*Technology/Project Introduction (Background, current situation, characteristics, etc.): The national basic industry silicon alloy produces a large amount of unorganized emission of waste flue gas and dust during the process of high-temperature smelting and reduction, polluting the atmosphere and polluting the environment. It is recycled through supporting environmental protection dust removal equipment. Due to dust removal equipment (machinery manufacturing industry) and environmental protection pollution control (non-standard industry) technical process and smelting (metallurgical industry) technical process and market industry application Obstacles and promotion and publicity in marginal disciplines such as civil engineering, inorganic powder chemicals, etc. have resulted in the inability of recycled smoke and dust to adapt to the use of various industries in the market. Smelting companies can only use landfill disposal of the recovered smoke and dust to solve the environmental problems after emission and recycling. The project is guided by market application technology and uses multiple patented technologies to support the transformation of smoke and dust into a new ultra-fine powder material to promote the comprehensive utilization of smelting waste resources.  

 Through the integration of smelting, environmental protection, machinery, and market disciplines and application technology development, the dust and smelting slag emitted by the smelting industry have been developed, and the new powder materials transformed from dust and dust have replaced the new powder materials ground with mechanical power in the market. The attribute of the market product is named Silica Fume  *Main technical indicators: SiO2 85-96%; average particle size:0.10um-0.225um; specific surface area: 22000m2/kg; activity index (28d) 125; 

*Current application status: Activated silica powder is used in high-speed rail projects "Reactive Powder Concrete Structural Products-Cable Trench Covers (RPC)" in major national key projects, and cable-stayed bridges "Concrete Steel Tubes" in high-speed rail projects; high-strength, high-performance and durable concrete structure "c60--c200"; offshore concrete in the Hong Kong-Zhuhai-Macao Bridge project; cement-based osmotic crystallization waterproofing materials, grouting materials, permeable concrete floors in the construction of national sponge cities, etc.; 

*Application prospects of "civilian joining the army" or "military conversion" : The company adopts the model of technical development, technical services, technical consultation, and technology transfer for the comprehensive utilization of professional and special smelting waste resources in the environmental protection industry. Due to the national defense basic concrete engineering project, industrial and civilian construction standards are adopted to maintain the compressive strength of concrete relatively low, military projects are confidential, and the raw material organization to form basic engineering projects is lacking. With the application of high-strength, high-performance and durable concrete in the industrial and civilian construction market, Promote the transformation of national defense concrete engineering projects into the direction of high strength and durability, and form "activated silica powder" and "mineral admixture" that have good and extensive application prospects in military engineering projects.
