A kind of semi-automatic pickling method of low magnification test piece

Abstract

The invention belongs to the field of detection of metallographic low power test blocks, and particularly relates to a low power test block semi-automatic pickling method. The method comprises the following steps that firstly, acid liquid is preheated in an automatic pickling bath, and temperature and etching time are set; secondly, test blocks are put into the pickling bath according to the etching degrees; thirdly, the test blocks are subjected to automatic pickling is conducted according to the set temperature and time, after the set picking time is reached, the automatic pickling bath discharges acid automatically, a fan operates at a rated maximum rotation speed, and after acid mist in the bath disappears, a pickling bath cover is automatically opened for lifting-out operation on a pallet; fourthly, the test block pallet is lifted into a cleaning pool, and test block automatic cleaning is conducted by operating a cleaning trolley travelling button; and fifthly, the test block pallet is lifted out, enters a drying device with set drying temperature and reaches a detection zone until detection is completed. The low power test block semi-automatic pickling method is capable of relieving the labor intensity, ensuring the safety of operators and improving and increasing the surface quality of the test blocks after pickling.

Description

technical field [0001] The invention belongs to the detection field of metallographic low-magnification test pieces, in particular to a semi-automatic pickling method for low-magnification test pieces. Background technique [0002] The low-power pickling test of the metallographic test piece is mainly used to detect the macroscopic defects of the cross-section after cutting and processing forging billets, continuous casting billets or rolling billets, etc., and can detect the defect types of various billets Draw macro conclusions to facilitate the improvement of process and product quality. [0003] In the past, the pickling low-magnification detection was all carried out manually. About 30-50 pieces of test pieces with a thickness of 15-35mm and 100-300mm were tested every day. First, the test pieces were moved into the pickling pool manually, and then hot acid After the pickling time is up, manually remove the test pieces one by one from the acid solution in the acid pool...
