Embodiment
[0014] When the copper product grade is TFE0.1 and the batch number is 0661032 strip, the thickness of the entrance is 14.0mm, and the thickness of the exit is 1.5mm, and the rolling is completed in 7 rolling passes. It is made by mixing 11% of 32# general-purpose engine oil, 55% of 7# general-purpose engine oil, 8% of sodium petroleum sulfonate, 11% of emulsifier, and 7% of white oil. In the preparation of lubricating fluid, first add 7# general-purpose motor oil to 32# general-purpose motor oil; then add sodium petroleum xanthate; then add emulsifier; then add 15# white oil; keep stirring and heating during the preparation. The temperature is controlled between 30°C and 50°C; according to the rolling conditions, add 95% deionized water and keep stirring and heating, the heating temperature is controlled between 30°C and 50°C, and finally formulated into a certain concentration of emulsified liquid for rolling. From the first rolling pass to the finished product, the emulsio...
