The invention provides a rolling method and device for headless continuous casted and rolled ultra-low
carbon steel roll ferrite used for ultra-
deep drawing, and belongs to the field of metallurgicalrolling. The process of the rolling method is
continuous casting for billet forming,
high pressure water descaling, coarse rolling through a coarse rolling
machine set, rapid cooling (controlling
phase change),
high pressure water descaling, ferrite rolling through a fine rolling
machine set (blowing and sweeping water between racks), cooling through a layer cooling device, high speed flying shearfor
roll slitting and coiling through a coiling
machine. By means of the rolling method, the difficult problems that the
heating temperature of a
heating furnace before coarse rolling in a conventional hot rolling process is high, the time of temperature waiting for
cooling time between coarse rolling in an
Austenite area and fine rolling in a ferrite area is long, and the fine rolling temperature, the steel coil surface quality, forming performance and the like of
continuous casting and rolling process of a thin plate which is represented by CSP are difficult to stably control are solved, the rolling method has the advantages of being compact in
layout, few in investment, high in production efficiency, safe, reliable, energy-saving, environmental-protection, low in cost and the like, andthe ultra-low
carbon steel coil for ultra-
deep drawing is produced through headless
continuous casting and rolling and ferrite rolling.
