Description

Technical Field

[0001] This utility model belongs to the field of hot rolling technology, and specifically relates to a laminar flow cooling device for N04400 nickel-copper alloy hot continuous rolling coil. Background Technology

[0002] N04400 nickel-copper alloy is mainly composed of nickel and copper. Due to its excellent thermal stability, corrosion resistance and outstanding strength, it is often used in chemical, marine engineering and aerospace fields. In the production process of N04400 nickel-copper alloy sheet and coil, laminar cooling can affect the microstructure of the alloy, release the stress generated during the hot rolling process of N04400 nickel-copper alloy sheet and coil, and improve the performance of N04400 nickel-copper alloy sheet and coil.

[0003] A search revealed a special built-in baffle laminar flow cooling manifold device with the existing technology announcement number CN 222058488 U. This device achieves flexible zoned adjustment of flow rate and pressure in the middle and edge regions through edge shielding. The middle region can cool the middle position of the metal plate according to the cooling rate and water volume set by the process. At the same time, by inputting cooling water at different pressures to the two edge regions or by introducing return water, the amount of cooling water sprayed onto the metal plate and the cooling rate of the metal plate can be controlled.

[0004] A search revealed a prior art announcement number CN 221773154 U for a strip laminar flow cooling upper manifold with uniform water output. This device ensures that the amount of cooling water sprayed onto the metal plate by each upper spray pipe is consistent by setting a throttling structure at each mounting slot of the upper spray pipe mounting body. Furthermore, when the water flows into the upper spray pipe, the hydraulic force drives the sealing structure to move upward, causing the blocking block to seal the drain hole, further ensuring that the upper spray pipe sprays cooling water uniformly.

[0005] However, the cooling water sprayed onto the middle of the metal plate by the above two devices will flow to the edge of the metal plate, causing the temperature of the edge of the metal plate to drop rapidly, resulting in quality problems of the metal plate. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a laminar flow cooling device for N04400 nickel-copper alloy hot-rolled plate coils. This invention recovers the cooling water sprayed onto the middle of the alloy plate by the laminar flow cooling manifold through a recovery device, preventing the cooling water from flowing to the edge of the alloy plate.

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] 1) The cooling water sprayed onto the middle of the alloy plate by the cooling water cleaning mechanism in the recycling device is recycled to prevent the cooling water from spreading to the edge of the alloy plate, which would cause uneven temperature distribution along the width of the alloy plate, resulting in performance differences in the width of the alloy plate and defects such as edge waviness.

[0016] 2) Controlling the rotation of the baffle in the water-blocking mechanism can expand the width of the cooling water intercepted by the recovery device, thus making it easier for the device to adapt to the processing of alloy plates of different widths. Attached Figure Description
