Abstract

The invention relates to a corroding agent for dendritic corrosion macroscopic examination, and belongs to the technical field of chemical analysis. Various components in the corroding agent orderly comprise the followings according to mass percent: 0.01%-1.0% of copper chloride, 0.01%-1.5% of copper nitrate, 0.01%-1.5% of magnesium chloride, 0.01%-3.0% of ferric chloride, 0.01-2.0% of ferrous chloride, 1.0%-4.0% of hydrochloric acid, 40%-50% of absolute ethyl alcohol, and the rest of water. Through the above technical scheme, the components of the corroding agent are optimally selected, and the detection range on the black metal variety is improved. The invention further relates to an effluent treatment system for the corroding agent, a fume cupboard is designed in mating for a problem that the hydrochloric can escape to the air in the corrosion since the hydrochloric concentration in the corroding agent is high, the hydrochloric acid in the air in the corrosion process is extracted,thereby preventing the hydrochloric acid from injuring respiratory tract of an operator; and meanwhile, the waste acid produced in the corrosion process is centrally collected through an integrated treatment box, thereby facilitating the waste acid treatment.

Description

technical field

[0001] The invention relates to a corrosive agent used for low-magnification inspection of dendrite corrosion and a waste liquid treatment system used for the corrosive agent, belonging to the technical field of chemical analysis and detection. Background technique

[0002] The low-magnification inspection method of dendritic corrosion is a low-magnification inspection method for continuous casting slabs that is becoming more and more perfect with the development of continuous casting technology. Compared with traditional low-magnification inspection methods such as sulfur printing and hot acid etching, it can not only accurately display the internal defects of continuous casting slabs, but also clearly display the solidification structure of continuous casting slabs. This creates favorable conditions for further analyzing the relevant information between the defects of the continuous casting slab and the solidification structure, and exploring ways and measu...
