Abstract
The utility model discloses a tuyere medium jacket of a blast furnace, which comprises a body and a front cap, wherein the steel body and the copper front cap are welded together to form a conical sleeve with a small front end and a big rear end; an annular cooling cavity is arranged in the sleeve; the rear end of the sleeve is provided with a water inlet and a water outlet which are communicated with the cooling cavity; and the outer conical surface of the rear end of the sleeve is an annular surfacing layer made of pure copper or low-alloy copper alloy material. The tuyere medium jacket of the blast furnace is mainly formed by welding the steel body and the copper front cap, therefore, the tuyere medium jacket of the blast furnace has high supporting strength, is not easy to be extruded by a furnace wall to deform, can save more than 2/3 of a noble metal copper material, greatly decreases a material cost, further has good cooling and heat-radiating effects, guarantees the tightness of the matching surfaces of a tuyere big jacket and the tuyere medium jacket, and guarantees that the tuyere big jacket is not worn.
Description
Technical field
The utility model relates to a kind of iron-smelting blast furnace spare part, overlaps in especially a kind of blast-furnace tuyere.
Background technology
At present, blast furnace is selected the fabulous pure copper material of thermal conductivity for use with cover in the air port, and this material has higher thermal conductivity; But intensity is low to be its inferior position, the furnace wall that occurs in operation of blast furnace process distortion, and this power acts directly in the air port and puts; Make its compressive deformation; When the frequent change tuyere small sleeve, overlap the influence that also will receive push-pull effort in addition in the air port, these situation all can cause cover outer cone distortion in the air port, and the contact area of cover and big cover mating surface reduces in making; Be prone to cause gas leak in the stove, have a strong impact on the normal operation of blast furnace.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, provide a kind of simple and reasonable, with low cost, bulk strength is high, be difficult for overlapping in the good blast-furnace tuyere of deformable seal property.
The purpose of the utility model is achieved in that in a kind of blast-furnace tuyere overlaps; It comprises body and preceding cap; It is characterized in that: cap is welded together to form the sleeve of the little rear end of front end auger barrel shape before steel body and the copper material; There is annular cooling chamber telescopic inside, and sleeve rear end is provided with water-in and the water outlet that is communicated with cooling chamber, and the sleeve rear end male cone (strobilus masculinus) is the annular stack layer of fine copper or low-alloy copper alloy material.
The thickness of said annular stack layer is 2～10mm.
Further, the thickness of said annular stack layer is 4～6mm.
The utility model is compared its advantage and is with prior art:
(1) body that overlaps in the blast-furnace tuyere of the utility model adopts steel to make, and steel strength is high on the one hand, has strengthened the support strength that overlaps in the blast-furnace tuyere, after receiving blast furnace furnace wall distortion extruding, is not easy distortion, has improved work-ing life.Can save the noble metal copper material more than 2/3 on the other hand, reduce material cost widely.(2) the preceding cap that overlaps in the blast-furnace tuyere of the utility model uses copper material, because copper material has higher thermal conductivity, cooling heat dissipation is effective, overlaps in order to avoid the interior high-temperature gas of blast furnace burns out in the blast-furnace tuyere that puts in the burner hearth.(3) in thick fine copper of sleeve rear end male cone (strobilus masculinus) built-up welding 2～10mm or low-alloy copper alloy material.Because this layer fine copper or low-alloy copper alloy material overlay cladding have low intensive performance, both guaranteed the stopping property of cover mating surface in tuyere big sleeve and the air port, protected the tuyere big sleeve in generation furnace life not to be worn again.
Description of drawings
Fig. 1 overlaps perspective view in the blast-furnace tuyere of the utility model;
Fig. 2 overlaps cross-sectional view in the blast-furnace tuyere of the utility model;
Among the figure: 1. body, 2. before cap, 3. overlay cladding, 4. water-in, 5. water outlet, 6. cooling chamber.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
As depicted in figs. 1 and 2; Overlap in a kind of blast-furnace tuyere; It comprises body 1 and preceding cap 2, and cap 2 is welded together to form the sleeve of the little rear end of front end auger barrel shape before steel body 1 and the copper material, and there is annular cooling chamber 6 telescopic inside; Sleeve rear end is provided with the water-in 4 and water outlet 5 that is communicated with cooling chamber 6, and the sleeve rear end male cone (strobilus masculinus) is the annular stack layer 3 of copper alloy material; The thickness of said annular stack layer is 4mm.
After should be noted that; Above content is only in order to explain the technical scheme of the utility model; But not to the restriction of the utility model protection domain; The simple modification that those of ordinary skill in the art carries out the technical scheme of the utility model perhaps is equal to replacement, does not all break away from the essence and the scope of the utility model technical scheme.
Claims (3)
1. overlap in a blast-furnace tuyere; It comprises body (1) and preceding cap (2); It is characterized in that: cap (2) is welded together to form the sleeve of the little rear end of front end auger barrel shape before steel body (1) and the copper material; There is annular cooling chamber (6) telescopic inside, and sleeve rear end is provided with water-in (4) and the water outlet (5) that is communicated with cooling chamber, and the sleeve rear end male cone (strobilus masculinus) is the annular stack layer (3) of fine copper or low-alloy copper alloy material.
2. overlap in the blast-furnace tuyere according to claim 1, it is characterized in that: the thickness of said annular stack layer (3) is 2～10mm.
