Otherwise , a deoxidation has also to be done close to the first start-up .

否则邻近首次启动时还要进行脱氧。

A thermodynamic modeling for controls of deoxidation and oxide inclusion in molten steel was developed based on these calculations , which was used for thermodynamic calculations for deoxidation , slag-melt equilibration and oxide-melt equilibration in order to control the deoxidation and compositions of oxide inclusion of steel .

以及钢液凝固过程形成的钢中氧化物夹杂分析结果说明,该热力学模拟方法可用于钢包精炼中钢液的脱氧控制和钢中氧化物夹杂控制.
