概述钢中非金属夹杂物(以下简称夹杂物)综合鉴定是怎样提出来的呢?我们是现场的化验室,主要是解决工厂中出现的某些品种质量问题。例如,钢板分层,工厂要求我们鉴定分层中夹杂物和分析分层产生的原因。开始,我们取带有分层的金相试样进行鉴定,有的问题可以解决,有的问题夹杂物组成比较复杂就不能解决,因此,迫使我们采用化学法和X光法来配合,用这三种方法对夹杂物进行联合鉴定,我们把这种联合鉴定的方法叫做夹杂物的综合鉴定。 1.金相法: 用金相法进行夹杂物的研究有许多优点,夹杂物不受化学试剂或电流的影响,可以观察到夹杂物的大
Overview of non-metallic inclusions in steel (hereinafter referred to as inclusions) is how to put forward a comprehensive identification? We are the scene of the laboratory, mainly to solve some of the plant quality problems. For example, steel delamination, the factory asked us to identify inclusions in stratification and analyze the reasons for the stratification. In the beginning, we took a metallographic sample with a layer of stratification for identification. Some problems could be solved. Some problems could not be solved because of the complicated composition of the inclusions. Therefore, we forced to adopt the chemical method and the X-ray method to cooperate with this Three methods for joint identification of inclusions, we call this method of identification of inclusions integrated identification. 1. Metallography: Metallography method for the study of inclusions has many advantages, inclusions are not affected by chemical reagents or current can be observed in large inclusions
