连铸坯低倍酸蚀方法及分析

Etching Test and Analysis on Macrostructure and Defect of Continuous Casting Slab

随着国内高附加值产品的开发,连铸坯的内在质量显著改善,为适应连铸工艺和改进,实验室连铸坯低倍检验除评定一般疏松、裂纹、偏析和气泡等缺陷外,还开始检测连铸坯铸态树枝晶结构。文章对连铸坯的各种检测方法进行了详细的分析和比较。

Slab quality has been improved outstandingly in recent years with exploitation of high technology addiction.To adapt technics of continuous casting slab and improvement dendritical shape of continuous casting slab begins to be detected except for macro etch test for defects,such as crack,loose,segregation and bubbles of continuous casting slab in laboratory.This paper analyzed and compared detailedly various Etch tests and detecting methods for continuous casting slab.
