Our company provides long-term vacuum furnace spare parts and installation&debugging services,we promise to choose high quality spare parts,give customers reasonable price, timely delivery and satisfying service!
TECHNOLOGY AND INNOVATION
1. Europe standard high Pressure vacuum gas quenching furnace
In 2016,our company produces high-pressure vacuum gas quenching furnace for export to Europe.The products are produced strictly according to CE safety standards and PED pressure vessel standards.The equipment standard is far higher than the domestic relevant standards,and the 6bar cooling speed of the equipment can reach the domestic conventional 8bar cooling speed.
2. Vacuum brazing furnace with 1550℃
According to the customer’s request ,our company has customized a 1550℃ high-temperature vacuum brazing furnace for the Iron and Steel Research Institute and the People’s Liberation Army 4723 factory.The equipment uses high-temperature molybdenum-niobium alloy as the heating element and thermal insulation layer,through unique anti-pollution and the anti-high temperature deformation design greatly extends the use effect and life of the equipment.
3. Multifunction Laboratory vacuum furnace
In order to better meet the experimental needs of universities and research institutes,and to cope with the current situation of small equipment,many varieties of materials,high automation requirements,imperfect supporting facilities,etc.,our company has developed a small modular muti-functional experimental furnace.The equipment is compact in structure and can be adapted to the small space of the laboratory.At the same time,the equipment is equipped with related auxiliary equipment,which can realize the following treatment processes:
(1). Vacuum bright annealing (2). High temperature vacuum brazing
(3). Vacuum tempering (4). Vacuum gas quenching (5). Vacuum sintering
(6).Vacuum hot-pressing sintering (7). Vacuum diffusion welding
4.Updated vacuum aluminium brazing furnace
Vacuum aluminum brazing furnace is a mature product on the market,but it exists in the process of use,high maintenance frequency,high oil return rate and poor stability.In view of the above problems,our company has improved the heating chamber and cold trap structure.The more optimized scheme improves the vacuuming rate of the equipment ,and the effect is good.It has been recognized by the customers.At present,the vacuum aluminum brazing furnace for large-scale air separation equipment is designed and manufactured,and the effective area reaches 6800mm(L)×1700mm(W)×2000mm(H)
5. Large vacuum annealing furnace
Vacuum annealing can effectively solve the problems of oxidation and decarburization during the treatment process,and the temperature rise and fall rate can be adjusted,which greatly helps the performance improvement of the product,and reduces the secondary process in production.Our company is a large-scale vacuum annealing furnace customized by HEYE Technology Co.,Ltd.,with an effective area of 5500mm(L)×1300mm(W)×1300mm(W),and the maximum installed capacity can reach 6 tons.It not only solves the decarburization and oxidation problems at the customer site,but also reduces the pickling process and saves the use cost.
6. Oil filter for vacuum furnaces
mp group.Our company independently develops the soot filter device for vacuum pump,which can effectively remove the fumes during use,meet the national environmental protection requirements,and eliminate the need for exhaust pipes to ensure the cleanliness of the site and the workers’ physical and mental health.
At present,our company has 10 utility model patents,such as quick release thermocouple device,furnace door fixing device,furnace door automatic limit device,furnace door automatic tightening device,vacuum gas quenching furnace air cooling system,soot filter device,vacuum gas quenching furnace round heating chamber sealing belt,square vacuum gas quenching furnace heating chamber sealing belt applied for relevant patents,the second batch of utility models and invention patents are in the process of application.
