Vacuum sintering cemented carbide is the main production process

Vacuum dewaxing sintering furnace can be a one-time degumming, sintering, cooling and molding charge of a full set of technical process. In the traditional drying sintering furnace structure added a graphite on the basis of the tank, and low voltage carrier gas dewaxing process is adopted to be collected wax device isolated after bonding (molding) agent, residual gas in a variety of ways.
With the above process, forming agent is not in the oven and it touches a cold surface accumulated inside the furnace, also won't pollution insulation and heating element. Vacuum sintering cemented carbide is the main production process, the sintering process for vacuum dewaxing sintering furnace temperature must be integrated according to the corresponding to the sintering products in the process of sintering temperature curve to carry on the control, the tracking error and overshoot amount have strict index requirements.
