摘要
对球铁芯复合轧辊冒口端辊颈缩松原因进行了分析。介绍几种控制辊颈缩松的措施及效果,包括:提高冒口铁液温度;增加二次冒口,用高碳铁液补注冒口,提高冒口液位并吹氧;提高砂箱刚度和型壁冷却能力;减少吃砂量。
The shrinkage reason of roller neck connecting with riser was analyzed. Some shrinkage controlling measures and their effects were introduced, including: increasing liquid iron temperature of the riser; adding secondary riser; re-pouring the riser with high CE iron liquid; controlling iron level and injecting oxygen; increasing rigidity and cooling capacity of the moulding box; reducing sand layer thickness.
