Defects such as surface film and surface inclusions can be found and treated by conventional techniques in order to remove them locally from the surface of the deposition layer. Excess foam is formed when soap and surfactants such as saponified fats are brought into the tank.

Raw material of wire mesh sheet cold drawn low carbon steel wire base material can choose low carbon steel hot rolled disk bar or hot rolled smooth steel bar. The base material number and diameter of cold-drawn low carbon steel wire can be confirmed according to the rules in the table below. During the cold drawing process, the surface shrinkage rate of each drawing should not be greater than the wire mesh before cold drawing. Annealing shall not be carried out during wire drawing. If butt welding is required, the same production unit and base material of the same number should be selected. The appearance quality of wire mesh should not affect wire drawing. When the welding function is poor or brittle fracture occurs, special inspection should be carried out according to relevant standards.

This oxide film has greater elasticity and lubricity, does not affect the accuracy of parts. Therefore, the parts of precision instruments and optical instruments, spring steel, thin steel sheet, fine steel wire and so on are commonly bluing treatment. The commonly used galvanizing treatment of large roll galvanized wire is equivalent to forming a protective layer on the surface of the iron wire. The commonly used methods are hot dip galvanizing, hot spray plating, vacuum plating and so on. Different methods have corresponding characteristics.

Galvanized wire is processed from low carbon steel wire rod, after drawing forming, pickling rust removal, high temperature annealing, cooling and other processes. Galvanized wire is widely used. Electroplating temperature should be controlled at 30 to 50℃. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used.
