1.前言钢丝拉拔前的磷化处理是高、中碳钢丝生产中的重要工序,也是弹簧钢丝生产的关键。目前国内各金属制品厂多采用高温磷化。近年来我厂由于能源紧张,冬季蒸汽供应不足,磷化液只能维持在60～80℃,满足不了高温磷化对温度的要求,降低了磷化膜质量,使拉丝过程和成品质量受到影响,严重时甚至被迫停产。
1. Introduction Phosphating before drawing wire is high, an important process in the production of medium-carbon steel wire, but also the key to spring wire production. At present, the domestic use of high-temperature metal products factory more phosphate. In recent years, due to energy shortage in our plant, lack of winter steam supply, phosphating solution can only be maintained at 60 ~ 80 ℃, can not meet the high temperature phosphating temperature requirements, reducing the quality of the phosphate coating, the drawing process and finished product quality are affected , Even in severe cases forced to stop production.
