Definitions
- the invention relates to a mold tube for the continuous casting of metals according to the Features in the preamble of claim 1.
- the invention is based on the object To provide mold tube for the continuous casting of metals, which improved Has service life and at which local overheating is avoided.
- the distance of two in the Transitions between adjacent cooling channels smaller than the distance between adjacent ones Cooling channels in the remaining wall sections.
- the heat is dissipated via the cooling channels in the pipe wall changing heat dissipation conditions more.
- the number of recalibrations has no influence on the cooling capacity.
- the cooling ducts can in principle be used in all wall sections on the end faces emerge from the pipe wall. In these areas it is easy to install and secure sealing of a mold tube after recalibration without any problems possible to carry out welds, which are then easy after recalibration reworked to new dimensions.
- cooling channels are provided with a round cross section, the result is further advantage after bending a tube mold to a beam blank format, that the cross sections of many cooling channels are also oval shaped, namely in the sense that the surface areas increase towards the pouring channel, so that a higher heat dissipation can be expected.
- a second solution consists in the features of claim 2 it is also possible to provide cooling channels only in the rounded transitions, while the remaining wall sections and the rounded transitions over one adapted to the outer contour of the tube wall water jacket. at In this solution, the entire pipe wall is not interspersed with cooling channels. Much more are only available in the areas where cooling holes are located Overheating would reduce the service life of the mold tube. By combining a water jacket with the rounded transitions of the Cooling channels introduced into the pipe wall can cause local overheating in the rounded transitions avoided and the service life of the mold tube increased become.
- the cooling channels provided in the transitions can differ from the upper one Face of the pipe wall up to about the middle height range of the pipe wall extend. This is thermally strong for a more intensive heat dissipation in locally claimed wall sections worried (claim 4).
- the cooling ducts and cooling medium outlets connected are provided in the outer contour of the tube wall. These can be particularly advantageous in the middle Height range to be provided on the outer contour of the tube wall (claim 6).
- the front of the Pipe walls introduced closed cooling channels and by overflow channels connected with each other.
- the mold tube is preferably made of copper or a copper alloy.
- FIGS. 1 and 2 denotes a mold tube in beam blank format.
- the mold tube 1 has a double-T-shaped cross section with one over the entire circumference constant thickness D of the tube wall 2.
- the inner contour 3 of the mold tube 1 determines the cross section of the casting strand.
- the cooling channels 4 are introduced into the tube wall 2 by a drilling operation, and before the mold tube 1 is bent. By bending the Then partially deform the cooling channels 4 so that they are larger toward the inner contour 3 Surface areas are formed, whereby the heat dissipation is improved.
- the special inner contour 3 of the mold tube 1 has rounded transitions 6 between a flange area 7 on the one hand and a web area 8 on the other delimiting wall sections 9.
- the distance A from two in the transitions 6 mutually adjacent cooling channels 4 is smaller than the distance B in the rest Wall sections 9.
- cooling channels 4 Enforce mold tubes 1 over their entire length L
- the cooling channels 4 provided in the transitions 6 from the upper end face 5 of the tube wall 2 extend to approximately the middle height range of the tube wall 2.
- These cooling channels 4 can be used to form a cooling circuit at their upper End faces to be connected to one another and via coolant feeds and Coolant discharge in the middle height range of the pipe wall 2 with a Cooling medium can be fed.
- the mold tube 1 can be inserted into an outer contour 10 of the tube wall 2 adapted water jacket be embedded so that the mold tube 1 as a whole is surrounded by a cooling gap through which a cooling medium flows.
- FIG. 3 shows a further embodiment of a in a slightly different perspective Chill tube 11 with an inner contour 12 in beam blank format, also with rounded transitions 13 between a flange portion 14 and on the other hand wall sections 16 delimiting a web area 15
- Exemplary embodiments are cooling bores 4 only in the transition areas 13 available.
- the entire mold tube 11 is in a manner not shown in a water guiding jacket adapted to the outer contour 17 of the tube wall 18 embedded, over which both the other wall sections 16 and with Cooling holes 4 provided transition areas 13 are cooled.
