Abstract
The utility model discloses a blast furnace distribution chute with a long service life. The blast furnace distribution chute comprises a chute body and an antiwear lining plate; the chute body is provided with a distribution zone and a storage zone; the distribution zone is arranged on the front end of the chute body; the storage zone is arranged on the rear end of the chute body; the antiwear lining plate is arranged on the bottoms and the inner walls of both the distribution zone and the storage zone. The impact wear of the blast furnace distribution chute is reduced, the safe operation is guaranteed, the service life is prolonged, and the maintenance cost is lowered.
Description
Technical field
The utility model relates to the blast furnace material distribution equipment technical field, particularly the Long Campaign Blast Furnace distributor chute.
Background technology
Distributor chute is the apparatus for distributing of blast furnace key, and cost is relatively more expensive.The blast furnace material distribution chute work under bad environment need be born repeatedly washing away of ore, coke in the production for a long time, and how to prolong its life-span is a very important problem always.Can the life-span of chute not only be related to the blast furnace maintenance cycle, also be related to blast furnace simultaneously and realize cloth steady in a long-term.Leak if there is chute matrix mill, meeting havoc smooth operation of furnace loses often very large.At present, the common practice that prolongs the chute life-span is the Wimet steel plate at the inboard build-up wear-resistant of chute, to increase the erosion resistibility of chute.In daily industrial production, the life-span of chute is decided by the wear pattern of the inboard discharging point of chute.Discharging point is the fastest zones of chute wearing and tearing, also is the bottleneck that prolongs the chute life-span.Along with the raising of blast furnace maximization and combustion intensity, the gouging abrasion load that the chute discharging point bears significantly promotes, and in order to guarantee the chute life-span, can only increase the alloy wear-resisting plate thickness, and the manufacture difficulty of chute and cost also raise more.
The utility model content
Technical problem to be solved in the utility model provides a kind of Long Campaign Blast Furnace distributor chute that can improve the blast furnace material distribution chute life-span and reduce production costs
For solving the problems of the technologies described above, the utility model provides a kind of Long Campaign Blast Furnace distributor chute, comprising: the chute body and the abrasion-resistant lining plate that are provided with cloth district and storing area;
Described cloth district is arranged on the front end of chute body, and described storing area is arranged on the rear end of chute body;
Described abrasion-resistant lining plate is arranged on the bottom and inwall of cloth district and storing area.
Further, the length in described cloth district is the 70%-80% of chute body length, and the length of described storing area is the 20%-30% of chute body length.
Further, the degree of depth is lower than bottom, the described cloth district degree of depth bottom the described storing area.
Further, the degree of depth is 50mm-60mm bottom the described storing area.
Further, described storing area bottom and bottom, cloth district be arranged in parallel.
Further, the side in described cloth district and the bottom vertical of storing area.
The Long Campaign Blast Furnace distributor chute that the utility model provides has reduced the gouging abrasion that blast furnace chute bears, and has guaranteed the safe operation of blast furnace chute, has prolonged the chute life-span, has reduced maintenance cost.
Description of drawings
The Long Campaign Blast Furnace distributor chute structural representation that Fig. 1 provides for the utility model embodiment.
Embodiment
Referring to Fig. 1, a kind of Long Campaign Blast Furnace distributor chute that the utility model embodiment provides comprises chute body 1, storing area 2, cloth district 3, abrasion-resistant lining plate 4.Cloth district 3 is arranged on the front end of chute body 1, and storing area 2 is arranged on the rear end of chute body 1.The length in cloth district 3 is the 70%-80% of the length of chute body 1, and the length of storing area 2 is the 20%-30% of chute body 1 length.The bottom degree of depth of storing area 2 is 50mm-60mm, be positioned at central throat tube under, be used for the storage of raw materials.Abrasion-resistant lining plate 4 is installed on the bottom of storing area 2 and the inwall, and during blast furnace material distribution, storing area 2 is full of raw material, and the raw material that falls from the chute top will directly impact the raw material in the storing area 2, rather than directly impact abrasion-resistant lining plate 4.The storing area 2 bottom degree of depth are lower than the bottom degree of depth in cloth district 3.Storing area 2 bottoms and 3 bottoms, cloth district be arranged in parallel.The bottom vertical of the side in cloth district 3 and storing area 2.On 3 bottoms, cloth district and the inwall abrasion-resistant lining plate 4 is installed, the raw material of falling storing area 2 from the chute top joins blast furnace by cloth district 3.
Below by embodiment the utility model is further specified.
Chute body 1 is cast member, and chute body 1 is divided into two districts, and the rear portion is storing area 2, and length is 0.3 times of chute body 1, and storing area 2 degree of depth are 55mm.The front portion is cloth district 3, length is 0.70 times of chute body, the lateral vertical of 3 bottom surfaces, cloth district and storing area 2, storing area 2 is installed abrasion-resistant lining plate 4 on cloth district 3 and storing area 2 bottom surfaces and the inwall under the aditus laryngis of center, after storing area 2 stores full ore, coke, on raw material drops on raw material in the storing area 2 from the center aditus laryngis, directly impact the raw material in the storing area 2, no longer directly impact abrasion-resistant lining plate 4, then raw material joins blast furnace by cloth district 3.
The Long Campaign Blast Furnace distributor chute that the utility model provides has reduced the gouging abrasion that blast furnace chute bears, and has guaranteed the safe operation of blast furnace chute, has prolonged the chute life-span, has reduced maintenance cost.
It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to example the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
