Abstract

PURPOSE: To descale with a high efficiency, and to obtain a sheet strip having an excellent surface condition, by immersing the high temperature strip coil afte hot rolling in water to cool the same and by subjecting the uncoiled strip coil to a mechanical treatment and a pickling treatment.
CONSTITUTION: A high temperature strip coil after hot rolling, in a coil form, is immersed in water and is cooled. After this water cooling, the scales of this coil 6 contain a residual FeO; this coil 6 is uncoiled from a coiler 15 and is subjected to a skin pass mill 20 by whose light rolling work the scale layer generates cracks. The strip is then passed through a brushing apparatus 22 for grinding off the scales. The strip is then passed through a pickling tahk 24 in order to completely remove the remaining scales with an acid soluting 25; after which, the strip is passed through a cleaning apparatus 26 for cleaning the strip surface. By the present descaling method, the loss of iron base is prevented, and the working time of the pickling treatment is shortened.
