Description

Technical Field

[0001] This utility model belongs to the field of hot rolling technology, and specifically relates to a surface treatment device for N10276 nickel-based alloy hot continuous rolling strip in the finishing rolling zone. Background Technology

[0002] N10276 nickel-based alloy is a nickel-based corrosion-resistant alloy composed of elements such as nickel, molybdenum, chromium, iron, cobalt, and carbon. This alloy possesses excellent corrosion resistance, resistance to thermal stress cracking, good mechanical properties, and good weldability, making it suitable for industries such as chemical, marine, power, and oil refining. However, during the finishing rolling of N10276 nickel-based alloy slabs using a finishing mill, the high-temperature slab's contact with outside air causes oxide scale to form on its surface. This oxide scale can lead to uneven contact between the rolls and the alloy surface during rolling, affecting the alloy's dimensional accuracy and surface quality. It may also penetrate the alloy during rolling, reducing its corrosion resistance and mechanical properties.

[0003] A search revealed a finishing mill unit with prior art announcement number CN222077604U that facilitates surface cleaning of steel strip. This device involves installing two cleaning hoods symmetrically on a single mill, with each hood individually equipped with a cleaning brush roller, motor, dust collection box, negative pressure pump, and dust collection pipe. It also utilizes a dust collection chamber and dust collection holes to centrally extract and store the dust after cleaning the steel strip surface. However, the cleaning brush rollers, upon contacting the steel strip surface, brush away the oxide scale generated during hot rolling. This oxide scale is relatively large and difficult to clean into the dust collection box, resulting in oxide scale residue on the steel strip surface. This causes uneven contact between the rolls and the steel strip surface, or the scale being pressed into the steel strip during the rolling process.

[0004] A search revealed a descaling mechanism for precision-rolled steel plates, with prior art publication number CN 220426320 U. This device uses high-pressure water for descaling, effectively blowing away most of the scale while cooling the steel plate. The device can also fix steel plates of different thicknesses by adjusting the height of the lifting seat. However, after the high-pressure water removes the oxide scale, residue remains on the steel plate surface, causing a rapid drop in temperature. Furthermore, during the cleaning process with a cleaning brush, residual oxide scale and high-pressure water continuously fall from the sides of the steel plate, causing a rapid drop in edge temperature. This results in cracking or deformation of the steel plate during the precision rolling process due to excessive temperature differences between the sides and the center. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a surface treatment device for N10276 nickel-based alloy hot-rolled strip in the finishing rolling zone. This invention, through the cooperation of a recycling mechanism and a descaling mechanism, performs multi-stage cleaning in accordance with the movement direction of the hot-rolled plate, and can also recycle the cleaning water used in the cleaning process and the oxide scale removed.

[0033] A surface treatment device for N10276 nickel-based alloy hot-rolled strip in the finishing zone, the working process of which is as follows:

[0034] When hot-rolled plate 5 is rolled using a finishing mill, it will repeatedly pass through the mill. At this time, it is necessary to control the operation of the two sets of descaling mechanisms 2 according to the direction of movement of the hot-rolled plate 5; as shown in the attached... Figure 1 As shown, when the hot-rolled plate 5 moves to the left, the descaling mechanism 2 on the left side of the recycling mechanism 1 operates, and the descaling mechanism 2 on the right side of the recycling mechanism 1 stops operating. At the same time, the descaling mechanism 2 on the right side controls the flipping mechanism 203 to lift upward; the opposite is true when the hot-rolled plate 5 moves to the right.

[0035] The electric pusher cylinder II 301 in the lifting mechanism 3 operates synchronously, causing the connecting frame 303 to control the lifting and lowering of the recycling mechanism 1, thereby driving the guide trough 201 in the descaling mechanism 2 to approach the surface of the hot-rolled plate 5; subsequently, the electric pusher cylinder I 2033 in the flipping mechanism 203 operates synchronously, controlling the sliding seat 2036 to slide in the guide groove 2034, thereby driving the rotating plate 2035 to flip up and down; when the rotating plate 2035 flips upward, the spray pipe 2041 and the air inlet pipe 2042 in the cleaning mechanism 204 follow the rotating plate 2035 away from the hot-rolled plate 5. At this time, the descaling mechanism 2 is in a stopped state. When the rotating plate 2035 flips downward, the spray pipe 2041 and air inlet pipe 2042 in the cleaning mechanism 204 follow the rotating plate 2035 to approach the surface of the hot-rolled plate 5. At this time, the high-pressure water source and air compressor spray a high-pressure water-air mixture onto the surface of the hot-rolled plate 5 through the spray pipe 2041, thereby performing the first cleaning of the oxide scale generated on the surface of the hot-rolled plate 5 during the finishing rolling process. At the same time, the high-pressure air source sprays air blades through the air inlet pipe 2042 to perform the second cleaning of the oxide scale on the surface of the hot-rolled plate 5.

[0036] Subsequently, the electric pusher cylinder II 2044 cooperates with the rack 2045 to control the gear I 2046 and gear II 2047 to drive the spray pipe 2041 and air inlet pipe 2042 to rotate upward. Thus, with the help of the high-pressure water-air mixture sprayed from the spray pipe 2041 and air inlet pipe 2042 and the thrust generated by the air blade, the oxide scale cleaned from the surface of the hot-rolled plate 5 is pushed into the collection box 101 through the guide groove 201. At the same time, the air blade sprayed from the air inlet pipe 2042 will also push the water sprayed from the spray pipe 2041 into the guide groove 201, thereby reducing the time that water remains on the surface of the hot-rolled plate 5.

[0037] At the same time, the air pump extracts the air from the recycling box 6 through the connection port 601, making the recycling box 6 under negative pressure. At this time, the control valve opens the connection pipe 602 connected to the descaling mechanism 2 in operation, and the cleaning water near the guide trough 201 is pumped into the recycling box 6 through the recycling pipe 202 and the water inlet pipe 2021. After the water in the recycling box 6 accumulates to a certain amount, the control valve on the drain pipe 603 is opened to drain the water.

[0038] While the scale collection box 101 is in operation, the motor 103 drives the conveyor belt 104 to rotate via the rotating roller 105, and the scale is discharged from the recycling mechanism 1 through the discharge port 1011.
