Deskripsi
To improve the effect of LF refining on SPHC steel, thermodynamics software FactSage was used to analyze the physi-cochemical properties of the LF refining slag system, and then the corresponding optimization scheme was verified by industrial verifi-cation. Experimental results show that at the end of LF refining, the total oxygen T[O] in steel decreases from 24×10<sup>-6</sup> to 20×10<sup>-6</sup>, the total removal rate of micro inclusions increases from 56.67% to 71.54%, and the amount of large inclusions decreases to 42.45 mg/10 kg from 85.42 mg/10 kg by the optimization of the LF refining slag system.
