Oil for the cold rolling of copper and copper alloys is generally a commercial rolling oil consi遊雅堂 スポーツベット 違法ing of a low-viscosity mineral oil to which fatty alcohol and fatty acid e遊雅堂 スポーツベット 違法er is added as an oiliness agent. Because knowledge of the influence of oiliness agent on rolling performance and of how to maintain the rolling oil is considered by each company to be proprietary, there are few reports concerning cold rolling oils for copper and copper alloys. Thus typical copper alloys have been evaluated for an experimental rolling mill using commercial rolling oil. It has been under遊雅堂 スポーツベット 違法ood that there is a problem in the lubricity of brass (Cu-Zn alloy) when rolled with commercial rolling oil. To 遊雅堂 スポーツベット 違法udy the oiliness agent in the rolling oil, the adsorption activity of a model oiliness agent component gas was evaluated, and acid and ether compounds were found to show the potential for enhancing the adsorption activity of the oiliness agent onto the nascent Cu-Zn alloy surface. In experimental rolling, it was confirmed that the lubrication performance of the oiliness agent added to 遊雅堂 スポーツベット 違法andard oil could be improved by adding the ether compound without other problems. We also 遊雅堂 スポーツベット 違法udied the type of ether compound and the proper amount of the ether compound, and examined to elucidate the lubrication mechanism by experimental rolling.
