Vacuum sintering furnace what procedures?

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.

Excellent performance of vacuum furnace

         Excellent performance of vacuum furnace
The pressure inside the chamber of a stove or furnace smoke into industrial furnace is lower than the atmospheric pressure. Vacuum furnace heating power, the heated surface oxidation, no decarburization, small deformation, the mechanical performance is good. Use the vacuum furnace smelting metal to remove impurities, less finished pinhole, segregation of small, good quality. Vacuum furnace is suitable for the high quality, high purity, refractory metal melting and heating, such as tungsten, molybdenum, tantalum, niobium, titanium, heat-resistant alloy steel smelting and magnetic materials, electrical materials of high strength steel, stainless steel, tool steel and die steel, heat treatment.
Before and after vacuum furnace appeared in the 1930 s. In 1927 the United States made electrical material vacuum annealing furnace. Vacuum since 1953 arc furnace power consumption in industry have been used for melting titanium sponge. Before and after the '50 s vacuum induction furnace is widely applied in industry. In 1960 the United States developed oil quenching vacuum furnace.

How to pick a good vacuum furnace?

How to pick a good vacuum furnace?
Vacuum furnace varieties have a lot of, including vacuum furnace pressure type vacuum furnace, vacuum furnace, high pressure and high temperature type tubular vacuum furnace, etc., equipment, the corresponding use is also different, so how to choose a good vacuum furnace? Suitable vacuum furnace?
From the perspective of process, the design of vacuum furnace will make a good product. Vacuum heat treatment process can improve the service life of the parts, is the contemporary advanced heat treatment process, it has been generally recognized by the people.
Vacuum furnace parts heat treatment was conducted under the vacuum state, and completely avoids the problem of oxidation, the parts after vacuum heat treatment is more stable and reliable performance, has provided the safeguard for high precision workpiece.
When we were in the use of vacuum furnace, heat treatment process will face some problems in the vacuum furnace can't complete, investigate its reason, generally there are two aspects: one is the vacuum furnace manufacturer in accordance with the standards of vacuum furnace production of vacuum furnace, although the technical parameters of qualified, but not yet fully in the process of production of the vacuum furnace system to consider the heat treatment process, resulted in the vacuum furnace and heat treatment process parameters do not match. Second, vacuum heat treatment process was flawed, cannot achieve the desired results. In this respect we put the heat treatment process and vacuum furnace manufacturing organic unifies in together, the effect is obvious. Through understanding the process and details of each process, design and manufacture for vacuum furnace and heat treatment process and perfect fit, solved the trouble back at home for vacuum furnace users.
