摘要：
In order to check the general existence of broadening of slab and the reasons of formation, the broadening of slab was investigated on the basis of several industrial manufactures of continuous casting. The results show that slab broadening commonly exists in the process of continuous casting. The causes of broadening were ruled out of the consideration of the change of mold size or the change of technical parameters. The results reveal that the broadening of slab probably results from the static pressure of molten steel and the force from driving rolls. At the same time, online observations of three grades of steel in the process of continuous casting reveal that the ratio of ultimate broadening of slab ranges from 1. 27% to 3. 00%, and even arrives at 4. 4%.
