Application

Submerged arc furnace-it's also known as electric arc furnace or resistance electric furnace,It is mainly used to reduce smelting ore,carbonaceous reducing agent and solvent etc. mainly adapt to production of ferrosilicon, ferromanganese, ferrochrome,ferrotungsten,silicon manganese alloy and other ferrous alloys,it is an important smelting furnace in metallurgical industry for production of industrial raw materials and calcium carbide and so on chemiacal raw materials.

 

Features

Furnace body of submerged arc furnace (SAF).
According to the electrode arrangement in the submerged arc furnace (SAF), the furnace type of the submerged arc furnace has the electrode triangular arrangement type, which includes a circular furnace and a triangular furnace;
Electrode linear arrangement type, it includes rectangular furnace and oval furnace.
The shape of the furnace body depends on the arrangement of the electrodes. Most of the three electrodes in a row

and the six electrodes in three phases are rectangular or elliptical furnace bodies;
A round furnace body is commonly used, which has a compact structure, high rigidity and is easy to manufacture.
The temperature of the reaction zone of the molten pool of the reduction furnace is as high as 2000-2200 ºC, and it is

in a strong electric field. The refractory material needs to have high refractoriness and good physical and chemical indicators.

The refractory material needs to have high refractoriness and good physical and chemical indicators.
Commonly used refractory materials are clay bricks, carbon bricks, magnesia bricks, etc.
There is a gap of about 90-140mm between the furnace shell and the refractory brick, and the clay particles and

asbestos board are filled as an elastic layer to partially absorb the expansion of the refractory brick and reduce the

heat dissipation of the furnace lining.
The furnace shell is welded or riveted by 15-25mm thick steel plate and vertical and horizontal stiffening plates.
The side walls are equipped with tap holes, 1-2 for the stationary electric furnace and 5-6 for the rotary electric furnace, the latter is beneficial for the furnace body to rotate to any position for tapping.
The bottom plate of the furnace is usually a horizontal plate, which is floated on the I-beam bent frame placed on the concrete foundation, and a good air passage can be formed through the I-beam bent frame to cool the furnace bottom.
The rotary furnace body is conducive to loosening the charge during the smelting process to increase the permeability, expand the reaction area and prolong the life of the furnace lining, and is mostly used in electric furnaces that produce high silicon alloys.
