新时代10年我国电工钢及20辊轧机发展研究

Research on the development of electrical steel and 20-high rolling mill in China in the decade of the new era

新时代10年我国20辊轧机技术进步很快,关键部件有了突破性进展。为客观分析国产轧机这十年的发展情况,及与国外轧机的优劣势对比,重点介绍了国外20辊轧机在中国的应用情况、10年间我国电工钢产量和质量的变化及20辊轧机的发展情况,并对20辊轧机的主要特点及关键指标进行分析,同时就现阶段我国国产20辊轧机性能与进口同类机型进行了比较分析。

In the decade of the new era,China’s technology of 20-high rolling mills has made rapid progress,with breakthroughs in key components.In order to objectively analyze the development of domestic 20-high rolling mills in the past ten years and compare their advantages and disadvantages with those of foreign rolling mills,the application of foreign 20-high rolling mills in China,the changes of China’s output and quality of electrical steel and the development of domestic 20-high rolling mill in the past 10 years were mainly introduced in this paper.And the main characteristics and key indexes of the 20-high rolling mill were analyzed.Meanwhile,the properties of domestic 20-high rolling mills at present were compared with that of imported similar models.
