SUPERIOR MILL PERFORMANCE

Over the years rolling speeds have been continually increasing in order to raise productivity At the same time high reduction rolling of high strength steels requires larger rolling forces This combination amplifies mill vibration which adversely affects the life of mechanical parts operational stability and thus mill productivity.

Reduction of Burr in Rolling Process Through Shear

13 01 2020  Billet rolling is the process of producing long bar shaped billets with a square section This is done by reducing the cross section through multi step reversing rolling and continuous rolling of blooms with a large rectangular section by cooling and solidifying a molten metal in a continuous casting process .Billet rolling mills include a breakdown mill BDM for reversing rolling

What is a Shear Force

15 02 2019  Shearing forces are unaligned forces pushing one part of a body in one direction and another part of the body in the opposite direction When the forces are aligned into each other they are called compression forces For example a force of 10 newtons N is exerted at the edge of a beam This is an external force.

Sheet Metal Cutting Shearing

Blanking is a cutting process in which a piece of sheet metal is removed from a larger piece of stock by applying a great enough shearing force this process the piece removed called the blank is not scrap but rather the desired part.Blanking can be used to cutout parts in almost any 2D shape but is most commonly used to cut workpieces with simple geometries that will be

Shear Forces and Bending Moments in Beams

Summing forces vertically we find V 1 = P Thus an abrupt change occurs in the shear force at a point where a concentrated load acts As one moves from left to right through a point of load application the shear force decreases by an amount equal to the magnitude of the downward load Summing moments we find M 1 = P dx/2 Vdx V 1dx
