Title: Manufacturing method of aluminum alloy sheet
Inventor: ANDO HIROYUKI
IPC: B21B1/22
Filed: 2001-03-30
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of an aluminum alloy sheet capable of preventing surface defects caused by abrasive powder without resulting in increase of processing steps. SOLUTION: When processing rate is relatively high, the heat generation due to the process increases that much. As a result, as shown in (a), rolling oil fed onto an aluminum alloy sheet stock 1 is lost by the evaporation and the aluminum alloy sheet stock and the abrasive powder bind together mutually by means of the intermolecular attractive force. On the other hand, when the processing rate is relatively low, the heat generation due to the process decreases that much, the rolling oil 3 leaves on the surface of the aluminum alloy sheet stock 1 even in the rolling outlet side, as shown in (b), the rolling oil 3 is interposed between the abrasive powder 2 and the aluminum alloy sheet stock 1.  When these are cleaned in the same condition, as the adhesion by the surface tension is extremely weak as compared with the bond by the intermolecular attraction, the abrasive powder stuck by the surface tension as shown in (b), is easily removed.
