METHOD OF CONTROLLING COOLED WALL WITH OPENINGS Russian patent published in 1995 - IPC

FIELD: transport mechanical engineering. SUBSTANCE: wall 1 to be controlled is provided with openings 3 and connected with shell 3 which define passage 4 together with wall 1 and collector 5 connected with openings 2. Wall 1 is then set in bath 6 filled with melt 7 of a crystallizable metal. Gas, having a temperature less than the temperature of crystallization of the melt, is then fed to passage 4 and simultaneously cooling air of the gas temperature is injected to main gas flow through collector 5 and openings 2. The blowing is carried out up to forming metal scum 8 on wall 1. The blowing is then repeated, the temperature of the injected cooling gas being lesser than the gas temperature. The cooling efficiency of wall 1 can be judged by relative temperature of the wall defined by the relationship presented in the invention description. EFFECT: improved accuracy of controlling. 1 dwg
