The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.

This process was designed to greatly reduce the grain size of ferrite in C-Mn steel without much increase in the rolling load in hot strip mills. To maintain the rolling load within a practical range, the rolling temperature in UDCSMR is kept as high as that in conventional hot strip mills (see Fig. 24.3 ).

2010-6-11 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.

In the mini-mill process, high-grade steel scrap is combined with pig iron, hot briquetted iron (HBI), and other metals and melted at a temperature of approximately 3,000 degrees Fahrenheit in an electric-arc furnace (EAF). The exact mixture is determined by each customer’s specifications. After other important steps are completed, the steel ...
