The results showed that the thickness of initial solidified shell in two-stage mold was thinner about 0.4 mm than that in conventional mold. The temperature of strand surface increased about 2.5 K and the initial solidified point descended about 9 mm in two-stage mold. They would bring the effect of hot-top mold, which was good to improve the surface quality of strand. The thickness of initial solidified shell descended with the length of top half of mold increasing, as resulting in serious scouring of molten metal on the connection of two-stage mold. The length of top half of mold 120 mm was thought as the better parameter to meet the requirement of continuous casting industrial production. In the present research condition, the heat-resisting strength on two-stage mold wall was satisfied with the requirement of safe production.
