Manufacturing Process Routes for Reinforcing Steels

In the hot rolling process, the cast billet is reheated to a temperature of 1100- 1200°C, and then rolled through a rolling mill to reduce its cross-section (Figure 4). A rolling mill consists of a series of stands, each of which consists of two cylindrical rolls into which grooves are cut to accommodate the material being rolled.

Steel Forming Process: Hot Rolled, Cold Rolled, Forging ...

Steel Forming Process 1 – Hot Rolled Steel. Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel's recrystallization temperature. When steel material is above the recrystallization temperature, it can be shaped and formed easily, and the ...

The Pickling Process - California Steel Industries

The Pickling Process CSI's 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.

Hot rolled strip - Australian Steel Products

The product designations are based on those of the Australian Standard AS/NZS 1594:2002. The temperature at which hot-rolling is completed results in an oxidized strip surface. This oxide film is termed hot-mill scale. Pickling removes the hot-mill scale. Pickled strip is generally supplied oiled to preserve this surface finish.
