The main components of silicon manganese nitride are accompanied by ferrosilicon nitride and ferromanganese nitride, as well as some other small amounts of mixed elements. The resulting silicon manganese nitride is an off-white product. Silicon manganese nitride is mainly used as a nitrogen-increasing agent for oriented silicon steel, as a nitrogen-increasing agent for high-strength steel, and also as a nitrogen-increasing agent for casting. Domestically, silicon manganese nitride is mainly used to increase the nitrogen content of oriented silicon steel. The invention of using silicon manganese nitride to increase nitrogen in molten steel was invented in 2007. The reason for considering the application at that time was that the manganese nitride was more easily decomposed into molten steel for absorption. That is to say, at the same molten steel temperature, the nitrogen recovery rate of manganese nitride was The single silicon nitride may be higher, and the oriented silicon steel has certain restrictions on manganese. Therefore, it is proposed to use silicon manganese nitride to achieve the double effect of improving nitrogen recovery without increasing too much manganese. Using silicon manganese nitride as orientation silicon steel to increase nitrogen compared with ferro silicon nitride with similar nitrogen content, the recovery rate of nitrogen is high, and the fluctuation range of molten steel is small. After nearly four years of use, all silicon nitride manganese for smelting oriented silicon steel Increase nitrogen.
Ningxia Zhonghong Nitriding Products Co., Ltd. was founded in 2003. It is a joint-stock company specializing in the development, design, production and sales of nitrided products. The headquarters and production park are located in the development zone of Desheng Industrial Park in Yinchuan, with the Helan Mountain in the west, the Yellow River in the east, the Beijing-Tibet Expressway in the east, and the 109 National Line running through the north and south. The company covers an area of 26666 square meters.
The company has 85 employees and 30 professional and technical personnel. It has many years of experience in nitride research and production, and has unique advantages in vacuum smelting technology and production equipment. Adopting international advanced technology in product research and development, independent development and design after absorption and digestion, products and production processes have reached the advanced level at home and abroad, and won the autonomous region high-tech product certification and Yinchuan City Science and Technology Innovation Award. In 2005, it was rated as the most potential development project enterprise in Yinchuan City. Take the lead in passing the ISO9001 quality system certification. In 2009, it was rated as AA++ enterprise of Ningxia Bank. The product production process adopts the requirements of clean production, strives for the concept of green environmental protection, and reaches the environmentally friendly zero emission standard.
The company's products are: ferrosilicon nitride, silicon nitride, silicon manganese nitride, alum nitride, aluminum nitride and other high-performance nitrides.
