Furnace shell
The shell is made of metal Q235 low-carbon steel, and the surface is electrostatically resistant and resistant to corrosion.
The solid double-layer metal frame is combined with the heat-insulating fan structure, and the furnace surface temperature is low
Horizontal use mode, upper opening structure, easy to operate
Refractory material
Multi-layer insulation design, composed of lightweight alumina ceramic fiber and high-quality insulation board backing, does not contain asbestos components, low heat loss and low energy consumption
Heating system
High-quality HRE spiral resistance wire heating element is safely and firmly embedded on the surface of the furnace, and is heated by free heat radiation in the furnace cavity, which is energy-saving and efficient, and has a long service life
Ring heating by resistance wire to achieve good uniformity in the furnace
Temperature Control Panel
PID and SSR control mode, precise temperature control
Internationally standardized N-type nickel-chromium-silicon thermocouple with a temperature measurement range of 0-1300℃ and a long service life
The furnace door is equipped with a door-opening power-off safety protection switch
Program Controller
Advanced controllers that meet complex process requirements
Simple and direct operation, flexible programming
Programmable 4 curves, 8 program segments for a single curve
Over temperature and fault alarm, automatic safety protection
Vacuum Atmosphere Function
With 304 stainless steel sealing flange to obtain vacuum or atmosphere in the furnace tube
High-quality quartz glass working tube, and metal or corundum working tube can also be selected to adapt to different working conditions
