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 .
