Continuous Pickling is a production line that the steel strip is pulled continuously through the acid tank and rising tank during the roll change and uncoiling process...The line is characteristic with high efficiency and output, and low electric consumption, The annual yield of the line is 600, 000-1, 000, 000 tons.
