Abstract
The utility model discloses a copper cooling wall of a blast furnace. The copper cooling wall comprises a cooling pipe, a jacket, a body, a male end, a female end, an inlet and an outlet, wherein the jacket is located at the lower end of the body, the body is connected with the cooling pipe, the male end is connected with the female end, the female end is located on one side of the inlet, the inlet is located on one side of the cooling pipe, the outlet is located on the other side of the cooling pipe and the cooling pipe is located above the body. The copper cooling wall disclosed by the utility model breaks through the traditional concept of iron or steel cooling walls, and the service life of the cooling wall is prolonged by adopting a novel method, thereby optimizing the cooling effect and improving the heat conductive benefit. The cooling water pipe is compactly combined with the body of the cooling wall, so that the cooling effect and the mechanical properties of the cast copper cooling wall are improved.
Description
Technical field
The utility model relates to the technical field of metallurgy high temperature stove, specifically a kind of blast furnace copper cooling stave.
Background technology
In industrial circle; along with improving constantly of industrialization degree; service requirements to mechanical means is also more and more higher; blast furnace copper cooling stave is widely used in some metallurgy industries; cooling stave is to provide cooling equipment for metallurgy high temperature stove; can protect metallurgy high temperature stove to avoid erosion and the mechanical wear of high temperature fluid in body of heater, extend the metallurgy high temperature stove life-span, ensure its safety and stability production.Once cooling apparatus goes wrong, comprehensively stop production to overhaul of metallurgy high temperature kiln, will bring heavy economic losses, so the life-span of cooling stave and performance determine the life-span of metallurgy high temperature stove, is metallurgy high temperature stove long-service life high-efficiency, energy-conservation important guarantee.The cooling stave material that the outer metallurgical industry of Present Domestic generally adopts is taking cast iron and cast steel as main, but cast iron or cast steel cooling wall exist many deficiencies.Taking most popular spheroidal graphite cast iron cast steel cooling wall as example, spheroidal graphite cast iron cast steel cooling wall must add anti-carburization coating outside cooling channel, make to form air gap between passage and matrix, and air gap increases more than 1,000 times cooling stave heat transmission resistance, worsen the heat-transfer effect of cooling stave, increase cooling stave working face temperature, accelerate the breakage of cooling stave, thereby cause cooling stave to shorten work-ing life, increase resource consumption, be unfavorable for cooling stave longevity, energy-conservation, and spheroidal graphite cast iron thermal conductivity and thermal shock resistance are all poor, its thermal conductivity is only little, be unfavorable for the high efficiency cooling of cooling stave.
Utility model content
For the problems referred to above, the utility model aims to provide a kind of blast furnace copper cooling stave.
For realizing this technical purpose, scheme of the present utility model is: a kind of blast furnace copper cooling stave, comprise cooling tube, sheath, body, male end, female end, entrance, outlet, described sheath is positioned at the lower end of body, and described body is connected with cooling tube, and described male end is connected with female end, described female end is positioned at a side of entrance, described entrance is positioned at a side of cooling tube, and described outlet is positioned at the opposite side of cooling tube, and described cooling tube is positioned at the top of body.
As preferably, in described cooling oblate pipe insertion body, communicate with male end and female end.
As preferably, the passage that described male end is connected with female end takes the shape of the letter U.
As preferably, described cooling tube is designed to oblateness.
As preferably, described sheath adopts every cold effective solid wood material.
As preferably, described sheath and body use and are threaded.
As preferably, cooling tube has 4.
The utility model is broken the traditional concept of iron or steel cooling stave in the past, realize cooling performance optimization the work-ing life that adopts novel method to extend cooling stave, the basic material of the material of cooling tube and cooling stave body is all chosen to be cast copper by this cooling stave, effectively avoid the series of problems that uses anti-carburization coating and bring, cooling tube is cast directly over to cooling stave body interior, in casting process, utilize composite solid cooling medium to pass through cooling tube with fluid, protection cooling tube melts and does not change, impel micro-the melting with cooling stave body in cooling tube surface in casting process to fit tightly, do not produce air gap, substantially there is not remelting and recrystallize, keeping the original good rolling performance of cooling tube, and control the process of setting of cooling stave body, form the condition of consecutive solidification, improve the performance of cast copper cooling wall, cast copper cooling wall is placed in the high-temperature area inner side of metallurgy high temperature stove, heat-eliminating medium enters from the lower port of the cooling tube of cast copper cooling wall in the pipeline of entrance and exit connection by certain flow velocity, again by cast copper cooling wall inside, by this way, heat is passed to the cooling stave body of cast copper water cooler from metallurgy high temperature stove inside, heat-eliminating medium again by heat the male end from cooling stave body and female end take metallurgy high temperature stove out of, process of cooling is progressively carried out, avoid the furnace shell of metallurgy high temperature stove to be subject to high temperature erosion simultaneously, thereby extend the work-ing life of metallurgy high temperature stove, by regulating cooling water flow and flow velocity to regulate the cooling performance of cast copper cooling wall.Cooling stave adopts long oblate water-cooled tube, the contact area of increase and heat-eliminating medium, increases the cooling intensity to hot side, has improved thermal conduction benefit, and water-cooled tube and cooling stave body are combined closely, improve cast copper cooling wall cooling performance and mechanical property.
