Problems solved by technology

At present, due to the lack of standard samples of silicon steel with similar smelting process and composition elements, the chemical analysis technology of high value-added products such as silicon steel in metallurgical iron and steel enterprises obviously cannot meet the requirements of process control. This situation largely restricts the development of new analysis methods. Research and development, the method development of many online detection methods and new equipment obviously lags behind the scientific research and production process

Description

technical field [0001] The invention belongs to the field of chemical analysis, in particular to a standard sample of low-carbon aluminum-containing silicon steel and a preparation method thereof. Background technique [0002] Cold-rolled electrical steel products are important metal functional materials, which are widely used in various fields of the national economy. They are one of the products with high-tech integration and the highest added value in iron and steel complexes. The cores of transformers and motors are made of silicon steel sheets with good performance. Not only can save energy, reduce iron loss, but also reduce noise pollution. [0003] The current production of silicon steel has two outstanding features: one is that the chemical composition of silicon steel is extremely strict; the other is that the production method has changed from hot rolling production before the 1960s to cold rolling production. [0004] Independent research and development of new m...
