With its clean, efficient and innovative advantages, new energy vehicles are rapidly becoming an important force in the global transportation field, becoming the first choice for urban transportation and personal travel, not only in the urban junction lanes everywhere, but also gradually into rural and remote areas, which significantly increased the proportion of green travel, leading the green revolution in the transportation industry.

In the production process of new energy vehicles, its own manufacturing link does not produce nitrogen oxide emissions, nitrogen oxide (NOx) is usually related to the high-temperature oxidation reaction in the combustion process, mainly applicable to the process of fossil fuel combustion, such as thermal power generation, industrial combustion and other processes and the operation of internal combustion engines. The production of new energy vehicles, such as body manufacturing, battery assembly, these do not directly involve the combustion process that produces nitrogen oxide emissions, however, the production of new energy vehicles, the raw materials used, such as steelmaking, hot rolling, cold rolling process in steel mills, especially the hot processing process of high-strength steel, may produce a certain amount of nitrogen oxides (NOx). The production of nitrogen oxides is mainly due to the heat treatment process of steel at high temperatures. During the high temperature heating process, nitrogen and oxygen elements on the surface of steel may combine to produce nitrogen oxides. Nitrogen oxide emissions are usually controlled and reduced in steel plants by installing denitrification equipment (SCR denitrification technology).

New energy vehicles in the manufacturing process, will need to use non-oriented silicon steel, non-oriented silicon steel is an important soft magnetic material, mainly used in the drive motor of new energy vehicles, it plays an important role in improving the efficiency of the motor and reducing carbon emissions. With the rapid development of the new energy automobile industry, especially the manufacturers of drive motors, the demand for non-oriented silicon steel continues to increase, and non-silicon steel has become the preferred material for manufacturing motor core because of its excellent magnetic properties. The production process of non-oriented silicon steel, especially the hot rolling stage, involves high temperature heating and fuel combustion, which produce nitrogen oxides (NOx). In order to effectively control and reduce the emission of pollutants, steel enterprises choose SCR denitrification technology to achieve environmental protection goals.

SCR denitrification technology of Guangdong Green Valley Environmental Protection Technology Co., Ltd. reduces NOx to harmless nitrogen (N₂) and water H₂O under a certain temperature and catalysis, so as to effectively reduce the emission of NOx. This technology is particularly important in sintering, pelleting, coking and other processes in the steel industry. SCR denitrification technology can meet the flue gas treatment of steel production, effectively reduce NOx emissions, achieve clean and environmentally friendly production, and meet environmental protection standards and sustainable development goals.
