Electric Arc Furnace Cover

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.

During the filling of an Electric Arc Furnace (EAF), the electrodes are raised and rotate into their parked position. The cover of the EAF is then raised and rotated into a parked position for EAF loading. Mill Duty lever arm limit switches or proximity switches provide discrete outputs when vertical and rotational movement reaches a programmed parked position. These switches often fail every three to four months and adjustment of the actuation points can only be done when the furnace is not operating which leads to large blocks of downtime.

Electric Arc Furnace Cover Advantages:

1.Strong thermal shock

2. High temperature dust corrosion

3.Thermal shock and dusts corrosion
