The heating device of the mesh belt furnace used to be a stainless steel liner, but now a point heat radiation tube is generally used. The heat radiation tube is composed of a tube core and a tube jacket; Vacuum sintering of transparent ceramics the tube core has a cage type, a vertical winding type, and a resistance wire wrapping type. The material has the characteristics of high temperature oxidation resistance, good carburization resistance and long service life.Silicon Carbide Reaction Sintering Process The tube jacket is generally made of high temperature resistant and oxidation resistant materials. Different specifications of radiant tubes have different specifications, generally the effective length is 600mm-2400mm; PRECISION CNC SURFACE GRINDING MACHINE the single power is 1.5-40KW; the single voltage is 12-220V; the outer diameter of the tube sleeve is 60-280mm (for mesh belt furnace). In addition, some mesh belt furnaces use heat-resistant steel as heating elements.FX27-60 HIGH PRECISION TRADITIONAL CYLINDRICAL GRINDER
