钢液喂CaSi变质Al2O3夹杂的热力学计算
Thermodynamic Calculation on Modification of Al\-2O\-3 Inclusions by Feeding CaSi Alloy in Liquid Steel
【摘要】 利用热力学数据和天津钢管公司实际生产数据,经热力学计算,得到钢液喂Ca 生成易上浮排除的液态钙、铝复合夹杂,钢中CaAl 比必须满足[ % Al]2/[ % Ca]3 < 1.98×105 。
【Abstract】 Using the thermodynamic data and the practical data of Tianjin Steel Pipe Co, the relation of calcium \| aluminium in steel :[%Al]\+2/[%Ca]\+3 < 1.98x10\+5, that was available to form liquid calcium aluminate inclusion to float up, was obtained by thermodynamic calculation as the molten steel was fed CaSi core wire.
