Description

Technical Field

[0001] This utility model belongs to the field of hot rolling technology, and specifically relates to an oxide scale rinsing device before roughing of N06625 nickel-based alloy hot continuous rolling. Background Technology

[0002] N06625 nickel-based alloy is a solid solution strengthened nickel-based alloy composed of elements such as nickel, chromium, iron, molybdenum, and cobalt. It possesses excellent corrosion resistance, high-temperature strength, high-temperature mechanical properties, coarsening properties, and high oxidation resistance, and is widely used in high-end fields such as aerospace, petrochemicals, and nuclear industry. However, during the process of transporting the N06625 nickel-based alloy slab, heated in the furnace, into the roughing mill, the high-temperature slab comes into contact with outside air, causing oxide scale to form on its surface. This oxide scale may 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 into the alloy during rolling, reducing its corrosion resistance and mechanical properties. Therefore, it is necessary to clean the oxide scale from the surface of the N06625 nickel-based alloy slab before roughing.

[0003] A search revealed a descaling device and hot-rolled strip steel production equipment with existing technology announcement number CN221848222U. This device controls the spraying pressure and flow rate of the first spraying component to clean the oxide scale on the surface of the steel billet by adjusting the component. At the same time, by adjusting the component to increase the spraying pressure and flow rate of the first spraying component corresponding to the middle of the steel billet, the cooling rate of the middle of the steel billet can be increased, thereby ensuring that there is no excessive temperature difference in various parts of the steel billet. However, this device cannot clean the oxide scale on the side of the steel billet, causing the residual oxide scale to follow the steel billet into the roughing mill and be pressed into the surface of the steel billet, affecting the rolled plate shape and dimensional accuracy, and may even cause problems such as tailing during the rolling process.

[0004] A search revealed a novel descaling device for rough-rolled slabs with the existing technology announcement number CN220461755U. This device cleans the upper surface of the slab by spraying high-pressure water and air through a spray branch pipe, while a high-pressure nozzle on the spray end pipe is aimed at the upper side wall of the slab to spray high-pressure water and air vertically to clean the oxide scale on the side of the slab. However, the edges of the slab are subject to bidirectional heat dissipation. Therefore, under the action of high-pressure water and air, the temperature difference between the upper edges of the slab and other parts of the slab is greater. This results in lower metal fluidity at the edges compared to other parts of the slab, causing the metal elongation at the edges to differ from that of other parts of the slab. Under the influence of this difference in elongation, defects may appear on the edges of the rolled steel strip. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an oxide scale rinsing device before roughing of N06625 nickel-based alloy hot continuous rolling. This invention cleans the edges and upper and lower surfaces of the alloy slab separately by using an edge cleaning device and a plane cleaning device, thereby preventing the edges of the alloy slab from cooling down too quickly, which could lead to quality problems in the subsequent rolling process.
