Electric furnace during the welding process to go through high temperature corrosion, sometimes I need to turn the electric stove. Impacts by movement burden of wear and at the same time, the brick masonry hang off layer makes the temperature fluctuations, thus electric furnace to use high refractoriness, good alkali resistance corrosive, high crushing strength, good thermal stability of refractory materials.
Generally in furnace using magnesium or magnesium aluminum brick, brick calcining zone using good quality high alumina brick, or phosphate high alumina brick, other places use of clay brick, high temperature furnace, high temperature furnace, the experimental furnace refractory is relatively large influence on electric furnace.
Electric welding temperature to control in a certain range, the temperature too high or too low can cause the deformation and failure of welding materials.
