STUDY ON CONTINUOUS CASTING PROCESS OF LOW-ALLOY STEEL
-
摘要: 研究了连铸低合金钢的拉速、二冷配水,结晶器保护渣,结晶器喂稀土丝等工艺,解决了低合金钢连铸工艺容易产生铸坯表面裂纹,水口堵塞等问题,为攀钢135 0板坯连铸机生产低合金钢奠定基础。Abstract: The problems, such as easily appearing slab surface crack and nozzle clogging in the continuous casting process of low-alloy steel, were solved through the studying on continuous casting velocity, second cooling model, mold powder, wire feeding operation of RE line and so on. The above-mentioned research is the basis for PZH Steel's 1350 slab caster to produce low-alloy steel?
