The well-type tempering furnace, utilizing a vacuum system (consisting of a vacuum pump, vacuum measuring equipment, vacuum valves, and other components meticulously assembled and shaped) to expel part of the material within a specific space of the furnace chamber, resulting in a pressure inside the furnace chamber that is lower than standard atmospheric pressure. The chamber space then achieves a vacuum state, defining the well-type tempering furnace. Equipment heated in a vacuum. The pipelines are connected to a high-vacuum pump system within a furnace sealed with a metallic shell or quartz glass shell. The vacuum level within the furnace can reach up to 133 * (10^-2 to 10^-4) Pa. The heating system in the furnace can be directly electrically heated using resistance wire (such as tungsten wire) or high-frequency induction heating. Temperatures can reach approximately 3000°C. It is primarily used for ceramic firing, vacuum treatment, degassing of electric vacuum components, tempering, brazing of metal parts, and ceramic-metal sealing.
Well Annealing Furnace Feature
Vacuum hardening (annealing, tempering) is a process that involves heating and cooling data or parts in a vacuum according to specific rules to achieve the desired functionality.
Vacuum brazing is a welding process where a set of welding parts are heated to a temperature above the melting point of the filler metal but below that of the base material, under vacuum conditions, to achieve wetting and reactivity of the filler metal to the base material's surface, forming a brazed joint (the brazing temperature varies with different data).
Vacuum sintering is a method where metal powder products are heated under vacuum, and adjacent metal powder particles are sintered into parts through adhesion and diffusion.
Vacuum magnetization is primarily used for metal data magnetization processing.
Well-fired furnace structure
The pit-type tempering furnace typically consists of the main unit, furnace chamber, electric heating device, sealed furnace shell, vacuum system, power supply system, temperature control system, and external transport vehicle. The sealed furnace shell is welded using carbon steel or stainless steel, and the mating surfaces of the movable parts are sealed with vacuum-sealing materials. To prevent deformation of the furnace shell after heating and degradation of the sealing materials, the shell is usually cooled by water or air. The furnace chamber is located within the sealed shell. Depending on the furnace's purpose, different types of heating elements are installed inside, such as resistors, inductive coils, electrodes, and electronics. Vacuum furnaces used for metal smelting are equipped with crucibles in the furnace chamber, some with automatic pouring devices and loading/unloading robots. The vacuum system mainly consists of vacuum pumps, vacuum valves, and vacuum gauges.
The Application and Features of the Well Annealing Furnace:
The electric furnace is composed of the furnace body, hearth, bracket, vacuum system, and electrical control system. It is primarily used for vacuum tempering and reheat of metal parts, ensuring that the parts are not oxidized during the processing. The furnace's heating temperature can reach approximately 750°C, and the suitable vacuum level can reach up to 133 Pa. It can remove volatile substances from products (such as oil, water, or other gases), making it an ideal equipment for improving the quality of metal parts and ensuring product performance. The purpose of the well-type tempering furnace: high-speed steel tools, molds, woodworking tools, silicon steel plates, motor stators, rotors, metal blade steam heat treatment. After treatment, they exhibit excellent wear resistance, rust resistance, corrosion resistance, and insulation properties.
