Hot rolled steel belt way of pickling

Hot rolled off the steel belt way of pickling hot-rolled steel belt plate roll, is under the high temperature rolling and coiling, dozen clad steel belt surface under the condition of the generation of iron oxide can be fast on covering the surface of steel belt, and cover the defect on the surface of the steel belt. From the perspective of steel rolling, if take these dozen of oxidized iron clad steel directly to the cold rolling mill rolling will bring many problems: (1) under the big pressure under the condition of cold rolling, will people clad steel with tin oxide pressure matrix, affect the surface quality of manufacture and processing performance, even cause waste. (2) iron oxide broken junior people roll cooling and lubrication of the emulsion system, damaged the circulation equipment, shorten the service life of the emulsion. (3) damaged the surface finish, the price is expensive cold roll. Therefore, baotou steel belt before the cold rolling, must remove the surface oxide, get rid of defective steel belt. In terms of production of galvanized steel, the use of hot rolled to galvanized steel belt, also want to like using cold-rolled steel plate, to play in front of the galvanized steel belt have clean and active surface. In order to obtain such a surface, for hot rolled steel pickling processing. At present commonly used play baotou steel pickling equipment mainly have three kinds of forms, namely half continuous pickling line, continuous horizontal continuous pickling line and tower pickling line. There are some other way of pickling.
