A New Design for Corundum Melting Systeme
In this paper is introduced a full mechanically operated new process of corundummelt flowing with individual laddles. Explosion-preventing measures of the laddle are presented. Minia-ture thermal insulating furnace hearth is used. Traditional refractory brick arch is substituted by ther-mal resistant cement ceiling. All this leads to considerable saving of heat conservation cost. Such designis first realized inland and proved to be advantagious in terms of energy saving, electrode material sav-ing as well as labour protection.
