连铸薄板坯表面纵裂纹的产生根源

Based on the casting parameters of Q345B in the CSP Plant of Baotou Steel,the paper analyzes the influences of mould powder,heat flux,casting speed and SEN(submerged nozzle) on the longitudinal crack,and puts forward countermeasures to improve the quality.

文章通过收集大量包钢CSPQ345B钢的生产数据,详细分析了结晶器保护渣、结晶器热流、拉速、浸入式水口等对Q345B钢薄板坯表面纵裂纹产生的影响,并采取相应对策改善质量。

The structure of newly developed longitudinal snapping system and electric control theory have been described,The application effectiveness and the development direction have also been predicted.

详尽介绍一种新开发研制的纵分装置的结构、电气控制、应用效果和发展方向。
