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 heating element, free heat radiation heating in the furnace cavity, energy saving and high efficiency, long service life
The heating element is heated in a ring or on two sides, so as to achieve good uniformity in the furnace
Dual zone heating, single temperature zone can control temperature independently, better temperature uniformity
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
PID with SSR/SCR control mode, precise temperature control
International standard thermocouple, long service life
Equipped with heating indicator light and over-temperature alarm buzzer
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
