Abstract
Disclosed is a copper plate cooling wall with compound holes. A wall body is made by flattening fine copper plates. One longitudinal end of the wall body is opened with a longitudinal passage of which the cross section is of a compound-hole-typed shape. Each compound-hole type is formed by 2-4 circles with same radius which are partially overlapped with each other. The radius of the circle is 10-20 millimeters, and the centre of circle of each circle is placed at the same straight line which is parallel to a heating surface of the wall body. The sectional area of the passage is equal to the sectional area of an inlet (outlet) pipe. The compound-hole type is formed by lateral drilling. The depth of the hole is less than or equals to 3 meters, and the centre deviance is + - 1.5 millimeters / meter. The formed technical hole is blocked by a block head made of same materials as the wall body and is tightly welded. The other end of the passage is a blind hole. The cooling wall increases heat conductivity as well as the heat exchanging area. The utility model has the advantages of reasonable structure and reduced costs.
Description
Affiliated technical field
The utility model relates to the compound pass cooling stave of a kind of copper coin, belongs to the blast furnace body cooling apparatus.
Background technology
At present, the copper cooling stave of known blast furnace has two types, and a kind of cooling stave is to make wall body with the continuous casting copper base of copper content≤99.90%, thermal conductivity ≈ 300W/m. ° k, and its cooling medium pass cross-sectional shape adopts oblate.This cooling stave is when channel cross-sectional area is identical with circular cross-sectional area, because oblate girth is greater than circular girth, so the oblate passage heat exchange area of counting out is greater than the circular passage heat exchange area.But,, the consumption of its heat-eliminating medium is increased so thermal conductivity is lower because of continuous casting copper base material is loose.Another kind of cooling stave is to make wall body with the calendering fine copper plate of cupric 〉=99.90%, thermal conductivity 〉=370W/m. ° k, has improved the wall body thermal conductivity, but because of processing difficulties, the shape of its channel cross-section all is circular, and the heat exchange area of this circular passage is less.
Summary of the invention
In order to solve the problem that copper cooling stave high heat conductance of existing blast furnace and big heat exchange area can not get both, the utility model provides a kind of copper coin compound pass cooling stave, and it is not only rational in infrastructure, and good cooling results, and cost is low.
The technical scheme that its technical problem that solves the utility model adopts is: the cooling stave wall body is made of the calendering fine copper plate of copper content 〉=99.90%, thermal conductivity 〉=370W/m. ° k.The vertical passage that the vertical end of wall body offers with longitudinal cenlerline and parallels, width between centers equates, the channel cross-section shape adopts compound pass, each compound pass is made of 2～4 mutual circles partly overlapping, that radius is identical, this radius of circle is between 10～20mm, center of circle of each circle is all on same straight line, and this straight line parallel is in the cooling stave hot side.Owing to adopt single-sided process technology, at an end of vertical passage fabrication hole is arranged, and be blind hole at the other end, fabrication hole uses the plug identical with the wall body material to block and weld extremely.The passage two ends connect at huyashi-chuuka (cold chinese-style noodles) one face down bonding of wall body and axis normal are installed in channel centerline and the water inlet pipe and water outlet pipe that communicates with passage, offer open holes and the thermometer hole of axis normal in channel centerline on the wall body.The hot side of wall body can be the light face, also can process the horizontal dovetail-indent that is parallel to each other.This cross sectional area should equal into the sectional area of (going out) water pipe, and water inlet pipe and water outlet pipe adopts weldless steel tube or seamless copper pipe.Water inlet pipe and water outlet pipe inserts and is welded in the stiffening ring of wall body huyashi-chuuka (cold chinese-style noodles), and is welded into one with it.
The beneficial effects of the utility model are when keeping the copper coin high heat conductance, to have increased heat exchange area again.Because the cross-sectional shape of cooling channel adopts compound pass can make the wall thickness size reach minimum, thereby saves a large amount of pure copper materials, has reduced cost.
