Title:
COATING METHOD FOR REFRACTORY WALL IN ROTARY MELTING FURNACE
Document Type and Number:
Japanese Patent JP3404626
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a coating method for the refractory wall in a rotary melting furnace in which lifetime of the refractory wall can be prolonged by prolonging the lifetime of a coating layer formed on the refractory wall.
SOLUTION: The method for coating the refractory wall in a rotary melting furnace with refractory material while rotating the furnace comprises a step for storing molten slag to be treated in the furnace by interrupting the melting operation temporarily, a step for heating up the stored molten slag to a temperature zone higher than the normal operating temperature, and a step for supplying additive material containing a component having higher melting point than the slag to be treated into the furnace.
