RYL63-50 type atmosphere controlled bell sintering furnace is mainly used to manufacture diamond saw blades and metal bond diamond grinding wheels with the diameter of 400mm or below that requires high accuracy and density, small deformation after sintering. Work pieces of this furnace can be pressed or sintered in a protective atmosphere. Also, two sets of stainless crucibles are equipped in the furnace. Possessing the merits of compact structure, easy loading and unloading of the workpiece, high production efficiency, and small temperature difference in the sintering district, this sintering furnace is the perfect choice for the production of advanced diamond saw blades and metal bond grinding wheels with diameters of 105mm400mm.

Configuration of the Furnace:

Three-phase heating, three-way independent regulations and three-section available for measuring and controlling temperature, advanced intelligent temperature controller, PLC for temperature and pressure are equipped in the furnace. 100 technique curves can be stored in the furnace computer. The pressure, with digital set and display, is converted automatically. Nitrogen or the decomposition of ammonia gas is suggested to be used as the protective gas in those two sets of heat resistant electric driven steel bells which are sealed with sand. Moreover, computers are available for the recording and monitoring of process data.
