[0002] The steel wire heat treatment pickling and phosphating continuous production line is a process of converting the steel wire into a sorbite structure and pickling and phosphating the steel wire surface to meet the structure and surface state required for advanced drawing and deep processing of the steel wire. Since the total acid point and free acid of the online phosphating solution will decrease with the continuous phosphating of the steel wire, it is necessary to continuously add it. Generally, it is directly added in ton barrels. The opening of the valve is generally controlled by the on-site operator. If the control is not good, the total acid point and free acid indicators will exceed the control range;
