碳化钨的生产有两种工业方法;碳化法和铝热还原矿石或精矿法。多数的 WC 是用碳化方法生产的。在这种工艺中主要有这样几个工序;即精矿的加压浸出,净化,溶剂萃取,仲钨酸铵结晶,二段还原制取金属钨,碳和金属钨混合并在1200℃到1500℃下碳化得碳化钨。铝热还原法包括:矿石或精矿和碳化钙,铝混合成炉料,再将炉料装进衬碳的炉内,引燃炉料,即产生放热反应,将反应得到熔融物冷却、破碎,用水浸方法沉淀出粗的 WC 结晶体。这种粗的 WC 结晶体还
There are two industrial methods for the production of tungsten carbide; the carbonization process and the aluminothermic reduction ore or concentrate process. Most WC is produced by the carbonization method. There are mainly several processes in this process: pressure leaching of concentrate, purification, solvent extraction, crystallization of ammonium paratungstate, second-stage reduction of tungsten, mixing of carbon with tungsten, and carbonization at 1200 ° C to 1500 ° C Got tungsten carbide. Aluminum thermal reduction method includes: ore or concentrate and calcium carbide, aluminum mixed into the charge, and then charged into the lined carbon furnace, igniting the charge, which produces an exothermic reaction, the reaction was melt cooling, crushing, water Baptist method precipitated coarse WC crystals. This rough WC crystal also
