Description
Technical field
The utility model relates to a kind of device of technical field of blast furnace process, specifically is a kind of blast furnace material distribution chute.
Background technology
Blast furnace material distribution chute is the apparatus for distributing that bell-less blast furnace is smelted mode, in modern blast furnace is smelted, its roof pressure maintains 0.15Mp substantially, different its furnace roof central points according to the former material in each ironworks and the mode of smelting push up the scope of temperature at 300-800 ℃, when conditions of blast furnace up time not, the scope that can make its furnace roof central point top temperature in a short time is at 900-1100 ℃; But the minority ironworks is by opening the blast furnace central point, pushing up warm long term maintenance at 900-1100 ℃ thereby the top temperature of raising central point makes in high strength smelting mode.It is the former material (iron ore, agglomerate, coke and lime flux etc.) that all smeltings of blast furnace need to be transported to high furnace interior smelt that distributor chute mainly acts on.Therefore, improving blast furnace material distribution chute mainly is that wear-resistant, high temperature resistant, shock-resistant, its housing will have higher non-deformability work-ing life
Find through retrieval prior art, the body of existing blast furnace material distribution chute mostly is semicircular arc or rectangle, the material feeding structure is divided into fish scale slabbing structure formation substantially, in forms such as surface of steel plate pile-up welding hard alloy formula, material abrasive construction formula, pottery, alloy combined types.The distributor chute of this spline structure is because wear liner, high temperature ageing and can't tolerate long-time impact and cause only maintain 8～10 months its work-ing life.
The utility model content
The utility model provides a kind of blast furnace material distribution chute at the prior art above shortcomings, has wear-resistant, high temperature resistant, shock-resistant long lifetime distributor chute, and design service life extends at least 12 months.
The utility model is achieved through the following technical solutions, the utility model comprises: housing, chute head body, zone of oxidation, abrasive plate, liner plate and thermofin, wherein: chute head body is arranged at an end of housing, zone of oxidation is positioned at the inner surface in the suspension ring hole of chute head body, some roads abrasive plate is positioned at enclosure interior and perpendicular to the axis of housing, liner plate is arranged on the abrasive plate and is perpendicular with abrasive plate, and thermofin is positioned at hull outside, directly contacts with gas fluid in blast furnace.
Described housing is that the cross section is semicircle or orthogonal column structure; Described thickness of oxide layer 0.1～0.8mm, this zone of oxidation is made for the burning material, makes the inboard in suspension ring hole of forehead body have abrasionproof, resistance to high temperature oxidation function; The inclination angle of described abrasive plate is 45 °～65 °, and the width of this abrasive plate is 150～250mm; It is 5～20 millimeters weld-deposited cladding that the surface of abrasive plate is provided with thickness.
Described liner plate is that the cross section is semicircle or orthogonal column structure, and this liner plate and housing are the similar figures structure, and the thickness of liner plate is 20～50mm, and this liner plate is made by crystalline stone materials; The thickness of described thermofin is 30～50mm.
The utility model uses the checking life-span to reach more than 12 months through reality, compared with prior art has the advantage of Wear-resistant, high-temperature resistant.
