內容簡介Rourkela Steel Plant (RSP) is a major steel plant integrated under Steel Authority of Limited (SAIL). RSP produced 2.17 Mt of crude steel during the year 2011-2012 and is under expansion to enhance its capacity to 4.2 Mt. There are two steel making shops (SMS-I and II), but the major production of RSP comes from two 150 t converters at SMS-II, This shop presently blows 32-36 heats per day by means of 7 steel ladles in operation, with a fleet size of 18 steel ladles. These steel ladles are lined with an MgO-C working lining and facilitate the transfer of liquid steel from the basic oxygen furnace (BOF) to continuous casting machines (CCM). Secondary metallurgical treatment is conducted in a ladle arc furnace (LF) to fine tune the composition and argon (Ar) bubbling is applied for homogenization. The steel ladle lining life plays a major role affecting the quality of the steel produced since lower ladle life means higher inclusion in steel and the cost of production. This paper will elaborate on the performance of ladle life, including lining patterns and operational aspects in SMS-II at RSP.
