Thread Content

2005 Inventors: Shi Enping, Yao Jiliang; Applicants: Shi Enping, Yao Jiliang; Utility Model Application Number: CN200520091538.4 Top-blown desulfurization and dephosphorization gun, belonging to the field of design and manufacturing of desulfurization and dephosphorization guns for steelmaking. It consists of a connecting flange and a gun body; the lower part of the connecting flange is equipped with a protective tube, inside which there is a nozzle, and the outer surface of the protective tube features fire-resistant layer gripping hooks. The outer surface of the fixing base is equipped with a steel mesh. The fire-resistant layer of this product can effectively hold the structure together, preventing it from cracking or falling off. The protective sleeve safeguards the nozzle from thermal corrosion, thereby improving operational efficiency and extending its service life. It overcomes the drawbacks of existing products, namely the insufficient grip of the rebar mesh on the refractory layer and the tendency to crack, thereby extending the service life of the spray gun. It is an ideal desulfurization and dephosphorization spray gun.
