Abstract

The invention discloses a method for detecting the anti-scaling performance of hot-rolled and pickled enamel steel sheets, which mainly solves the technical problem that the anti-scaling performance of the existing hot-rolled and pickled enamel steel sheets cannot be accurately detected. The invention provides a method for detecting the anti-scaling performance of a hot-rolled acid-washed enamel steel plate, comprising: 1) preparing a sample; 2) coating the sample with enamel glaze by a wet coating method, and coating the surface of the sample with glue The thickness of the glue-like enamel glaze is 0.05~0.10mm for each pass, and the thickness of the enamel glaze layer on one side of the control sample and four sections is 0.30~0.35mm; the thickness of the control sample is 0.30~0.35mm. The thickness of the enamel glaze layer on the other side surface is 0.10-0.20 mm; 3) Enamel treatment is performed on the sample; 4) The anti-scalding performance of the hot-rolled acid-washed enamel steel plate is evaluated. The method of the invention has high detection efficiency, high detection precision and low detection cost.

Description

technical field [0001] The invention relates to a method for detecting the properties of a hot-rolled acid-washed enamel steel sheet, in particular to a method for detecting the anti-scaling performance of a hot-rolled acid-washed enamel steel sheet, which belongs to the field of performance testing of steel materials. Background technique [0002] Enamel has the advantages of easy cleaning, corrosion resistance, environmental protection, etc. It is widely used in light industry, home appliances, construction engineering, metallurgy, chemical industry, etc. , chemical reaction tanks, all have enamel. [0003] According to the production process, steel plates for enamel can be divided into hot-rolled pickled enamel steel, cold-rolled enamel steel and clad enamel steel. Among them, the hot-rolled pickling plate has high strength before and after enameling, good formability and good enameling performance. Recently, it has been widely used in water heater liner, etc. [0004] ...
