Pickling Line

A layer of brittle and hard ferric oxide will form on the surface of the steel strip during the hot rolling,and the ferric oxide layer will affect the surface quality of 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. Push-pull Pickling LinePush-pull Pickling is a semi-continuous production line.It is characteristic with lower consumption,easier operation and fewer malfunctions,moreover it can pickle many kinds of incoming material. The line can produce 100,000-600,000 tons strip annually.

Process ParameterFollowing is the data for Push-pull Pickling hot rolled strip with the annual yield of 400,000 tons

Continuous Pickling LineContinuous Pickling 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 yield or the line is 600.000-1,000,000 tons.Process FlowCoil Prepare Station→Coil Car→Pay-off Reel→Pinch Straightener→Cutting Shear→Welder→1#Bridle Roll→Entry Accummulator→Front Tension Reel→Descaler→Back Tension Reel→Pickling→Ice Water Clean→Hot Water Clean→Dryer→2#Bridle Roll→Exit Accummulator→Bridle Roll→Control Roll→Cutting Shear→Disc Shear→Feeder→4#Bridle Roll→Oiler→Pinch Roll→Tension Roll→Unloading Car
