At present, the domestic electric furnace equipment accounts for 85% of the domestic electric furnace capacity, and the imported electric furnace accounts for 15%. Although domestic manufacturers have certain strength in single equipment, and electric furnace equipment below 100 tons has basically been localized, Chinese scientific and technological workers have also been committed to developing complete sets of electric furnace equipment with independent intellectual property rights.

The furnace top, also known as the furnace cover, is in a circular arch shape and can be moved. The outer ring is a water-jacketed steel structure. During the smelting process, the furnace roof (especially the central part of the furnace roof, around the electrode hole and the dust removal hole) is at high temperature for a long time. The state of the furnace is also affected by sudden changes in temperature. The chemical corrosion of furnace gas and slagging powder, the radiation of electrode arc and the erosion of smoke and dust, the dust on the furnace roof also produces pressure and hinders heat dissipation. The furnace roof is also subject to mechanical The function of vibration, the working conditions are very bad, it is the weak link of the whole furnace lining.
