New method for measuring hot rolling emulsion cleanliness

Abstract

The invention relates to a detection method. The method can effectively analyze the content of insoluble metal ions, non-metallic substances and the like in an emulsion use process. By analysis and contrast, the method provides reliable basis for sudden change of indexes in emulsion production and analysis and solution of emulsion caused surface defects.

Description

technical field [0001] The invention relates to a new method for measuring the cleanliness of hot-rolled emulsion, in particular, a method for detecting and measuring the cleanliness of the emulsion itself during aluminum rolling. Background technique [0002] The cleanliness of the emulsion during use has a great influence on the quality of the aluminum alloy rolling surface. The production environment of the hot rolling mill is relatively harsh, and metal oxides, ground sludge, and air dust will pollute the emulsion; As the particle size increases, the ESI value decreases, reducing the stability and lubricity of the emulsion, resulting in an increase in the residue on the rolling plate surface, increasing the consumption of the emulsion, and surface defects are more likely to occur after the emulsion is dirty. Seriously think and analyze according to actual needs, and use existing materials and testing equipment to invent a new method to measure the cleanliness of hot roll...
