AI Technical Summary
Existing technologies have failed to effectively solve the problem of serrated edges in hot-rolled copper-containing steel, especially due to insufficient control over the matching of slab heating effect and rolling stability throughout the entire process.
The process employs long nozzle protection casting, hot charging rolling, five-stage heating in a walking beam furnace, reducing atmosphere in the furnace, multi-hole walking beam, and high-pressure descaling water purging, optimizing the entire process control, including slab continuous casting, heating, and rolling, to ensure temperature uniformity and stability.
It effectively suppressed the serrated edge defect of hot-rolled copper-containing steel, improved the surface quality of slabs and hot-rolled edges, and ensured the stability of rolling production and product qualification rate.
