Abstract
The utility model provides a cooling column for recovering the function of a cooling wall of a blast furnace, which consists of a column body, a wear-resistant alloy outer lining, a water-cooling pipe and a reinforcing rib; the outer surface of the cylinder or the elliptic cylinder is coated with a layer of wear-resistant alloy outer lining, 1-4 reinforcing ribs and at least 2U-shaped water cooling pipes are embedded in the cylinder at equal intervals, and cooling media are introduced into the water cooling pipes. The utility model discloses can continue to maintain its local cooling function after blast furnace stave is damaged, make the life of damaged stave be not less than 2 years to can promote the blast furnace utilization coefficient more than 0.1, and effectively reduce blast furnace maintenance cost and ironmaking cost.
Description
Technical field
The utility model belongs to blast furnace cooling apparatus field, is specifically related to a kind of cooling stud for recovering refrigerating function after blast furnace cooling wall breakage.
Background technology
Along with blast furnace maximizes and the lifting of using degree, blast furnace cooling stave local damage phenomenon is aggravated, time serious, water-cooled tube can be caused to burn out, the even overall cooling stave of scaling loss and cooling plate, the serious production constraining blast furnace, and if body of heater cooling apparatus process after breakage accidentally, will potential safety hazard be brought, cause the dual decline of enterprise's production capacity and economic benefit.For this reason, many smelters have set up prolonging campaign team specially, select from cooling stave material, improve to methods for cooling, arrive cooling stave again to repair online etc. and carry out various research and trial, and define a series of technology differed from one another on this basis, as adopted online recovery technique, wearing hose technology outward, by recovering damaged cooling stave cooling duct, reach the object continuing to maintain cooling; Or adopt additional water cooler mode, by damaged cooling wall and the boring of outside furnace shell, water cooler is placed to damaged cooling stave position, again recovers the refrigerating function at this position with this, reach the object in the work-ing life extending cooling stave; Or adopt outer stove skin and cooling stave body strengthening cooling provision, force to fetch water by outer stove skin or cooling stave uses the mode of high-pressure cooling water instead, to maintain the continuation production of blast furnace.Undoubtedly, the application of the especially additional water cooler mode of above-mentioned measure, maintain refrigerating function for continuing after cooling wall breakage, the work-ing life extending body of heater has great importance.But also there is certain inherent defect, as the wear resistance of water cooler, poling is subject to the situation restriction of cooling wall breakage, and waste water resource etc., the expection of people is also not yet reached in result of use.
Summary of the invention
The utility model aims to provide one and is convenient to installation and removal, can continue to maintain its Local cooling function after blast furnace cooling wall breakage, thus extends cooling stave work-ing life, reduces the cooling stud of smelting cost.
For this reason, the technical solution that the utility model is taked is:
A kind of blast furnace cooling stave functional rehabilitation cooling stud, is made up of cylinder, wear resistant alloy outer lining, water cooling tube and stiffening web; Be coated with one deck wear resistant alloy outer lining at cylinder or elliptical cylinder-shape cartridge outer surface, be equidistantly embedded with 1 ~ 4 stiffening web and at least 2 " U " shape water cooling tubes in cylinder, in water cooling tube, be connected with heat-eliminating medium.
Described heat-eliminating medium is service water or soft water.
Described cylinder length is 200 ~ 400mm, and diameter is 60 ~ 150mm.
Described wear resistant alloy outer lining thickness is 0.5 ~ 5mm.
The beneficial effects of the utility model are:
The utility model after blast furnace cooling wall breakage, can continue to maintain its Local cooling function, makes be not less than 2 years the work-ing life of damaged cooling wall, thus can promote the capacity factor of a blast furnace more than 0.1, and effectively reduce maintaining blast furnace expense and ironmaking cost.
Accompanying drawing explanation
Fig. 1 is cooling stud outside view;
Fig. 2 is cooling stud sectional view.
In figure: wear resistant alloy outer lining 1, cylinder 2, water cooling tube 3, stiffening web 4.
