The rolling mill is equipped with a walking beam furnace with a capacity of 125 tons per hour. Blooms are de-scaled after exiting the furnace, and then proceed through a five stand roughing mill, a six stand intermediate mill, and an eight stand finishing mill. Dimensional control is maintained by optical laser gauges and manual micrometer checks.

GRAPHITE STEEL ROLLS: Characteristics: This type of roll is special type of steel roll where some properties of cast iron must be included in the steel material.The service performance of this roll is superior to normal steel roll; it gives better wear resistance and resistance to fire cracking due to the presence of graphite without reduction of strength and toughness.
Features of multi - high rolling mill
Because the work roll diameter of a 4-h mill is larger, the elastic deformation of the roll itself during rolling is larger than the thickness of the strip to be rolled. The elastic deformation of the roll is proportional to the diameter of the roll at the same unit pressure.

Graphene/elastomer nanocomposites - ScienceDirect
There are three main characteristic bands of graphene and graphite; the D band at ∼1330 cm −1, the G band at ∼1580 cm −1 and the G′ (or 2D) at ∼2650 cm −1. One of the most important functions of Raman spectroscopy on the study of graphene is the accurate information it can provide regarding the number of layers of graphene [84].
