Relationship of Oil Composition and Lubricating Characteristics in Cold Rolling Aluminum Strips
To explore the relationship of oil composition and lubricating characteristics, new base oils with different carbon chain length and aromatics contents for lubrication in cold rolling aluminum process were investigated by means of Gas Chromatography-Mass Spectrometry. Tribological tests were carried out on a four-ball friction and wear testing machine. Results showed that the film strength gradually increased with an increasing of aromatics content in oils and friction coefficients decreases simultaneously. Cold rolling experiments were conducted to be further to analyze the lubrication effects of new rolling oils by a 4-high mill. The curves of lubricating characteristics in rolling were obtained, and the minimum rolling thickness after rolling under different lubricating conditions was found to decrease obviously.
