Abstract

An electrochemical method and device for sorting structural steel grades. The main purpose is to provide an electrochemical method capable of quickly and accurately sorting structural steel grades and a device for realizing the method. It is characterized in that: the main step of the method is to measure and obtain the anodic polarization curve of the unknown brand structural steel in a special electrolyte solution by performing electrochemical experiments on the structural steel of the unknown brand, and analyze the characteristic parameters of the anodic polarization curve, and then Compared and identified with the standard anodic polarization curve characteristic parameters of known grades of structural steel in the standard sample database, the grade of the steel is finally identified; the device includes an electrochemical test module and a polarization curve identification module; the electrochemical The test module includes a three-electrode electrolytic cell, a test circuit and a motor stirring circuit; the polarization curve identification module includes an 89C51 chip, an analog-to-digital conversion chip and a liquid crystal display circuit.

Description

technical field [0001] The invention relates to a method and device for determining the designation of structural steel. Background technique [0002] In the process of production and scientific research, the phenomenon of confusion of raw material structural steel grades often occurs, and the phenomenon of mixing materials will cause serious engineering quality accidents and failure of scientific experiments. Therefore, factories and universities often need to sort the grades of raw structural steel. In the past, the sorting of raw material structural steel grades mainly used methods such as spectrometry, looking at the sparks from the grinding wheel, and eddy current detection signals. These methods are inseparable from the accumulation of operator experience. At the same time, it is difficult to automate the raw material sorting process. Contents of the invention [0003] In order to solve the technical problems mentioned in the background technology, the present invent...
