Packaging tin production technology of pickling line is introduced. Hot-rolled coil is cold rolled billet. Because of hot rolled plate roll finishing temperature about 800 ℃ or more generated on the surface tin oxide. Cold rolled steel strip is one of the goals in order to get until the good surface properties. Before the cold rolling is to remove oxide. That is the first purpose of pickling operation: in addition to the surface of iron oxide has physics, Mechanical) Method and chemical method. For the processing of cold rolled billet, is commonly used to increase the surface properties of the chemical method, which adopts the pickling method. The acid with hydrochloric acid, sulfuric acid as most, recently, most use hydrochloric acid production line. Processing time is short, its quality also good. Is given priority to with chemical method, physical method as the auxiliary pole, with the two methods.
