Estimating the term…
The device has a short production line, and all components are reasonably configured. A multifunctional cooling control device is adopted to integrate high-pressure water descaling and intermediate billet cooling functions, which is simpler and more efficient. Layout of a 4R+(3−4)F rolling mill, four thermos-detectors and short-distance underground coilers are use. The method includes the steps: carrying out continuous casting to manufacture a slab, high-pressure water rotating descaling, rough rolling by a four-stand high reduction rough rolling unit, machining by a drum shear, cooling after high-pressure water descaling in the multifunctional cooling control device, finish rolling by a three-stand or four-stand finish rolling unit, air cooling, dividing coils by a high-speed flying shear, and coiling by underground coilers, wherein temperature monitoring is respectively carried out after rough rolling, before finish rolling, after finish rolling, and before coiling by the underground coiler.
An endless hot-rolled strip production device for ferrite rolling, comprising a continuous casting machine, a high-pressure water rotating descaling device, a four-stand high reduction rough rolling unit, a drum shear, thermo-detectors, a multifunctional cooling control device, a three-stand or four-stand finish rolling unit, a high-speed flying shear, and underground coilers, wherein,
