1200°C Three Zone Vertical Tube Furnace

Description

1200℃ three zone vertical 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.

Features

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
Vertical use mode, side open cover 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
Divided into three temperature zones, each temperature zone can be heated independently

Temperature Control Panel

PID with SSR/SCR control mode, precise temperature control
Internationally standardized N-type nickel-chromium-silicon thermocouple with a temperature measurement range of 0-1300°C 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 30 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 alumina working tube, or metal or quartz glass working tube can be selected to adapt to different working conditions
