Product Description

Product Description

The 1200°C tube furnace is used for the sintering and high-temperature heat treatment of new materials such as metal materials, ceramic materials, nano materials, semiconductor materials, and powder metallurgy in industries such as colleges and universities, research institutes, factories and enterprises, petrochemicals, aerospace, etc.

Furnace shell
1. The outer shell is made of metal Q235 low-carbon steel, with a surface that is resistant to static electricity and corrosion.
2. The sturdy double-layer metal frame combined with the heat-insulating fan structure results in a low surface temperature.
3. The horizontal usage method, with an upper-opening structure, is convenient.
Fire-resistant materials
Multi-layer insulation design, composed of lightweight alumina ceramic fibers and high-quality insulation boards as the backing, free of asbestos components, with low heat loss and low energy consumption.
Heating system
1. High-quality HRE spiral resistance wire heating elements are securely embedded in the surface of the furnace body. They are heated through free thermal radiation within the furnace cavity, achieving energy efficiency and long service life.
2. Ring heating is carried out through the resistance wire to achieve good uniformity within the furnace.
Temperature control panel
1. PID and SSR control mode, precise temperature control
2. International standard N-type nickel-chromium-silicon thermocouple, temperature measurement range is 0-1300°C, long service life
3. The furnace door is equipped with an opening power-off safety protection switch
Program controller
1. Advanced controller that meets complex process requirements
2. Simple and direct operation, flexible programming
3. 30 programmable program segments for a single curve
4. Over-temperature fault alarm, automatic safety protection
Vacuum atmosphere function
1. Utilizes 304 stainless steel sealing flanges, enabling the attainment of vacuum or atmosphere within the furnace tubes.
1. High-quality quartz glass working tubes are available, and metal or corundum working tubes can also be selected to accommodate different working conditions.
