The role of the bell furnace The hood furnace is a heat treatment furnace in which the furnace body is a hood, or the furnace bottom does not move, and the furnace hood moves, or the furnace hood does not move and the furnace bottom moves. It is used for batch heat treatment of workpieces.Factors Influencing the Quality of Reaction Sintered Silicon Carbide The traditional bell furnace uses nitrogen-hydrogen mixed gas as the protective medium. Compared with nitrogen, hydrogen has the advantages of good thermal conductivity, low density, low dynamic viscosity and strong reducibility, and gradually replaces the nitrogen-hydrogen mixed gas as the protective gas. At the same time, it puts forward more stringent requirements for the safety control of bell furnaces.CVD/PCD Diamond Tool Brazing First of all, the metal shell of the protective cover and the furnace table are all tested by X-ray to strictly ensure the processing quality of each equipment. Second, at the beginning of
