Vacuum sintering furnace what procedures?

Vacuum sintering furnace is mainly in a vacuum or protective atmosphere conditions, by using the principle of intermediate frequency induction heating, let the hard alloy cutter and a variety of metal powder compacting sintering of implementation of a complete set of equipment, is specially designed for hard alloy, ceramic and metal industrial production and design, it is in the face of the heated object in vacuum environment protective sintering furnace, vacuum sintering furnace heating mode is very much, have induction heating, resistance heating and microwave heating and so on.
Based on rich experience of vacuum sintering furnace operating personnel to the manufacturer's recommendations, some industrial manufacturers will develop some vacuum sintering furnace operational procedures, so what is the vacuum sintering furnace operation procedures? Actually, these regulations is before operating the equipment, check equipment above some of the commonly used spare parts if there are any problems, in order to avoid an accident, is mainly in order to ensure the safety of operating personnel and improve the working efficiency of the equipment.
1, vacuum sintering furnace must be full of the inside of the reservoir water, and water there can be no impurities. Start the pump, intermediate frequency power supply, furnace cooling system and vacuum furnace sensor circulation normal, and adjust the water pressure, its control above the value of the rules.
2, check the power of the vacuum pump system, vacuum pump oil is already inside the oil seal the centerline of the observation hole. Check after the artificial the rotation of the vacuum pump pulley, if there is no exception, can under the condition of the closing butterfly valve, vacuum pump.
3, check the internal condition of vacuum sintering furnace, furnace body within the level of health, the induction coil, better insulation, vacuum sealing tape to have certain elasticity, and size to be qualified. Check the vacuum sintering furnace of flexible lever handle is started.
4, after the requirements of the vacuum degree reach, start frequency, adjustment of intermediate frequency power, according to the relevant provisions of sintering operation. After sintering, the stop frequency, press the stop frequency conversion switch, inverter to stop working, the intermediate frequency power supply points total brake brake and power off.
5, from inside the furnace of the observation hole observation, in the event of a stove or furnace black, then turn off butterfly valve, vacuum pump and disconnect current of vacuum pump, and then use tap water to cooling and induction coil, furnace, finally to stop the pump.
