On September 17, 8 top experts in the industry led by Liu Jiaqi, academician of the Chinese Academy of Sciences, organized the SCQY Basalt Composite Technology Group's first tank kiln demonstration production line project review meeting for basalt continuous fiber. The experts at the meeting gave a high evaluation of the project through rigorous review and agreed that the production equipment, process technology, and product performance indicators of the project reached the international advanced level.
"SCQY's production line is a domestic initiative in the fields of raw material homogenization, equipment selection, 2400-hole slat wire drawing intelligent technology, etc., and has reached the international advanced level." said Liu Jiaqi, an academician of the Chinese Academy of Sciences, which marks SCQY's role in basalt fiber Breakthroughs and milestones have been made in industrial scientific research and market expansion.
Advanced equipment
Overcome the key technical bottleneck of the homogenization equipment of the molten body of the tank kiln
"After seeing the scene, I felt very shocked." Ye Guangdou, a professor at Sichuan University, believes that the project is very advanced in at least three aspects: the homogenization of raw materials has achieved a great breakthrough; the intelligent manufacturing equipment of basalt fiber tank kiln is original. The structural design of the tank kiln is very advanced, and the 2400-hole slat wire drawing used is the world's first; compared with domestic and foreign counterparts, the process has achieved a big leap, breaking the bottleneck of the homogenization equipment and key technology of the tank kiln melt.
The review team believes that the first set of continuous basalt fiber tank kiln melt database and mathematical model application equipment and technology have realized the new technology of intelligent control technology for basalt fiber tank kiln melt, making the full-bath rate of drawing more than 75% and the uniform fiber The degree of quality is excellent, the number of raw silk is stably controlled within ±3%, and the pass rate reaches 96.3%.
Leading technology
The industry's first high-energy pure oxygen top-burning technology
Professor Fei Wei of the Institute of Composite Materials of Chongqing Jiaotong University said that SCQY used independent innovation technology to design a new basalt fiber tank kiln, and pioneered high thermal energy and pure oxygen top firing technology to achieve a high-precision world level with a stable melt temperature of ±0.1°C. The drawing operation rate has reached an advanced level of 98%, which is energy-saving and environmentally friendly, providing effective technical support for the design, installation and commissioning of basalt fiber large tank kilns above 10,000 tons.
At present, the SCQY basalt continuous fiber tank kiln production line has "breakthroughs" in a number of key technologies, which have solved the long-term problem of the development of China's basalt fiber industry, and realized the homogenization, tank kilnization, standardization, intelligentization and greenness of basalt continuous fiber. Chemical and serialized production has pushed the basalt continuous fiber industry to a new milestone.
Process breakthrough
Raw material homogenization technology and 2400-hole wire drawing technology achieve double breakthroughs
Zeng Lingrong, president of China Building Materials Industry Planning Institute, believes that SCQY's 2400-hole slat wire drawing technology and raw material homogenization technology eliminate the defect of large variation coefficient of the chemical composition of a single basalt raw material, and ensure the stability and stability of the melting temperature of the kiln melt Homogenization has laid a solid foundation for the production of large tow basalt fibers.
It is understood that the current industry's common research is the 1200-hole wire drawing technology. The daily output of a 1200-hole slat plate is less than 0.6 tons, and a 2400-hole slat plate will produce more than 1.5 tons per day. In contrast, the 2400-hole slat wire drawing technology will effectively reduce the production cost, labor cost and energy consumption of the enterprise, and will also greatly increase the production efficiency.
