Embodiment 1－4

[0021] Examples 1-4 illustrate the method of the present invention by taking galvanized sheet, aluminum-coated sheet, and galvanized magnesium-aluminum sheet as examples, but this method is applicable to steel sheets with other coatings. The produced test plate is made into a disc with a diameter of 60mm-100mm (it can also be made into a square sample with a side length of 60mm-100mm). Before testing, the surface coating of the plate sample is dissolved and removed by chemical reagents. The dosage of hexamethylenetetramine and concentrated hydrochloric acid is shown in Table 1. After the preparation of the chemical reagents is completed, put the plate sample into the prepared chemical reagent for dissolving the coating. When the bubbles on the surface of the sample disappear during the dissolution process, immediately put the sample Take it out from the reagent, rinse the surface of the sample with a large amount of alcohol, and immediately dry the liquid on the surface of the ...

Abstract

The invention discloses a method for detecting element enrichment on the surface of a plate steel base material, which comprises the following steps of detecting the content of alloy elements in the plate steel base material by using a glow spectrometer, and dissolving and removing a plating on the surface of a plate sample by using a chemical reagent before detection. The obtained enrichment rule of elements such as silicon and manganese on the surface of the steel base material of the galvanized / aluminized / galvanized aluminum-magnesium plate can reflect the enrichment state of elements such as silicon and manganese on the surface of the base material before the galvanized / aluminized / galvanized aluminum-magnesium plate is galvanized, the measurement method is simple, convenient and rapid, and the measured numerical value is accurate.

Description

technical field [0001] The invention belongs to the technical field of steel plate surface analysis, and in particular relates to a method for detecting element enrichment on the surface of a steel plate substrate. Background technique [0002] The enrichment of elements such as silicon and manganese on the surface of the annealed sheet will affect the coating scratch resistance, coatability, adhesion and other properties of the galvanized sheet. Therefore, how to detect the enrichment of elements such as silicon and manganese on the surface of the steel substrate of the galvanized sheet is very important. [0003] Some literatures only mention that the enrichment of silicon-manganese and other elements on the surface of dual-phase steel such as dew point, oxygen content, and hydrogen content have certain influences, and affect the coatability of the zinc layer of galvanized steel sheet, but they do not provide specific information on the effect of coating on the finished co...
