Abstract
The present invention discloses a cooling board of a blast furnace, which is composed of a casing and a partition board for a water channel. The present invention is characterized in that the casing (1) is a copper flat cup body, the steel partition board (5) for a cooling water channel is installed in the casing (1), a steel flange (7) is connected together with the outer edge flange of the copper casing through connecting pieces (8), namely a boil and a nut, a washer (6) is sealed between the steel flange (7) and the outer edge flange of the copper casing, and holes (7-1, 7-2) for water to enter and egress are arranged on the surface of the flange (7). The present invention has the advantages of reduction of manufacturing cost and convenient installation and disassembly with a casing of a blast furnace.
Description
Technical field
Blast furnace cooling board of the present invention is a kind of blast furnace cooling apparatus, belongs to the ironmaking technology field.
Background technology
The blast furnace cooling apparatus mainly contains and inserts in the State of Blast Furnace, and furnace wall is carried out point type refrigerative cooling plate and covers the last furnace shell inboard, and furnace wall is carried out two kinds of patterns of face formula refrigerative cooling stave.For adapting to blast furnace longevity, the cooling apparatus that blast furnace uses is constantly updating.Copper cooling plate as one of main pattern of blast furnace cooling apparatus, develop into six present passages and eight passages from two passages and four-way, its thermal shock resistance can satisfy the requirement of blast furnace actually operating fully, prolong work-ing life greatly, it is with a wide range of applications as the blast furnace cooling apparatus.But the copper cooling plate of blast furnace use at present all is to adopt the cast-in-block method to produce, and all adopts expensive copper material inside and outside it, can be called the monoblock type copper cooling plate according to its manufacturing process.Along with increasing of copper cooling plate passage, internal partition quantity is also corresponding to be increased, and the also corresponding increase of copper material that dividing plate is required, so cost of equipment height are unfavorable for extensive popularization.
Summary of the invention
The objective of the invention is to disclose a kind of built-up type cooling plate, its cooling plate housing can be made of different materials with cooling-water duct dividing plate and outer end-plate, comes assembly by the form of mechanical assembly.Because the performance characteristics of cooling plate, heat-eliminating medium in the cooling plate mainly carries out heat exchange by the hot-fluid in its shell and the State of Blast Furnace, and the material of water channel dividing plate inner with it and outer end-plate relation is little, therefore, blast furnace cooling board can adopt different materials, come assembly by the form of mechanical assembly, thereby significantly reduce production costs, be convenient in more blast furnace, promote the use of.
Above-mentioned purpose is achieved in that it is that cooling plate is resolved into copper shell, outer end-plate, water channel dividing plate.Can be used as cold after the water channel dummy plate is good casts with housing.After finishing the said modules manufacturing respectively, assemble by web member.Wherein outer end-plate, water channel dividing plate can adopt steel plate to make.
The present invention compares with all-in-one-piece copper cooling plate, and its principal feature is: (1) the present invention made separately by each assembly, assembles then, and manufacture craft is simple, and processing charges is low.(2) water channel dividing plate of the present invention and flange adopt steel material, and with respect to the monoblock type copper cooling plate, displacement copper amount can reach more than 20%, with a 1350m who adopts the monoblock type copper cooling plate
3Blast furnace is an example, and the investment that the present invention can save cooling apparatus reaches more than 2,000,000 yuan.(3) the present invention is made separately by each assembly, and its workmanship can be observed in copper shell inside, and can reprocess, and assembling then can guarantee the inner workmanship of cooling plate, guarantees that current are unobstructed, stable.Therefore, this whole thermal shock resistance of the present invention can further improve, and the life-span is longer.
Description of drawings
Accompanying drawing 1: the top plan view of monoblock type copper cooling plate;
Accompanying drawing 2: the main pseudosection of cooling plate of the present invention;

Among the figure, part 1 is copper housing, and part 2 is copper water channel dividing plate, and part 3 is copper end face, and part 4 is a steel loop, the water channel dividing plate that part 5 is made for steel plate, and part 6 is a seal washer, and part 7 is a flange, and part 8 is bolt, nut, and part 9 is a dog screw, part 10 is the furnace shell short tube.
Embodiment
Below in conjunction with accompanying drawing further instruction in addition:
Be illustrated in figure 1 as the embodiment of present monoblock type copper cooling plate: the copper housing 1 of flat cup, copper water channel dividing plate 2 and copper end face 3 all adopt copper cast-in-block method to produce, welding one circle steel loop 4 on the end face 3 is then by steel loop 4 and 10 welding of furnace shell short tube.
Be depicted as the embodiment of cooling plate of the present invention as Fig. 2,3: the copper housing 1 of flat cup, its inside have been installed the water channel dividing plate 5 that adopts steel plate to make; Prosopyle 7-1 and posticum 7-2 have been opened on 7 of the flanges; Flange 7 is to link together by web member bolt, nut 8 with the outer rim flange of copper shell 1, has added seal washer 6 therebetween, and copper shell is played effect fixing and sealing; Flange adopts steel plate to make, the water channel dividing plate cast in housing component 1 or hot charging together.
Be illustrated in figure 4 as the outer rim flange connection of flange 7 and copper shell 1: flange 7 links together by dog screw 9 with the outer rim flange of copper shell 1, added seal washer 6 therebetween, when scene installation, dismounting web member bolt, nut 8 (installing with the furnace shell short tube again), can keep the fixing and sealing of housing 1 and flange 7, be unlikely to loosening dislocation.
Be illustrated in figure 5 as the embodiment of the present invention under the situation of two chambers eight passages: housing 1 is double-deck 1-1,1-2, has opened hole 7-3,7-4 for water-in and water-out on 7 of the flanges.When housing 1-1 goes wrong, can close its water inlet 7-3 hole, housing component 1-2 can replace housing 1-1 work, reduces the maintenance number of times, improves the blast-furnace production campaign.
Be one of mode of connection of implementing built-up type copper cooling plate of the present invention and last furnace shell as shown in Figure 6: housing 1 and flange 7 and furnace shell short tube 10 are connected together by bolt, nut 8, both solve the installation of cooling plate, solved the sealing problem of water coolant and blast furnace gas again.This mode mounts and dismounts all very convenient, need not get angry.
