LIQUID-COOLED MOLD Russian patent published in 2004 - IPC

FIELD: metallurgy, namely processes and equipment for continuous casting of steel.

SUBSTANCE: liquid cooled mold for continuous casting of steel ingots includes shape forming body of high heat conductance material such as copper or its alloy. Such body of mold mainly includes two mutually opposite wide lateral walls and narrow walls limiting width of ingot. Wide lateral walls form funnel-type casting zone. In order to prevent cracking in zones with increased heat and mechanical loads, particularly in zone of metal heel of bath there is cooling zone with increased specific heat flux. Said cooling zone extends at least along 20% of meniscus length of wide lateral wall. Shaping cavity has at side of casting steel at least one bulge that decreases in direction of casting.

EFFECT: elimination of cracking in zones with increased heat and mechanical loads.
