Abstract
A copper water pipe cooling wall for a the blast furnace is casting copper cooling water pipe into the cooling wall base and level, transverse or oblique copper strips are welded on the water pipe that faces the heat face. The cooling wall is using the copper water pipe to supersede the steel water pipe in the traditional cooling wall and copper strips are welded to enlarge the heat-conducting area, furthermore, the traditional steel water pipe cooling wall needs to coated on the outer layer to prevent carbon penetration, the performance of heat-conducting of the coating layer is weak and air gap exists in the outer surface of the water, which increase the heat resistance, but the copper water pipe cooling wall overcomes the shortcoming, the appetency between the copper and the carbon is little and the copper water pipe cooling wall does not need coating anti-carburizing material, which reduces the loss of the heat resistance substantially. The major function of the cooling wall is close to the pure copper cooling wall, while the cost is reduced about 1/4 and raises the using life span substantially.
Description
Affiliated technical field
The utility model relates to a kind of blast furnace copper water pipe cooling stave.
Background technology
Blast furnace body is made up of body skin, continuously arranged cooling stave and inner lining refractory.Previous blast furnace cooling stave is as mother metal with grey cast iron; the centre is cast into the steel water-cooled tube, and under the repeated stress effect that temperature variation causes, these grey cast irons as mother metal can occur fine crack very soon and enlarge gradually; can not effectively protect water pipe, cause and leak.Though the high-toughness ductile iron that the eighties occurs has had tangible change as mother metal, but still does not satisfy the requirement that increases the service life.In view of copper has good heat conduction, extensibility, particularly corrosion resistance nature, to have caused people and adopted copper cooling stave, and large development has all been arranged at home and abroad, reached more than 20 years its work-ing life.A fly in the ointment is that cost is too high, is 5-6 times of conventional magnesium iron cooling stave.Therefore, people's a kind of moderate cost, performance appearance that just waiting in expectation near the new type cooling stave of copper cooling stave.
Summary of the invention
The purpose of this utility model is to satisfy people's requirement, adopts easy means, has both changed the existing structure of conventional water hose cooling stave, reduces the cost of fine copper cooling stave again, and effectively improves cooling stave work-ing life, and therefore a kind of copper water pipe cooling stave is provided.
The technical solution of the utility model is as follows:
This copper water pipe cooling stave is to be cast into copper water-cooled tube in the cooling stave matrix, and is welded with copper bar facing on the water pipe of hot side.Institute's bit copper bar can be vertical, horizontal or oblique copper bar.
Copper water pipe can adopt pipe, oblate pipe or other steel tubing in different shapes.
Cooling stave matrix inner face is the light face, or drives dovetail-indent ramming refractory matter, or cold edge, heat edge and all standing refractory brick.
Cooling stave matrix adopting graphitic cast iron, heat-resistant low-chromium cast iron, spheroidal graphite cast iron or cast steel etc. are made.
The copper water pipe cooling stave is to replace the steel water pipe with copper water pipe in traditional cooling stave, and is welded with vertical, horizontal or oblique copper bar on copper pipe, to enlarge heat-conducting area.Moreover traditional steel water pipe cooling stave need be coated with masking paste at its water pipe skin for anti-carburizing, this dope layer poor thermal conductivity, and have air gap with the water pipe outside surface, cause thermal resistance to increase.The copper water pipe cooling stave has then overcome this shortcoming, and the avidity of copper and carbon is very little, need not to be coated with masking paste, significantly reduces the thermal resistance loss.This cooling stave major function is near the fine copper cooling stave, and cost has reduced about 1/4, and improve work-ing life greatly.

Fig. 2 is the utility model view in transverse section
Embodiment
Introduce embodiment of the present utility model below in conjunction with accompanying drawing:
This copper water pipe cooling stave is cast into copper pipe (or oblate pipe, other steel tubing in different shapes) water-cooled tube (2) in cooling stave matrix (1), go up and be welded with laterally (or vertical, oblique) copper bar (3) facing the copper water pipe of hot side (2).During casting with the special type of cooling make copper pipe (2) and the unlikely fusing of copper bar (3) and can with body material such as cast iron closely casting become one.
Cooling stave matrix (1) inner face can adopt the light face, or drives dovetail-indent ramming refractory matter, or cold edge, heat edge and all standing refractory brick.
Cooling stave matrix (1) can adopt graphitic cast iron, heat-resistant low-chromium cast iron, spheroidal graphite cast iron or cast steel etc. to make.
Claims (5)
1. a blast furnace copper water pipe cooling stave is characterized in that being cast into copper water-cooled tube in the cooling stave matrix, faces on the water pipe of hot side to be welded with copper bar.
2. copper water pipe cooling stave according to claim 1 is characterized in that facing on the water pipe of hot side and is welded with vertical, horizontal or oblique copper bar.
3. copper water pipe cooling stave according to claim 1 is characterized in that copper water pipe adopts pipe, oblate pipe or other special pipe.
4. copper water pipe cooling stave according to claim 1 is characterized in that cooling stave matrix inner face is the light face, or drives dovetail-indent ramming refractory matter, or cold edge, heat edge and all standing refractory brick.
5. copper water pipe cooling stave according to claim 1 is characterized in that cooling stave matrix adopting graphitic cast iron, heat-resistant low-chromium cast iron, spheroidal graphite cast iron or cast steel makes.
