随着等离子喷焊工艺在阀门行业的推广应用,生产与使用合金粉末的单位不断增多,其产量与品种也不断扩大。为统一各生产粉末单位用于喷焊阀门密封面的粉末牌号、逐渐稳定粉末质量、便于用户选用,特制定本暂行规定,供各有关单位参考。编制说明及使用范围1、本规定适用于氮气雾化水冷及水雾化工艺制得的粉末。 With the plasma spray welding technology in the valve industry to promote the use of production and use of alloy powder units continue to increase its production and variety are also expanding. In order to unify the production of powder units for the powder coating valve sealing surface powder grades, and gradually stabilize the powder quality, user-selected, specially formulated this Interim Provisions for the relevant units for reference. Preparation instructions and scope of use 1, the provisions apply to nitrogen atomized water and water atomized powder obtained.
