摘要
通过分析中薄板连铸机结晶器铜板的磨损情况和连铸坯的缺陷情况,认为结晶器的大面锥度不对称、窄边支撑能力不足和镀层结构不合理是制约结晶器寿命提高的主要因素。制定了垫片调整大面锥度、增加窄边足辊和优化镀层结构等措施,结晶器平均寿命从144炉/次提高到306炉/次,最高使用寿命为517炉。
According to the analysis of the mould copper plate wear and the slab＇s defects for the medium-thin slab caster, the author has found the factors that affect the increase of the mould lifespan, These factors include the wide face taper＇s asyrmnetry of the mould, the lack of the narrow face supporting and the illogical coating structure of the mould, Through taking some countermeasures such as the shimming adjustment of the wide face taper, the new design of narrow face foot roller and the change of the coating structure, the average life of the mould was increased to 306 heats per once from 144 heats per once and the highest service life was 517 heats.
