Abstract
The utility model discloses a bell-less distributing chute of a blast furnace, which comprises a chute body, a lining plate arranged on the chute body and inclined transverse plates arranged on the lining plate. The upper portions of the inclined transverse plates are provided with abrasion-resistant layers made of abrasion-resistant ceramics or hard alloys. The bell-less distributing chute of the blast furnace utilizes the abrasion-resistant ceramics or the hard alloys to strengthen the upper portions of the inclined transverse plates and enables the inclined transverse plates to incline at 30 degrees to 60 degrees. Therefore, when the inclined transverse plates are in use, materials can remain between the inclined transverse plates and abrade the upper portions of the inclined transverse plates. The abrasion-resistant ceramics or the hard alloys arranged on the upper portions of the inclined transverse plates can greatly improve performance of abrasion resistance, corrosion resistance and impact resistance of the chute.
Description
Technical field
The utility model relates to the technical field of smelting equipment, is specifically related to a kind of blast furnace bell-less distributor chute.
Background technology
Development along with ironmaking technology; Existing domestic iron and steel enterprises generally adopts no bell furnace roof equipment when producing the pig iron, distributor is the nucleus equipment unit of no bell furnace roof equipment, drives chute through changing the uniform distribution that angle and speed realize furnace charge when blast furnace needs the transmission rig of when filling with substance distributor; Satisfy the requirement of iron-smelting process; Chute will bear the impact of materials such as ore, coke for a long time, need after the wearing and tearing in time to change, and blast furnace generally adopts the HTHP operation now; Iron-smelting blast furnace will pass through that decompression is diffused etc. process could be changed when changing chute, so is directly connected to the efficient and the cost of Iron and Steel Production the work-ing life of chute.
The top of distribution chute working position in blast furnace chamber, this place's temperature normal temps are 200 ℃-250 ℃, and working temperature can reach 900 ℃ when unusual; Work under bad environment, furnace charge are regularly dashed to fall and are caused the wearing and tearing aggravation on the chute liner plate, and present domestic chute was generally 6-10 month work-ing life; The chute lining plate structure is welded construction and cast form basically, and welded construction is through the surface overlaying wimet, and is simple in structure; Life-span is short partially; Cast structure generally adopts high-chromium alloy, and thermal treatment and technical requirements are very strict, and indexs such as its wear resistance, intensity, toughness can't reach external advanced level all the time.
The utility model content
The technical problem that the utility model will solve provides a kind of wear-resisting, lower-cost blast furnace bell-less distributor chute.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of blast furnace bell-less distributor chute comprises the chute body, is arranged on the liner plate on the chute body and is arranged on the oblique transverse slat on the liner plate that the top of said oblique transverse slat is provided with the wearing layer of wear-resistant ceramic or wimet.
The angle of inclination of said oblique transverse slat is 30 ~ 60 °.
Said wearing layer is L-shaped, and the wearing layer of said " L " shape is fixed on the upper end of the top end face and a sidewall of said oblique transverse slat.
Said wearing layer is fixed on the top end face of oblique transverse slat and/or the upper end of two side in the form of sheets.
Said wearing layer is fixed on the top end face of oblique transverse slat in the form of sheets, and the upper end of one or two sidewall of said oblique transverse slat is provided with overlay cladding.
Said wearing layer is " U " shape, and the wearing layer of said " U " shape is stuck in the upper end of said oblique transverse slat top end face and two side.
The beneficial effect that adopts technique scheme to produce is: 1) the utility model adopts wimet or wear-resistant ceramic to strengthen the top of oblique transverse slat; And oblique transverse slat is tilted 30 ~ 60 °; Make and in use leave material between the oblique transverse slat; Only the wear and tear top of oblique transverse slat of material, wear-resisting, corrosion-resistant, the shock-resistant ability that wear-resistant ceramic that tiltedly is provided with on the transverse slat or wimet can significantly improve chute; 2) be provided with plate crosswise after strengthening, reduced the built-up welding area, reduced the production cost of chute, and prolonged the work-ing life of chute, have remarkable economic efficiency and social benefit.
