Material vacuum crucible induction melting furnace
Material vacuum crucible induction melting furnace product description
Vacuum furnace, that is, in a specific space of the furnace chamber, a vacuum system (carefully assembled by vacuum pumps, vacuum measuring devices, vacuum valves, and other components) is used to discharge some material from the chamber, so that the pressure in the chamber is less than standard atmospheric pressure, and the chamber space achieves a vacuum state. This is a vacuum furnace.
Equipment heated in a vacuum. The tube is connected to a high vacuum pump system sealed with a metal or quartz glass cover. The vacuum in the furnace can reach 133 x (10-2-10-4) Pa. The heating system in the furnace can be directly heated by electrically charged resistance furnace wire (such as tungsten wire) or by high-frequency induction heating. The highest temperature can reach about 3000℃. It is mainly used for ceramic firing, vacuum melting, degassing of electric vacuum parts, annealing, brazing of metal parts and ceramic metal sealing.
The product name | Material vacuum crucible induction melting furnace |
material | Aluminum shell/steel shell/copper |
type | Vacuum quenching furnace, vacuum brazing furnace, vacuum annealing furnace, vacuum magnetizing furnace, vacuum annealing furnace, vacuum sintering furnace, vacuum diffusion welding furnace, vacuum carburizing furnace, etc. |
parts | Vacuum furnace is generally composed of main engine, furnace, electric heating device, sealed furnace shell, vacuum system, power supply system, temperature control system and external conveyor. The sealing furnace shell is welded with carbon steel or stainless steel, and the joint surface of movable parts is sealed with vacuum sealing material. To prevent the shell from deforming and the sealing material from deteriorating when heated, the shell is usually cooled by water or gas. The furnace is housed in a sealed enclosure. Depending on the purpose of the furnace, there are different types of heating elements in the furnace, such as resistors, induction coils, electrodes, and electron guns. The vacuum furnaces for smelting metal contain crucibles and some are equipped with automatic pouring devices and mechanical hands for loading and unloading materials. The vacuum system mainly consists of vacuum pump, vacuum valve and vacuum gauge. |
advantages | 1) completely eliminate the oxidation and decarbonization of the workpiece surface during the heating process, and obtain a clean surface without deterioration layer. This is essential to improve the cutting performance of a tool that only grinds one side during grinding (e.g., twist drill grinding, which exposes the decarburized layer on the groove surface directly to the edge). |
function | Vacuum quenching (tempering, annealing) is a method of obtaining desired properties by heating and cooling materials or parts in a vacuum according to technical rules. |
application | 1. High-pressure and high-flow gas quenching vacuum furnace, 2. Double-chamber high-pressure gas quenching vacuum furnace 3. Double-chamber oil air-cooled vacuum furnace 4. Vacuum aluminum brazing furnace 5. Vacuum high temperature brazing furnace |
