Abstract
The utility model relates to a blast furnace cooling wall, in particular to an assembled compound cooling wall. A circulating pipe is arranged in the cooling wall, and the cooling wall body consists of an inside and an outside cooling wall body connected by an impacting piece. The utility model can relatively well bring the capability characters of different metal materials into play, avoid the capability limitation of the prior cooling wall, and change part of the cooling wall body and save the project investment with advantages of a comprehensive capability and economic benefit.
Description
(1) technical field: the utility model relates to a kind of blast furnace cooling stave, particularly relates to a kind of compound cooling stave of formula of organizing.
(2) background technology: as everybody knows, blast furnace cooling stave is cast-iron cooling wall, cast steel cooling wall and copper cooling wall at present.The body of these cooling staves is cylinder iron, or cast steel, or the copper material is made, refrigeration cycle water pipe (road) is housed in body, the refrigeration cycle water pipe generally is to make by hot-cast to imbed in the cooling stave body, and the copper cooling wall that has adopts boring to form the refrigeration cycle aquaporin.
When adopting cast iron as body, temperature is very high during owing to the cast iron cast, the water pipe surface cementation in the cooling stave body, and liquefaction causes water pipe surface embrittlement, reduces the water pipe physical strength.At water pipe external coating masking paste, though reduce carburizing to a certain extent, there is not the surperficial liquefaction problem of fine solution, simultaneously, masking paste brings the harm that reduces heat transfer property again.
When adopting cast steel as the cooling stave body, though avoided carburizing, and the use properties of bulk material is superior to cast iron, and higher teeming temperature makes the water pipe surface occur liquefying to cause the danger of additional prestressing bigger.
When adopting the copper material to make whole cooling stave body, product cost is very expensive, and the resistance ratios of the cooling water circulation passage that boring forms on copper coin is bigger.
In addition, above-mentioned cooling stave also exists heat leak to damage to a certain degree, when needing to change cooling stave, must change the monoblock cooling stave, thereby has increased enterprise's spending, reduction economic benefit of enterprises.
CN2339950Y, all standing edge brick cooling stave is the improvement to traditional cooling stave, can prolong the cooling stave life-span to a certain extent.But its water-cooled tube remains hot and is cast into, and it remains one-piece construction, also have above-mentioned problem.
(3) utility model content, the purpose of this utility model is: in order to overcome the defective that existing cooling stave exists, prolong cooling stave work-ing life, develop combined cooling stave.
The technical scheme of utility model: a kind of combined cooling stave comprises the refrigeration cycle water pipe is housed in the cooling stave body that the cooling stave body is to be connected by fastener by inside and outside cooling wall body to combine.
In the mating surface of inside and outside cooling wall body, be provided with the groove that is complementary with the refrigeration cycle water pipe, or the refrigeration cycle water pipe is embedded in the internal cooling wall body, the water pipe that enters and pass from outer cooling wall body is equipped with protective sleeve.
The bonding surface of inside and outside cooling wall body is the mating surface that mates mutually.
Inside and outside cooling wall body can adopt same metal material, or different metallic substance, and can select metallic substance for use is cast iron, cast steel, copper material etc.
The beneficial effects of the utility model:
(1) combined cooling stave great advantage is: in same cooling stave, can use different metal material to make inside and outside cooling wall body respectively.The physicals of comprehensive performance different metal material.Adopt cast iron as outer cooling wall body, cast steel or copper material are as the internal cooling wall body.Perhaps, adopt cast steel as outer cooling wall body, the copper material is during as the internal cooling wall body, and cooling stave is to the cooling performance of blast furnace bricking and full cast steel or copper material identical entirely, but material cost descends significantly.
When (2) changing cooling stave, can only change the internal cooling wall body of damage, continue to use the outer cooling wall body that does not damage, reduce construction investment.
(3) having avoided hot is cast into water-cooled tube or forms the defective that cooling-water duct brought in copper coin boring.

(5) specific embodiment:
Embodiment one; referring to Fig. 1; 2; among the figure, 1 is cooling water circulation water pipe, and 2 are outside cooling wall body; 3 is inboard cooling wall body; inside and outside cooling wall body 3 tightens up and is fixed on the last furnace shell 5 by being connected fastener bolt 4 with 2, and refrigeration cycle water pipe 1 is installed in inside and outside cooling wall body 3 and the 2 interfacial matching slots, and enter pipe and the rising pipe place of circulating cooling water pipe 1 are set with and stretch out last furnace shell 5 protective sleeve 6 outward.
Embodiment two, and referring to Fig. 3, numbering is identical with embodiment one among the figure, represents same meaning, does not repeat.Have be, in the present embodiment, refrigeration cycle water pipe 1 is imbedded in the internal cooling wall body 3, water inlet pipe and rising pipe penetrate and pass from outer cooling wall body 2, and are set with protective sleeve 6, all the other are identical with embodiment one, do not repeat.
Claims (4)
1. a combined cooling stave comprises the refrigeration cycle water pipe is housed in the cooling stave body, it is characterized in that: the cooling stave body is to be connected by fastener by inside and outside cooling wall body to combine.
2. cooling stave according to claim 1; it is characterized in that: in the mating surface of inside and outside cooling wall body; be provided with the groove that is complementary with the refrigeration cycle water pipe, or the refrigeration cycle water pipe is embedded in the internal cooling wall body, the water pipe that enters and pass from outer cooling wall body is equipped with protective sleeve.
3. cooling stave according to claim 1 and 2 is characterized in that: the bonding surface of inside and outside cooling wall body is the mating surface that mates mutually.
4. cooling stave according to claim 1 and 2 is characterized in that: inside and outside cooling wall body can adopt same metal material, or different metallic substance, and can select metallic substance for use is cast iron, cast steel, copper material etc.
