As shown in fig. 1 in combination with fig. 2, 3 and 4, the deformation limiting metallurgical furnace in this embodiment includes a plurality of furnace shell copper steel composite water jackets 100 and a plurality of furnace bottom copper steel composite water jackets 200. As can be seen in fig. 1, two adjacent shaft copper steel composite water jackets, for example, a shaft copper steel composite water jacket 101 and a shaft copper steel composite water jacket 102, are welded to each other. The copper-steel composite water jackets of the furnace bodies on the same plane are welded with each other to form a plane of the furnace body.

Further, as shown in the previous figures, the shaft copper steel composite water jacket 100 includes a first copper layer 110 of a hot face and a first steel layer 120 of a cold face, and as can be seen from the back of the shaft copper steel composite water jacket 100, the first steel layer 120 includes a steel rim 121 on the periphery and a reinforcing rib 122 on the inside of the steel rim. When two adjacent furnace body copper steel composite water jackets are connected, the steel edges of the first steel layers of the two furnace body copper steel composite water jackets are mutually attached, and can be mutually welded at a plurality of adjacent positions so as to tightly connect the two adjacent furnace body copper steel composite water jackets. In some embodiments, a plurality of furnace body copper steel composite water jackets on the same plane can be welded through mutually-fitted steel edges.
FIG. 5 is a schematic view of a joint of two adjacent two copper steel furnace body composite water jackets on the same plane according to an embodiment of the present application, as shown in FIG. 5, for the copper steel furnace body composite water jackets on the same plane, in some embodiments, a bending structure is disposed on the other side of the copper steel furnace body composite water jacket 101, the bending structure includes a bending surface 113 parallel to the copper steel composite surface and located at the first copper layer, the bending structures of the two adjacent copper steel furnace body composite water jackets are adapted to each other in a concave-convex manner, and an expansion gap of 15-60mm is reserved between the two adjacent copper steel furnace body composite water jackets by tightly lapping the bending surfaces. As shown in fig. 4, the bending structure of the furnace body copper steel composite water jacket 103 which is positioned on the same plane with the furnace body copper steel composite water jacket 101 is matched with the bending structure in a concave-convex manner, and the furnace body copper steel composite water jacket are tightly lapped together through the bending surface 113.
FIG. 6 is a schematic illustration of the overlap of two adjacent planar shaft copper composite water jackets of one embodiment of the present application, as for a shaft copper composite water jacket on two adjacent sides, in some embodiments, the edge of the shaft copper composite water jacket 102 has a recess 112 along its width, and the side of the other planar shaft copper composite water jacket 101 is disposed at the recess 112, with an expansion gap of 15-70mm from the end face of the recess 112. The first copper layer of the furnace copper steel composite water jacket 101 is lapped on the first copper layer protruding from the concave table 112 in the furnace copper steel composite water jacket 102, and the contact surfaces are closely lapped together.
By the lap joint mode of the two specific embodiments, a plurality of furnace body water jackets on the same plane are overlapped together in a concave-convex mode, and the furnace body water jackets on the adjacent two planes are overlapped together at a vertical angle, so that a staggered lap joint structure is realized to form the furnace body of the metallurgical furnace.

Further, the deformation of the shaft can be effectively restricted. The reserved expansion gap reserves space for the expansion of the copper layer when heated. The specific gap size can be adjusted according to the practical application, and preferably the expansion gap is reserved for 25mm.
FIG. 7 is a schematic view of the structure of a hearth copper-steel composite water jacket according to one embodiment of the present application, wherein the metallurgical furnace hearth is positioned on the hearth of the hearth-supporting metallurgical furnace, and the hearth is formed by welding a plurality of hearth copper-steel composite water jackets 200, as shown in FIG. 1 in combination with FIG. 7. The hearth copper steel composite water jacket 200 includes a jacket body 210 located inside the hearth and a jacket edge 220 extending from the hearth to the outside thereof, the jacket body 210 including a second copper layer 211 on a hot side and a second steel layer (not shown in the drawings) on a cold side, the jacket edge 220 including a third steel layer 221 located on a surface, and the third steel layer 221 of the hearth copper steel composite water jacket 200 and the first steel layer 120 of the adjacent shaft copper steel composite water jacket 100 are welded to each other at a plurality of positions.
Wherein the furnace bottom copper steel composite water jacket 200 and the furnace body copper steel composite water jacket 100 are tightly bonded without separation between the first copper layer 110 and the first steel layer 120 and between the second copper layer 211 and the second steel layer during thermal expansion and contraction.
The cold surfaces of the water jackets are all steel surfaces, so that the water jackets are easy to install on site, and the damage of pure copper water channels is avoided, and the water jackets are not easy to maintain. Meanwhile, the steel surface is easy to weld, and the leakage of substances in the furnace can be avoided, so that potential safety hazards are generated.
A limit groove 230 is arranged between the sleeve body 210 and the sleeve edge 220 of the furnace bottom copper steel composite water jacket 200, and the furnace body copper steel composite water jacket 100 is arranged in the limit groove 230.

