熔化期
Technology for Producing Free-cutting Sulfur-containing Steel with Cored Wire Injection of Sulfur Addition The experimental results show that the mean recovery efficiency of sulfur was 76%, the treatment time of feeding was 2 minutes or so, and the melting period was shortened.
用喂线法控制增硫生产含硫易切削钢技术处理时间短仅2min左右,大大降低微调增硫工艺时间,电耗和材料消耗大大降低,现场环境改善,污染降低。
