Vacuum dewaxing sintering furnace
Vacuum dewaxing sintering furnace is resistance heating furnace under vacuum or atmosphere condition. Its mainly used for carbide or powder metallurgy products dewaxing, pre-burning, sintering.
Scope of application:
Widely used in cemented carbide, ceramics, stainless steel materials, powder metallurgy, metal injection molding products and materials such as vacuum sintering dewaxing. It is characterized by a large pumping capacity, high vacuum, uniform temperature control and no leakage and so on. Other technical parameters can be designed and manufactured according to user requirements.
To compare with normal vacuum or hydrogen protective gas sintering furnace, This type of furnace can sinter and dewax cemented carbide or powder metallurgy product at one time in the same furnace, thereby saving power and reducing the oxidation of the sintered product Probability, so that the product quality is good, cost is low.
Degreasing, degassing, sintering integrated treatment furnace is equipped with sealed box, the degreasing volatile gas does not pollute the inner wall and heat insulation material, all discharged out of the furnace. Square sealed box structure can reduce the consumption of gas and heating power, reduce operating costs.
The cage heater makes the furnace temperature uniform, loading more, bigger constant temperature area. As the furnace temperature and vacuum are program automatically controlled, which is conducive to dewaxing and sintering process.
The furnace is horizontal double-layer water-cooled, the inner layer is stainless steel, out layer made of carbon steel. Internal with a circulating water system to ensure that the cooling rate to speed up. Furnace shell temperature close to room temperature, and with an additional rapid cooling system as well.
Furnace is equipped with graphite heating element or metal heating element. The door is opened on both sides of the furnace body, the front door is equipped with observation holes and insulation screen, the back door is equipped with open heat shield with a strong cold structure.
The furnace body is provided with a plurality of temperature measuring ports, For thermocouple or optical pyrometer to measure the temperature.
The side of the furnace body with a vacuum pipe which can connect the vacuum unit. At the same time, also equipped with vacuum measuring instruments and inflatable and venting device. Pipeline is also equipped with a perfect waxing collect device.
The control cabinet is equipped with indicator instrument, push button switch, signal light and temperature program controller. All functions of the temperature control table can be operated on the touch screen, built-in memory card, can be free to print out on the computer.
You can set the temperature curve and time setting directly on the touch screen panel. All electrical function control all through the touch screen to control, all the temperature curve can be transferred out at any time to print and save, historical data can save up to ten years. Thyristor phase shift voltage control heating, the end of the program automatically stop, no duty.
