Selection of Traditional Hot Rolling Mill Roll Material and Heat Treatment Process. Hot rolling rolls often work in a hightemperature environment of 700°C to 800°C. They are in contact with hot steel billets and need to withstand strong rolling force. Subject to thermal fatigue with large temperature changes.
Cyclic temperature changes in the working layer of a roll during hot rolling cause thermal stress which leads to damage on the surface layer of the roll due to thermal fatigue. The preconditions of crack initiation are described. The intensity of crack propagation could be influenced by optimizing the chemical composition and physicalmechanical properties of the material on the working layer.
In one of his drawings, Da Vinci designed a rolling mill featuring a pair of rollers. With that said, modernday rolling mills didn't emerge until the 19th century. In 1820, Bedlington Ironworks produced one of the world's first railbased rolling mills. Railbased rolling mills are those that are designed to create long and narrow beams or ...

Rolling Mill Rolls. 1. Definitions. Rolls are a tool to produce plastic deformation of the metal. It is an important consuming part to determine the efficiency and quality of the rolling mill. Roll is an important part of the rolling mill. The pressure generated by a pair or group of rolls is used to roll the steel.
Tandem rolling mills. Tandem rolling mills use more than two sets of rollers on each side of the metal sheet. For example, using 10 different size roller on one side and the same size roller sets on the opposite side. This is essential when you want to apply heavy force and you won't load distribution to be linear.
