主要研究单位:武汉钢铁公司十年规划编号:专32—064沸腾钢的产量在各国都占总钢产量的很大比重。但偏析(化学成份不均匀)严重,钢质不良,废品多,1964年开始在武钢炼钢厂采用机械封顶——瓶式模生产沸腾钢,由于抑制了钢液在模内的沸腾促使早期凝固,使钢的偏析减少,以及瓶式模本身的封顶作用,使头部结构改善,切头率
Main research institutes: Wuhan Iron and Steel Company 10 years Planning number: Special 32-064 Boiling steel production in all countries accounted for a large proportion of total steel production. However, segregation (chemical composition is not uniform) serious, poor steel, waste and more, started in 1964 in WISCO steel mills with mechanical capping - bottle mold production of boiling steel, due to inhibition of liquid steel in the mold to promote early solidification , To reduce the segregation of steel, as well as the cap of the bottle mold itself, so that the structure of the head to improve the cutting rate
