The three heating zone tube furnace is used in sintering and high-temperature heat treatment in the fields 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 metal and ceramic 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. Three heating zone, single temperature zone can control temperature independently, better temperature uniformity

Temperature Control Panel

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

Program Controller

  1. Advanced controllers that meet complex process requirements
  2. Simple and direct operation, flexible programming
  3. Programmable 30 program segments
  4. Over temperature and fault alarm, automatic safety protection

Vacuum Atmosphere Function

  1. With 304 stainless steel sealing flange to obtain vacuum or atmosphere in the furnace tube
  2. High-quality quartz glass working tube, or metal or alumina working tube can be selected to adapt to different working conditions
