摘要
本文研究了影响20Mn_2链条钢用坯夹杂物的主要来源和控制措施,从转炉终点控制、精炼控制、连铸浇注工艺、耐材优化等方面开展工作,使20Mn_2铸坯有了明显的提高,保证20Mn_2链条钢质量能够满足各链条厂的质量要求。
In this paper, the main sources and control measures of 20Mn2 steel blank inclusions are studied. The working conditions of 20Mn2 slab are obviously improved from the converter end point control, refining control, casting casting process and material resistance optimization. , To ensure that the quality of 20Mn2 chain steel to meet the quality requirements of the chain plant.
