Development of Casting Process for Ladle Relining

In recent years, operating conditions of steel making process have become very severe to ladle lining refractories. Meeting with such conditions, a development have been made on a new lining process for ladle, CL-L process (Cast Lining of Ladle). This process has been in regular use in large steel ladles. It is a process in which materials added with a small amount of water are charged uniformly through a cone chute and revoluting chute, given fluidity by a former with vibrators and cast to form a uniform monolithic lining. In order to reduce the curing time, this method equips the heat curing equipment. Introducing this method, the ladle life has risen by 3 to 45% and the specific refractory consumption has reduced by 11 to 22% in comparison with the slinger process.
