ER50-6盘条生产实践

Production and Practice of ER50-6 Wire Rod

ER50 - 6焊接用钢盘条系采用氧气顶吹转炉冶炼、炉外处理、小方坯连铸机和高速线材轧机工艺生产。通过采取化学成分控制、炉外处理、全程保护浇注和缓冷等工艺措施 ,使盘条的化学成分稳定、强度低、塑性高 ,拉拔性能和焊接性能优良。经济效益显著。

ER50-6 wire rod for welding are produced by following methods: iron is smelt in top blowing oxygen revolving furnace, treating outside furnace, then continuously cast into small billets and the wire rod is rolled in high speed mill. Taking such measures as chemical compositions controlling, treating outside furnace, protective casting and cooling slowly in the process. The chemical compositions of the rod are uniform, the tensile strength is low, the plasticity is high, drawing and welding properties are fine. Economic profit is remarkable.
