我们伟大领袖毛主席教导我们说:“中国应当对于人类有较大的贡献”。按着毛主席的伟大教导,我们探讨了低炭沸腾钢板产生分层缺陷的原因,也就是钢中夹杂物来源的问题。低炭沸腾钢板最严重的缺陷是分层。据不完全统计,鞍钢在1963～1964年间由于分层缺陷所造成的废品达13.485吨,近年来开展了许多以减少分层为目的的试验研究,其中较为有效的是瓶口钢锭模的使用。生产统计证明,敞口锭的分层废品率为14.9%,而瓶
Chairman Mao, our great leader, taught us that “China should make a greater contribution to mankind.” According to Chairman Mao’s great teaching, we explored the reasons for the stratification of low-carbon steel plate, that is, the source of inclusions in steel. The most serious drawback of low carbon steel plate is stratified. According to incomplete statistics, Anshan Iron and Steel Company in the period of 1963 to 1964 due to delamination defects caused by the waste of up to 13.485 tons, in recent years to carry out many studies to reduce stratification for the purpose of which is more effective is the use of bottle mouth ingot mold. Production statistics show that open decontamination layered rejection rate of 14.9%, while the bottle
