我们研制的DT钢结硬质合金(简称DT合金)技术经济效益显著,是当前比较理想的工模具材料之一。近三年来,在北京地区的电器、无线电元器件、冷冻设备、兵器、民用五金和冶金等方面的某些工厂得到了进一步的推广应用,有几个工厂已将钢结模具纳入工艺和工装图册。 在于发应用工作中,我们不仅努力增加应用单位的数量,而且还力图扩大在一个单位中的应用面,使批量大、寿命低的工模具尽量使用DT合金。 DT steel we developed the hard alloy (referred to as DT alloy) significant economic benefits of technology, is currently the ideal one of the mold materials. In the past three years, some factories in the area of ​​electrical appliances, radio components, refrigeration equipment, armaments, civil hardware and metallurgy in Beijing have been further popularized and applied. Several factories have incorporated steel knurls into the process and tooling drawings book. In the application of hair, we not only strive to increase the number of application units, but also trying to expand the application in a unit surface, so that batch, low life mold workers try to use DT alloy.
