Definitions

the invention relates to a continuous casting mold for producing slabs, the has water-cooled narrow and wide side walls, especially for manufacturing of thin slabs, in which case they consist of copper plates Broad side walls on the one hand inside, between one to the two narrow sides each area that runs parallel, a pouring funnel is formed and on the other hand cooling grooves are provided on the outside or on the back.
the thin slabs produced on continuous casting plants serve as pre-strips for production of hot wide strip with final thicknesses between, for example, 1 to 12 mm.
CSP Cosmetic Strip Production
the casting machine with a compensating furnace and a downstream rolling mill is combined in one line (see e.g. DE-Z “steel u. Eisen 108 (1988), No. 3, pages 99 to 109 ").
the funnel-shaped mold with the immersion tube immersed in the pouring funnel the core of the CSP casting process.
the heat dissipation in the bathroom mirror area and the service life the mold is of particular importance here, because in the mold with that there the first solidification of the molten steel supplied through the dip tube significantly influences the surface quality of the thin slab strand becomes.
These criteria apply equally to the production of slabs from the Dimension range 320 to 150 x 3,000 to 800 mm with the help of a then in the As a rule, the plate mold does not require a pouring funnel.
the strand shell growth is essentially from the casting powder, the copper wall thickness between the cooling channel and the working side as well as the flow rate determined in the cooling channels. It has been shown that the main cause for the formation of longitudinal cracks in the strand shell an uneven and / or excessive heat dissipation across the width and height in the upper mold area. The uneven heat dissipation is due to different thicknesses of the lubricating film the strand shell and the copper wall.
the invention has for its object a continuous casting mold of the beginning to create the type mentioned, with which the surface quality of the cast Improve thin slab, especially avoid longitudinal cracks, can at least be minimized.
an advantageous embodiment of the invention in its length limited head end of the wall armor runs parallel to the mold wall, lets mitigate the drop in temperature further. Because this after short rise first, about 20 to 100 mm long section with maximum thickness of the Armor, which can be 3 to 15 mm depending on requirements, is there where the heat dissipation is otherwise too high, and the thicker armouring here thus prevents excessive heat dissipation from the cooling water side is forced.
An embodiment of the invention provides that the armor up to the wall Transition from the pouring funnel to the adjoining one in the continuous casting direction format-determining mold end section decreases. That way achieved that the copper wall thickness before water over the length of the cooling grooves decreases and thus the heat dissipation over the mold height can be influenced in a targeted manner can.
the thickness of the wall armor varies across the mold width and height according to the temperature distribution in the mold.
the different course of the groove geometry in the copper plate favors the desired temperature uniformity across the height and width the mold by a corresponding to the decrease in temperature depending on the Armor designed for casting parameters.
FIG. 1 From a continuous casting mold 1, known as such, of a casting machine for the production of thin slabs, one of the two is complementary in FIG. 1 opposite broad side walls 2 shown schematically These are for Inclusion of a dip tube, not shown, on the inside with a Pouring funnel 3 formed and on the outside with water flowing through it Provide cooling grooves 4 (see also Fig. 3). Which is next to the pouring funnel 3 each edge regions 5 of the two complementary ones extending towards the narrow sides Broad side walls 2 run parallel to one another. In continuous casting direction 6 below of the pouring funnel 3 the mold walls go into the format-determining Pouring cross section 7 (see FIG. 3).
the liquid steel melt introduced into the continuous casting mold 1 up to the bath level 8 cools down over the height of the mold with a very rapid drop in temperature, the to tensions in the increasingly developing in the continuous casting direction 6
Strand shell leads, which cause longitudinal cracks, which in the strand shell primarily up about 150 mm below the bath level 8.
the bathroom mirror 8 is located at a distance of e.g. 20 to 60 mm from the The upper edge of the mold and, based on this, the cooling behavior is characterized the molten steel melt, which forms a so-called in the mold plates, in Fig. 2 leads schematically drawn temperature belly 9, which characterizes it Curve which shows a significant drop in temperature below.
the back 10 of the Broad side walls 2 compared to the previously common, indicated by dashed lines in Fig. 1 Contour has been reinforced by a wall armor 11, which is in Continuous casting direction tapers and with its wedge tip approximately in the transition 12 (see FIG. 3) from the pouring funnel 3 to the subsequent format-determining pouring cross section 7 ends.
the wall armor 11 sets about 20 to 50 mm below the deepest bath level 8, as in Fig. 3 corresponding to the developing Meniscus of the bathroom mirror clarifies and its course across the width of the Adjusted mold.
the head end 11a - the one rising over a short distance Transition is upstream - the wall armor 11 still protrudes into the Area of the temperature belly 9 and extends in this uppermost Section over a length 13 of approximately 20 to 100 mm parallel to the mold wall, before it then changes into the tapering slope
