Liquid-cooled mold
View Patent ↗A liquid-cooled mold for a continuous casting of metals, including mold plates made of copper or a copper alloy, which are connected respectively to an adapter plate or a cooling-water tank by clamping bolts. The mold is characterized in that the clamping bolts are fastened to plateau pedestals which project in an island-like manner from the cooling arrangement side of the mold plate, which jut at least partially into a cooling arrangement gap formed between the mold plate and the adapter plate or the cooling-water tank, respectively, and have a streamlined shape adjusted to the flow direction of the cooling arrangement.
1. A liquid-cooled mold for continuous casting of metals, comprising:
mold plates made of one of copper and a copper alloy, which are connected respectively to one of an adapter plate and a cooling-water tank by clamping bolts, wherein the clamping bolts are fastened to plateau pedestals projecting from a cooling arrangement side of the mold plate, which jut at least partially into a cooling arrangement gap formed between the mold plates and one of the adapter plate and the cooling-water tank, and have a streamlined shape adjusted to a flow direction of the cooling arrangement wherein each pedestal is configured in a rhombus shape.
2. The mold according to claim 1 , wherein the clamping bolts engage with threaded inserts fixed in the plateau pedestals.
3. The mold according to claim 1 , wherein the plate is provided with a diffusion barrier in a contact region with a steel melt that is thermally most stressed, in a height range of casting bath level.
4. The mold according to claim 1 , wherein the mold plate is supported via the plateau pedestals on one of the adjoining adapter plate and on the adjoining cooling-water tank.
5. The mold according to claim 1 , wherein the plateau pedestals have a transition region that is rounded towards the mold plate.
6. The mold according to claim 1 , wherein the plateau pedestals are formed as one piece with the mold plate.
7. The mold according to claim 1 , wherein the plateau pedestals are connected integrally to the mold plate.
8. The mold according to claim 1 , wherein the mold plates have a wall thickness which is less than 2.5 times the diameter of the clamping bolts.
9. The mold according to claim 1 , wherein the cooling arrangement gap is connected in a fluid-conducting manner to the cooling arrangement ducts which penetrate the adapter plate.
10. The mold according to claim 1 , wherein a mold plate with a small wall thickness and the adapter plate form a preassembled plate unit connectible to a cooling-water tank, for exchanging with mold plates of the same overall dimensions and connecting measurements as the plate unit.
11. The mold according to claim 1 , wherein the mold plate is made of an aged copper material having a yield strength of more than 300 Mpa.
12. The mold according to claim 1 , wherein a wall thickness of the mold plate measured between the cooling arrangement channel and the casting side is between 5 mm and 25 mm.
13. The mold according to claim 1 , wherein the mold plate has a length of 1.0 through 1.5 m as measured in a casting direction.
14. The mold according to claim 1 , wherein the plateau pedestal is positioned at a mutual distance of approximately 50 mm through 250 mm.
15. The mold according to claim 1 , wherein a sliding aid making easier relative motions is incorporated between the surface of the plateau pedestals and one of an adapter plate and a cooling-water tank.
16. The mold according to claim 15 , wherein the sliding aid is a coating based on polytetrafluoroethylene.
17. The mold according to claim 16 , wherein the sliding aid is a sliding disk.
18. The mold according to claim 1 , wherein the clamping bolts allow a relative displacement of the mold plate with respect to one of the adjoining adapter plate and to the adjoining cooling-water tank.
19. The mold according to claim 1 , wherein the surfaces of the plateau pedestals lying up against one of an adapter plate and against a cooling-water tank lie in planes that are parallel to one another.
20. The mold according to claim 1 , wherein the mold plate are provided with a wear-resistant layer below the casting bath level casting direction, a layer thickness of the wear-resistant layer increasing in the casting direction.
21. The mold according to claim 20 , wherein the layer thickness increases from approximately 0.1 mm to approximately 1 mm.
