Abstract

The invention relates to grinding paste for processing dendrite macroscopic examination samples and a preparation method of the grinding paste, and solves the technical problems that conventional grinding paste cannot meet requirement that the surface roughness Ra of dendrite macroscopic examination billet samples of different steel kinds is smaller than or equal to 0.1[mu]m, and the production cost is high. The grinding paste for processing the dendrite macroscopic examination samples is prepared from 35-60 parts of green silicon carbide grinding powder, 25-35 parts of a lubricant and 15-35 parts of a grinding aid, wherein the lubricant is lithium lubricating grease, and the grinding aid is toothpaste. The grinding paste disclosed by the invention is used for performing polishing processing on the steel strand dendrite macroscopic examination samples.

Description

[0001] technical field [0002] The invention relates to the technical field of grinding paste, in particular to a grinding paste for dendritic low-magnification inspection sample processing and a preparation method thereof. [0003] Background technique [0004] Low-magnification inspection is the main means to judge the quality of continuous casting slabs. Iron and steel enterprises often use low-magnification inspection methods to detect internal quality defects after continuous casting slabs solidify. Commonly used low-magnification inspection methods include sulfur stamp inspection, hot acid corrosion, and cold acid corrosion. Corrosion, electrolytic corrosion and dendrite inspection; Compared with other low-magnification inspection methods, dendrite inspection can accurately display the internal defects of continuous casting slabs, and clearly display the solidification structure of continuous casting slabs. Proportionality shows that it does not expand or narrow the ...
