Staggered Work Mill Rolls

2021-1-28 The mill rolls are mainly used for the rolling mill, which cause continuous plastic deformation of the metal.The mill roller is mainly composed of a roll body, a roll neck and a shaft head. The roll body is the middle part of the roll, which actually participates in the rolling of the metal with a smooth cylindrical or grooved surface.

Mill rolls. Rolls for rolling mills - stellite-parts

Work rolls for multiple roll mills are usually made of Steels 9Х and 9Х2, tool, medium alloy and high-speed steels. Work surface hardness as heat treated achieves HRC 61-66. Recent technologies use work rolls made of sintered carbide alloys (tungsten carbide as a base) more and more often. Hard alloy roll manufacturing is based as a rule on hot pressing or sintering plasticized work pieces. Quantity of

Rolling Mill and its Technological Equipments –

Rolling is a continuous process, during which the input material is deformed between the rotating work rolls. Rolling mill is the place where rolling takes place. The roll gap (a gap between the work rolls) is smaller than the material entry height. As per the direction of passing the rolling stock between the work rolls, the position of rolls axes in relation to the rolling stock, and the course of rolling, a rolling mill can

Coil straightening machine - Taixi Mill Roll

Straighteners typically operate five to 11 work rolls whose diameter and center distances vary depending on workpiece-material thickness and width. Generally, rollers are fairly large in diameter, widely spaced and not backed up. Straighteners will remove coil set from the material, allowing it to pass unrestricted through the die and satisfying most applications.

Staggered Joint Coupling: If a roll-neck could be gripped tight then a coupling joint could be placed further outboard without excessive looseness and runout. The joints could then be staggered in which a larger joint was adjacent to a thinner connecting section, and would enable the use of larger, hence stronger joints. See picture below, the u-joints shown would not fit next to each other and without a firm grip on

Rolling of steel and major equipment in a Cross

Rolls – Rolls are normally the main and very costly consumables in a rolling mill. They are most vital part of a rolling mill. The deformation of metal work piece is directly accomplished by the rolls. The rolling stresses are first of all applied on rolls and after that transmitted to other sections of the mill. Therefore, the rolls had to be harder and more resistive to deformation than the metal under processing.

Cluster Mills Metal Processing Machinery

As an example, a Cauffiel 18-high rolling mill is used for running high carbon alloys at an accuracy of ± .00098” ( ± 0.00025mm) at speeds up to 1,000 FPM. A 10-high mill can have a much larger work roll, as it has the advantage of a cooling affect, which means you can run at speeds up to 2,500 FPM with reductions of 50% per pass on low carbon steels. Cluster mills are also less expensive than 18-high
