Box-type muffle furnace special heating heat treatment equipment for scientific research experiment temperature normal temperature
Main uses: ceramics, metallurgy, electronics, glass, chemical industry, machinery, refractory materials, special materials, building materials, universities, scientific research institutes, industrial and mining enterprises for powder roasting, ceramic sintering, high temperature experiments, material processing, quality universities, scientific research institutes , Industrial and mining enterprises do high temperature atmosphere sintering, debinding, annealing, etc.
This high-temperature vacuum furnace uses high-quality resistance wire as the heating element, adopts a double-layer shell structure and a 31-segment program temperature control system, phase shift trigger, and thyristor control. The furnace is made of high-temperature alloy material, and the exterior is made of carbon steel for anti-corrosion. With a double furnace structure, the furnace has the advantages of balanced temperature field, low surface temperature, fast temperature rise and fall, and energy saving.
Voltage AC: 220V/380V
Heating power: depends on the size, please consult customer service for details
Furnace size: 300×200×200/400×300×300/500×400×400/can be customized according to requirements
Maximum working temperature: 1100°C
Common working temperature: normal temperature -1000℃
Temperature control accuracy: ±1°C
Temperature measuring element and temperature measuring range: K type thermocouple
Control method: Control method: It adopts a fully automatic temperature rise control system, which can run automatically after setting the program from room temperature to the set temperature. The system is controlled by thyristor, the temperature control system is modularized, the structure is simple, and the maintenance is convenient. It adopts Yudian electric instrument, thyristor control, program control, multi-stage power limit function, multi-group PID parameter self-tuning function, and can freely set constant temperature and heat preservation curve.
Heating rate: adjustable from 1°C/h to 20°C/min
Digital display: Measured temperature, set temperature dual display, heating power bar display
Number of programming curve segments: 31 adjustable segments, which can reduce unnecessary troubles caused by manual setting.
Control features: modular structure of the control system, long-life design of key components of the equipment, simple and reliable process, good stability and high precision.
Air-cooling system: The high-temperature-resistant fan impeller is directly installed on the bottom of the double-layer furnace shell and assembled with the control system. When the sintering furnace is heated, it is air-cooled, and the air-cooled motor is started, and the airflow blows rapidly from the fan to the furnace gallbladder at high speed. The interlayer of the furnace shell can further fully cool the circulating convective gas to speed up the cooling speed of the furnace body. The surface of the furnace shell The low temperature protects the operational safety of personnel and improves the effectiveness.
Heating element: high-quality resistance wire heating device
Insulation material: Alumina lightweight brick insulation material, the insulation layer is 150mm. ,
Shell: The furnace shell is welded by steel plates and profiles, and the shell is equipped with a detachable protective plate, which is electrostatically sprayed and baked. Fine workmanship, beautiful and generous.
Furnace structure: double-layer furnace shell structure, air-cooled circulation, lower shell temperature. Shell surface temperature < 55 ℃. The inner furnace is made of stainless steel, which can improve the heating efficiency of the equipment and prolong the service life of the instrument. The opening between the furnace door and the furnace body is connected by a hinge, and the seal between the furnace door and the furnace body is locked by a high-temperature resistant silicone ring and a stainless steel lock ring. The furnace leg is a figure-eight structure. Between the two legs, connecting plates and reinforcing plates are welded on the bottom steps on both sides to facilitate the horizontal movement of the equipment during installation.
Energy-saving performance: light weight, fast heating, energy saving of more than 50%, saving time and effort
