It is understood that Lanfeng Technology, a subsidiary of Kailong High-tech (300912), has recently developed recrystallized silicon carbide products with high technical content, and achieved industrialization demonstration, filling the gap in domestic recrystallized silicon carbide products.

　　The non-road "National IV" emission standards implemented at the end of 2022 have added a fire to the sales of post-treatment products for spring farming machinery this year, and the company's post-treatment products are in short supply. In order to expand the production capacity of silicon carbide carrier, the company has purchased six new kilns of 5 cubic meters, which will further meet the increasing production needs of the company.

　　Up to now, the company's non-road mobile machinery country 4 project has completed 10 announcement certification, has built a production line that meets the emission standards of non-road mobile machinery Country 4, and has a stable market share.

　　The data show that recrystallized silicon carbide (R-SiC) is a high-performance material formed at a high temperature above 2000 ° C and the hardness is second only to diamond. It retains many excellent properties of SiC, such as high temperature strength, strong corrosion resistance, excellent oxidation resistance, good thermal shock resistance and so on. Data show that the silicon carbide market size of one trillion US dollars, mainly used in automotive environmental protection, waste water treatment, semiconductor, light industry, national defense military, petroleum industry, chemical industry, nuclear technology and laser and other fields.

　　It is understood that in the first quarter, as the economy continued to recover, large-scale infrastructure projects around the country began one after another, and orders were full; The company said that the technological breakthrough and production expansion of the silicon carbide project is conducive to further establishing the production process and technical specifications of the carrier and catalyst, forming a diesel vehicle particle control technology with complete independent intellectual property rights, and completing the industrialization demonstration. It can not only break the technical blockade of foreign countries, but also provide practical technology and product support for the current diesel engine industry in China to achieve emission upgrading, and consolidate the company's leading position in the industry.
