研究了鞍钢股份有限公司板坯连铸机的结晶器电磁制动技术对铸坯皮下夹杂缺陷和冷轧板表面质量的影响。结果表明:电磁制动处理降低了铸坯表层较大尺寸夹杂物的含量,显著改善了冷轧板表面质量,冷轧板表面夹杂缺陷发生率从0.68%降到0.14%。
The effect of mold electromagnetic brake technology on slab inclusions defects and surface quality of cold-rolled steel slabs in Ansteel Co. Ltd slab caster was studied. The results show that electromagnetic brake reduces the content of larger size inclusions on the surface of slab and remarkably improves the surface quality of the cold-rolled steel. The incidence of inclusions on the surface of cold-rolled steel decreases from 0.68% to 0.14%.
