Monolithic Lining for Steel-Pouring Ladles

The increasing amount of steel being treated outside the furnace and the increase in the quantity of molten metal being transported by rail in ladles are making it necessary to tighten standards on the durability and service life of the ladle linings. Plans developed for a new department at the Chelyabinsk Metallurgical Combine to line steel-pouring ladles will make it possible to replace the traditional brick lining by cast linings composed of refractory concrete. This change will make the lining considerably more durable, decrease accidents, and sharply reduce the amount of manul labor required in the lining operation. This article describes the process and equipment used to make the new monolithic linings.__________Translated from Metallurg, No. 3, pp. 39–40, March, 2005.
