硬质合金作为工具材料的生产和应用,已有六十多年历史了。我国硬质合金的生产发展较晚,1958年才开始大批量生产和应用。目前,硬质合金生产已建立起比较完整的工业体系,特别是随着整个工业建设的迅速发展,对硬质合金工具材料提出了高、精、新的要求。为了适应新形式,我国硬质合金行业厂家都非常重 Carbide as a tool for the production and application of materials, more than 60 years of history. China’s production of cemented carbide development late, only in 1958 began mass production and application. At present, carbide production has established a relatively complete industrial system, especially with the rapid development of the entire industrial construction, the carbide tool material proposed high, refined, new requirements. In order to adapt to the new form, China’s carbide industry manufacturers are very heavy
