Hot rolled strip steel pickling way

Packaging steel strip manufacturer to introduce the way of hot rolled strip steel pickling hot-rolled band steel plate, is under the high temperature rolling and coiling strip table and under the condition of the generation of iron oxide can be tightly covered on the surface of strip steel, and cover up the strip surface defects. From the perspective of steel rolling, if take the iron oxide strip directly to cold mill rolling will take m many problems: (1) under the big pressure under the condition of cold rolling, will press oxidation iron into steel substrate, 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 loop device. Shorten the service life of the emulsion. (3) damaged the surface finish, the price is expensive cold roll. Before in cold rolled strip is, therefore, must be removed its surface oxide, get rid of defective strip. In terms of production of galvanized steel, the use of hot rolled strip for galvanizing, also want to like using cold-rolled steel plate, galvanized before to make the surface of the strip have clean and active. In order to obtain such a surface, for hot rolled strip steel pickling processing. Strip steel pickling equipment presently used 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.
