Description

Technical Field

[0001] The invention relates to the technical field of hot rolling mills, in particular to an integrated device for primary hot rolling and coiling of nickel ingots. Background Art

[0002] Nickel ingots are block or ingot products made of nickel metal. Nickel is a silvery-white metal with good ductility and plasticity. It can be easily processed into various shapes and sizes and is widely used in aerospace, electronics, and steel industries. When reproducing and processing nickel ingots, the nickel ingots are usually placed in a heating furnace and heated to a temperature higher than their recrystallization temperature. The heated nickel ingots are then sent to a hot rolling mill. Through a series of continuous rolling rollers, their thickness is gradually reduced and their length and width are increased. However, existing hot rolling mills still have certain deficiencies when used.

[0003] For example, a stainless steel coil hot rolling device with publication number CN218798211U drives the hot rolling roller to rotate through the first driving motor, and performs hot rolling operation through the cooperation of the hot rolling roller and the support plate. At the same time, the hot rolling roller drives two rotating rods to rotate through meshing, and the two rotating rods can clean the surface of the stainless steel coil through two layers of cleaning steel brushes. At the same time, the second driving motor drives the fan blades to rotate, and the fan blades blow wind to blow off the impurities scraped off the surface of the stainless steel coil, thereby completing the cleaning of the surface of the stainless steel coil. However, it is usually necessary to heat the metal before hot rolling. Heat intensifies the thermal motion of atoms inside the metal and weakens the bonding force between atoms, thereby reducing the metal's deformation resistance and improving its plasticity. When metal reacts with oxygen in the air at high temperatures, an oxide layer will form on its surface, which will not only consume the metal itself, but may also affect the quality of subsequent processing. For example, during hot rolling, the oxide scale may fall off and embed into the metal to form defects. At the same time, the metal itself absorbs and stores a large amount of heat energy. However, before hot rolling, this heat energy often cannot be directly recycled, but is dissipated into the environment, which not only causes a waste of energy, but may also cause thermal pollution to the environment.

[0004] Therefore, we propose an integrated device for primary hot rolling and coiling of nickel ingots in order to solve the above-mentioned problems. Summary of the invention

[0026] Its use is as Figure 1-Figure 3 According to the technical solution shown, the shielding cover 11 is first fixedly placed above the frame 1 so that the positioning plate 7 is located inside the shielding cover 11, and then the electric push rod 5 is turned on to push the positioning plate 7 on the frame 1 so that the conveying roller 8 on the positioning plate 7 can just fit with the side wall of the nickel ingot to be hot-rolled, and then the conveying roller 6 is started to rotate so that the conveying roller 6 drives the nickel ingot to move, and the nickel ingot will enter the shielding cover 11 through the opening 16, so as to fit with the conveying roller 8, and at this time, the air pump and the driving motor 12 are turned on, and the air pump will convey the high-pressure gas to the connecting pipe 1001 through the pipeline, and then the connecting pipe 1001 will convey the high-pressure gas to the connecting pipe 1001.
