采用连铸小方坯轧制冷镦钢盘条生产简述

Production of Cold Heading Wire Rod from Small Continuous Casting Billet

文章对采用连铸小方坯生产的冷镦钢盘条的控冷工艺进行了分析和改进,使之满足连铸小方坯冷镦钢盘条的生产要求。结果表明:连铸小方坯冷镦钢盘条具有理想的F+P体组织和较好的强韧性配合,冷镦检验全部合格,有利于用户冷拔、冷镦加工使用。

The controlled cooling process of cold heading wire rod produced from small continuous casting billet is analysed and improved,which meets the production requirements.The results demonstrate that cold heading wire rod rolled from small continuous casting billet has idea ferrite and pearlite microstructure and better strength and toughness coordination,and all cold heading inspections are up to grade.So it′s good for cold strengthing and cold heading.
