Abstract
The utility model discloses a bury flat pure copper pipe blast furnace stave, including wall body, inlet channel, outlet conduit and the inside cooling tube of wall body, cooling tube is flat pure copper pipe, and inlet channel, outlet conduit are circular pure copper pipe, and adopt pre-buried pure copper pipe casting shaping, and pre-buried pure copper pipe is by the curved system shaping of whole copper pipe, does not have the welding. The utility model has the advantages of compressive strength is high, no end cap, no welding, and it is little to lead to water resistance, and the furnace wall is thin enlarges the stove appearance.
Description
Technical field
The utility model relates to a kind of Buried Flat Shape Copper pipe blast furnace cooling stave.
Background technology
At present, adopted copper cooling wall on existing tens blast furnaces of iron and steel enterprises of many families such as Germany, Sweden, Belgium and the U.S..The external copper cooling wall that adopts has three kinds of forms: the MTT cast tube copper cooling wall of (1) Huo Gaowen company, adopted the castmethod manufacturing, and be cast into body with the Monel pipe as water-cooled tube; (2) PW-OU type cooling stave is 99% continuous casting copper coin base manufacturing, and the cooling channel is oblate type and moulding in the crystallisation process of continuous casting; (3) the SMS copper cooling wall that has MANGHH to develop adopts rolling thick copper coin to be welded, and the material copper content is greater than 99.95%.In essence, rolling copper cooling wall, the compactness of its tissue is slightly better than a farmland than the casting copper cooling wall, is difficult to processing but its shortcoming is a heterotypic channel, more can not process the cooling stave that has radian, and the water flowing resistance is big.Continuous casting type technology has solved the unmanageable difficulty of profiled holes, but has lost the advantage of stable performance.In addition, more than two kinds of technologies all need after body forms, to adopt mode " adapter ", " plug-hole " that welds, because the welding of copper is difficulty (workpiece must be preheated to 700～800 ℃) relatively, so for cold workpiece large-scale as copper cooling wall, adapter and plug-hole welding cost are higher, and quality is difficult for guaranteeing---form defectives such as stress concentration, crackle and slag inclusion easily, and then influence use properties, stay potential safety hazard.In addition, " adapter " or " plug-hole " causes the rough of water stream channel easily, improves the resistance of water, causes the waste of the energy.Because machining cost increases, the rolling copper cooling wall that causes holing costs an arm and a leg, and competitive power descends.The MTT cast tube copper cooling wall of Huo Gaowen company is cast into body with the Monel pipe as water-cooled tube, because the thermal conductivity of Monel pipe is well below the thermal conductivity of fine copper, its heat conductivility of the copper cooling wall that casts out is had a greatly reduced quality.
The utility model content
The purpose of this utility model is to provide a kind of Buried Flat Shape Copper pipe blast furnace cooling stave, has the ultimate compression strength height, and no plug does not have welding, and the water flowing resistance is little, the thin advantage that enlarges heat size of furnace lining.
In order to achieve the above object, the technical solution of the utility model is:
The utility model is a kind of Buried Flat Shape Copper pipe blast furnace cooling stave, comprises the cooling duct 4 of wall body 1, inlet channel 2, outlet conduit 3 and wall body inside, and cooling duct 4 is the flat pure copper tube, and inlet channel 2, outlet conduit 3 are circular pure copper tube.
Described flat cooling duct 4 and circular inlet channel 2, outlet conduit 3 adopt pre-buried pure copper tube casting, and pre-buried pure copper tube bends moulding by whole copper pipe, does not have welding.
After the utility model adopts technique scheme, its beneficial effect is: cooling duct is the flat pure copper tube, inlet channel, outlet conduit are the integral structure of circular pure copper tube, solved like this between cooling copper tube and inlet channel and the outlet conduit and do not had plug, do not have welding, the water flowing resistance is little, the ultimate compression strength height, do not have the hidden danger of leaking, use is without fear of an attack from the rear.Cooling copper tube adopts flat tube, can increase cooling area, improves the cooling stave cooling power, the thickness of attenuate cooling stave body, enlarge heat size, this cooling duct, inlet channel, outlet conduit, body adopts the one-step casting moulding need not machining, has significantly reduced mach workload, and construction is simple, and have a long service life, the advantage that cost is low.

Embodiment
As shown in Figures 1 to 4, the utility model comprises wall body 1, inlet channel 2, the cooling duct 4 of outlet conduit 3 and wall body inside; Cooling duct 4 is the flat pure copper tube, inlet channel 2, and outlet conduit 3 is circular pure copper tube, adopts graphite casting mould, is bent into wall body internal cooling pipeline 4 by whole copper pipe and is flat, inlet channel 2, outlet conduit 3 are circular integral structure.
