摘要： PURPOSE:To form strong solid surface layers in a top part quickly by inserting a steel plate under the surface of molten steel upon ending of continuous casting and holding the steel plate until it is fixed by the solidified steel. CONSTITUTION:An immersion nozzle is removed upon ending of continuous casting, and the operator holds the handle 5 of a steel plate and inserts the plate into a casting mold from the short side 6 thereon so as to sink the plate slightly into molten steel 7 from the upper part 9 of meniscus. The steel plate is held level until the circumference of the body 1 thereof is restrained by the solidified shell in the casting mold. The molten steel overflows from the bottom surface of the steel plate onto the steel plate in this stage and melts the weld zone between the handle 5 and the body 1; therefore, the handle 5 is removable. Then, the solidified shell 8 formed upon cooling of the steel plate is formed around the steel plate, and the strong solid surface layers 1, 8 which prevent the outflow and bleeding of the molten steel are formed by the two.
摘要翻译：目的：通过在连续铸造结束时将钢板插入钢水表面，并将钢板固定在固化钢板上之前，通过将钢板插入钢水表面，快速地在顶部形成强固体表面层。构成：在连续铸造结束时，浸没式喷嘴被拆除，操作人员握住钢板的手柄5，并将板从其上的短边6插入铸模中，以将板轻轻地从钢板7中沉入钢水半月板的上部9。钢板保持水平，直到其主体1的圆周被铸模中的凝固壳约束。在该阶段，钢水从钢板的底面向钢板上溢出，熔化手柄5与主体1之间的焊接区域; 因此，手柄5是可拆卸的。然后，在钢板的周围形成冷却钢板时形成的凝固壳8，通过两者形成防止钢水流出和渗出的强固体表面层8。
