涡鼓型侧吹碱性转炉在我国还处于幼芽阶段,在工业生产大跃进中,全国有许多地区要建立这种炉子,因此质量问题值得重视。上钢三厂去年3~10月用碱性转炉钢轧制过程中产生开裂(压缩比愈大愈严重),并有鳞层、夹杂等疾病,造成大量钢材报废,质量存在一定问题。六厂情况尚属良好。其他唐山、八一的情况我们了解不够,但据悉过去存在一定问题。两年来我们在生产上积累了一些资料,现加以粗略分析,以供参考。
Whirlpool side-blown alkaline converter is still in the bud stage of our country, in the great leap forward in industrial production, there are many parts of the country to establish such a stove, so the quality issues deserve attention. On March 3, last year, the steel plant produced cracking in the process of rolling with alkaline converter steel (the larger the compression ratio, the more serious the compression ratio), and there were scales, inclusions and other diseases, resulting in a large amount of scrapped steel with certain quality problems. Six factory situation is still good. Other Tangshan, Bayi situation we know enough, but it is learned that there are some problems in the past. We have accumulated some information on production in the past two years and we have given a rough analysis for reference.
