世界轧钢工业的进步主要集中在生产工艺流程的缩短和简化,近终形连铸连轧、轧材性能高品质化、品种规格多样化、控制管理的计算机和信息化,使轧钢生产转向质量型和低成本的轨道上。1轧钢生产工艺流程将更加紧凑,和达到铸轧一体化生产在20世纪,由于连铸特别是近终形连铸的发展,轧钢行业已经实现了淘汰初轧工序。薄带钢连铸将使连铸与热轧工序合二为一,从而取消板带材生产的热轧工序,将连铸的薄带钢直接进入冷轧。目前多种形式的薄板坯连铸连轧生产和棒、线材的“黑匣子”连铸连轧生产已经实质上淘汰了加热工序,只配置直通式的补热(均热)炉。
The progress of the world rolling steel industry mainly focuses on the shortening and simplification of the production process, the near-net-shape continuous casting and rolling, the high quality of rolled products, the diversification of variety specifications, the computerized control and informationization, and the shift from rolled steel production to quality type And on the low cost track. 1 Rolling production process will be more compact, and to achieve integrated production of casting and rolling In the 20th century, due to the continuous casting, especially the near-continuous casting of the development, the rolling industry has achieved the elimination of the first rolling process. Strip casting will be continuous casting and hot rolling process into one, thus eliminating the strip hot strip production process, the continuous casting of thin strip steel directly into the cold-rolled. At present, various forms of thin slab continuous casting and rolling production and the production of rods and wires of “black box” and continuous casting and rolling have virtually eliminated the heating process and only the straight-through regenerative (soaking) furnace is equipped.
