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.Linear Optical Axis Vacuum Quenching 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.Gear Vacuum Carbonitriding It is composed of furnace body, molten pool, sealing cover and liquid riser, and is the basic part of low pressure casting machine.Vacuum Heat Treatment Of Aerospace Aluminum Alloy Materials 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.
