The integral roll is relative to the composite roll. The outer layer and the center of the roll body and the roll neck are cast or forged from a single material, the structure and properties of the outer layer of the roll body and the roll neck are controlled and adjusted by casting or forging process and heat treatment process. Forging roll and static casting roll belong to integral roll. Roll according to material mainly divided into which categories? According to the material, the roll can be divided into three categories: cast steel roll, cast iron roll and forging roll. 
         What is casting roll, what kind does casting roll have mainly?  CAST rollers refer to the types of rollers produced by pouring molten steel or molten iron directly into the mode of production. Casting roll can be divided into cast steel roll and cast iron roll according to material, and integral casting roll and composite casting roll according to manufacturing method.
Which rollers are suitable for integral casting production? 
         The rollers used in roughing mills such as blooming mills, continuous billet mills, heavy section and rail beam mills, hot strip mills for scale breaking and edging, edging mills for Section Mills, as well as roughing stands for small section and wire rod mills, most of them are produced by integral casting, which has a thick layer and a deep pass. In addition, the two-roll roughing roll of hot strip mill is also suitable for integral casting production. The method of integral casting roll is relatively simple and the manufacturing cost is low.
