Continuous Pickling Line

Continuous Pickling Line

Continuous Pickling is a production that the steel strip is pulled continuously through the acid tank and rinsing tank. The line is characteristic with high efficiency and output, and low electricity consumption. The annual output of the line is 600000~1800000 tons.
