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 。
According to the thermodynamic data and the actual production data of Tianjin Pipe Company, the molten calcium is mixed with liquid calcium and aluminum in the molten steel to produce calcium, and the content of Ca-Al in the steel must satisfy [% Al] 2 / [% Ca] 3 <1.98 × 105.
