The bimetallic blast furnace water-cooling wall structure comprises a hot surface and a cold surface, wherein cooling water runners are oppositely formed between the hot surface made of a copper plate and a cold surface made of a steel plate; an intake pipe and a discharge pipe are arranged on the cold surface. The bimetallic blast furnace water-cooling wall structure is characterized in that the periphery after the hot surface and the cold surface are combined is connected by virtue of an electronic beam welding line; the electronic beam welding line is 4-6mm wide and 45-55mm deep; multi-point electronic beam penetration welding seams arranged in a matrix are arranged on the cold surface correspondingly to the cooling water runners; the arrangement line-width L of the electronic beam welding line is 150-280mm; the row pitch M is 300-400mm. Compared with the prior art, the bimetallic blast furnace water-cooling wall structure has the beneficial effects that penetrating welding is carried out by adopting an advanced electronic beam technology, a V-shaped groove is not required, the manufacturing difficulty is reduced, the water-cooling wall is high in production efficiency, and good in electronic beam welding property, and the welding line does not easily crack when the blast furnace is used.
Description
Technical field
The utility model relates to blast furnace water-cooling wall field, relates in particular to a kind of bimetallic blast furnace water-cooling wall construction.
Background technology
Because copper cooling wall has the good capacity of heat transmission, can not only form stable slag crust, even in the time that slag crust comes off, also can regenerate fast slag crust, on blast furnace, adopt copper cooling wall, one of important technique measure improving blast furnace campaign, copper cooling wall widespread use on blast furnace in recent years.Because the price of copper cooling wall is more expensive, for reducing costs under the prerequisite ensureing blast furnace longevity, in recent years, there is the bimetal cooling wall of steel copper combination, as the patent No.: mention in 03232865 " blast furnace cooling stave of copper and iron containing alloy combination ", hot-face layer adopts copper material, huyashi-chuuka (cold chinese-style noodles) layer adopts steel or cast iron, huyashi-chuuka (cold chinese-style noodles) layer and hot-face layer are combined by nut and are fastening, all carry out sealing on contact surface between two-layer, the passage that the cavity that contact surface position does not form between two-layer is water coolant; The patent No.: the cooling stave that 200720000008 " a kind of cooling staves " have adopted two metal plates to be welded along periphery, inside establish water-cooling channel and intake-outlet.Two metal plates can be the combinations of steel-copper, can be also the combinations of casting iron/copper.Can on two metal plates bonding surface, be opposite opened water-cooling channel is set, water-cooling channel also can be set respectively in two metal plates.Above-mentioned prior art all can not solve the cooling water leakage problem that blast furnace water-cooling wall causes because of high temperature deformation well, and traditional welding technique need be opened V-butt simultaneously, and manufacture difficulty is large, and production efficiency is low.
Summary of the invention
The purpose of this utility model is to provide a kind of bimetallic blast furnace water-cooling wall construction, introduces electron beam welding technology, optimizes manufacturing process, ensureing, under the prerequisite of blast furnace longevity, to reduce manufacturing cost, improves the production efficiency of cooling stave simultaneously.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of bimetallic blast furnace water-cooling wall construction, comprise hot side and huyashi-chuuka (cold chinese-style noodles), between the huyashi-chuuka (cold chinese-style noodles) that the hot side that copper coin is made and steel plate are made, split and form water coolant runner, water inlet pipe and rising pipe are all located on huyashi-chuuka (cold chinese-style noodles), described hot side is connected by electron beam weld with the periphery after huyashi-chuuka (cold chinese-style noodles) combination, the wide 4～6mm of described electron beam weld, dark 45～55mm; On described huyashi-chuuka (cold chinese-style noodles), corresponding water coolant runner interval is arranged multiple spot electron beam and penetrates weld seam.
The arrangement line-spacing L that described electron beam penetrates weld seam is that 150～280mm, row are 300～400mm apart from M.
Compared with prior art, the beneficial effects of the utility model are: adopt the mode of steel copper combination, can greatly reduce manufacturing cost, water channel manufacture difficulty reduces, and water channel setting is more reasonable, strengthens cooling performance; Adopt advanced electron beam technology to carry out penetrance welding, need not open " V " shape groove, manufacture difficulty reduces, production efficiency is high, electrons leaves welding input heat is little, not yielding, heat affected zone is less (almost not having), and welding property is better, in the process that cooling stave uses at blast furnace, weld seam is not easy to crack.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
See Fig. 1 to Fig. 3, it is a kind of bimetallic blast furnace water-cooling wall section structure example structure schematic diagram of the utility model, comprise hot side 1 and huyashi-chuuka (cold chinese-style noodles) 2, between the huyashi-chuuka (cold chinese-style noodles) 2 that the hot side 1 that copper coin is made and steel plate are made, split and form water coolant runner 3, water inlet pipe and rising pipe 4 are all located on huyashi-chuuka (cold chinese-style noodles) 2, hot side 1 is connected by electron beam weld 5 with the periphery after huyashi-chuuka (cold chinese-style noodles) 2 combinations, the wide 4～6mm of electron beam weld 5, dark 45～55mm; On huyashi-chuuka (cold chinese-style noodles) 2, corresponding water coolant runner 3 intervals are arranged multiple spot electron beam and penetrate weld seam 6.
The arrangement line-spacing L that electron beam penetrates weld seam 6 is that 150～280mm, row are 300～400mm apart from M, adopting advanced electron beam welding technology from huyashi-chuuka (cold chinese-style noodles) 2(steel plate) direction carries out penetrance welding, steel plate and copper coin are firmly welded together by multiple spot, ensure that cooling stave weld seam in blast furnace use procedure is not easy to crack.
