Reduction Process of Blue Tungsten Oxide and its Microcomputer Process Control
The grain size control of the tungsten powder is essential for high quality tungsten products making. Based on the studies onthe hydrogen reduction process of tungsten oxide, a microcomputer system is introduced to the reduction process parameters con-trol. The microcomputer process control system, which is now running in Zhuzhou Tungsten and Molybdenum Materials Plant,controls the process parameters including the temperature of the reduction furnace and the pressure of hydrogen.
