Silicon Carbide Roller

silicon carbide roller Performance of silicon carbide rollers         Silicon carbide roller, ceramic rollers, are widely used in tunnel kilns, roller kilns, natural gas kilns, electric furnace wire kilns, silicon carbide kilns and other fields, the heating temperature can reach 1350 ° C, vertical or water safety It is installed on both sides of the furnace cavity, and some furnaces are installed on the top and bottom of the furnace cavity, which can effectively reduce the weight of the kiln car and prolong its service life. The use of silicon carbide roller Scope of application          silicon carbide rollerSanitary ware kiln, nitrogen protection kiln, high-voltage electric porcelain kiln, daily-use ceramic kiln, A-class lightweight foamed ceramics, 1260 ℃ ceramic roller kiln.
