Tungsten Smelting Endless Struggle Research:Linsheng Wan

Jiangxi University professor eighth National Congress, led chaired by his "white (black) tungsten ore preparation of ultra-clean and efficient high-performance tungsten powder sets of technology and industrialization" project research results at home and the first to achieve the industrialization of tungsten "Green smelting" changed the Chinese tungsten smelting position in the international arena.

Professor Wan Linsheng for the low yield of tungsten metal industry, high smelting costs, waste of resources and serious environmental pollution, APT can not produce high-performance powder, which seriously hampered the international competitiveness of China's tungsten industry and sustainable development, this major the key question, which lasted 20 years, systematically studied the crystallization kinetics of APT, independent research and development "APT physical control" and "low-alkali efficient decomposition", "blur exchange - super desorption", "mother caustic crystalline transformation - depth deaminase" "dual exhaust backflow vortex crystalline ammonia condensation "five core technology at home and abroad for the first time in black and white tungsten ore efficient and clean preparation of ultra-high performance industrial production of tungsten powder. Independently designed and built the world's first largest annual 15,000 tons APT, tungsten nanoscale tungsten powder and tungsten carbide powder smelter.
