The furnace base 100 is disposed within the tank 310. The annealing vessel 120 has a material support 130 and an inner cover 140. The material support 130 is disposed on the furnace base 100 and is used to support steel coils. The inner cover 140 accommodates the steel coils. The heating hood 110 has a first cover 150 and a second cover 160. The first cover 150 is located on one side of the furnace base 100, and the second cover 160 is located on the side of the furnace base 100 away from the first cover 150. The first cover 150 and the second cover 160 cooperate to form a semi-enclosed cavity, which accommodates the annealing vessel 120. The first cover 150 and the second cover 160 are movable relative to the furnace base 100 so that the furnace base 100 is exposed.

[0033] First, by setting up a furnace base 100, the present invention can provide multiple annealing tanks 120 on the furnace base 100. The multiple annealing tanks 120 can load a large number of strip steel coils, thereby enabling the annealing and processing of a large number of strip steel coils at one time, thus greatly improving production efficiency.

[0034] Meanwhile, the heating cover 110 is provided with the first cover body 150 and the second cover body 160, the first cover body 150 and the second cover body 160 are movable relative to the furnace base 100, so that the first cover body 150 and the second cover body 160 form a semi-closed cavity, the semi-closed cavity can accommodate a plurality of annealing cans 120, then annealing processing is carried out, so that the heating cover 110 can accommodate the annealing cans 120, and meanwhile, the complex structure of the bell-type annealing furnace can be avoided, and the equipment cost is greatly reduced.

[0035] Further, the first cover body 150 and the second cover body 160 can be moved away from the furnace base 100, so that the first cover body 150 and the second cover body 160 can accommodate maintenance personnel to enter, thereby greatly facilitating the maintenance work of the operating personnel.

[0036] Referring to Figure 3 In some embodiments of the present application, the furnace base 100 has a first support plate 170, the first support plate 170, the first cover body 150 and the second cover body 160 cooperate to form a closed cavity.

[0037] It should be noted that by providing the first support plate 170, the first support plate 170, the first cover body 150 and the second cover body 160 cooperate to form a closed cavity, which can avoid the loss of hot gas during annealing processing, thereby reducing energy consumption.

[0038] Referring to Figure 1 In some embodiments of the present application, the first support plate 170 has a first groove 200, and the first groove 200 accommodates the material supporting seat 130.

[0039] Reasonably, by providing the first support plate 170 with the first groove 200, the first groove 200 can accommodate the seat body, so that the height of the heating cover 110 body can be reduced, the space occupation can be reduced, and at the same time, the strip steel coil can be conveniently transported to the material supporting seat 130, so that a large number of strip steel coils can be processed.

[0040] Referring to Figure 2 In some embodiments of the present application, the first support plate 170 is provided with a first convex edge 180 on the outside, and the first cover body 150 and the second cover body 160 are provided with a first recess 190 on the inside, and the first recess 190 accommodates the first convex edge 180.

[0041] It should be noted that by providing the first support plate 170 with the first convex edge 180, when the first cover body 150 and the second cover body 160 are close to the furnace base 100, the first recess 190 accommodates the first convex edge 180, so that the sealing effect between the furnace base 100, the first cover body 150 and the second cover body 160 is improved, the loss of hot gas is reduced, and the leakage of hot gas is avoided.

[0042] In some embodiments of the present invention, the furnace base 100 is provided with an exhaust duct 280 and a chimney 290 connected to the exhaust duct 280. The chimney 290 is connected to the outside. The inner cover 140 is provided with an exhaust pipe 300, which connects the inner cavity of the heating cover 110 and the exhaust duct 280.

[0043] It is understandable that by providing an exhaust duct 280 to the furnace base 100 and connecting the exhaust pipe 300 to the exhaust duct 280, the flue gas inside the heating hood 110 can pass through the exhaust duct 280 and finally be discharged to the outside through the chimney 290.

[0044] Reference Figure 3 In some embodiments of the present invention, the bottom of the first cover 150 and the second cover 160 are provided with rollers 240, and the ground is provided with guide rails 250, and the rollers 240 roll on the guide rails 250.

[0045] It is understandable that by providing rollers 240 to both the first cover 150 and the second cover 160, when the first cover 150 and the second cover 160 move, the rollers 240 roll the guide rail 250, which can make the first cover 150 and the second cover 160 move smoothly. At the same time, it is convenient for the first cover 150 and the second cover 160 to cooperate to form a semi-enclosed cavity.

[0046] In some embodiments of the present invention, the heating cover 110 has a first power component that drives the first cover 150 and the second cover 160. The first power component has a motor 220 and a transmission chain 230.

[0047] It is understandable that by having the first power assembly have a motor 220 and a transmission chain, the motor 220 can drive the transmission chain 230, and the transmission chain 230 can move the first cover 150 and the second cover 160 closer to the furnace base 100, thereby improving the movement efficiency of the first cover 150 and the second cover 160.

[0048] Reference Figure 1 In some embodiments of the present invention, a burner 260 and a gas pipe 270 connected to the burner 260 are provided at the bottom of the furnace, and the opening of the burner 260 is connected to the first groove 200.

[0049] Specifically, by installing a burner 260 and a gas pipe 270 at the bottom of the furnace, the gas pipe 270 supplies fuel to the burner 260, which generates hot gas, thereby raising the temperature of the annealing tank 120 in the first tank 200, and causing the strip coil to undergo annealing.

[0050] In some embodiments of the present invention, a burner 260 and a gas pipe 270 communicating with the burner 260 are provided inside the heating cover 110, and the opening of the burner 260 is communicating with the semi-enclosed cavity.

[0051] Specifically, by arranging the burner 260 and the gas pipe 270 in the heating cover 110, the gas pipe 270 provides fuel to the burner 260, and the burner 260 can generate hot gas, so that the annealing tank 120 is heated uniformly, and the temperature of the annealing tank 120 is raised as required, so that the strip steel coil is annealed.

[0052] With reference to Figure 3 In some embodiments of the present application, the first cover body 150 is provided with a second protruding edge 210 outside, and the inner cavity of the second cover body 160 contains the second protruding edge 210.

[0053] It should be noted that by arranging the first cover body 150 with the second protruding edge 210, when the first cover body 150 cooperates with the second cover body 160 to form a semi-closed cavity, the inner cavity of the second cover body 160 contains the second protruding edge 210, so that the hot gas can be prevented from dissipating to the workshop, and energy loss is reduced.

[0054] In the description of the present application, the description of the terms "one embodiment", "some embodiments", "exemplary embodiment", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application.
