【Abstract】 The experiment which simulates continuous casting of steel was done on a casting experimental apparatus with flow control mold, the Pb Sn Bi alloy and silicon oil were adopted to simulate the molten steel and power, respectively. The results show that the flow control mold is able to control the meniscus fluctuation and the flow pattern in the zone of submerged entry nozzle, which is good to the internal and surface qualities of the slab.更多还原
