Product Description

Precision High Temperature Furnaces

General overview of equipment:
Main uses: ceramics, metallurgy, electronics, glass, chemicals, 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, atmosphere reduction, CVD experiment, vacuum annealing, etc. 
This furnace uses silicon carbide rods as heating elements, adopts a double-layer shell structure and a 31-segment program temperature control system, phase-shifting trigger, and thyristor control. The furnace uses all imported high-purity alumina fibers and vacuum-formed fiber poly light board. material. It adopts double hearth structure. The furnace has the advantages of balanced temperature field, low surface temperature, fast temperature rise and fall, and energy saving.
Adopting international advanced technology, self-developed high-performance, high-energy-saving new type, using energy-saving ceramic fiber material double-layer structure, can reduce the external temperature to normal temperature and make the internal cavity temperature uniform.
Main technical parameters:

Parameter Item	TOB-X1100-30S
Voltage AC	220 V
heating power	3KW
Furnace chamber size(mm)	300x200x120mm
Maximum working temperature	1100ºC
Long-term working temperature	≤1000ºC
heating stuff	Ni-Cr alloy wire
Heating rate	1-20ºC/min Adjustable
Suggested heating rate	5-8ºC/min Temperature rise rate
Temperature control accuracy	±1ºC
Temperature measuring element and temperature range	K thermocouple,The temperature measurement range is 0-1200ºC, and the thermocouple is close to each other, which can reduce the surface temperature to normal temperature and make the temperature distribution in the cavity uniform.
Original electrical appliances	Partial selection of imported brands
Instrument control	Yu dian GP518P
Control methood	Control method: adopts a fully automatic control system, which can run automatically after setting the program from room temperature to set temperature. The system can be controlled by thyristor, and the temperature control system has a modular design, simple structure and convenient maintenance. Adopt Yudian instrument, imported thyristor control, programmable 31 segments, multi-segment power limit function, multi-group PID parameter self-tuning function, freely set constant temperature and heat preservation curve, non-interference switching function, instrument has temperature correction and compensation Features.
Programming curve segment number	31 segments are adjustable, which can reduce unnecessary trouble caused by manual setting.
Display accuracy	±1ºC
Digital display	Measure temperature, set temperature dual display
Control characteristics	The control system has a modular structure, a long-life design for key parts of the equipment, simple and reliable process, good stability and high precision.
Air cooling system	The fan impeller is directly installed at the bottom of the double-layer furnace shell and assembled with the control system. Air cooling is performed when the sintering furnace is heated, which can reduce the surface temperature of the furnace shell and protect the heat dissipation of electrical appliances, making the operation safer for personnel and improving efficiency.
Refractory	Furnace lining is made of imported high-purity alumina fiber, vacuum forming fiber poly light board material, light hollow spherical alumina board, high temperature, low heat storage, resistance to rapid heat and cold, no cracks, no slag, and good heat preservation performance (The energy saving effect is more than 80% of the old electric stove). The patented double furnace structure not only has a fast heating speed, but also has the patented characteristics of being strong and durable, and will not collapse after long-term use.
Insulation Materials	Imported alumina multi-fiber insulation material, the insulation layer is 150mm.
Shell	The furnace body and the furnace shell are welded by steel plates and profiles, and the shell is equipped with removable protective plates, which are electrostatic sprayed and painted. Fine workmanship, beautiful and generous.
Furnace structure	Double-layer furnace shell structure, air-cooled circulation, lower shell temperature. Shell surface temperature <60 degrees The surface of the inner furnace is coated with a high-temperature alumina coating to improve the heating efficiency of the equipment and also extend the service life of the instrument.
Energy saving performance	Light weight, fast heating, energy saving more than 50%, saving time and effort.
spare parts with equipment	One manual, one certificate, one crucible tongs, one pair of high temperature gloves
