摘要

METHOD FOR CONTROLLING INTERNAL PRESSURE IN MOLD CAVITY IN MOVING-MOLD TYPE CONTINUOUS CASTING MACHINE In moving-mold type or dual-belt type continuous casting machines, the molten metal static pressure in the mold cavity is detected and the quantity of the molten metal poured through the tundish nozzle into the mold cavity is controlled such that the static pressure in the mold cavity is maintained at a predetermined range in which penetration of the molten metal into the gap between the tundish nozzle and the mold assembly can be avoided.
