Abstract
A high cooling performance rapid pure copper cooling wall comprises a wall body composed of a cold half and a hot half by welding, wherein two halves are all made of a rolled pure copper plate; a group of longitudinal cooling medium channels are arranged at the side of a faying face of one half or simultaneously at the side of the faying face of two halves; the channel may have a section including circle, compound circle, flat circle and other irregular section including rectangle and trapezoid. Four corners of the faying face of two halves are respectively provided with a welding groove by welding and, after combining two halves, a circumference can become integral by a continuous welding. In order to increase a combination strength of two halves, at a proper position, a group of through screws is added along a thickness extension of the wall body, with a material used for manufacturing the through screw same as that used for manufacturing the wall body. Two end planes of the through screw are inferior respectively to the hot plane (one plane towards the inside of a blast furnace) and the cold plane (one plane towards the outside of the blast furnace) of the wall body by 5 to 8 mm, with a flat plug welding. The cooling wall has outstanding heat conductivity. Especially for a combined structure, the cooling medium channel, keeping opening before the combination, can be processed into free shape by planning and milling to obtain a large heat exchange area, which makes no processing hole existent at two ends and bypasses the plug welding, characterized in well quality, high production rate and low cost.
Description
Affiliated technical field
The utility model relates to a kind of combined fine copper cooling stave, belongs to the blast furnace body cooling apparatus.
Background technology
Cooling stave is the blast furnace body cooling apparatus, is undertaking the vital task of protecting furnace shell, supporting refractory materials and safeguard reasonable furnace.The life-span of blast furnace depends primarily on the life-span of cooling stave.Grey cast iron cooling stave, heat resisting iron cooling stave, high-toughness ductile iron cooling stave, cast steel cooling wall and copper cooling wall have been experienced in the development of cooling stave.Copper cooling wall makes that cooling stave hot side (one side in stove) temperature is low owing to have very high thermal conductivity, forms the protectiveness slag crust easily, more and more is subjected to the attention and the approval of domestic and international iron industry.But present structural limitations owing to copper cooling wall, the manufacturing process complexity, productivity is low, costs an arm and a leg, and it is applied be restricted, and many iron works are unable to reach.
At present, the blast furnace copper cooling wall mainly contains two types both at home and abroad: a kind of is that continuous cast copper base is made wall body, copper content≤99.0%, and thermal conductivity ≈ 300W/ (m.K), the cooling medium pass cross-sectional shape adopts oblate.Because under the situation that sectional area equates, the girth in oblate cross section is greater than the girth of rounded section, so the heat exchange area in oblate cross section is greater than the heat exchange area of rounded section.But the purity of continuous casting copper base is low, and material is loose, so thermal conductivity is low, makes the heat-eliminating medium consumption increase equipment working cost height.Another kind of cooling stave is to adopt rolled copper slab to make wall body, copper content 〉=99.9%, thermal conductivity 〉=370W/ (m.K), but cooling medium pass can only be processed into circle by depth drill, not only heat exchange area is little for this rounded section passage, and influenced by deep hole chip removal difficulty, drill bit inconvenience cooling etc., productivity is low, and is with high costs.In order to improve heat exchange area, also have and adopt compound rounded section passage, but that this compound rounded section passage bores system speed is lower, be difficult to large-scale production.
In order to take into account the copper cooling stave high heat conductance of blast furnace, big heat exchange area, high productivity and low-cost problem, the utility model provides a kind of combined fine copper cooling stave, this cooling stave thermal conductivity height, heat exchange area are big, uncovered processing cooling medium pass is very easy before the combination, and be not subjected to the restriction of cross-sectional shape, productivity height, cost are low.
The technical scheme that its technical problem that solves the utility model adopts is: wall body is formed by huyashi-chuuka (cold chinese-style noodles) halfbody and hot side halfbody assembly welding, and two halfbodies are all used highly purified rolled copper slab manufacturing.The bonding surface side of a halfbody or while are offered one group of vertical cooling medium pass in the bonding surface side of each halfbody therein.The cross-sectional shape of passage can be circle, compound circle, oblateness and other special crosssection, as rectangle, trapezoidal etc.Passage can be finished by methods such as the pins of planing, mill, owing to be uncovered processing, very convenient.Edges and corners are processed with bevel for welding around two halfbody bonding surfaces, and it is one that two halfbodies merge back continuous welding all around, and the material and the wall body of weld seam filler metal are identical.In order to increase by two bonding strengths between the halfbody, in position, set up one group of drift bolt along the wall thickness direction, the material of drift bolt and wall body are also identical, and than wall body hot side and the low 5～8mm of huyashi-chuuka (cold chinese-style noodles), plug welding is smooth respectively for the both ends of the surface of drift bolt.The passage two ends connect at wall body huyashi-chuuka (cold chinese-style noodles) one face down bonding the water inlet pipe and water outlet pipe of axis normal in channel centerline are installed, and offer open holes and the thermometer hole of axis normal in channel centerline on the wall body.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 within the protective tube of wall body huyashi-chuuka (cold chinese-style noodles), and weldering is one with it.
Unusual effect of the present utility model is: when having kept the copper coin high thermal conductivity, increased heat exchange area again, especially the assembly welding structure makes that the uncovered processing of cooling medium pass is very easy, the productivity height, and cost reduces greatly.
Below in conjunction with drawings and embodiments the utility model is further specified.
