Major achievements, awards, contributions to production

Li Zhaoxia is a well-known expert in the field of refractory materials and industrial furnace lining design in China. She has been engaged in refractory research for nearly 50 years. During this period, she obtained 55 invention patents at home and abroad, presided over one national torch plan project in 2016 and one national key new product project. The "fluidized roasting high-efficiency energy-saving furnace technology" developed by her has been listed in the second batch of national key energy-saving promotion technology catalogue; the "energy-saving technology for combined lining of large rotary kiln" has been listed in the National Key Energy-saving and Low-carbon Technology Promotion Catalogue (this energy-saving part in 2016), and she won the 2017 Innovation Award for Applying New Technologies in Top Ten Industries in China. After years of hard work, she has summarized and created a total of 14 scientific and technological achievements (appraised by China Nonferrous Metals Industry Association and China High-tech Industrialization Research Association to reach the international advanced level), including Localization of Unshaped Refractories for Imported Metallurgical Furnaces Such as Flash Furnaces and Ausmelt Furnaces, New Lining Structure of Fluidized Roasting Furnace and Whole Casting Technology of Amorphous Refractories, Research on New Non-metallic Hanging Structure Composite Furnace Wall Structure and Application of New Materials at the Top Level of Circulating Fluidized Bed Boiler, Insulation Dry Packing of Inductor of Zinc Melting Power Frequency Electric Furnace (Cored) and Docking Technology of Inductor Replacement Without Stopping Furnace, New Coreless Crucible for Power Frequency Induction Furnace, Wear-Resistant and Refractory Castable (Acid and Alkali Corrosion Resistant) for Gas Producer and Industrial Silicon Furnace, Study on Localization of Lining of Large Aluminum Hydroxide Fluidized Roasting Furnace, Integral Casting Materials and Application Technology of Fluidized Roasting Furnace (Furnace Cover) for Sulfide Ore, Research and Application of Localization of Large Circulating Fluidized Bed (CFB) and Intermediate Reheat Natural Circulation Boiler Lining, Development of LH-1500 Series Refractories and Their Industrial Application in Chemical Kilns, Fundamentals for Integral Casting of Unshaped Refractories in Large Metallurgical Industry Kilns, Application of New Metallurgical Refractory Lining for Electric Furnace (Mineral Heat, Dilution and Electric Heating Front Bed), Combined Lining Technology of Long-life Large Rotary Kiln, and Technical System of Combined Lining Technology of Long-life Large Rotary Kiln. Using these 14 technologies, she has presided over the development of more than 150 kinds of refractory bricks, prefabricated blocks, castable materials, ramming materials, gunning materials and other products in 14 series. These products can be used under harsh conditions such as ultra-high temperature, strong thermal shock, low temperature, strong oxidation, strong reducing atmosphere, strong acid, strong alkali, and heavy corrosion. They not only replace imported refractory products, but also go abroad with the "Belt and Road Initiative" project, and the main products and application effects have achieved leading position at home and abroad. She has won five first prizes, one second prize, two third prizes and one government Science and Technology Progress Award in China Nonferrous Metals Industry Science and Technology Award. Applying these technological achievements, she presided over the development, design and construction of nearly 2,000 furnaces with excellent quality, involving metallurgy, chemical industry, building materials, electric power, national defense special chemical industry, harmless treatment of garbage and waste, etc. These furnaces have a service life of several years or even decades, showing superior comprehensive performance and achieving great economic and social benefits.

At present, she has published more than 30 papers, and the related products and technologies she developed have been listed in manuals, monographs and textbooks such as Design Manual of Nonferrous Metallurgical Furnace, Lead and Zinc Metallurgy, Modern Copper Metallurgyand Unshaped Refractories.

Because of her outstanding contribution to refractories, she was elected as a special researcher and think tank expert of the Academic Committee of the China Academy of Management Science, member of the National Refractory Standardization Technical Committee, vice president of Henan High-tech Industry Chamber of Commerce, member of the Tenth CPPCC in Luoyang City, vice chairman of the Board of Directors of China Mining Engineering and China Nonferrous Metallurgy, and member of the Eighth Committee of Nonferrous Equipment Academic Committee of The Nonferrous Metals Society of China, and was awarded as ambassador of Global Promotion of National Brands, honest entrepreneur, First Top 100 Private Industrialists in Luoyang City, Second Top 100 Private Science and Technology Industrialists in Luoyang City, Henan Province, manager of excellent construction company in Luoyang City, etc. The advanced technological deeds of her and the enterprises she founded have been reported by newspapers, magazines and online media such as People's Representative Newspaper, China Reform Dailyand China High-tech Magazinefor many years.
