前言我厂是以采用瓶式模生产沸腾钢为主的钢厂。目前沸腾钢轧后结疤废品仅次于气泡,居第二位。今年上半年的总结疤退料5,080吨,占轧后废的25%;其中沸腾钢结疤4,342,吨(结疤率0.69%),占总结疤的85.5%可见沸腾钢结疤已成为我厂第二号质量问题,必须加以研究解决。 Preface Our factory is based on the use of bottle-shaped mold steel production-based steel mills. At present, after boiling steel rolling scarred scrap second only to bubbles, ranking second place. In the first half of this year, a total of 5,080 tons of scar were rejected, accounting for 25% of the total amount after the rolling. Among them, 4,342 tons of boiling steel scar (0.69% of scarring rate) accounted for 85.5% of total scarring. The second quality problem must be studied and solved.
