The Differences Between Hot and Cold Rolled Steel steel rolling mill hot rolled pickling

Hot-rolling refers to a mill process in which you roll the steel at a temperature above its recrystallization temperature; a heat that typically exceeds 1000° F. When steel is heated past its recrystallization point, it becomes more malleable and can be properly formed and shaped.The Differences Between Hot and Cold Rolled Steel steel rolling mill hot rolled picklingWhen the steel cools off, it will shrink non-uniformly, which gives slightly less control on the overall size and shape of a finished hot-rolled product. Hot-rolled steel typically has a scaly surface finish.The Pickling Process - California Steel Industries, Inc.The Pickling Process CSIs pickling line started up in late 1994, and typically processes two out of every three coils produced at the Hot Mill. Its primary function is to remove the thin layer of oxidized iron, or scale, that forms on the surface of the steel at the temperatures employed during hot rolling.

In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.

What Is Steel Pickling? | National Material Company steel rolling mill hot rolled pickling

Before most cold rolling processes, previously hot rolled steel goes through a pickling line to remove the scale from the surface and make it easier to work.
