Applications of Hydrogen Vacuum Sintering Furnaces
The reduction and high-temperature sintering of cemented carbide, refractory metal, metallized ceramics and powder metallurgy injection molded (MIM) products usually requires not only a regular vacuum sintering furnace, but also a hydrogen system for the relevant processes.
Hydrogen plays a crucial role in the hydrogen-flushed vacuum sintering furnace, primarily through chemical reduction and protective cleaning. It thoroughly removes oxides from the surface of metal powders and products, and prevents re-oxidation during high-temperature sintering, thus ensuring high purity, high density, and excellent mechanical properties of the product.
Parameters of Hydrogen Vacuum Sintering Furnaces
The RVS-335-M vacuum hydrogen sintering furnace control system uses a PLC for action control and an intelligent temperature controller for temperature control. Various advanced instruments are interlocked, ensuring accurate control and a high degree of automation. It allows for seamless switching between fully automatic and manual operation, remote wireless operation, and is simple and reliable to use. The specific process parameters are as follows:
