Inlaying method for products having diameter or thickness less than 2mm

Abstract

The invention discloses an inlaying method for products having the diameter or thickness less than 2mm. The method comprises the following steps that: step one, an inlaying method is selected based ona product need, wherein the inlaying method includes thermal inlaying and cold inlaying; step two, a sample having the diameter or thickness less than 2mm is laid in an inlaying machine for primary inlaying, wherein the inlaying depth reaches 4 to 8mm; step three, after the primary inlaying in the step two, the sample is cooled and a cutting machine is used for cutting the sample longitudinally into small samples with secondary inlaying; step four, carrying out secondary inlaying vertically on the small samples obtained after longitudinal cutting in the step three to ensure the product integrity; and step five, the samples after secondary inlaying are ground, polished and analyzed based on a preparation flow used by metallographic phase. According to the invention, a problem of inlaying of a product having the diameter or thickness less than 2mm by a fixture without a spring and a problem that detection and analysis can not be carried out accurately due to test sample deviation duringthe traditional small sample inlaying process are solved. The inlaying method is simple and is easy to implement; and the data checking and analysis accuracy is high.

Description

technical field [0001] The invention relates to a practical inlay method for preparing cold and hot inlay samples in the iron and steel manufacturing industry. Specifically, it is suitable for internal structure, decarburization layer, and surface of products with a diameter or thickness less than 2mm without the need for spring clamps. A mosaic method for the analysis of defects, failures, etc. Background technique [0002] In the iron and steel manufacturing industry, the diversity of product shapes is the characteristic of the industry. How to analyze the surface and internal organization of products of different shapes is a test. The research department analyzes product performance and promotes product production process improvement. One of the necessary items. Therefore, for a long time, the manufacturing industry has been accustomed to irregular shapes, wires and plates, small workpieces, surface treatment and coating, surface decarburization material preparation (grin...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to solve the problem of inlaying a product with a diameter or thickness less than 2mm without a spring clamp, that is, the problem that the sample cannot be correctly analyzed for failure or the inspection and analysis of the surface and internal tissue structure; at the same time, it solves the problem of traditional In the process of inlaying small samples, the sample deflection often leads to the problem of inaccurate inspection and analysis, overcomes the shortcomings of the existing technology, and provides an inlay method suitable for products with a diameter or thickness less than 2mm. This inlay method is simple and easy to implement and low in cost. , high accuracy of inspection and analysis data
