AI Technical Summary
Existing high-temperature alloy sheet production suffers from problems such as difficulty in controlling dimensional accuracy, poor surface quality, large quality fluctuations, high production difficulty, and high cost. In particular, it is difficult to meet the high-performance requirements of aerospace and nuclear power fields under the conditions of wide width and thin specifications.
The preparation method of large-coil, wide-width high-temperature alloy coils includes steps such as slab pretreatment, step-by-step hot rolling, solution treatment, surface treatment, cold rolling, and intermediate annealing. By optimizing the process flow and key process parameters, the uniformity of the internal structure and microstructure of the slab is ensured, defects such as cracks are reduced, and dimensional accuracy and surface quality are improved.
It has enabled the production of high-quality, high-dimensional precision high-temperature alloy plates with wider widths and thinner thicknesses, significantly improving production efficiency and material utilization, and meeting the high-performance and lightweight requirements of aerospace, nuclear power and other fields.
