Description

Technical Field

[0001] This utility model belongs to the field of annealing technology for hot-rolled nickel-copper alloy coils, and specifically relates to a descaling and descaling device for annealing N04400 hot-rolled nickel-copper alloy coils. Background Technology

[0002] The chemical composition of N04400 nickel-copper alloy includes carbon, iron, nickel, manganese, silicon, sulfur, and copper. The main components are nickel (Ni) and copper (Cu). In terms of physical properties, N04400 alloy has high density and thermal conductivity, good thermal expansion properties, good fatigue resistance and impact toughness, and strong corrosion resistance. During hot continuous rolling, a large amount of oxide scale is generated on the surface of N04400 nickel-copper alloy after annealing, requiring descaling. However, existing descaling devices are weak in removing oxide scale adhering to the surface of N04400 nickel-copper alloy, and they easily press the removed oxide scale back into the surface, thus affecting the quality of the N04400 nickel-copper alloy.

[0003] A search revealed a high-efficiency descaling device for steel strips with existing technology announcement number CN222820970U. This device includes a fixed base, a first guide frame, a second guide frame, a third guide frame, and a descaling roller. The first, second, and third guide frames are sequentially spaced on the fixed base. A first guide roller is mounted on the first guide frame, a second guide roller on the second guide frame, and a third guide roller on the third guide frame. The second guide roller is positioned at a higher height than the first and third guide rollers. The descaling roller is positioned on the second guide frame and below it. However, this device has the following drawbacks: it can remove poorly adhered oxide scale, but it cannot clean oxide scale adhering to the surface of the steel strip, especially oxide scale pressed into the steel strip by the first guide roller.

[0004] A search revealed an adjustable wrap angle stretch bending straightening machine (CN111229835B) comprising a steering roller, an inlet tension roller group, a roller distance scale, a roller distance moving screw cover, a lower roller distance moving mechanism, a protective cover, an outlet tension roller group, a lower roller distance moving mechanism, an upper roller distance moving mechanism, a roller distance indicator, a wedge block, a central connecting column, a frame, a lifting platform, a lifting platform motor, and a lifting synchronous connecting rod. The steering roller, inlet tension roller group, first bending roller, intermediate bending roller, straightening roller, and outlet tension roller group are arranged sequentially according to the direction of strip steel travel. However, this process has the following drawbacks: after descaling with the bending rollers, the strip is directly straightened by the straightening rollers, which can easily cause the oxide scale to be pressed back into the steel strip, affecting the quality of the steel strip. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a descaling device for annealing N04400 nickel-copper alloy hot-rolled plate and coil. In the descaling mechanism, high-pressure water can impact the broken oxide scale, further achieving the effect of removing the oxide scale; the brushing mechanism can adjust the spray angle of the high-pressure nozzle to improve the descaling efficiency; it can make the cleaning brushes staggered to prevent oxide scale residue on the surface of the nickel-copper alloy plate; and the adjustment mechanism can prevent oxide scale from getting stuck on the cleaning brushes.

A pair of support arms are symmetrically fixed to the side wall of the support frame. Both ends of the high-pressure water pipe are rotatably connected to the support arm. Several high-pressure nozzles are evenly installed on the high-pressure water pipe. The connecting plate is connected to the high-pressure nozzle, and the baffle plate is obliquely fixed to the end of the connecting plate away from the high-pressure nozzle.

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] 1) In the descaling mechanism, high-pressure water enters the high-pressure nozzle through the high-pressure water pipe and is sprayed onto the surface of the nickel-copper alloy plate, thereby impacting the broken oxide scale and further removing the oxide scale; the baffle plate can prevent high-pressure water from splashing; the electric push rod I provides power to drive the high-pressure water pipe to rotate through the baffle plate and connecting plate, thereby adjusting the spray angle of the high-pressure nozzle and improving the descaling efficiency.

[0014] 2) In the brushing mechanism, motor I provides power to drive the bidirectional threaded rod to rotate. The bidirectional threaded rod drives the lifting plate to move through the thread, and the lifting plate drives the cleaning brush to move, thereby adjusting the position of the cleaning brush and making the cleaning brushes on the pair of lifting plates staggered to prevent oxide scale residue on the surface of the nickel-copper alloy plate, while also reducing scratches on the surface of the nickel-copper alloy plate; motor II provides power to drive the cleaning brush to rotate through sprocket II, sprocket I and chain, thereby improving the oxide scale removal efficiency;

[0015] 3) It can clean the oxide scale on the surface of nickel-copper alloy through the cleaning and brushing mechanisms, preventing the oxide scale from being pressed into the surface of nickel-copper alloy again.

[0016] 4) In the adjustment mechanism, the electric push rod II provides power to drive the mounting plate to rotate around the rotating shaft, thereby causing the mounting plate to tilt the cleaning brush, so that the oxide scale that falls on the cleaning brush can slide off. At the same time, the electric push rod III provides power to drive the cleaning teeth to clean the bristles of the cleaning brush and prevent oxide scale from getting stuck on the cleaning brush.
