我国在铸铁热分析法预报化学成分方面的研究己经接近国际水平,尤其是在传感器的研制方面是这样,但是在推广应用方面却存在很大差距。文章认为,这个现象的出现主要是两方面的原因造成的,一方面是同传感器的质量有关,另一方面则是使用不当。为了说明问题。本文不但在理论上给予了必要的阐述,而且还给出了大量试验数据,同时比较了国内外的水平,提出了一些改进措施,以期促进这项技术的发展。 China’s research on the chemical composition prediction of cast iron thermal analysis has been close to international standards, especially in the sensor development is the case, but there is a big gap in the promotion and application. The article believes that the appearance of this phenomenon is mainly caused by two reasons, on the one hand with the quality of the sensor, on the other hand is not used properly. To illustrate the problem. This paper not only gives necessary explanations in theory, but also gives a lot of experimental data, at the same time compares the level at home and abroad, and puts forward some improvement measures in order to promote the development of this technology.
