How to maintain the vacuum sintering furnace

A vacuum sintering furnace is a device that reduces the shape of an object or substance by heating it at high temperatures.It could reduce objects in space, grain boundary gradually gathered, solid particles gradually connection, so as to realize the density increases, the decrease of the object of the polycrystalline sintered body equipment.
How should vacuum sintering furnace be maintained in peacetime?
1, the import and export of the equipment, the driving bunker must ensure the clean and clean.
The cleaning of the discharge mouth will clean up the organic matter.
The main body of the chamber is to see if the pores are blocked.
If there is organic material on the lamp tube, it can be cleaned with non-woven or alcohol cotton.
The diagonal mesh band will be able to be softened and then scooped out when it is delivered 120.
The belt of the thimble can be polished with sandpaper to prevent damage to the battery.

What are the factors affecting the quality of vacuum sintering furnace production?

Vacuum sintering furnace production quality besides internal factors and there are many external factors, we take a look at what are the factors that affect the quality of vacuum furnace production.
Structure, temperature control of vacuum sintering furnace, heating process and furnace atmosphere etc., will directly affect the quality of the products after vacuum furnace production. Within the forging heating furnace, raise the temperature of metal, can reduce the melting resistance, but the temperature is too high will cause grain oxide or burnt, seriously affect the quality of the product in a vacuum furnace. In the process of heat treatment, if the steel is heated to above the critical temperature of a point, and then suddenly use cooling cooling, can improve the hardness and strength of steel; If heated to a temperature below the critical temperature at some point after slow cooling, the more resilient and make steel.
So if in order to obtain a more precise size of the workpiece and the surface is bright and clean, can adopt the way of no oxidation furnace for production, control of the oxidation burning loss of vacuum furnace is the key.

Vacuum bottom loading induction sintering furnace

Vacuum induction sintering furnace is a kind of intermediate frequency sintering induction heating equipment. Mainly for the sintering of copper-tungsten alloy, aluminum, nickel and cobalt permanent magnet, NdFeB, carbon fiber and graphite-based, carbon-carbon composite material, silicon carbide products, tungsten and molybdenum and other high-temperature sintering vacuum or atmosphere alloy material. The highest sintering temperature is up to 2550 ℃. Feature :
1. High automatic, it can be fully automation with the furnace model simulation display and real-time display device when running. It can be equipped with PLC controller and human-machine interface control system.
2.Very safe, using PLC to achieve security chain, with sound-light alarm when over-temperature, sensor burnout, over pressure of furnace and water, water flow, water temperature is too high .
3.Vacuum furnace can be equipped with a built-in or external fast-cooling system,improving the working efficiency
4.Energy-saving, special made coil and insulation structure, power output stability, high electrical efficiency.
5.It adopts the bottom loading, convenient charging and discharging .
