METHOD OF CONTINUOUS CASTING OF SLABS Russian patent published in 1995 - IPC

FIELD: foundry engineering. SUBSTANCE: liquid metal feeds into crystallizer with a varying speed and solid-liquid ingot is reduced in a secondary cooling zone with the help of rollers. Ingot reducing distance is determined by the function L=(0,08-0,40)V/l, where L is distance from the lower side of crystallizer up to the starting point of ingot reducing, m; V is ingot drawing speed, m/min; l is ingot length in crystallizer, m; (0,08-0,40) is empirical coefficient considering thermal properties of casting metal, i.e. metal temperature, viscosity, heat capacity, admissible stress under high temperatures, chemical composition, l/min. EFFECT: enhanced efficiency. 1 dwg, 1 tbl