Alternatively, according to embodiments of the present application, all water jackets on the shaft are explosion-clad copper steel composite water jackets. In the cooling process of the copper-steel composite board manufactured by traditional composite technology such as rolling composite and melt overlaying, due to the fact that the linear expansion coefficients of the steel plate and the copper plate are different, the steel plate is internally provided with densely distributed cracking cracks, erosion resistance to molten liquid or slag is reduced, a steel layer and a copper layer are not tightly combined, and the mechanical strength of the composite board is low. However, the explosion welding composite technology in the embodiment can weld two metals of copper and steel with larger difference of physical properties together, increase the bonding area of the composite plates, avoid the defect of larger size, effectively improve the bonding strength of the bonding position and basically avoid the change of the structure and the performance of the welded metal plates.
With continued reference to FIG. 7, optionally, the rim 220 of the hearth copper steel composite water jacket 200 further includes a third copper layer 222 extending from the second copper layer 211 to the rim and a fourth steel layer 223 extending from the second steel layer to the rim, in accordance with an embodiment of the present application. The hearth copper steel composite water jacket 200 needs to support the shaft copper steel composite water jacket 100 and the dropped slag, so that sufficient mechanical strength is required. In some embodiments, the higher thickness of the fourth steel layer 223 of the rim provides more stable support to the entire furnace shaft and also increases the life of the furnace bottom.
FIG. 8 is a schematic view of the configuration of a shaft stop according to one embodiment of the present application; fig. 9 is a schematic view of a shaft stop according to another embodiment of the present application. As shown in fig. 8 and 9, according to an embodiment of the present application, optionally, the furnace body limiting device is further included, and the furnace body limiting device is sleeved around the middle part of the furnace body and is tightly connected with the furnace body copper steel composite water jacket in the middle part of the furnace body, so as to limit expansion of the furnace body copper steel composite water jacket in the middle part of the furnace body. The furnace body limiting device can effectively limit the deformation of the furnace body and prolong the service life of the metallurgical furnace.
In some embodiments, as shown in fig. 5, the shaft limiter may be a steel frame 301 that is installed around the shaft, where the steel frame 301 is fastened to the shaft copper-steel composite water jacket 100 in the middle of the shaft, and limits expansion of the shaft copper-steel composite water jacket in the middle of the shaft.
In some embodiments, as shown in fig. 9, the shaft stop may be a jack 50 that abuts the shaft water jacket. The two claws of the jack 50 respectively support the upper and lower parts of a shaft copper steel composite water jacket 100, and when the pressure in the furnace increases due to the reaction in the metallurgical furnace, the jack can support the shaft water jacket to limit excessive deformation of the shaft water jacket when the shaft expands outwards. With continued reference to fig. 9, in some embodiments, each of the shaft copper composite water jackets 100 may be provided with one or more jacks, which may be secured to the steel frame 301.
Fig. 10 is a view from direction a of fig. 8, and in other embodiments, as shown in fig. 10, the shaft stop may further include a hoop 302 disposed around the shaft, and in some embodiments, the hoop 302 is transverse and has two ends fixed to a steel frame 301, and the amount of deformation of the metallurgical shaft is limited by clasping the water jacket of the shaft. In other embodiments, a longitudinal hoop can be further arranged to longitudinally limit the water jacket of the furnace body and the water jacket of the furnace bottom, and the longitudinal hoop can be matched with the transverse hoop to form a netlike hoop structure.
Optionally, according to an embodiment of the present application, the first steel layer 120 of the shaft copper steel composite water jacket 100 comprises a plurality of fastening elements (not shown in the figures) thereon for fastening connection between adjacent shaft copper steel composite water jackets. Further, for the adjacent furnace body copper steel composite water jackets on the same plane, the fastening elements enable two steel edges of the adjacent furnace body copper steel composite water jackets to abut against and form surface contact, and steel welding after gaps appear is facilitated.
Besides different limiting devices arranged outside the furnace body, a plurality of fastening elements for reinforcing connection are also arranged between every two adjacent furnace body copper steel composite water jackets. The gap is possibly cracked between the two water jackets due to infirm welding or overlarge deformation caused by thermal expansion, and the plurality of fastening elements can effectively tighten the copper-steel composite water jackets of the two adjacent furnace bodies, so that the steel edges between the two water jackets are tightly attached together without generating overlarge deformation, the welding seams between the two water jackets are ensured not to crack, and the service life of the metallurgical furnace is prolonged.
FIG. 11 is a schematic illustration of steel plates welded to a steel rim of a shaft copper composite water jacket of one embodiment of the present application, as shown in FIG. 11, in some embodiments, for a shaft copper composite water jacket adjacent on a non-identical plane, in combination with two shaft water jackets adjacent on different planes of the shaft copper composite water jacket 101 and the shaft copper composite water jacket 102 of FIG. 1, wherein the steel rim of one shaft copper composite water jacket 101 is welded with a steel plate 401 and includes fastening elements (not shown) on the steel plate 401 that are fastened to each other to join the steel rim of the other shaft copper composite water jacket with the fastening elements of the other shaft copper composite water jacket in face-to-face contact with the side of the steel plate 103 and facilitate steel welding after gaps occur without staggering the copper layers of the hot faces of the two adjacent shaft copper composite water jackets. The shape of the plate 401 may be adapted to the actual situation, and in some embodiments the plate 401 may be an extended inclined plate with an inclination angle θ, typically about 60 °.
As shown in fig. 7, the sleeve body 210 of the hearth copper steel composite water jacket further includes a fifth steel layer 212 on the second copper layer 211 of the hot face. Further, as shown in fig. 2, the shaft copper steel composite water jacket further includes a sixth steel layer (not shown) on the first copper layer 110 of the hot face.
