Galvanized wire is made of high quality low carbon steel rod processing, is made of high quality low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, hot dip galvanizing, cooling and other processes.
Galvanized iron wire has good toughness and elasticity, the amount of zinc can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance.
In the production process, some parts in order to meet the high hardness and good wear resistance and use high quality steel or through strict heat treatment process, in order to meet the technical requirements. If ordinary carbon steel processing can meet the strength requirements, considering the specific working conditions and the possibility of process implementation and economy, composite iron plating layer can be used for surface strengthening. Iron base composite coating has high hardness and good wear resistance, so it is difficult to process and can only be grinding. It is more convenient if it is used in surface strengthening of parts that do not need machining.
It is better to control the temperature of 30 to 50℃ for galvanized iron wire. Quartz glass heater is generally used because the chloride ion in the bath is highly corrosive. Continuous production does not need heating, but needs cooling. Cooling method: Thin-walled plastic pipe can be closely arranged on the edge of the groove and cooled by flowing tap water, or titanium pipe can be used as temperature control device. In the process of composite electroplating, it is necessary to stir the bath to obtain the composite coating of particles dispersed in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath reciprocating and so on.
