1400 ℃ tube furnace is used in sintering and high temperature heat treatment of metal materials, ceramic materials, nano materials, semiconductor materials, powder metallurgy and other new materials in colleges and universities, scientific research institutes, factories and enterprises, petrochemical, aerospace and other industries.


Furnace shell

  1. The shell is made of metal Q235 low-carbon steel, and the surface is electrostatically resistant and resistant to corrosion.
  2. The solid double-layer metal frame is combined with the heat-insulating fan structure, and the furnace surface temperature is low
  3. 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

  1. High-quality HRE heating element, free heat radiation heating in the furnace cavity, energy saving and high efficiency, long service life
  2. The heating element is heated in a ring or on two sides, so as to achieve good uniformity in the furnace
  3. Dual zone heating, single temperature zone can control temperature independently, better temperature uniformity

Temperature Control Panel

  1. PID and SSR control mode, precise temperature control
  2. Internationally standardized N-type nickel-chromium-silicon thermocouple with a temperature measurement range of 0-1300℃ and a long service life
  3. The furnace door is equipped with a door-opening power-off safety protection switch

Program Controller

  1. PID with SSR/SCR control mode, precise temperature control
  2. International standard thermocouple, long service life
  3. Programmable 30 program segments
  4. Equipped with heating indicator light and over-temperature alarm buzzer

Vacuum Atmosphere Function

1.With 304 stainless steel sealing flange to obtain vacuum or atmosphere in the furnace tube

  1. High-quality quartz glass working tube, and metal or corundum working tube can also be selected to adapt to different working conditions

Sealing performance

Both ends of the furnace tube are equipped with stainless steel metal flanges, matched with high-temperature PTFE gaskets, which can work under vacuum with a vacuum degree of ≤5pa (rotary vane vacuum pump)

atmosphere performance

There are air inlets and outlets at both ends of the flange. The pressure gauge is installed on the metal flange. The precision needle valve can adjust the air intake and output, and can be fed with protective gases such as nitrogen, argon, and hydrogen.

equipment protection

Modular control, sound and light alarm signal will be sent out for over temperature and broken coupler in the working process, and the protection action will be completed automatically

safety protection

The equipment is equipped with a circuit breaker, which will automatically pop open in case of short circuit leakage, which can protect the safety of equipment and operators
