To avoid pass design based on experiences, the authors developed a computer aided pass design system for medium and small section mills relied on the practice of Anyang Iron and Steel Co., Ltd. The mathematics models, system optimization, plot function and application effects of the system are emphatically introduced. The work efficiency of the system increased by ten times than conventional
All depends on the channel size, 7 or 9 passes required to reduce from a rectangular or square starting section. The bar is almost completely enclosed by the top roll in a quot;closed passquot; sequence
Section Rolling Mill. Rolling mills are facilities that carry out a series of processes including rolling the billets, blooms, slab and beam blanks extracted from the reheating furnace into the prescribed size and correcting any bending, cutting them into given lengths,

6. Mill in misalignment. Tube mill misalignment, poor mill condition, and inaccurate setup account for 95 percent of all problems in tube production. Most mills should be aligned at least once a year. 7. Tooling in poor condition. Operators must know how much life is left in the tooling before the next scheduled rework.

mill is required. Pass Design The leader sections for the multiple slit rolling process, 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

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. If the temperature of the metal is above its
Nov 27, 2015#183; Rolls and roll pass design. Rolls are the tools of the rolling mill and are the costliest consumable in a rolling mill. The way the rolls are used to execute their duty of deforming steel is in many cases largely determined by the roll pass design.
The selection of the rolling mill pass system is an important part of the rolling mill pass design.. Whether it is appropriate to select have a decisive impact to the productivity and output of rolling mills, quality, consumption index, and production process operation, so the selection of rolling mill pass design system must be strictly carried out in accordance with specific conditions.
