Roll Pass Design IspatGuru

18/06/2014· Roll pass design is based on the characteristics of initial input (weight of billet/bloom, steel grade, and steel temperature before and during the course of rolling), characteristics of finished rolled product (dimension of section, tolerances and specification concerning to mechanical properties, and surface finish of rolled product), and characteristics of the rolling mill

Effect of pass schedule and groove design on the metal

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. The model predictions were validated for typical

(PDF) Roll Pass design for hot flat rolling of plain

The starting point in roll pass design is to draw up the pass schedule which indicates the forms of the passes required to obtain the given profile. At the same time, the number of passes is established, as are the draught for each pass, the sequence and number of turns, distribution of the passes among the mill stands etc.2.1. Roll Pass sketches: Questions and answersa. What are the

Fundamentals of Rolling ScienceDirect

This book discusses as well the different types of rolls for various rolling mills, including blooming, plate, sheet, sheet bar, small section, heavy product, skin passing, and cold rolling mills. The final chapter explains the purpose of roll pass design to ensure the maximum output at minimum cost as well as to reduce the roll wear to a minimum. This book is a valuable resource for rolling

These types of mills are commonly used to hot roll wide plates, most cold rolling applications, and to roll foils. Historically mills were classified by the product produced: Blooming, cogging and slabbing mills, being the preparatory mills to rolling finished rails, shapes or plates, respectively. If reversing, they are from 34 to 48 inches in

Computer-aided roll pass design for continuous billet

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. The elongation values have been optimized by varying the apex angle of diamond. A close agreement between computed and actual values shows the validity of the model. A mathematical model has been developed for computing the geometrical

Metal Rolling Manufacturing

One of the goals of roll pass design is to properly design a series of reductions in such a way as to mitigate the relative differences in shape change between areas, in order to avoid material defects. Improper reductions of the product can cause warping or cracking of the material. Metal rolling practice is not always the cause of warping or cracking, sometimes defects in the metal being

Blooming Mill Article about Blooming Mill by The Free

In modern plants, blooming mills work together with continuous billet mills, which turn out billets for the shape mills. Blooming mills are classified by the diameter of the rolls and occur as (1) single-stand, including double-roll reversing two-high mills (large, 1,150–1,300 mm; medium, 900–950 mm; and small, 750–800 mm; see Table 1), and triple-roll nonreversing three-high mills (750

Reliability-Based Optimal Cluster Mill Pass Scheduling

Optimal pass-scheduling on cluster-type cold rolling mills, use to process flat metals, presents added challenges over conventional (vertical-stack) mills due to the complexity of roll arrangements. Cluster-type rolling mills not only pose difficulties in modeling deflections occurring in the multi-roll stack, they also impose the burden of modeling more sophisticated mechanisms used to adjust
