摘要
对比了 GW30钢结硬质合金与普通的 Cr12熔炼钢在制造螺纹搓丝板上的制造工艺、产品性能和失效特征等方面的差异 ,介绍了 GW30钢结硬质合金制造螺纹搓丝板的工艺方法 ,试验表明 GW30钢结合金制造的搓丝板的使用寿命是 Cr12熔炼钢的 7～ 10倍 ,具有显著的技术经济效益。
The differences of manufacture process, product performance and failure feature between GW30 steel-bonded carbide and general Cr12 smelting steel in respect of manufacturing twistingboard for thread are contrasted. Process method of twistingboard of thread made by GW30 steel-bonded carbide is introduced. The experiment indicates that the service life of twistingboard with GW30 steel-bonded alloy is 7～10 times as long as that of Cr12 smetting steel. It has marked technical economical benefits.
