Liquid-cooled ingot mold
View Patent ↗A liquid-cooled ingot mold is provided for the continuous casting of metals. The mold is made up of mold plates or a chill tube made of copper or a copper alloy, which are connected to a support structure by fastening bolts. The mold plates or the chill tube is connected to the support structure without clamping. A working gap exists between the support structure and the mold plates or the chill tube.

3. The ingot mold according to claim 1 , wherein the width (B) of the working gap ( 18 ) is smaller than 0.2 mm.
4. The ingot mold according to claim 1 , wherein the fastening bolts ( 6 , 19 ) are threaded bolts that can be screwed into the mold plates ( 1 ) or the chill tube down to a defined screw-in depth.
5. The ingot mold according to claim 2 , wherein the fastening bolts ( 6 , 19 ) are threaded bolts that can be screwed into the mold plates ( 1 ) or the chill tube down to a defined screw-in depth.
6. The ingot mold according to claim 3 , wherein the fastening bolts ( 6 , 19 ) are threaded bolts that can be screwed into the mold plates ( 1 ) or the chill tube down to a defined screw-in depth.
7. The ingot mold according to claim 4 , wherein the screw-in depth is limited by a clamping sleeve ( 12 ), which is clamped between a bolt head ( 9 ) of the threaded bolts ( 5 ) and the mold plate ( 1 ) or the chill tube.
8. The ingot mold according to claim 5 , wherein the screw-in depth is limited by a clamping sleeve ( 12 ), which is clamped between a bolt head ( 9 ) of the threaded bolts ( 5 ) and the mold plate ( 1 ) or the chill tube.
9. The ingot mold according to claim 6 , wherein the screw-in depth is limited by a clamping sleeve ( 12 ), which is clamped between a bolt head ( 9 ) of the threaded bolts ( 5 ) and the mold plate ( 1 ) or the chill tube.
10. The ingot mold according to claim 7 , wherein the threaded bolt ( 6 ) is screwed into a threaded insert ( 7 ) in the mold plate ( 1 ) or the chill tube, and wherein the clamping sleeve ( 12 ) rests on the threaded insert ( 7 ).
11. The ingot mold according to claim 8 , wherein the threaded bolt ( 6 ) is screwed into a threaded insert ( 7 ) in the mold plate ( 1 ) or the chill tube, and wherein the clamping sleeve ( 12 ) rests on the threaded insert ( 7 ).
12. The ingot mold according to claim 9 , wherein the threaded bolt ( 6 ) is screwed into a threaded insert ( 7 ) in the mold plate ( 1 ) or the chill tube, and wherein the clamping sleeve ( 12 ) rests on the threaded insert ( 7 ).
13. The ingot mold according to claim 1 , wherein the fastening bolts are threaded bolts attached to the mold plate or the chill tube, the threaded bolts being secured by nuts, which can be screwed onto the threaded bolts up to a defined distance with respect to the mold plate/chill tube.
14. The ingot mold according to claim 2 , wherein the fastening bolts are threaded bolts attached to the mold plate or the chill tube, the threaded bolts being secured by nuts, which can be screwed onto the threaded bolts up to a defined distance with respect to the mold plate/chill tube.
15. The ingot mold according to claim 3 , wherein the fastening bolts are threaded bolts attached to the mold plate or the chill tube, the threaded bolts being secured by nuts, which can be screwed onto the threaded bolts up to a defined distance with respect to the mold plate/chill tube.
16. The ingot mold according to claim 13 , wherein the distance is defined by a clamping sleeve clamped between the mold plate/chill tube and the nut.
17. The ingot mold according to claim 13 , wherein the distance is defined by a limiting means on the threaded bolt.
18. The ingot mold according to claim 7 , wherein a spring element ( 10 ) is arranged between the clamping sleeve ( 12 ) and the nut or the bolt head ( 9 ).
19. The ingot mold according to claim 16 , wherein a spring element ( 10 ) is arranged between the clamping sleeve ( 12 ) and the nut or the bolt head ( 9 ).
20. The ingot mold according to claim 18 , wherein the spring element ( 10 ) is a conical spring washer.
