With the data of steel and slag compositions obtained by the oxygen sensor, emission spectrometer and fluorescent X-ray, the behavior of oxygen, phosphorus and manganese at LD end-point were studied. For a quantitative determination a multiple regression analysis was made. The results of a statistical investigation comprising about 100 heats indicated the effects of the molten steel compositions, slag compositions and temperature on the behaviors of oxygen, managnese and phorphorus at LD end-point. |
