为了提高钢的生产率,国内外已广泛推广氧气转炉法来加强炼钢过程。但是,在吹氧强化炼钢过程中,目前还不能充分有效地控制钢水加热温度,造成某些炉次钢水温度超过允许范围,导致粘锭、粘焊底盘的率顿增大。国外吨钢模耗一般在13—40公斤,用于锭模和底盘的费用约占钢生产总费用的1.5
In order to improve the productivity of steel, oxygen converter method has been widely promoted at home and abroad to strengthen the steelmaking process. However, during the process of oxygen-enhanced steelmaking, the heating temperature of the molten steel can not be fully and effectively controlled at present, causing the temperature of the molten steel in some of the furnaces to exceed the allowable range, resulting in an increase in the rate of sticking of the ingot and the sticky-welded chassis. Foreign steel die consumption is generally 13-40 kg, for ingot mold and chassis costs account for the total cost of steel production 1.5
