Domestic experience of producing blow units for non-furnace steel treatment

The Terg-K Research-and-production company has developed blow units with ring contours and vertical slot channels, as well as a method for fastening the blow unit in a pocket block. Testing of the prototype blow units at the Magnitogorsk Metallurgical Works (MMW) have made it possible to estimate the specifics of the wear of domestic blow units compared to imported units and the reliability of the proposed blow lance designs. The testing has proved the possibility of steady operation of domestic slot-shaped blow units during 50 and more blowdown campaigns
