简述了连铸轻压下技术原理,对轻压下压下区间、总压下量、压下速率和压下率等关键工艺与中心偏析的关系进行了研究分析,得到了现场轻压下工艺与中心偏析的一些规律,对现场轻压下试验有一定的帮助和指导作用。 The principle of continuous casting with light pressure is briefly introduced. The relationship between the key process and center segregation, such as the area under the reduction of pressure, the total reduction, the reduction rate and the reduction ratio, is studied and analyzed. Some laws of segregation of technology and center, on the scene of light pressure test has some help and guidance.
