The wiping technology of one-step hot-dipping galvanized galfan steel wire with cracked liquid ammonia gasis studied, and better surface quality is obtained by adjusting current density, the padding speed and wiping process.

主要研究了钢丝单镀Galfan合金液氨分解气体抹拭的工艺原理,通过调整电流密度、走线速度,抹拭方式等工艺参数来获得良好的表面质量;试验表明:当电流密度在6。

Microstructure of SUS304 and SUS321 cold rolled stainless steel strips after annealed with N2 and ammonia dissociated atmospherewas investigated by using metallographic microscope,SEM and TEM.

采用金相显微镜、扫描电镜、透射电镜等手段研究SUS304和SUS321冷轧不锈钢带经氮气气氛和氨分解气氛保护退火后的微观组织,并分析钢带截面显微硬度和退火前后含氮量的变化。
