摘要
介绍了含Nb带钢生产过程中边部横向裂纹和纵向裂纹的成因及防止措施,通过降低二冷区冷却强度、保证成品钢中Ti>0.015%、加强脱氧等手段,基本解决了含Nb生产过程中的边部裂纹问题。
The reasons analyse and preventive measures about edge transverse crack and longitudinal crack during contain Nb wide strip steel production are discussed.The problems of the edge crack during contain Nb producting are solved through reducing cooling intensity of the secondary cooling zone,ensuring Ti>0.015% of finished steel and enhancing deoxidation.
