Founder Introduction ——

Professor Wang Kuihan graduated from Metallurgy Department of Northeastern University. For many years, he has devoted himself to the research of composite materials, new temperature sensors and practical temperature measurement technology, effectively developing critical anti-oxidation technology for tungsten-rhenium thermocouples. He has also developed a variety of high-temperature resistant, corrosion-resistant and wear-resistant materials, and invented molybdenum-based cermet protection tubes, successfully used for continuous temperature measurement of high-temperature molten salt, copper and copper alloy melts. Professor Wang has won the first, second, third, and fourth prizes of the former Ministry of Machinery, Ministry of Metallurgy, Nonferrous Metals Corporation, Liaoning Province, and Shenyang City Science and Technology Progress Award item. He has published more than 100 papers in major journals and magazines in China and abroad; including "Temperature Measurement Technology", "Thermal Testing Technology", "Industrial Process Testing Technology"; participated in the editing of "Metallurgical Physical Chemistry Research Methods", among others; translation Author of Iron and Steel Metallurgy, Physical Chemistry of Metallurgy, New Materials for Opening Up the Future, among others.
