摘要/Abstract

摘要： 在热力学计算的基础上,对中频感应炉中100 kg 0.15C-1.36Mn钢水分别进行加1 kg AlFe、1 kgAlFe+喂0.5 kg钙线和1 kg CaAl₂的终脱氧试验。结果表明,AlFe、AlFe+Ca、CaAl₂终脱氧的脱氧率分别为79.3%、87.2%和85.0%,用CaAl₂终脱氧,炉渣中低熔点相12(CaO)·7(Al₂O₃)和(CaO)·(Al₂O₃)·2(SiO₂)比例明显增多,CaO和Al₂O₃相减少或消失,因此CaAl₂有较强的去除钢中夹杂物的功能。

Abstract: Based on thermodynamics calculation f the end deoxidation of 100 kg 0. 15C-t. 36Mn steel liquid in medium frequency induction furnace is carried out respectively by added 1 kg AlFe, 1 kg AlFe + feeding 0. 5 kg Ca wire, and 1 kg CaAl₂. Results show that deoxidation rate of liquid by AlFe, AlFe + Ca and CaAl₂ is respectively 79. 3% , 87.2% and 85. 0% ； with end oxidation by CaAl₂, the ratio of low melting point phases 12( CaO) . 7(Al₂O₃) and (CaO) • (Al₂O₃) • 2( SiO₂) in slag obviously increases, and the CaO and Al₂O₃ phase in liquid are on the decrease or trace, therefore the CaAl₂ has strong function to remove inclusions in steel.
