Abstract

The invention discloses a method for detecting fish scaling resistance of a hot-rolled pickled enameled steel plate, and mainly solves the technical problem that the fish scaling resistance of an existing hot-rolled pickled enameled steel plate cannot be accurately detected. The invention discloses a method for detecting fish scaling resistance of a hot-rolled pickled enameled steel plate, which comprises the following steps that: (1) a sample is prepared; (2) the sample is coated with enamel glaze through a wet coating method, the surface of the sample is coated with colloidal enamel glaze, the thickness of the colloidal enamel glaze applied in each pass is 0.05-0.10 mm, the thicknesses of enamel glaze layers on one side surface and four cross sections of the sample are controlled to be 0.30-0.35 mm, and the thickness of the enamel glaze layer on the surface of the other side of the sample is controlled to be 0.10-0.20 mm; (3) enameling treatment is carried out on the sample; and (4) the fish scaling resistance of the hot-rolled pickled enameled steel plate is evaluated. The method is high in detection efficiency, high in detection precision and low in detection cost.

Description

technical field [0001] The invention relates to a detection method for the performance of a hot-rolled pickled enamel steel plate, in particular to a detection method for the scale explosion resistance of a hot-rolled pickled enamel steel plate, which belongs to the field of steel material performance testing. Background technique [0002] Enamel has the advantages of easy cleaning, corrosion resistance, environmental protection, etc., and is widely used in light industry, home appliances, construction engineering, metallurgy, chemical industry, etc., from kitchen utensils, sanitary ware, barbecue ovens, to water heater inner tanks, subway decorative panels , Chemical reaction tanks, all have enamel. [0003] According to the production process, steel plates for enamelling can be divided into hot-rolled pickling enamelled steel, cold-rolled enameled steel and cladding enameled steel. Among them, the hot-rolled pickling plate has high strength before and after enamelling, go...
