The melting time of the furnace is 20-30 minutes, which greatly improves the efficiency of production.
The capacity of the furnace is increased, and the quality of the product produced in the same time unit is several times higher than before.

Is there any importance in vacuum sintering furnace fittings?

Is there any importance in vacuum sintering furnace fittings?

Vacuum sintering furnace consists of furnace body, furnace lining, burning device and drive parts, these are the necessary structure of vacuum sintering furnace, and in addition to these structures, vacuum sintering furnace and some accessories, vacuum sintering furnace accessories what then?
There are many kinds of vacuum sintering furnace parts, including pulse gas fuel oil burner, hot gas burner and assembly type thermocouple. So are these vacuum furnaces important? Today, suzhou qiaoshi vacuum furnace co., LTD. Briefly introduces these vacuum sintering furnace fittings.
Pulse gas fuel oil burner
The dual fuel burner allows all kinds of industrial gas and viscosity to burn well below 100 SSU. Switching from one fuel to another does not need to be removed or added to any element.
Hot gas burner
In dirty of unwashed heat generator gas as a fuel, combustion air by rotating the gushing and gas mixture flow more shares mixing and combustion stability, flame is shorter, easy to form the high temperature combustion zone, its heating ability is stronger. Because of the high air pressure than the gas pressure, telling blows air can according to the proportion of the gas suction, therefore, have certain ability to automatically adjust the burner itself.
The assembly type thermocouple
Fabricated thermocouple is commonly used in industry for measuring temperature transmitter, usually, and display instruments, electronic regulator and the recording instrument, it can be measured directly in the production of a variety of from 0 to 1800 degrees Celsius between the temperature of the liquid, gas and steam, such as medium, and the surface temperature of the solid. Fabricated thermocouple is usually by fixing device, temperature sensing element and the connection box parts together, can choose the models which are the main types: the S type, E type, type B, and K type.

The cold and high temperature sections are controlled by different temperature control elements, and the automatic switch is automatic. The cooling is cooled by natural cooling, and the cooling can be cooled by charging the inert gas.

How to maintain the vacuum sintering furnace

How to maintain the vacuum sintering furnace

A vacuum sintering furnace is a device that reduces the shape of an object or substance by heating it at high temperatures.It could reduce objects in space, grain boundary gradually gathered, solid particles gradually connection, so as to realize the density increases, the decrease of the object of the polycrystalline sintered body equipment.
How should vacuum sintering furnace be maintained in peacetime?
1, the import and export of the equipment, the driving bunker must ensure the clean and clean.
The cleaning of the discharge mouth will clean up the organic matter.
The main body of the chamber is to see if the pores are blocked.
If there is organic material on the lamp tube, it can be cleaned with non-woven or alcohol cotton.
The diagonal mesh band will be able to be softened and then scooped out when it is delivered 120.
The belt of the thimble can be polished with sandpaper to prevent damage to the battery.

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.
