Abstract
The utility model relates to a blast furnace cooling wall, particularly a nesting type blast furnace cooling wall. The utility model comprises an outer casket body of the cooling wall made up of a refractory product containing carbon, a cooling wall inner body which is sheathed in the inner cavity of the outer casket body of the cooling wall and is made up of ramming material containing carbon or silicon carbide ramming material, and a circulating cooling water pipe. The utility model has the advantages that the cooling efficiency is high; the capacity for resisting the high-temperature fracture of the melting molten iron and the chemical corrosion is high; the danger of an accidental burning through accident is eliminated; a firebrick lining of a furnace hearth can be thoroughly used; the construction investment is saved; the life time of the blast furnace can be prolonged; the superiority of the economic benefit of the enterprises can be raised. The utility model is suitable for modern blast furnaces with various volumes.
Description
(1), technical field: the utility model relates to a kind of blast furnace cooling stave, particularly a kind of sleeve type blast furnace cooling stave.
(2), background technology: at present, the furnace bottom of blast furnace, basque all adopt the cast-iron cooling wall of graphitic cast iron or other material iron casting, the steel circulating cooling water pipe that is cast into when the cast of cast iron high temperature is arranged in the cooling stave.Though, because the life-span of furnace bottom, brick lining is longer, this cooling wall breakage dangerous less is lower to the influence degree of blast furnace campaign.But the cast-iron cooling wall that uses with other position of blast furnace is the same, for preventing that the masking paste that carburizing is adopted from appearring in the steel circulating cooling water pipe when high temperature is cast, between circulating cooling water pipe and cast iron, produce the thermofin of high thermal resistance, reduced the cooling performance of cooling stave; And because cast iron can not be resisted the high temperature action of molten hot metal, in case the blast furnace lining breakage, when molten hot metal touched the cast-iron cooling wall surface, cast-iron cooling wall was melted immediately and causes the catastrophic failure that happens suddenly; Simultaneously, be that a kind of physics contacts fully between the amorphous refractory of in the cast-iron cooling wall slit, filling and the cast iron, molten hot metal is easy to break through this physical sealing and causes hearth breakout.For above-mentioned reasons, for prevent blast furnace produce in burst hearth breakout accident, when brick lining remnants that build by laying bricks or stones outside the cooling stave hot side～300mm, will carry out blast furnace overhaul.Like this, waste the residue bricking that originally can also continue to use, reduced blast furnace campaign, increased the production cost of enterprise, influenced economic benefit of enterprises.
(3), utility model content: the purpose of this utility model is, overcomes disadvantages of background technology, prolongs blast furnace campaign, improves the business economic benefit, designs the sleeve type blast furnace cooling stave.
The technical solution of the utility model is: a kind of sleeve type blast furnace cooling stave, contain the outer casket body of cooling stave, cooling stave endosome and circulating cooling water pipe.Suit is inlayed the cooling stave endosome that has circulating cooling water pipe in the casket intracoelomic cavity outside cooling stave.
The bonding surface of outer casket body of cooling stave and cooling stave endosome is a vertical plane, or be intilted inclined-plane, or be curved surface, perhaps be provided with section form papillary each other with a determining deviation, or trapezoidal shape, or the coupling vertical plane of rectangular-shaped strip groove or raised line or intilted inclined-plane.
Circulating cooling water pipe is U type pipe or hosepipe, and circulating cooling water pipe is embedded in the cooling stave endosome or outside cooling stave endosome and cooling stave between the bottom surface of casket intracoelomic cavity.
Huyashi-chuuka (cold chinese-style noodles) at cooling stave is provided with cooling stave installation web member.
The pipeline section that circulating cooling water pipe passed or entered cooling stave endosome huyashi-chuuka (cold chinese-style noodles) is provided with protective casing.
The outer casket body of cooling stave can use carbonaceous or semi-graphite or schungite-SiC matter or aluminium carbonaceous refractory product, cooling stave endosome can use the ramming mass of carbon containing or carborundum to make.
The utlity model has useful positively effect:
(1) the cooling stave endosome that is inlaid with circulating cooling water pipe closely contacts heat transfer efficiency height, good cooling results in casket body bottom surface with the outer casket body of cooling stave, cooling stave circulating cooling water pipe outward with the cooling stave that carbon containing refractory is made.
(2) outer casket body opposing molten iron high temperature action of the cooling stave made of carbon containing refractory and chemical erosion ability are strong, even when directly contacting molten hot metal, also can use the long period, have eliminated the danger of burst catastrophic failure.Like this, can make full use of the firebrick lining of building casket body heat face outside cooling stave by laying bricks or stones, prolong blast furnace campaign.
(3) proportion of sleeve type blast furnace cooling stave than cast-iron cooling wall little～80%, can reduce weight of equipment and construction investment significantly.
(4) the sleeve type blast furnace cooling stave can prolong blast furnace campaign, reduces construction investment, improves the business economic benefit.
