mill is required. Pass Design The leader sections for the multiple slit rolling pro-cess, e.g. square, rectangular or round have to be of very close tolerance. This requires: * Correct pass profile in the rolls * Correct roll gap to ensure no overfill * Correct pass alignment between top and bottom rolls * Sound roll neck bearings and positive roll

Rolling system design is the preparation of a series of roll pockets and draughting sequences for roll passes that are necessary to obtain a group of roll profiles. The purpose of RSD is to ensure the correct production of roll profiles within the constraints of the mill with acceptable qualities, minimum cost [1] and maximum output. This

A: A rolling mill is used to roll a metal sheet thinner. A rolling mill is also used for rolling wire, fold forming, imprinting patterns on metal sheets or forging elegant tapers on a wire. Q: How do you clean a rolling mill? A: You need to clean and maintain your rolling mill properly to prevent rusting, just like any other steel tool.

The roll pass designers attempt to keep the factor η as small as possible at any point of the groove surface. The limits of the ratio h/c are determined by the geometry of the final product, by mill layout (as in Fig. 8) and by the solid flow of the hot rolled steel.
