A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING …

Hot rolling begins with heating the billet or blooms to a high temperature of around 1100 degrees Celsius. The temperature is of particular importance. Hot rolling and hot extruding drawing involves working above the recrystallization point of the steel. The mill passes the heated material through a variable number of stands.

The deforming behavior of a material during the roll bite in the skewed roll type rolling mill is shown in Fig. 4. Deforming behavior can be discussed in three separate stages. In the first stage, on the entry side of rolling, although reduction is not applied to web thick-ness, the roll side face contacts with the inner side of a flange and

API Engineering

NOTE: Hot-rolling and cold-rolling should not be mistaken for different grades of steel. Steels of different grades can be produced as hot-rolled or cold-rolled. HOT-ROLLED STEEL. 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.

Hot and Cold Rolled Steel Explained - MST Steel Corp

Dec 28, 2016· Hot rolling is often the cheapest way to form steel because additional steps that cold rolled steel requires, such as annealing, are avoided. A bluish iron oxide layer, known as mill scale, forms on the surface of hot rolled steel due to the elevated temperature.
