制备一种新型铝热连轧乳化液，其采用复合乳化剂以形成较稳定的乳化液体系，从而减少轧制油耗，改善轧件表面退火清洁性及保证乳化液的使用寿命；同时辅以高效极压剂以弥补稳定型乳化液润滑性能不足的缺点。通过单机架多道次模拟热连轧条件下润滑实验，研究新型乳化液对铝板热轧过程轧制力和终轧厚度的影响，并考察乳化液的稳定性和铺展能力。结果表明：新型乳化液具有优良的轧制润滑效果，相比传统商品乳化液轧制力降低了5�2％～16�9％，终轧厚度减小了4�8％～10�6％；新型乳化液具有良好的稳定性、热分离性和铺展能力，可改善轧后铝板表面清洁性。%A new emulsionfor aluminum strip was prepared by using the compound emulsifier to form a stable emulsion system, in order to reduce oil consumption, improve rolled surface quality and ensure the service life. An efficient extreme pressure agent was mixed with the new emulsion to make up for the lack of lubrication performances of a stable emulsion. The effect on the rolling force and final rolling thickness by the new emulsions for aluminum hot rolling was studied by lu⁃brication experiments to simulate continuous rolling with single stand and multi⁃pass rolling. The stability and wettability of the new emulsion was also observed. Compared with the traditional commercial emulsion, the new emulsion decreases the rolling force by 5�2%-16�9%, and the rolling thickness by 4�8%-10�6%. The new emulsion shows good stability, heat decomposability and wettability, which can improve the rolled surface quality.
