Problems solved by technology

[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; The particle size increases, the ESI value decreases, the stability and lubricity of the emulsion are reduced, the residue on the rolling plate surface increases, the consumption of the emulsion is increased, and the surface defects are more likely to occur after the emulsion is dirty

Embodiment Construction

[0036] The present invention mainly utilizes the existing resources to formulate a method for measuring the acid-insoluble ash content of the hot-rolled aluminum emulsion. Excessive pollution affects the surface quality of aluminum hot rolling.

[0037] The main steps and contents of the method are as follows:

[0038] 1. Instruments and reagents: porcelain crucible-50mL or 100mL, analytical balance-accurate to 0.0001g, universal electric furnace (2000W, adjustable temperature), muffle furnace-capable of constant temperature at 800°C, desiccator (without desiccant) , glass funnel 80mL, quantitative filter paper-φ9cm medium speed, quantitative filter paper-φ12.5cm medium speed, dilute hydrochloric acid 5%, dilute hydrochloric acid 1:4

[0039] 2. Preparation

[0040] 2.1. Immerse a 50mL porcelain crucible in a beaker filled with dilute hydrochloric acid (1:4), boil it for 10 minutes, take it out, wash it with distilled water 2-3 times, put it into a muffle furnace after dryin...

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...
