Title:
MAGNESIUM ALLOY COILED MATERIAL
Document Type and Number:
WIPO Patent Application WO/2012/008380
Kind Code:
A1
Abstract:
Provided are a magnesium alloy coiled material which is a coiled material formed by winding a long plate material composed of magnesium alloy, and the thickness unevenness of which is small throughout the length thereof, and a grinding method for the magnesium alloy coiled material, a grinding device for magnesium alloy and a magnesium alloy plate.
When the plate material (raw plate (100)) that is sent out from the magnesium alloy coiled material and runs is ground with a grinding belt (13), the thickness of the raw plate (100) at a plurality of places in the widthwise direction is measured with a thickness measuring device (forward sensor (31)), and the gap between a contact roll (11) and a billy roll (12) is adjusted and then ground so that the size of the gap in the widthwise direction is uneven. The grinding step enables the thickness unevenness of a grinding plate (1) in the widthwise direction to be made within 40 µm throughout the length of the grinding plate (1) after grinding.
