Electric Arc Furnace Cover

High power and ultra high power electric arc furnace steelmaking proportion is increasing, steel smelting tempo is accelerating, therefore, electric arc furnace cover suffers more intense thermal radiation, thermal shock and dusts corrosion. So burned high alumina bricks can meet production requirement, furnace cover triangle zone is constructed by corundum castable, chrome alumina castable, corundum magnesia castable and precast blocks. The surrounding of triangle zone is built by sintered high alumina bricks, unburned high alumina bricks, magnesia bricks and magnesia chrome bricks.

Electric Arc Furnace Cover Introduction:

The prefabricated parts of the electric furnace cover are developed to prolong the service life of the electric furnace roof. There are two types: high-aluminum and corundum.

Electric Arc Furnace Cover Advantages:

1.Strong thermal shock
2. High temperature dust corrosion
3.Thermal shock and dusts corrosion

Electric Arc Furnace Cover Features:

Compared with ordinary brick electric furnace roof, it has the advantages of convenient construction, good integrity, strong arc radiation resistance, and rapid cooling and heating resistance. The preforms made of castables can be used after being baked at 400-600ºC, and the effect is good. The electrode ferrule is made of chromium corundum castable, which has strong radiation resistance;

The prefabricated parts of the electric furnace cover are developed to prolong the service life of the electric furnace roof. There are two types: high-aluminum and corundum. Compared with ordinary brick electric furnace roof, it has the advantages of convenient construction, good integrity, strong resistance to arc radiation, and resistance to rapid cooling and heating. The preforms made of castables can be used after being baked at 400-600ºC, and the effect is good. The use times of high aluminum is 80-110 times, and the use times of corundum is 160-220 times. The use of water-cooled structural forms such as water-cooled boxes, water pipes, etc. to make the electric arc furnace cover, the process technology that can significantly improve the service life of the furnace cover.

The water-cooled furnace cover of the refining furnace, the water-cooled structure in the furnace cover is composed of a plurality of seamless tubes 1 closely arranged. Each steel pipe is round. The water-cooled furnace cover of the refining furnace with this structure is not easy to leak water and is convenient for maintenance.

EAF roof prefabricated part is characterized by high strength, good thermal shock resistance, corrosion resistance, steady quality and long life, etc.
