Design and application of secondary smoke hood for protective atmosphere electric slag furnace
The dust removal system of the protective atmosphere electric slag furnace directly discharges the dust and protective gas in the smelting chamber through the exhaust pipe on the smoke hood,and thus the air en-ters into the smelting chamber,resulting in the increase of oxygen content,which seriously affects the quality of the steel ingot.By designing a secondary smoke cover device,installed on the upper smoke cover,only collecting the dust and protective gas overflow from the upper smoke cover,it does not affect the protection atmosphere,meeting the requirements of environmental protection and smelting process.
