rolling, in technology, the principal method of forming molten metals, glass, or other substances into shapes that are small in crosssection in comparison with their length, such as bars, sheets, rods, rails, girders, and wires. Rolling is the most widely used method of shaping metals and is particularly important in the manufacture of steel ...

Fundamental concept of rolling of steel is given below. The arc of contact between the rolls and the steel is a part of a circle. The coefficient of friction is constant in theory, but in reality it varies along the arc of contact. The steel material is considered to deform plastically during rolling.

Tribology. John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 The Dependence of the Coefficient on the Surface Roughness of the Roll. Dick and Lenard (2005) conducted cold rolling experiments on lowcarbon steel strips, using progressively rougher rolls in a STANAT twohigh variable speed mill. The strips were lubricated by O/W emulsions, delivered at a rate of 3 l/m.

The amount of mill scale generated in a rolling mill depends on the type of the reheating furnace and on the practice of rolling adopted in the mill. It is generally in the range of 1 % to 3 % of the weight of the steel rolled. Mill scale mill scale is a layered and brittle material, composed of iron oxides with wustite as a predominant phase.

1. The higher the yield strength, the more that the material springs back. 2. The larger the forming radius, the more the spring back angle. For example, when you bend ¼" plate to a ¼" radius 90 degrees, A36 will springback is only degrees. Gr50 will springback still is only degrees. But if the radius is larger, say 2", then.

Fig 3 Rolling of thick plate in a plate mill. Prediction of stresses and rollseparating force Once the spread (the boundary of the deformation zone) has been calculated, this information can be used to predict the stresses and the rollseparating force. The computerized procedure used here is in principle the same as the method described for predicting the stresses in strip rolling.
