摘要: 在分析ML08Al冷鐓鋼對鋼中夾雜要求的基礎上,設計了LF精煉終渣的組成范圍,并確定了相應的現場造渣制度.生產實踐表明,精煉渣化渣情況良好,脫硫率較高,能滿足生產要求.對連鑄方坯潔凈度研究表明,在目前生產工藝條件下,鑄坯T[O]<20×10^-6,大樣電解夾雜總量<10mg/10kg鋼.同時對鈣處理進行了相關熱力學探討,確定了鋼中[Ca]的控制范圍.

Abstract: 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.
