Abstract
A blast furnace cooling wall, which belongs to an iron-making blast furnace part. The existing blast furnace cooling wall is formed by processing a single pure copper plate, is internally provided with a water cooling channel, is easy to deform and has high cost. The cooling wall of the blast furnace of the utility model is formed by welding double metal plates along the periphery, and is internally provided with a water cooling channel and a water inlet and a water outlet. The bimetallic plate may be a steel-copper combination or a cast iron-copper combination. The water cooling channels can be arranged on the joint surface of the double metal plates in a split mode, and the water cooling channels can also be arranged in the double metal plates respectively. Adopt the utility model discloses can make the intensity increase of blast furnace stave, thermal stability improves, makes the cooling water course design more reasonable, makes the stave bulk temperature even, has avoided the stave yielding problem that causes the furnace inner wall to damage in operating condition, and has reduced manufacturing cost.
Description
(1) technical field:
The present invention relates to the parts on a kind of blast furnace, specifically a kind of blast furnace cooling stave.
(2) background technology:
Between high stove outer covering and refractory brick inner bag one deck cooling stave is arranged, the blast furnace cooling stave of present domestic use is single-material, and rolling fine copper plate processes.In establish circulating water channel.When making water channel, generally speaking, become through hole by deep hole machining, after add and block welding and finish.The cooling stave that this fine copper is made belongs to austenite structure, working heat poor stability, non-deformability are poor under the high temperature fatigue working condition, and the layout of circulating water channel is subjected to the restriction of processing condition, recirculated water can not make cooling stave whole body temperature reach consistent with the heat exchange of cooling stave, and its thermograde has caused structural stress and produced distortion.Its result makes that the flue that is built into by refractory brick is stressed and damages.In addition, whole fine copper manufacturing cost is also high.
(3) summary of the invention:
The object of the present invention is to provide a kind of non-deformability strong, and the low again blast furnace cooling stave of cost.
The present invention is achieved in that
This blast furnace cooling stave is to be welded along periphery by two metal plates, and has cooling water channel ， And be provided with intake-outlet in cooling stave.
The two metal plates of this blast furnace cooling stave can be to be welded by steel plate and fine copper plate, also can be to be welded by cast iron plate and fine copper plate, for guaranteeing that two metal plates in conjunction with firm, can be provided with swallow tail and dovetail-indent mating surface on the two metal plates bonding surface.
The cooling-water duct of this blast furnace cooling stave can be arranged on the bonding surface of two metal plates, is to split built-up type, also can be provided with in two two metal plates respectively.
This blast furnace cooling stave needs the layer of metal process layer is set on the bonding surface of another metal sheet when the fine copper plate portion is a casting on another metal sheet the time, and this smithcraft layer can be the fine copper overlay cladding, also can be that tining layer or brush cross layer.
Adopt the present invention for the cooling water channel of cooling stave provides processing conditions easily, can make the more reasonable of cooling water channel design, guaranteed that the cooling stave bulk temperature is even, the distortion fault of having avoided the Yin Wendu inequality to cause.Because of having adopted the two metal plates structure, bulk strength increases, and has also improved thermostability and non-deformability, and has reduced manufacturing cost again.
(4) description of drawings:
The invention will be further described below in conjunction with accompanying drawing;
Accompanying drawing 1 is the front view of this blast furnace cooling stave cooling water channel when placing the two metal plates bonding surface;
Accompanying drawing 2 is this blast furnace cooling stave front views when two metal plates bonding surface one side is provided with process layer;
Accompanying drawing 3 is this blast furnace cooling stave Fig. 1,2 side-view;
Accompanying drawing 4 is this blast furnace cooling stave cooling water channel front views when placing two metal plates inner respectively;
Accompanying drawing 5 is side-views of this blast furnace cooling stave Fig. 4;
Accompanying drawing 6 is this blast furnace cooling stave front views when being respectively equipped with swallow tail, dovetail-indent on the two metal plates bonding surface;
Accompanying drawing 7 is sectional views of this blast furnace cooling stave Fig. 6.
(5) embodiment:
This blast furnace cooling stave is to be welded along periphery by two metal plates 1,2, and has cooling water channel 3 ， And be provided with intake-outlet 4,5 in cooling stave.
The two metal plates of this blast furnace cooling stave can be to be welded by steel plate and fine copper plate, also can be to be welded by cast iron plate and fine copper plate.Shown in Fig. 6,7, for guaranteeing that two metal plates in conjunction with firm, can be provided with swallow tail and dovetail-indent mating surface on the two metal plates bonding surface.
Shown in Fig. 1,4, the cooling-water duct 3 of this blast furnace cooling stave can be arranged on the bonding surface of two metal plates, is and splits built-up type, also can be provided with in two two metal plates respectively.
As shown in Figure 2, this blast furnace cooling stave needs layer of metal process layer 6 is set on the bonding surface of another metal sheet 2 when the fine copper plate portion is a casting on another metal sheet the time, and this smithcraft layer can be the fine copper overlay cladding, also can be tining layer or brushing coating.
