SHAPE CORRECTION METHOD FOR A ROLLED MAGNESIUM SHEET, WHICH PARTIALLY COOLS A ROLLED MAGNESIUM SHEET WHILE APPLYING TENSION TO ROLLS

摘要

PURPOSE: A shape correction method for a rolled magnesium sheet is provided to remove deformity, such as wave, pocket, corrugation, and bending, occurred in a rolled magnesium sheet due to temperature difference of rolling rolls or foreign materials.;CONSTITUTION: A shape correction method for a rolled magnesium sheet comprises the steps of: rolling a magnesium alloy panel to form a rolled magnesium alloy sheet of 270~300°C, winding the rolled magnesium alloy sheet around first and second rolls(10,20) and rotating the first and second rolls in the same direction to apply tension, and lowering the temperature of a part of the rolled magnesium alloy sheet to 90~120°C using a cooler(30).;COPYRIGHT KIPO 2010
