Sinosteel Luoyang Refractory Research Institute Polycrystalline Fiber Industry Introduction
    Sinosteel Luoyang Refractory Research Institute Co., Ltd. (hereinafter referred to as Sinosteel Luonai Institute) is a unit that conducts research, development and production of polycrystalline alumina fibers in Neizao. Since the "Seventh Five-Year Plan", it has successively won many provincial and ministerial awards. In order to industrialize the scientific and technological achievements as soon as possible, in 2008, the second unit engaged in the scientific research and production of high-temperature refractory fibers-Polycrystalline Fiber Factory was established. 
   Through years of systematic research, major breakthroughs have been made in the scientific research and industrialization of polycrystalline fiber series products, which can produce polycrystalline alumina fiber series polycrystalline fiber cotton and its downstream products with an alumina content of 72%-95%. The product types are compared within, and the product quality is at an internal level. In particular, it successfully developed polycrystalline fiber products with a high use temperature of 1800°C and a long-term use temperature of 1700°C. And it has been verified in a number of long-term use of 1700℃ kilns, and the performance is equivalent to that of external products, successfully filling in the internal gap and reducing the cost of internal users.
