一、前言 金属钨粉是生产硬质合金、照明灯泡和电子管用钨丝等制品的主要原材料,而制品的质量在很大程度上取决于钨粉质量——化学纯度、颗粒大小、粒度分布和粒形等。化学纯度问题主要靠提纯工序解决,而钨粉粒度控制问题则主要靠还原工序解决。众所周知,制取钨粉过程中,控制粒度的因素主要包括原料种类、还原温度、装料量、推舟速 I. Introduction Metallic tungsten powder is the main raw material for the production of tungsten carbide, lighting bulbs and tungsten tubes for electronic tubes. The quality of the products largely depends on the quality of tungsten powder - chemical purity, particle size, particle size distribution and Grain and so on. Chemical purity problems mainly rely on the purification process to solve, and tungsten powder particle size control problems mainly rely on the reduction process to solve. As we all know, the preparation of tungsten powder process, the control of the particle size of the main factors include the type of raw materials, reduction temperature, loading volume, push the boat speed
