Abstract
The invention relates to a blast furnace distributing device, particularly a production technology of a blast furnace distributing bell-less distributing chute. The blast furnace distributing chute comprises a semicircular groove template, and a first liner plate, a second liner plate, and a third liner plate are successively arranged in the inner surface of the template longitudinally, composite heatproof wear resistant steel blocks are respectively fused on the first liner plate and the third liner plate, heatproof wear resistant alloy blocks are fused on the second liner plate, and left and right ends of the first, second and third liner plate are fixed on the template through bolts. According to the invention, a few alloy blocks are used in the whole distributing chute, so that the cost is greatly reduced; in addition, the shocked second liner plate is fixed on the template through bolts, when the alloy blocks wear away, all it requires are taking down the second liner plate and replacing with a new liner plate with alloy blocks without changing the whole distributing chute, so that the a lot of cost is reduced.
Description
Technical field
The present invention relates to a kind of bf fabric device, be specifically related to a kind of manufacturing technology field of blast furnace bell-less distributor chute.
Background technology
Along with the generally use of blast furnace bell-less furnace roof, the life-span of distributor chute becomes the important factor that can bf fabric device normally move, and will prolong the work-ing life of distributor chute, and key is to strengthen the wear resistance of liner plate, reduces the wearing and tearing of mineral aggregate to liner plate.Prior art is employed in build-up wear-resistant material on the liner plate or connects the mode of wear-resistant block with bolt, improves the abrasion resistance properties of liner plate.Aforesaid method has improved the wear resisting property of liner plate to a certain extent relatively, but this following problem of corresponding existence: build-up wear-resistant material on liner plate is owing to receive process technology limit, and the hardness of high-abrasive material is relatively low, and the wear resisting property of liner plate is difficult to increase substantially; With the liner plate of bolt connection wear-resistant block, the space between wear-resistant block and the liner plate is protection not, and tiny this space of mineral aggregate long term wear makes liner plate worn out, and wear-resistant block comes off, and causes liner plate to lose efficacy, and is difficult to prolong significantly the liner plate purpose in work-ing life equally.
In addition, find that mineral aggregate only is the part wearing and tearing to the wearing and tearing of distributor chute through long-term observation; Major part is the middle part serious wear of distributor chute, the distributor chute of existing manufacturer production, its build-up wear-resistant alloy material or connect wear-resisting alloy block with bolt on whole liner plate; Wear resistant alloy material costs an arm and a leg, but above-mentioned distributor chute is after middle part wearing and tearing, must integral replacing; Wasted a large amount of alloy materials like this, promptly piece of cloth material chute can slattern most money.
Summary of the invention
Cause waste of material, problem that cost is high in order to solve existing distributor chute, the present invention provides a kind of distributor chute.
The present invention includes semicircle flute profile template; Vertically set gradually first liner plate, second liner plate, the 3rd liner plate at said template internal surface; The wear-resisting bloom of difference fusion composite heat resistance on said first liner plate and the 3rd liner plate; Fusion composite heat resistance wear-resisting alloy block on said second liner plate, the right ends of said first, second, third liner plate is respectively through being bolted on the template.
The position of second liner plate of the present invention is the key position of blast furnace blanking, and the first and the 3rd liner plate place can not receive the impact of mineral aggregate basically, so on second liner plate, use the alloy block of antiwear heat resisting; On the first and the 3rd liner plate, use the bloom of common antiwear heat resisting; Because of common wear resisting steel cost is lower, and the price of alloy block is than higher, in sum; Only used a spot of alloy block on the monoblock distributor chute, it greatly reduces cost; In addition, second liner plate that is hit is fixed by bolts on the template, when alloy block weares and teares in a large number, only need take off second liner plate, changes the new liner plate that has alloy block and gets final product, and need not to change the monoblock distributor chute, has so also practiced thrift a large amount of costs.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention;
Among the figure, 1, template, 2, first liner plate, 3, second liner plate, the 4, the 3rd liner plate, 5, bloom, 6, alloy block, 7, bolt.
Embodiment
As shown in Figure 1; This distributor chute comprises semicircle flute profile template 1; Vertically set gradually first liner plate 2, second liner plate 3, the 3rd liner plate 4 at template 1 internal surface; The wear-resisting bloom 5 of difference fusion composite heat resistance on first liner plate 2 and the 3rd liner plate 3, the right ends of fusion composite heat resistance wear-resisting alloy block 6, first, second, third liner plates 2,3,4 is fixed on the template 1 through bolt 7 respectively on second liner plate 3.
