Abstract
The utility model relates to a composite cooling wall. A cast copper working surface is used as one part of a wall body, and the other part of the wall body is a cast iron working surface. A copper cooling water tube is arranged in the composite wall body. The leading-out end of the copper cooling water tube of the cast iron working surface is sheathed with a steel tube sleeve, and a rib plate with fixedly embedded bricks is arranged on the cast copper working surface to form the composite cooling wall with double-layer cooling. The cooling wall has the characteristics of reasonable design and convenient installation. Moreover, each of the embedded bricks is thicker than a copper cooling wall with firmness. The brick supporting capacity of the utility model is stronger than that of the copper cooling wall, which is favorable for prolonging the service life of a blast furnace. The utility model can replace a presently universal cast iron cooling plate or the copper cooling wall when applied to a 255-4000 m< 3 > blast furnace.
Description
Technical field, the utility model relate to a kind of cooling or the cooling of furnace charge in stove of stove, particularly a kind of compound cooling stave.
Background technology when blast furnace uses cast-iron cooling wall at present, because the cast-iron cooling wall life-span is short, therefore, also influences the generation life-span of blast furnace.For a generation that makes blast furnace reaches more than 10 years work-ing life, must carry out annual overhaul change damaged cooling apparatus (cast-iron cooling wall) or carried out in 3～4 years in repair, change damaged cooling apparatus and also build refractory materials by laying bricks or stones.Chinese large-sized blast furnace (1500m in recent years
3More than) adopt copper cooling wall at bosh to restoration of lower stack (damaged position easily takes place cooling stave).Because copper cooling wall costs an arm and a leg (6.0～6.5 ten thousand yuan/ton), investment increases during newly-built or overhaul blast furnace, thereby pig iron cost is improved.The utility model has designed a kind of about 3.0 ten thousand yuan/ton of price of compound cooling stave, and the edge brick is thicker and firm than copper cooling wall, and the holder brick is can the force rate copper cooling wall strong, more helps prolonging the work-ing life of blast furnace.
Summary of the invention, the purpose of this utility model provide a kind of compound cooling stave.
The technical scheme that its technical problem that solves the utility model adopts is: compound cooling stave is to adopt rectangle or quadrate wall body, the some of wall body is the cast copper working face, some is cast iron or cast steel working face, in compound wall body, has 3-6 row copper water-cooled tube, be with steel pipe socket at cast iron or cast steel working face copper water-cooled tube leading-out end, on the cast copper working face, have the gusset of fixing edge brick.Constitute individual layer or the compound cooling stave of double-deck refrigerative.
The beneficial effects of the utility model are, and are reasonable in design, easy for installation, and the edge brick is thicker and firm than copper cooling wall, and the holder brick is can the force rate copper cooling wall strong, more help prolonging the work-ing life of blast furnace.Be applied in 255～4000m
3Blast furnace on, alternative general cast-iron cooling wall or copper cooling wall at present.
