国外硬质合金生产技术近１０多年来发展较快，其主要特点是：１．进一步完善和推广新工艺、新设备。例如喷雾干燥、球磨搅拌、热等静压和新型成形技术以及大型真空烧结炉等。同时开发了钨钴复合氧化物直接制取钨碳—钴化学混合料、化学生产毫微级钨碳—钴混合料、流化床制粒、 Foreign cemented carbide production technology developed rapidly over the past 10 years, its main features are: 1. To further improve and promote new technology, new equipment. Such as spray drying, ball milling, hot isostatic pressing and new forming techniques, as well as large vacuum sintering furnaces. At the same time, the tungsten-cobalt composite oxide was directly prepared to produce the tungsten-carbon-cobalt chemical mixture, the chemical production of the nano-tungsten carbide-cobalt mixture, the fluidized bed granulation,
