Do you know the function of vacuum sintering furnace?
Vacuum sintering furnace is a kind of furnace for protective sintering of heated articles in a vacuum environment. There are many heating methods, such as resistance heating, induction heating and microwave heating. It is a furnace that USES induction heating to perform protective sintering on heated articles, which can be divided into power frequency, medium frequency, high frequency and other types, and can be classified as a subclass of vacuum sintering furnace.
Vacuum sintering furnace is a complete set of equipment which USES the principle of medium frequency induction heating to realize sintering of cemented carbide tool heads and various metal powder compaction bodies. It is designed for the industrial production of cemented carbide, dysprosium metal and ceramic materials. The specific structure and performance of the furnace are described as follows:
1, the sintering furnace to sinter the tank adopts wet glazed, one with a burning process, the sintering temperature is 840 ~ 880 ℃, the drying temperature of 100 ~ 150 ℃, the sintering time about 8 ~ 10 min. Sintering furnace (including drying furnace) installed power 850KW(5%); The energy consumption of kiln machinery and fan is about 25KW; The standby heater power of drying line is 60KW.
2. The vacuum sintering furnace adopts shaped steel structure. The main insulation material is 1050 grade aluminum silicate fiber, the thickness of the high temperature zone is 340mm; Medium temperature zone thickness 200mm; The low temperature zone is insulated with 100K mineral wool felt. And specially designed air insulation layer and aluminum foil insulation reflective layer. The appearance of furnace body is installed with 0.75mm color corrugated steel plate, which is beautiful and durable.
3, the device 8 internal circulation type stainless steel air curtain machine (measuring the noise of the air curtain machine from one meter away is no more than 85 db), blocking the heat flow overflow, uniform furnace temperature.
4. American heater with corundum mullite tube. The heating element is 0Cr25Al5. High temperature resistance, good insulation, long life, low maintenance cost. Arranged evenly inside the furnace, the heater temperature measurement point (20) one more, make more uniform temperature in furnace, furnace mainly in temperature difference of + / - 5 ℃.
5. The heating time of the product in the heating zone of the vacuum sintering furnace is guaranteed to be 8 ~ 10 minutes. The porcelain glaze is fully fused to improve the quality. The furnace heating time is about 90 minutes. The products are cooled by air blast to improve operating conditions.
