Can cold rolled galvanized steel coils be acid washed after oxidation?
If it has been galvanized, it can not be pickled, and if it is pickled, it may corrode the zinc layer
Hot rolling is made of slabs (mainly continuous billets) as raw materials. After heating, strips are made from roughing mills and finishing mills. From the last finishing mill stand out of the hot strip laminar cooling through to the set temperature, the coiling machine rolled strip steel roll cooled, according to the different needs of users with different finishing line (flat, straightening, transverse or longitudinal, inspection, weighing, packing and marking etc.) processing and become steel, flat steel product volume and slitting.
Rolling at room temperature is generally understood as cold rolling, from a metallurgical point of view, below the rolling temperature at which the roll is rolled
