摘要
热轧窄带65Mn是莱钢开发用作锯片原料的产品,针对65Mn生产中出现的铸坯中心疏松、内裂、漏钢及夹杂物、硬度高的问题进行了分析,认为存在过热度高,原材物料及工艺控制不当等不良因素,通过对冶金原料、耐材、终点成分、精炼及连铸工艺等方面进行调整,逐步控制了质量缺陷,达到生产要求。
Hot rolled ribbon steel for 65Mn is a newly developed steel type which is used in material of saw in Lai steel.Some issues in the production of 65Mn were analyzed,which include slab center porosity,crack,breakout,inclusion and high rigidity.The result shows that there are some factors influencing the production such as superheat,improper control of raw material and technology.The quality defects were controlled to achieve the production requirement by adjusting metallurgical raw material,refractory,end component,refining and continuous casting technology.
