A mosaic method suitable for products with a diameter or thickness less than 2mm

Abstract

The invention discloses a mosaic method suitable for products with a diameter or thickness less than 2mm, which specifically includes the following steps: (1) selecting a mosaic method according to product requirements, wherein the mosaic method includes hot mosaic and cold mosaic; Samples with a thickness less than 2mm are laid flat in the mounting machine for a single inlay, and the inlay depth reaches 4-8mm; (3) Cool the sample after the first inlay in step (2), and then use a cutting machine to cut it longitudinally, and cut it into a small sample for the second inlay (4) The small sample after the longitudinal section in step (3) is vertically inlaid for the second time to ensure the integrity of the product; (5) The sample after the second inlay is ground, polished and analyzed according to the preparation process used for metallography; the present invention It solves the problem of inlaying products with a diameter or thickness less than 2mm without a spring clamp, and at the same time solves the problem that the sample deflection often occurs during the traditional small sample inlaying process, resulting in the inability to accurately test and analyze. This inlaying method is simple and easy, and the accuracy of the inspection and analysis data 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
