Method for detecting concentration of emulsified liquid for aluminum hot rolling

The invention discloses a method for detecting the concentration of emulsified liquid for aluminum hot rolling, which comprises the following steps of: adding solid NaCl and dilute sulphuric acid intoan emulsified liquid sample to be detected to separate oil from water, and obtaining the oil content of the emulsified liquid according to the height of an oil layer by using a Babcock bottle as a measuring device, namely obtaining the concentration of the emulsified liquid. The method for detecting the concentration of the emulsified liquid is accurate and rapid in measurement, and can provide guidance for field production in time. 本发明公开了一种铝热轧用乳化液浓度的检测方法，其是通过在待测乳化液样品中添加固体NaCl和稀硫酸以使油水分离，并利用巴布可克瓶为测定装置，从而通过油层的高度而获得乳化液的含油量，即得到乳化液浓度。按本发明方法检测乳化液浓度，其测定准确、快速，能及时为现场生产提供指导。
