Abstract
PURPOSE: To shorten the time requirement of a descaling process, by applying a descaling process to a hot rolled steel sheet after machining it with a specified condition.
CONSTITUTION: A hot rolled steel sheet 4 is fed to a rolling mill 1 and is rolled with 3W10% draft, then 2W4% surface strain and 0.5W3% average plastic elongation are then given to the sheet 4 by a stretch-bending machine 2 through a stretch- bending process. Thus processed steel sheet 4 is passed through a descaling apparatus 3 provided with a mechanical descaling apparatus 6 mounted with a brushing roll, etc., or a pickling tank 7; hereby, the steel sheet 4 is descaled. By said method, the time requirement of the descaling process is shortened.
