Description
Technical field
The utility model relates to non-ferrous metal metallurgy cooling device, definitely says and relates to the coldplate of cast-ining steel pipe in the copper matrix that a kind of mineral hot furnace uses.
Background technology
Mineral hot furnace is mainly to utilize arc discharge to produce amount of heat, the accordingly Thermal Equipment of melting ore and metal.In recent ten years, mine heat furnace smelting technology develops rapidly both at home and abroad, efficient, the long-lived important directions that has become mine heat furnace smelting technical development.Due to mineral hot furnace concentration of energy in arc discharge process, arc region temperature is more than 3000 DEG C, and mineral hot furnace wall body stands high temperature erosion for a long time.In order to reduce the surface temperature of ore deposit hot wall body, extend mineral hot furnace service life, conventionally need to be at the peripheral coldplate of installing of mineral hot furnace.
Mineral hot furnace coldplate is for the body of heater of mineral hot furnace provides cooling equipment, can protect mineral hot furnace to avoid the erosion of high temperature fluid in body of heater, extends the mineral hot furnace life-span, ensures its safety and stability production.Once cooling device goes wrong, mineral hot furnace is stop production to overhaul comprehensively, will bring heavy economic losses.So the life-span of coldplate and performance determine the life-span of mineral hot furnace, be mineral hot furnace longevity, efficient important guarantee.
The coldplate material that the outer mineral hot furnace industry of Present Domestic generally adopts is mainly corrosion resistant plate, general steel plate, by by mode curling, assembled to corrosion resistant plate, general steel plate, welding, form the cooling-water duct of many sealings, when cooling water is through in the process of this passage, heat is constantly taken out of outside body of heater, reduce accordingly the temperature of mineral hot furnace wall body, make mineral hot furnace avoid high temperature erosion.This traditional design has the following disadvantages: compared with the heat conductivility of (1) and copper (the normal temperature thermal conductivity factor of copper is about 400Wm-1K-1), the heat conductivility poor (the normal temperature thermal conductivity factor of common 20# carbon steel is about 40Wm-1K-1) of ordinary carbon steel, stainless heat conductivility takes second place (304 conventional stainless normal temperature thermal conductivity factors are about 20Wm-1K-1), make to provide the cooling water of larger flow and pressure to coldplate, to ensure the cooling capacity of coldplate.(2) there is cooling water dead angle in the turning of traditional cooling-water duct, causes cooling blind spot more, easily causes hot-spot, cause Local cooling water boiling in cooling duct, increase the weight of the Precipitation of foreign ion in cooling water, increase cooling water is taken away the resistance of heat, reduces cooling effect.(3) because the weld seam relating to is more, easily there is drainage, the normal use that endangers coldplate on the one hand, on the other hand, penetrate in the high temperature fluent metal in mineral hot furnace once cooling water, may cause confined explosion in mineral hot furnace, will cause great potential safety hazard.
Have in the industry the technical scheme that adopts fine copper to cast the coldplate forming, the matrix of coldplate and cooling water pipe all adopt metallic copper, and this scheme exists following not enough: (1) cooling water pipe also adopts metallic copper, has further improved material cost; (2) easily there is burn through and distortion in copper cooling water pipe in casting process, and production process yield rate is low; (3) copper cooling water pipe is in actual use because intensity is low, in expanded by heating repeatedly, deformation process, easily damaged, and then leakage accident occurs, and causes potential safety hazard.
In addition, also exist in the industry and adopt the coldplate of rolling fine copper as matrix, the technical scheme of then processing cooling duct by the mode of boring.Also there is defect in this scheme: (1) casts the copper matrix forming need to pass through rolling, has further improved production cost.(2) in boring procedure, often there is the problem in inclined to one side hole, cause cooling duct to misalign, increase cooling water input resistance, cause cooling water transportation problem.(3) process cooling duct in the mode of holing, can not be processed with the passage at turning, in the corner of cooling duct, still need to adopt the mode of welding.Easily there is aforesaid leakage problems in commissure, has potential safety hazard.
Summary of the invention
The problem existing in order to overcome prior art, the purpose of this utility model is to provide the novel coldplate of cast-ining steel pipe in the special copper matrix of a kind of mineral hot furnace, oxygen-free copper is coldplate and the rolled steel cooling water pipe integral casting forming of matrix, to replace traditional ordinary carbon steel, stainless steel or fine copper coldplate.
The technical scheme that the utility model is taked is:
The coldplate of cast-ining steel pipe in the copper matrix that a kind of mineral hot furnace is used, comprise oxygen-free copper cooling plate base body processed and steel cooling water pipe, its technical characterstic is, described cooling plate base body and cooling water pipe are integral casting forming, and cooling water pipe is located in cooling plate base body and is closely fused with cooling plate base body.
Further, described cooling plate base body takes the shape of the letter U, the water inlet end of cooling tube and water side respectively from U-shaped cooling plate base body coldplate two ends stretch out.
Again further, described cooling water pipe is many and is set up in parallel.
Take after above technical scheme, the beneficial effects of the utility model are:
(1) compared with ordinary carbon steel, stainless steel coldplate, employing oxygen-free copper matrix coldplate has promoted the overall heat conduction cooling capacity of coldplate, has reduced the use amount of cooling water.
(2) because the fusing point of steel is higher than copper, compared with fine copper coldplate, the burn through and the low problem of yield rate that adopt steel cooling water pipe to avoid cooling water pipe to occur in casting process.
(3) compared with adopting ordinary carbon steel, stainless steel coldplate or rolling fine copper coldplate, cooling water pipe and the moulding of matrix one-step casting, avoided the deficiency such as dead angle, weld seam of welding and rolling, improved production efficiency, reduce production cost, reduced the cooling blind spot of coldplate simultaneously.
(4) adopt steel cooling water pipe, improved ability and the mechanical performance of the resistance to deformation of coldplate, extend the service life of coldplate.
To sum up, the utility model adopts the coldplate of cast-ining steel pipe in copper matrix to improve the combination property of coldplate, the production technology of mineral hot furnace coldplate has been simplified in one-step casting moulding, has extended the coldplate life-span and then has extended the life-span of mineral hot furnace, saves production, the maintenance cost of mineral hot furnace; And cooling water pipe and cooling plate base body are combined closely, further improve coldplate cooling effect and mechanical performance.
