A layer of brittle and hard ferric oxide will form on the surface of the steel strip during hot rolling ,and the ferric oxide layer will affect the surface quality o the strip during cold rolling. Pickling process is applied for removing the ferric oxide. We are professional in this technology and we can provide the following kinds of pickling lines, Push-pull pickling line(semi-continuous pickling line) and continuous pickling line.
it is a semi-continuous production line. It is characteristic with lower consumption, easy operation and fewer malfunctions. moreover, it can pickling many kinds of incoming materials. the line can produce 100,000-600,000 tons of trip annually.
It is a production line 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 electric consumption. The annual capacity of the line is 600,000-1,000,000 tons.
