Description

Blast furnace reinforcing frame posture copper cooling wall
Technical field
The utility model relates to blast furnace cooling equipment technical field, refers to a kind of blast furnace reinforcing frame posture copper cooling wall particularly.
Background technology
Cooling stave is one of major equipment on iron-smelting blast furnace.According to blast furnace different sites, cooling stave adopts different materials and structure.Wherein, in blast-furnace bosh, furnace bosh and restoration of lower stack region, because heat flow rate per unit area is high, adopt copper cooling wall more.Copper cooling wall is compared with cast-iron cooling wall, has thermal conductivity high, the advantage that comprehensive thermal resistance is low.At blast furnace opening after 2 ~ 3 years, copper cooling wall hot side edge brick corrodes totally, and copper cooling wall relies on the high capacity of heat transmission, can to condense one deck slag crust at its hot side, to realize the self-shield of cooling stave.But in actual production, due to blast furnace crude fuel conditional fluctuation, operating duty adjustment or other uncontrollable factor, coming off of slag crust is caused in capital, cooling stave surface is caused to be directly exposed in washing away of high-temperature coal air-flow, slag flowing molten iron or high-temperature molten material, and causing cooling stave surface temperature sharply to raise, cooling stave built-in thermal stress increases.Due to copper cooling wall, at high temperature tensile strength is lower, is only 200MPa when 300 DEG C, therefore it easily deforms under the effect of high-temperature hot stress.From blast furnace Investigation on damage, can there is buckling deformation in the copper cooling wall for many years of being on active service, and according to different mounting means, cooling stave centre can be that " arc " is outstanding to hot side or huyashi-chuuka (cold chinese-style noodles), and cooling stave edge can outwards expand and warpage.Although above-mentioned distortion directly can not cause breakage and the fracture of cooling stave body, but cooling stave top/bottom part and furnace shell generation relative displacement can be caused, water inlet pipe and water outlet pipe can be broken time serious, after the buckling deformation of cooling stave top/bottom part generation simultaneously, itself and neighbouring cooling stave can produce gap, easily scurry into high-temperature coal air-flow and slag iron, and then burn out the water inlet pipe and water outlet pipe of cooling stave, cooling stave is once cut off the water supply, its body high temperature stream wash away erosion under, to damage very soon, and cause blast furnace to be forced to shutdown maintenance, not only upset the production order of steel mill, also can increase enterprise operation burden.
In original cooling stave design, huyashi-chuuka (cold chinese-style noodles) adopts several tumbler pins to retrain, and because tumbler pin is some constraint, restriction ability is limited.Blast furnace Investigation on damage and hot test show, near tumbler pin, cooling stave distortion is less, but in the position away from tumbler pin, as cooling stave top bottom, still distortion is serious.
For the problems referred to above and deficiency, be necessary to improve existing copper cooling stave, alleviate the thermal distortion of wall body, extend its service life, reduce enterprise operation cost.
Summary of the invention
The purpose of this utility model is the deficiency overcoming the existence of above-mentioned prior art, and provide a kind of blast furnace reinforcing frame posture copper cooling wall, it effectively can alleviate the thermal distortion of copper cooling wall, extends the service life of cooling stave, reduces enterprise operation cost.
For achieving the above object, blast furnace reinforcing frame posture copper cooling wall designed by the utility model, comprise the copper cooling wall body that inside is embedded with cooling water pipeline, the wall of two ends up and down of described copper cooling wall body is respectively arranged with the many water inlet interfaces and water outlet mouthpiece be connected with its internal cooling waterpipe, its special character is: the huyashi-chuuka (cold chinese-style noodles) of described copper cooling wall body blast furnace burner hearth is dorsad provided with the steel plate support frame in grid structure, the grid structure of described steel plate support frame joint is provided with tumbler pin everywhere, the end of described tumbler pin is inserted and is fastened on the huyashi-chuuka (cold chinese-style noodles) of copper cooling wall body.
Further, described steel plate support frame is made up of peripheral rectangular shaped rim and two wash plates of staggered arrangement set within it and two lateral partitions, and described tumbler pin is separately positioned on the joint everywhere of two wash plates and two lateral partitions.
Further, be also provided with X-type dividing plate in the central rectangular grid that described two wash plates and two lateral partitions are formed, the point of crossing of described X-type dividing plate is also provided with tumbler pin.
Again further, described steel plate support frame fits into one by the huyashi-chuuka (cold chinese-style noodles) of welded construction and copper cooling wall body.
Also further, described steel plate support frame (4) adopts sectional dimension to be that the Q235 carbon element steel of h × b=100mm × 40mm are welded.
The beneficial effects of the utility model are: on the huyashi-chuuka (cold chinese-style noodles) of copper cooling wall body, arrange steel plate support frame, and joint is provided with tumbler pin everywhere in the grid structure of steel plate support frame, make cooling stave on the basis of original some constraint, add the line constraint of steel plate support frame, because armor plate strength is high, and steel plate support frame is line constraint to cooling stave, restriction ability is strong, therefore effectively can suppress the thermal distortion of cooling stave, avoid the damage of cooling stave, cooling stave is extended work-ing life, thus reduce blast furnace maintenance number of times in the generation furnace life, significantly save enterprise operation cost.
