Study on Desulphurization Technology in RH Refining for Electric Steel

Abstract:

To develop the desulphurization technology for electric steel, desulfurizer using for electric steel in RH refining process has been studied. Meanwhile, key technologies such as converter end-point control, modification of ladle slag in secondary refining process, as well as desulphurization technology in RH refining process are studied deeply. Industrial tests show that desulphurization rate in RH refining process is as high as 28% for electric steel, and the ratio which sulfur content below 0.005% is as high as 70%.
