The coal lance is the key equipment for the blast furnace coal injection, installed on the side of the tuyere blowpipe of the blast furnace and is a combustion device for injecting pulverized coal into the blast furnace tuyere. The lance barrel of the single barrel coal lance developed and produced by our company is made of 310S heat-resistant stainless steel, which prolongs the service life of the coal lance in high temperature environment; The bent lance head lined with ceramic and welded by argon arc at the front end of the coal lance improves the wear resistance of the head, at the same time, the pulverized coal stream is in the same direction as the hot air to avoid the tuyere from wearing caused by pulverized coal stream.
