Abstract
The utility model relates to a top blow type spray gun for desulfurization and dephosphorization, which belongs to the technical field of the spray gun for desulfurization and dephosphorization used for steel production. The utility model is composed of a connecting flange and a gun body, wherein the lower part of the connecting flange is provided with a protecting pipe, the inner side of which is provided with a spray pipe. The outer surface of the protecting pipe is provided with the grabbing and fixing hooks of refractory layers, and the outer surface of a fixing seat is provided with a mesh reinforcement. The refractory layers of the utility model can effectively grab the refractory layers to cause the refractory layers to be not easy to crack and fall off, the protecting pipe can protect the spray pipe from being heated for corrosion, so the working effect and the service life are enhanced. The utility model overcomes the defects of the existing products that the mesh reinforcement has not enough grabbing degree to the refractory material layers, the refractory material layers are easy to crack, cause the spray gun to extend the service life and is the ideal spray gun for desulfurization and dephosphorization.
Description
Technical field
The utility model belongs to the design and the manufacturing technology field of the desulfurization dephosphorization spray gun of steel-making usefulness.
Background technology
At present, the molten steel desulfurizing dephosphorization is a very the key link in metallurgical industry.The desulfurization dephosphorization effect directly influences the quality of steel.Be not very desirable the work-ing life of the sulphur dephosphorization spray gun that uses at present.Reason is that red-hot molten steel is very serious to the thermal etching of the body of a gun owing to after spray gun is extend into molten steel, and reinforcing mat causes flame retardant coating heat expansion cracking inadequately, comes off refractory masses degree of grabbing.Cause spray gun short work-ing life.Therefore say that present spray gun is not very desirable.
Summary of the invention
The purpose of this utility model provides a kind of top-blown desulfurization dephosphorization spray gun of long service life, to solve the practical problems that currently available products exists.
Structure of the present utility model is as shown in drawings: be made of the body of a gun and joint flange.In the joint flange bottom one pillar is arranged, a jet pipe is arranged in the pillar, jet pipe and pillar and joint flange are welded connection.On the pillar outside surface, have flame retardant coating and grasp hook.Pouring fireproof material layer around pillar.In the pillar bottom one permanent seat is arranged, pillar is held.The lower end of jet pipe is a spout.Using method of the present utility model is that joint flange is bound up on the desulfurization dephosphorization equipment, and the jet pipe catalyst outlet with desulfurization dephosphorization equipment suitable for reading is connected.Then the body of a gun is stretched in the molten steel, catalyzer is sprayed in the molten steel by spout.Finish the operation of spray catalyzer.The utility model is simple in structure, and is reasonable in design, owing to have pillar and flame retardant coating grasps hook, can protect jet pipe not to be subjected to thermal etching, and the solid hook of the flame retardant coating flame retardant coating of can holding effectively makes its not easy to crack coming off.Reach and prolong the spray gun purpose in work-ing life.
