Technical field
The present invention relates to a kind of distributor chute device, especially relate to a kind of effective prolongation a kind of distributor chute in its work-ing life.
Background technology
In recent years, the development of the steel industry of China is swift and violent, and equipment also tends to maximize.In iron-making production, generally be not very long the work-ing life of the distribution device of iron-smelting blast furnace furnace roof, can be subjected to the work-ing life that externalitiess such as high temperature, gaseous corrosion, blanking impact, material wearing and tearing affect equipment itself in blast furnace.Usually be 6～8 months the mean life of large blast furnace distributor chute.This must be frequent the replacing distributor chute, it is consuming time not only to take a lot of work, waste material, but also directly have influence on the steady running and the pig iron production of blast furnace, even bring very big financial loss to iron and steel enterprise.
Summary of the invention
The present invention is directed to the problem that prior art exists, provide a kind of simple in structure, easy to process, improve wear-resistant, corrosion-resistant, the impact strength of chute, reduce running cost, effectively prolong its work-ing life, and be knockdown, a kind of distributor chute of maintenance, replacing more convenient and quicker.
The objective of the invention is to realize by the following technical solutions:
A kind of distributor chute, it comprises that a cross section is polygonal housing, it is: the internal surface of housing is provided with the bottom block suitable with its shape, longitudinally be provided with at least on this bottom block bottom surface one group by horizontal cuttage plate cuttage becomes with vertical cuttage plate " well " font cuttage board component; Wear resistant and impact resistant blanking port assembly, described bottom block two sides are provided with perpendicular muscle, described horizontal cuttage plate is provided with the identical pitch angle of direction with the bottom surface of bottom block, and is described " well " space of bottom surface, font cuttage board component middle part is provided with the shock resistance piece.
The upper end edge bottom block both sides of described perpendicular muscle are provided with edge-pressing strip.
Described pitch angle is any positive angle except that 0 °, 90 °, 180 °.
Described horizontal cuttage plate and vertical cuttage plate, and shock resistance piece, and on the working-surface of perpendicular muscle and bottom block, compound at least one deck high temperature resistance, lost material.
Described wear resistant and impact resistant blanking port assembly is close " well " laterally be provided with stiffening plate on the font cuttage board component one bottom face; Be respectively equipped with gusset at these stiffening plate two ends.
On the working-surface of described stiffening plate, compound at least one deck high temperature resistance, lost material.
Wear resistant and impact resistant blanking port one end of described housing is along being circumferentially with curved baffle.
The present invention compared with prior art, owing to adopted " well " structure formation of font cuttage board component, and take the measure of high temperature resistance anti-abrasive material structure combining, it is short work-ing life to have solved traditional distributor chute structure, be subjected to high temperature, gaseous corrosion, blanking impacts, the material wearing and tearing need the frequent distributor chute of changing, improved the wear-resisting of chute widely, corrosion-resistant, impact strength, particularly having improved the work-ing life and the convenient for maintaining of distributor chute effectively changes, reduced production cost, be applicable to blast furnace ironmaking, satisfy the service requirements under each operating mode of blast furnace, satisfy user's demand greatly, have remarkable economic efficiency and social benefit.

Among the figure: housing 1, perpendicular muscle 2, bottom block 3, horizontal cuttage plate 4, vertical cuttage plate 5, edge-pressing strip 6, shock resistance piece 7, " well " font cuttage board component 8, wear resistant and impact resistant blanking port assembly 9, stiffening plate 10, curved baffle 11.
Embodiment
Below in conjunction with specific embodiment the present invention is further elaborated, but protection scope of the present invention is not limited by specific embodiment, is as the criterion with claims.In addition, with under the prerequisite of technical solution of the present invention, any change or change that those of ordinary skills that the present invention did are realized easily all will fall within the claim scope of the present invention.
A kind of distributor chute of the present invention as shown in Figure 1, 2, 3, it comprises the polygon housing 1 of the cross section side's of being taper, the internal surface of its housing 1 is provided with the bottom block 3 suitable with its shape, longitudinally is provided with two and Ban on these bottom block 3 bottom surfaces and is become with vertical cuttage plate 5 cuttages by horizontal cuttage plate 4 " well " font cuttage board component 8; Wear resistant and impact resistant blanking port assembly 9, this wear resistant and impact resistant blanking port assembly 9 is close " well " laterally be provided with stiffening plate 10 on the font cuttage board component 8 one bottom faces, be respectively equipped with gusset at these stiffening plate 10 two ends, described bottom block 3 two sides are provided with perpendicular muscle 2, are provided with edge-pressing strip 6 in upper end edge bottom block 3 both sides of perpendicular muscle 2; Described horizontal cuttage plate 4 and the bottom surface of bottom block 3 be provided with direction identical less than 90 ° pitch angle, described " well " space of bottom surface, font cuttage board component 8 middle part is provided with shock resistance piece 7, and wear resistant and impact resistant blanking port 9 one ends of housing 1 of the present invention are along being circumferentially with curved baffle 11.In addition, described horizontal cuttage plate 4 and vertical cuttage plate 5, and shock resistance piece 7, and on the working-surface of perpendicular muscle 2 and bottom block 3 and stiffening plate 10, compound one deck high temperature resistance, lost material, described composite bed is by with repressed the forming of corresponding welding rod built-up welding.
The liner that feasible perpendicular muscle 2 of structure that employing the present invention is above-mentioned and bottom block 3 constitute in use, material can riddle after using for the first time " well " in the lattice of font cuttage board component 8, after use in, the wear form of material is the friction between material and the material, thereby reduces the gouging abrasion of material to the chute liner; Shock resistance piece 7 is born material in the use first time surging force is more serious, after use in impact forces can reduce gradually, therefore, be to save cost, area need not be too big.And in use, horizontal, vertical cuttage plate 4,5 is owing to be the direct plane of action of material, the wearing and tearing especially severe, so it all has high temperature resistance, lost material on working-surface outside.Especially upper surface, material directly impacts slip, and abrasion loss is far longer than all the other positions, and through the built-up welding abrasion-resistant material, improve work-ing life greatly.
