Factory Supply Vacuum Sintering Furnace With Good Quality

Factory supply vacuum sintering furnace with good quality is a type of furnace that uses the principle of medium frequency induction heating to generate high temperature in the tungsten crucible inside the coil under the protection of hydrogen gas after vacuum pumping, and conducts it to the work through thermal radiation. It is suitable for scientific research and military units to shape and sinter powders of refractory alloys such as tungsten, molybdenum, and their alloys. There are two types of electric furnaces: horizontal vacuum sintering furnaces and vertical vacuum sintering furnaces. The installation of electric furnaces should meet the requirements of vacuum hygiene, the surrounding air should be clean and dry, and there should be good ventilation conditions. The workplace should not easily raise dust, etc.
Factory supply vacuum sintering furnace with good quality is mainly used for the sintering process of semiconductor components and power rectifier devices. Factory supply vacuum sintering furnace with good quality can perform vacuum sintering, gas protection sintering, and conventional sintering. It is a novel process equipment in the semiconductor equipment series. Its design concept is novel, operation is convenient, and the structure is compact. Multiple process flows can be completed on the equipment. It can also be used for vacuum heat treatment, vacuum brazing and other processes in other fields.

FAQ:

Q: What are the factors affecting sintering?
A: The main factors that affect the sintering of refractory materials include the nature of the raw materials, additives, sintering temperature and holding time, firing atmosphere, and molding method and pressure of the green body.
Q: What is the effect of time on sintering?
A: With the increase in sintering time, the ceramic particles contin- ue to grow and the sizes of the three-dimensional pores in- crease. With the increase of sintering time, the porosity of the sample decreases first and then increases, and the com- pressive strength increases first and then decreases.
Q: Which is the fastest process of sintering?
A: Field Assisted Sintering Technique (FAST) is an emerging manufacturing technology that offers higher heat rates, lower sintering temperature, and faster times than conventional consolidation processes.
Q: How does sintering time affect density?
A: The results showed that with the increase of temperature and sintering time, the density of the samples increased from 91.11 % to 96.53 % and the hardness of the specimen improved from 536 Hv to 1433 Hv due to lower porosity (higher density of a sample with increasing sintering temperature) in the samples.
Q: How much power does a sintering furnace consume?
A: The average energy for the sintering process based on data from various plants can be estimated as ,1.8 kWh kg21. In addition to the direct energy consumption to heat gases in the sintering furnace, other energy balances are associated with gases during sintering.
Q: What is a high temperature vacuum sintering furnace?
A: They are also used for different high - temperature processes such as carburisation, recrystallisation, silicon infiltration, nitridation (formation of Si3N4), vacuum sintering or metallisation. Available volume: 1 dm³ to 10 m³ at max. temperatures of 2800 °C.
Q: What is vacuum heat treatment?
A: Over time, any material absorbs the air it is exposed to along with the dust and water vapor the air contains. The material reacts chemicall
