1. Furnace body
The shell of the electric furnace is made of 3mm steel plate, and the bottom of the furnace is welded
with a channel steel frame structure. Furnace body structure is integral, firm structure.
2. Furnace lining
The furnace lining of this electric furnace adopts a structure combining refractory bricks and
refractory fiber cotton, that is, the furnace bottom is built with refractory bricks,
and the furnace body is made of refractory fiber structure.
Furnace bottom: built with refractory bricks, the lower layer of the furnace bottom is paved
with lightweight insulation bricks, and the upper layer is paved with three-grade high-alumina bricks,
which is convenient for the load bearing of workpieces.
Furnace body: It adopts full refractory fiber structure,and the thickness of refractory fiber is 330mm,
which has excellent energy-saving performance. Compared with brick resistance furnace of the same
specification, it can save energy by about 35%, and double the heating speed.
The service life is much longer than that of brick furnaces.
3. Heating element
The heating element of the electric furnace adopts 0Cr21Al6Nb high temperature resistant resistance band,
which is installed on the side wall and bottom of the electric furnace, and the resistance band is fixed
with special high alumina ceramic nails, which is firm and reliable. This hanging side structure has
high radiation efficiency, which strengthens the heat exchange in the furnace and improves
the thermal efficiency of the furnace. The heating elements of the electric furnace are all made of resistance bands,
with small surface load and long service life.
4. Furnace cover
The furnace cover is composed of a steel structure shell and a full-fiber lining. The thermal condition of the
overall frame ensures no deformation and is durable. Guarantee its long service life. The furnace cover
is hoisted, which is easy to operate and maintain.
5. Stainless steel liner
The stainless steel liner is made of 304 stainless steel, the head and the bottom cover,
the wall thickness is 10mm, the cover thickness is 8mm.
6. Temperature control system
The electric furnace is controlled in 3 zones. It is controlled by a 7-inch color touch screen smart meter
and a solid-state relay. The temperature control accuracy is high, the furnace temperature is stable,
and the temperature difference fluctuation is small, ensuring the safe and
reliable normal use of the electric furnace. The smart meter on the touch screen can be started with one key,
including the process curve storage function, and the temperature recording function of each zone.
The operation is more concise.
