate produced by the mold according to the invention has a simple and distributed camber which therefore generates no crack during hot rolling.
