огнеупорные бетоны! Корунда и муллита преломляют

refractory castables! Corundum and mullite refractory castables and compound preformed refractory units High-speed heat flow erosion and ball dynamic conditions of wearing and tearing, and the low-melting materials under high temperature erosion, infiltration of rotary kiln body, the demanding is rigour for the refractory materials. These materials have high temperature strength, wear resistance, corrosion resistance, long-life time and other excellent properties. It can meet the working conditions of the ball group – rotary kiln.
