連鑄薄板坯表面縱裂紋的產生根源

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.

文章通過收集大量包鋼CSPQ345B鋼的生產數據,詳細分析了結晶器保護渣、結晶器熱流、拉速、浸入式水口等對Q345B鋼薄板坯表面縱裂紋產生的影響,并采取相應對策改善質量。

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.
