The purposes of the study are to evaluate the lubricity and the anti-seisure property of O/W emulsion and to examine the effect of various additives and saponfication value on these properties in cold sheet rolling, using the simulation testing machine developed by the present auther. The lubricity is evaluated by the coefficient of friction (μ=T/P+α) and anti-seisure property is evaluated by maximum roll speed or maximum reduction in a non-metal pick up region. The results obtained are as follows : (1) In rolling oils with an oiliness agent, the rolling oil with stearic acid is excellent in the lubricity and the anti-seisure property. (2) In rolling oils with a EP-agent, the rolling oil with dialkylphosphite is excellent in the lubricity and anti-seisure property. (3) In rolling oils mixed mineral oil with fat, the break in the curves of coefficient of friction versus saponification value is recognized.
