using an FEM model during the initial passes in a blooming mill, as a function of three different pass schedules, roll groove depth, collar taper angle and corner radius. The simulations predicted the effective strain penetration, load, torque, fish tail billet end shapes, and metal flow behaviour at a chosen temperature, mill rpm and draft.
A New Method for Roll Pass Design Optimisation

Newton''s substitution method has been used to solve the equation. With known reduction between consecutive passes, geometrical dimension of square and diamond passes are computed. A model has been used to calculate pass design of a finishing train of a continuous billet mill producing 60 mm square billet from 120 mm square bloom.
Mar 27, 2003· The 10pass example should be fine if you''re running nonnotched, postcut mild steel. If the section is notched, precut, or highstrength material, you''ll need more passes to achieve desired results. Additional passes allow the material to flow through the mill with less strain. Design the Layout and Roll Tooling
Individual drives for the mill rolls ensure regulation of the rolling speed and simplify the setup of the mill and the rollpass design. Continuous billet mills of very high capacity are in operation in the USSR; their output can be as high as 5 million tons of billets per year (1970).
Another solution for reducing the number of passes in the rolling mills is the employment of automated systems for Roll Pass Design as that proposed by Lambiase and Langella. ... Blooming, cogging and slabbing mills, being the ... A tandem mill is a special type of modern rolling mill where rolling is done in one pass. In a traditional rolling ...

Roll Pass Design; Full pass design revamp. A mill in the US was rollilng suboptimally due to multiple product mix changes over the years. Russula codeveloped a new pass progression with technical experts from the mill. More information
Jun 18, 2014· Long products, roll grooves, Roll pass, Roll pass design, rolling mill, rolls, sections, Roll Pass Design Long products are normally rolled in several passes, whose numbers are determined by the ratio of the initial input steel material (square or round billet or bloom.
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
Steel Steel Billets, bars, and rods: Billets are the feedstock for long products of small cross section. In cases when they are not directly cast by a continuous caster, they are rolled from blooms by billet mills. One method of rolling billets, which are usually 75 to 125 millimetres square, is to use a threehigh mill with box passes, as shown in A in the figure. After a rectangular ...
Nov 27, 2015· Understanding Rolling Process in Long Product Rolling Mill ... Rolls and roll pass design. ... The goal of mill and the roll guide setup is to get the first bar rolled when changing product, on the cooling bed within the tolerance so that it is a saleable product. The data required to perform this function is usually provided in two forms.
