Description
Technical field
The invention belongs to blast furnace to cool down equipment technical field, more particularly to a kind of replaceable blast furnace cooling of high-strength wearable eddy flow
Column and its application.
Background technology
Blast furnace crucibe, furnace bosh, bosh, shaft cooling system are the important equipments of blast fumance, and blast furnace cooling stave is blast furnace
The important water cooling part of liner, installed in positions such as the shaft of blast furnace, furnace bosh, bosh, cupola wells, not only bears high temperature, also subject to stove
The abrasion of material, the erosion of slag and Gas Flow wash away, it is necessary to possess good calorific intensity, heat shock resistance, anti-rapid heat cycle
Etc. comprehensive performance.Cooling wall can effectively prevent furnace shell be heated and burn it is red, after blast furnace lining brick is ablated mainly by slag crust protect
Cooling wall in itself, and maintains the safety in production of blast furnace.
Large blast furnace cupola well, stack stave are large number of, big in restoration of lower stack, furnace bosh and bosh region heat flow rate per unit area,
Temperature fluctuation is acutely also big with material thermal stress, and often there is a situation where breakage, cooling wall water for the cooling wall system in this region
Intensity of cooling can substantially reduce after pipe breakage, so as to cause cooling wall wall body temperature to raise, producer skin is rubescent very when serious
To the accident of burn-through, significant impact is caused to safety in production.
There are poling and installation micro cooler currently for cooling wall breakage country primary solutions, for cooling wall water
The damaged larger miniature cooling wall that can only select to install of pipe postpones the service life, so as to keep blast furnace normally to produce.But current is micro-
Type cooler designing scheme has limitation, and such as miniature red copper cooler is since quality is softer, the not high easily mill leakage of intensity after being heated
And situation about fractureing is produced, and do not allow quick detachable, therefore also exist after cooler installation at present can not online dismounting and change
The shortcomings that.
Through retrieval, Chinese patent, application number：201520922539.2 date of publication：2016.05.11 disclose a kind of height
Stove cooling wall functional rehabilitation cooling column, is made of cylinder, antifriction alloy outer lining, water cooling tube and reinforcing rib；In cylinder or ellipse
Cylindricality cartridge outer surface is coated with one layer of antifriction alloy outer lining, and 1~4 reinforcing rib and at least 2 are equidistantly embedded with cylinder
" u "-shaped water cooling tube, is connected with cooling medium in water cooling tube.The utility model can continue to it after blast furnace cooling wall breakage
Local cooling function.But the utility model protects cooling column with one layer of antifriction alloy outer lining of spraying, is only applicable to part blast furnace
Cooling wall, when for the shaft of blast furnace, furnace bosh, bosh, cupola well when position, it is easy to by the abrasion of furnace charge, the erosion of slag
Fall with the erosion damage of Gas Flow, and, it is not easy to dismantle.
The content of the invention
1. technical problems to be solved by the inivention
For the miniature red copper cooler intensity in blast furnace cooling stave existing in the prior art is not high, service life is short,
The problem of quick detachable is not allowed, the present invention provides a kind of replaceable cooling column of blast furnace of high-strength wearable eddy flow and its application.It passes through
Wear-resisting red copper set mantle cavity is inserted into pipe is entered, the wear-resisting red copper set softer to quality plays strong supporting role, improve resistance to
The intensity of red copper set is ground, and the inner-outer circulation of cooling water is realized by helicla flute, it is uniform to realize miniature red copper cooler cooling
And intensity of cooling is high, the purpose of long lifespan, moreover, easily disassembled.
2. technical solution
To reach above-mentioned purpose, technical solution provided by the invention is：
A kind of replaceable cooling column of blast furnace of high-strength wearable eddy flow, including water inlet pipe, water outlet casing and wear-resisting red copper set, it is described
In the colling end insertion blast furnace cooling stave of wear-resisting red copper set, inner wall is provided with the helicla flute of outward turning；The water outlet casing takes the shape of the letter U sleeve
Shape, right end are provided with concentric holes, and left end is fixedly connected with the tail end that wear-resisting red copper covers, and side wall is provided with water outlet connection outlet pipe；Institute
The insertion end for stating water inlet pipe is inserted into the mantle cavity of wear-resisting red copper set through concentric holes, and covers and be in close contact with wear-resisting red copper, to wear-resisting
Red copper covers to form strong inside support, and outer wall and helicla flute form the water channel of circulation, and tail end is exposed at outside concentric holes and connects water source,
Cooling water can pass straight through to the end that wear-resisting red copper covers 3 mantle cavities by outlet pipe, then the cooling water of circulation is formed by helicla flute
After stream, outside the outlet pipe fairlead that current are passed through water outlet casing by the helicla flute of outward turning, the circulating cooling of cooling water, water inlet are completed
Pipe and purple steel bushing are worked in coordination, and play the effect of synergistic effect.
Preferably, the section of the helicla flute is square, and relative to other shapes, adds the film-cooled heat of cooling water,
Also intensity of cooling is increased；Current transition is left between the mantle cavity end of the insertion end termination of water inlet pipe and wear-resisting red copper set
