APPARATUS FOR INTENSIFIED COOLING OF MOLD OF PLANT FOR CONTINUOUS CASTING OF METALS AND ALLOYS Russian patent published in 2003 - IPC

FIELD: metallurgy, possibly plants for semicontinuous and continuous casting of ingots, heat exchangers. SUBSTANCE: mold has working walls with cylindrical cooling ducts. Members that may rotate around their own lengthwise axis by action of moving cooling liquid are inserted inside said ducts. Above mentioned members are in the form of band having rectangular cross section b•Δ, with width b = d and with thickness Δ = (0,1-0,15)d, where d - diameter of round opening of duct. Said band is twisted by preset number of turns necessary for maximum use of cooling capability of cooling fluid. EFFECT: enhanced efficiency and strength of mold due to improved intensity of heat removal from working walls of mold. 3 cl, 3 dwg, 1 tbl, 1 ex
