Description

technical field

[0001] The invention relates to a thermal acid etching device for low-magnification structure of steel, in particular to a thermal acid etching device adopting electromagnetic induction heating, and belongs to the technical field of metal processing. Background technique

[0002] Steel low-magnification structural defect inspection is also called macroscopic inspection, which can reflect the shape and distribution characteristics of microstructure and defects in the metal macroscopic area, and is an important steel quality inspection method. Steel low-magnification structural defect inspection includes hot acid etching test, sulfur printing test, phosphor printing inspection, etc., among which hot acid etching test is the most widely used. The hot acid etching test of the low-magnification structure of steel is generally carried out in the hot acid etching device, and the defects are observed after the hot acid etching of the steel by heating the acid solutio...
