The holding furnace is a type of material surface that is ignited and burned at high temperature. After leaving the igniter, it is suddenly exposed to the atmosphere, resulting in rapid cooling of the red-hot material surface. Therefore, in the mineral composition of the surface sinter, the glassiness increases significantly. Strength drop, an instrument of this drawback, is an important part of the low pressure casting furnace.Vacuum Heat Treatment and Nitrocarburizing of Hot Work Die Steel 4Cr5MoSiV1 It is composed of furnace body, molten pool, sealing cover and liquid riser, and is the basic part of low pressure casting machine.Vacuum annealing process of automobile half shaft There are many types of furnaces, such as coke ovens, gas furnaces, resistance furnaces, induction furnaces, etc. The advantages of this type of furnace are simple structure, convenient temperature control and good working conditions. The power of the holding furnace can only make up for the total heat dissipation loss.Differential ring gear vacuum heat treatment The molten pool of the electric reverberatory furnace is large. In order to improve the efficiency, there must be a large heating area, so the molten pool cannot be too deep. In order to facilitate the connection between the mold opening and closing frame and the holding furnace, and to facilitate the repair of the furnace, a mobile frame can be used on the top-casting low-pressure casting machine, or the holding furnace can be designed as a mobile type. However, the heating elements of the mobile holding furnace are easily damaged by vibration and must be maintained.Advantages of vacuum sintering of cemented carbide
