简单介绍了WC Ni系大直径无磁硬质合金模具的研究开发过程。研究表明 :碳含量和碳的分布对无磁合金的影响最大 ;生产大型无磁合金模具的关键工艺因素是脱胶过程中的控碳。 The research and development process of WC Ni series of large diameter non-magnetic carbide molds are briefly introduced. The results show that the distribution of carbon content and carbon have the greatest impact on the non-magnetic alloy. The key process factor in the production of large non-magnetic alloy mold is carbon control during degumming.
