Muffle furnace

Split type muffle furnace

Box type resistance furnace（Muffle furnace）Electric furnace for periodic operationThere are various specifications including high temperature, medium temperature, etcIt can be used for chemical analysis, physical determination, and general small steel parts in laboratories of industrial and mining enterprises, scientific research institutions, and other unitsQuenching, annealing, tempering and other heat treatments, as well as heating for metal sintering, melting, analysis, etc.

This series of resistance furnaces is equipped with a temperature controller andPlatinum rhodium heatingElectric couple, capable of measuring, indicating, and automatically controlling furnace temperature.

Muffle furnaceStructure Introduction:

This series of resistance furnace shells are made of thin steel plates that are folded and welded, and the surface is treated with electrostatic spraying. The inner lining is a rectangular integral lining made of aluminum silicate refractory material.

The spiral heating element made of iron chromium aluminum alloy is threaded through the wire grooves on the upper, lower, left, and right sides of the inner furnace lining. The furnace lining is a sealed structure.

The door bricks of the electric furnace are made of lightweight refractory materials, and the inner lining is formed by firing high alumina bricks. The insulation layer between the lining and the furnace shell is made of refractory fibers and expanded perlite products.

For temperature measurement purposesPlatinum rhodium heatingElectric thermocouple, inserted through the thermocouple hole after the electric furnace. Temperature control instruments and controllers are used together with the furnace, with high temperature control accuracy and easy operation

Heating with nickel chromium alloy resistance wire below 1200 degrees Celsius, with resistance wire surrounding the furnace and uniform temperature

Heating below 1300 degrees using silicon carbide rods, with the rods exposed inside the furnace, doubles the heating effect

Characteristics of split type machines

The furnace body and temperature controller need to be connected by themselves，You need to wire it yourself, you can place it according to your location

Using AC contactors, there is a certain level of noise compared to the integrated machine
