Abstract
The utility model relates to a blast furnace stock distributing downspouting belonging to blast furnace stock distributing device, in particular relating to a fitting component for large and medium-size blast furnace stock distributing. The utility model resolves the problems as serious deformation of scaleboard under high temperature status and reject of ore dropping area due to the holes formed, which is mainly composed of a slot body (1), scaleboards (2) evenly distributed on internal surface of the slot body (1) and bolts (3) connecting the slot body (1) and the scaleboards (2) into a whole. The utility model is characterized in that: an anti-impact and wear layer (4) is fixed at the ore dropping place of the scaleboard (2), which is connected with the slot body (1) and the scaleboards (2) into a whole through the bolts (3). The utility model is characterized in anti-impact and wear, impossible of seriously deforming under high temperature and generating holes at the ore dropping area, which enhances the service life from the original 8 months to 11 to 14 months.
Description
One, affiliated technical field
The utility model belongs to bf fabric device, relates in particular to the device feature of big-and-middle-sized blast furnace material distribution.
Two, background technology
Before the utility model, the device of the big-and-middle-sized blast furnace material distribution in the metallurgy industry, though abrasion-proof backing block is housed in chute, but its liner plate because: a kind of welding wire built-up welding that is to use forms, and its block form is whole arc sectional type, and its deficiency is that in use its liner plate is out of shape under the condition of high temperature seriously, influence the normal cloth of blast furnace, especially in the use later stage of chute, ore shoots down the district and also can form hole and it is scrapped, thereby makes the blast furnace can't works better; Another kind is that liner plate adopts alloy casting to form, though it has solved the serious problem of distortion under the condition of high temperature, the problem that forms hole that is hit that ore shoots down the district is not resolved yet, and be 8 months work-ing life.
Three, technology contents
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of wear-resistant, shock proof novel blast-furnace distributor chute is provided.
Its technical scheme:
Mainly by cell body, be uniformly distributed in the liner plate of cell body internal surface, novel blast-furnace distributor chute that bolt that cell body and liner plate are connected as a single entity is formed, for making wear-resistant, the shock resistance of its distributor chute, be fixed with impact-resistant abrasion-proof at the ore place of shooting down of liner plate and decrease layer, impact-resistant abrasion-proof decreases layer and is connected as a single entity by bolt and cell body, liner plate.
This novel blast-furnace distributor chute shock resistance, wear-resistant can not produce the serious phenomenon of distortion under the condition of high temperature, bring up to 11～14 months work-ing life, thereby has reduced the number of times that blast furnace stops production and overhauls, and has improved the high efficiency of furnace, has reduced production cost.
Principle of work is identical with the principle of former chute.

Five, technology implementation scheme
Details are as follows below in conjunction with accompanying drawing:
Mainly by cell body (1), be uniformly distributed in the liner plate (2) of cell body (1) internal surface, novel blast-furnace distributor chute that bolt (3) that cell body (1) and liner plate (2) are connected as a single entity is formed, for making wear-resistant, the shock resistance of its distributor chute, partly stud with impact-resistant abrasion-proof at the ore place of shooting down of liner plate (2) and decrease layer (4), and be connected as a single entity by bolt (3) and cell body (1), liner plate (2).
Principle of work is identical with the principle of former chute.
Claims (1)
1, novel blast-furnace distributor chute, mainly by cell body (1), be uniformly distributed in the liner plate (2) of cell body (1) internal surface, bolt (3) that cell body (1) and liner plate (2) are connected as a single entity forms, it is characterized in that being fixed with impact-resistant abrasion-proof at the ore place of shooting down of liner plate (2) decreases layer (4), impact-resistant abrasion-proof decreases layer (4) and is connected as a single entity by bolt (3) and cell body (1), liner plate (2).
