| 钢包和中间包间注流保护 | shrouding between ladle and tundish (In addition to the operation of a ladle metallurgy unit, a high level of steel cleanliness will be achieved through the use of a large capacity tundish to facilitate inclusion removal; shrouding between the ladle and tundish, and tundish and mold; an argon atmosphere in the tundish ; mold powders; and the straight-sided mold. 除了使用钢包冶金设备外，获得钢的高纯净度还将有赖于使用便于清除夹杂物的大容量中间包、钢包和中间包之间及中间包和结晶器之间(注流)的保护、中间包内的氩气氛、结晶器保护渣及直结晶器。) |
