Problems solved by technology
[0002] At present, the middle sleeve of blast furnace tuyere is made of pure copper material with excellent thermal conductivity. This material has high thermal conductivity, but its disadvantage is its low strength. The deformation of the furnace wall during the operation of the blast furnace directly acts on the The middle sleeve of the tuyere is put on to make it deform under pressure. In addition, the middle sleeve of the tuyere is also affected by the push and pull force when the small tuyere sleeve is frequently replaced. The reduced contact area may easily cause gas leakage in the furnace and seriously affect the normal operation of the blast furnace

Embodiment Construction
[0012] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0013] Such as figure 1 and figure 2 As shown, a middle sleeve of a blast furnace tuyere includes a body 1 and a front cap 2. The steel body 1 and the copper front cap 2 are welded together to form a sleeve in the shape of a small front end and a large cone at the rear end. The inside of the sleeve has a ring Cooling chamber 6, the rear end of the sleeve is provided with a water inlet 4 and a water outlet 5 connected to the cooling chamber 6, and the outer tapered surface of the rear end of the sleeve is an annular surfacing layer 3 made of copper alloy; the thickness of the annular surfacing layer is 4mm.

The invention discloses a blast furnace tuyere medium sleeve. The blast furnace tuyere medium sleeve comprises a body and a front cap, the steel body and the steel front cap are welded together to form a sleeve in a shape of conical cylinder with small front end and big rear end, an annular cooling cavity is formed in the sleeve, the rear end of the sleeve is provided with a water inlet and a water outlet communicated with the cooling cavity, and the outer conical surface of the rear end of the sleeve is provided with an annular build-up welding layer made of pure copper or low-alloy copper alloy material. The blast furnace tuyere medium sleeve is formed by mainly welding the steel body and the steel front cap, so the blast furnace tuyere medium sleeve has high supporting strength, is not easily extruded by a furnace wall to deform, can save over 2 / 3 of noble metallic copper material and greatly reduces the cost of the material. Meanwhile, the blast furnace tuyere medium sleeve has good cooling and heat dissipation effects, the sealing property of fitting surfaces of a tuyere big sleeve and the tuyere medium sleeve is ensured, and the tuyere big sleeve is prevented from being abraded.
Description
technical field [0001] The invention relates to a spare part of an ironmaking blast furnace, in particular to a tuyere middle sleeve of a blast furnace. Background technique [0002] At present, the middle sleeve of blast furnace tuyere is made of pure copper material with excellent thermal conductivity. This material has high thermal conductivity, but its disadvantage is its low strength. The deformation of the furnace wall during the operation of the blast furnace directly acts on the The middle sleeve of the tuyere is put on to make it deform under pressure. In addition, the middle sleeve of the tuyere is also affected by the push and pull force when the small tuyere sleeve is frequently replaced. The reduced contact area will easily cause gas leakage in the furnace and seriously affect the normal operation of the blast furnace. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a blast f...
