High Speed Steel Rolls. Highcarbon highspeed steel roll (HSS roll) is the hotroll material with the shortest appearance, the fastest development, and the widest application prospect. Highspeed steel, also known as wind steel or front steel, means that it hardens even when cooled in the air when quenched and is sharp.

In the mill, viscous materials (or pastes) pass through the narrow gap between the rolls to be mixed, refined, dispersed, and/or homogenized. The viscous materials tend to consist of wetparticles connected by liquid bridges. Although viscous materials always adhere to a faster roll in the threeroll mill, the mechanism has not yet been clarified.

Rolling schematic view Rolling visualization. In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of is classified according to the temperature of the metal rolled.
