The bonding furnace is composed of furnace body, heating chamber, vacuum system, charger system, air cooling circulation system, electric control system, pneumatic system, water cooling system and material truck.
When the bonding furnace is working, the assembled workpiece is transported to the furnace by truck, and then the furnace door is closed and automatically locked, and the whole heat treatment process such as vacuum, heating and cooling is controlled by a preset program.
Bonding furnace is widely used in universities, scientific research institutes and mining enterprises for sintering, melting, analysis, production of ceramics, metallurgy, electronics, glass, chemical industry, machinery, refractory materials, new material development, special materials, building materials, metal, non-metal and other chemical and material materials developed special equipment.
What are the main advantages of bonding furnaces?
(1) Reduce the adverse effects of harmful components in the atmosphere (water, oxygen, nitrogen) on the product. For example, it is very difficult to reduce the water content to 140 dew point in the electrolysis of hydrogen, and when the vacuum degree reaches 133Pa, it is equivalent to the dew point of 140 water content. It's not hard to get that vacuum.
(2) Reducing or inert gases cannot be used as a protective atmosphere (such as the sintering of active metals), and materials that are prone to decarburization, carburization, and carbon can be used as vacuum sintering.
(3) The bonding furnace helps to improve the wettability of the liquid relative to the solid, shrink and improve the alloy structure.
(4) Bonding furnace sintering helps to discharge impurities such as silicon, aluminum, magnesium, calcium or their oxides, and plays a role in purifying materials.
(5) The bonding furnace helps to exclude the adsorbed gas, the residual gas in the hole and the reaction gas products, and has a significant effect on promoting the shrinkage of the later sintering period. The porosity of vacuum sintered cemented carbide is significantly lower than that of hydrogen sintered cemented carbide.
