Abstract

DC60 (23/12/57) Copper die-casting tubes for continuous casting of metal with polygonal internal and external cross-sections. And approximate wall thickness Which is 8% to 10% of the distance between internal surfaces Which are located opposite to each other at the outlet of the pipe, the inner surfaces are laid indirectly Under the influence of the heat dissipation of the substance The cooling medium that can be fed to the pipe wall from the outside at the height of the Molten metal basin Wall thickness was reduced to 10% to 40%. Copper molded tubes (1b) for continuous casting of metal have a polygonal internal and external cross-section and approximate wall thickness, which It is an amount of 8% to 10% of the distance between the internal surfaces. They are located opposite, in front of each other, at the outlet of the pipe (4a). The inner surface is laid indirectly under the influence of heat dissipation. Of the refrigerant that can The pipe wall was fed from the outside at the height (14) of the level of the molten metal bath, the wall thickness was reduced to 10% to 40% of the estimated wall thickness across the entire perimeter.
