[0019] When rolling the copper grade in the middle is H65, when the batch number 5066011 brass strip, its entrance thickness is 1.8mm, and the exit thickness is 0.6mm, which is completed in 5 rolling passes; for this purpose, prepare 1000 kg of emulsion. First prepare emulsified oil by adding 10% of 32# general machine tool hydraulic oil to the container, then add 70% of 7# mechanical oil, 5% of sodium petroleum sulfonate, 10% of O-10 emulsifier, 5% of For 7# industrial white oil, use a stirrer to stir continuously and use an electric heater to control the temperature during the preparation. The stirring time is 60 minutes, and the heating temperature is 50°C. Then add the prepared emulsified oil into 90% deionized water, use a stirrer to continuously stir and dilute during the preparation, and insert an electric heater for temperature-controlled heating. The stirring time is 240 minutes, and the heating temperature is 50°C. It is prepared into an emulsion suitable for rolling...
