METHOD OF CONTINUOUS CASTING Russian patent published in 1995 - IPC

Abstract RU 2038185 C1

FIELD: foundry engineering. SUBSTANCE: metal feeds into crystallizer, ingot is drawn out of crystallizer, slag mixture is fed to a metal meniscus in crystallizer, crystallizer is set in reciprocated motion, crystallizer walls are cooled with running water, ingot is supported and guided in secondary cooling zone with the help of split rollers with auxiliary bearings, ingot surface is cooled with a cooler, sprayed from injectors, water discharge used for crystallizer cooling is adjusted and rollers displacement regarding processing axle is measured. Auxiliary bearing displacement is detected in process of continuous casting. When displacement exceeds point of 0,0005-0,006 of ingot thickness reciprocated motion frequency of crystallizer increases for 10-50 percent of working value. Reciprocated motion frequency reduces when further displacement of auxiliary bearing reduces up to 0,0001-0,002 of ingot thickness. Under given conditions bearing displacement is measured at the distance equal to 0,5-5,0 of ingot thickness from the bottom side of crystallizer. EFFECT: enhanced quality. 1 tbl
