The powder metallurgy sintering furnace adopts special furnace structure and heater arrangement, and the furnace temperature uniformity is good.
The powder metallurgy sintering furnace adopts special structure degreasing box, which has good sealing effect and no pollution to the components inside the furnace.
The powder metallurgy sintering furnace has the functions of flexible vacuum pumping, vacuum sintering and micro positive pressure sintering.
Powder metallurgy sintering furnace uses the most advanced insulation structure and materials, the furnace gall insulation performance is good, less heat storage, energy saving than the traditional design of more than 20%.
The powder metallurgy sintering furnace adopts touch screen operation, PLC centralized control, simple operation and high reliability.
Powder metallurgy sintering furnace has the functions of over-temperature and over-pressure fault alarm, mechanical automatic pressure protection, action interlocking and so on. The equipment has high safety.
The powder metallurgy sintering furnace has the functions of remote operation, remote fault diagnosis and remote software upgrading.
In order to ensure the smooth progress of dewaxing (lubricant or shaping agent), reduction, sintering, alloying, densification and so on, the sintering temperature, protective atmosphere, billet conveying speed, heating and cooling speed should be adjusted and controlled. Therefore, the structure and function of the sintering furnace should meet the following five requirements:
1. litres have perfect dewaxing device or dewaxing belt.
2., it has air tightness, which can isolate the air outside the furnace and ensure the smooth protection atmosphere in the furnace.
3. the temperature in each section of the furnace is controllable, and the atmosphere in each section is adjustable.
4. for continuous sintering furnace, it has transmission device and adjustable transmission speed.
5. with a fast cooling device, the sintered parts can be cooled rapidly to a temperature that can be fired.
These are the five requirements for sintering furnace introduced by Xiaobian. As a special sintering equipment for powder metallurgical products, sintering furnace has a wide range of types. It is reasonable to choose and use sintering furnace correctly to ensure the quality of powder metallurgical parts.
