The box-type multi-purpose furnace is a high-tech heat treatment equipment that integrates modern machinery manufacturing, materials, electrification control and other technologies.It can be mainly used for gas carburizing, carbonitriding and heat treatment under controlled atmosphere of workpieces.Vacuum sintered powder alloy high speed steel It can complete direct quenching (direct quenching), intermediate cooling (slow cooling and then reheating and quenching), slow cooling (carburizing and slow cooling), etc. crafting process. Through different configurations, the multi-purpose furnace can be combined with periodic tempering furnaces, cleaning machines, charging trolleys, etc. to form various production lines, which can complete various forms of complete heat treatment processes.Heat treatment process for wide and thick plates The stirring fan in the furnace plays an extremely important role in the uniformity of the atmosphere and temperature of the carburizing furnace. According to its installation method, it can be divided into two types: top fan and side wall fan. The selection of its type should be based on the depth of the carburized layer required by the workpiece, the accuracy of the surface carbon concentration and the density of the workpiece loading.Process Of Preventing Deformation And Cracking Of Mold By Vacuum Heat Treatment Since the temperature in the front chamber is relatively low, cold parts are continuously pushed in, and the heat in the furnace is continuously spread mainly by convection. Therefore, a centrifugal overhead fan is installed to drive the gas in the furnace to flow in a certain direction and pass through the furnace bottom. vacuum-brazing-repair-method-for-cracks
