| Abstract: | The equipment and process of 100 t VD furnace in the big round billet production of Steel Making Plant at Hengsteel were in- troduced. The best flux of argon blow and the best vacuum treatment time of VD refining furnace were obtained by analyzing the effect of the condition for entering into VD furnace, the procedure operation and the vacuum treatment time upon degasification and inclusion re- moval. The practice data showed that the vacuum treatment could achieve the preferable effect of degasification and inclusion removal after improving the process of 100 t VD refining furnace. |
