摘要 在分析ML08Al冷镦钢对钢中夹杂要求的基础上,设计了LF精炼终渣的组成范围,并确定了相应的现场造渣制度.生产实践表明,精炼渣化渣情况良好,脱硫率较高,能满足生产要求.对连铸方坯洁净度研究表明,在目前生产工艺条件下,铸坯T[O]<20×10-6,大样电解夹杂总量<10mg/10kg钢.同时对钙处理进行了相关热力学探讨,确定了钢中[Ca]的控制范围. Based on analysis of the inclusion restriction in ML08Al steel, the component range of final refining slag was designed and the slag forming system was determined. The productive practice shows that the slag melting condition of refining slag is better and the desulphurizing ratio is relatively high, which can satisfy the requirements of steel grade. The research on cleanliness of billet continuous casting shows that, under the current condition, the T[O] content is less than 20×10?6, the inclusion amount of electrolytic is less than 10 mg/10 kg steel. The thermodynamics of Ca treatment was also discussed.
