The vacuum sintering series equipment includes four categories: 9.1 horizontal double chamber type, 9.2 horizontal single chamber type, 9.3 horizontal single chamber dewaxing type, 9.4 horizontal single chamber pressure type;
Main purposes of vacuum sintering furnace:
It is widely used in scientific research units, military industrial units and other units, mainly for the sintering and processing of tungsten wire and other materials with high melting point, such as hard alloy, which are difficult to melt and knot under vacuum state and environment; Before using the vacuum sintering furnace, the water tank of the external circulating water cooling system must be filled with little and no impurities to ensure the safe operation of the vacuum sintering furnace.
Main advantages of vacuum sintering furnace:
Safety and environmental protection;
Good production flexibility, can stop and open the furnace at any time;
The surface quality of the workpiece is good, and the processing deformation is small;
High degree of equipment automation;
Low equipment maintenance cost.
Process control of vacuum sintering furnace:
Because of vacuum sintering, it is easy to control the carbon content of the alloy; It can improve the purity of cemented carbide; There are few impurities adsorbed on the surface of the hard phase, improving the wettability of the drill to the hard phase, and improving the strength of the alloy, especially the alloy containing TiC; The process is easy to operate. It can realize dewaxing sintering integration, reduce product oxidation, and reduce the difficulty of carbon control; Reduce the occupied area and labor intensity. It can realize the integration of multi atmosphere dewaxing and sintering, control the temperature, atmosphere and furnace pressure respectively by temperature section, achieve isothermal sintering (heat preservation) at any temperature, and complete various functions, such as gradient alloy sintering.

The vacuum sintering series equipment takes the category "9.3 horizontal single chamber dewaxing type" as an example to list the main parameters of the current standard type equipment

Note:
The above are the parameters of our standard equipment. Shenyang Dongbo can carry out non-standard design and manufacturing according to the specific requirements of customers to meet the customer's personalized needs. For example, the extreme vacuum degree can reach 10-4Pa or above; The pressure rise rate can be better than 0.1Pa/h, etc.
