Mill, motor and the whole process of roll pass design. Roll pass design is a set of methods for determining the dimensions, shape, number, and type of arrangement of rolling mill passes. Development of a rational roll pass design for a rolling mill using performance criteria. rolling mill pass design pdf
Individual drives for the mill rolls ensure regulation of the rolling speed and simplify the set-up of the mill and the roll-pass 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).

blooming mill[′blü·miŋ ‚mil] (metallurgy) A rolling mill for making blooms from ingots. Also known as cogging mill. Blooming Mill a high-capacity rolling mill for the reduction, into blooms, of steel ingots of large cross section, with masses up to 12 tons and larger. In some cases a blooming mill is used for the rolling of slabs and also shaped ...
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.
Improved roll pass design for long products with WICON Rolling Library WICON Rolling Library is a professional tool for making all the necessary calculations and simulation of the process parameters in a rolling mill. This includes roll pass design, evaluating changes to process conditions,
Casting, rolling and processing lines: Bloom casters, Beam blank casters, Billet casters, Billet and Bloom Grinders, Reheating Furnace for Long

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.
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.
Improved roll pass design for long products with WICON1.30 Мб. Default values have been evaluated from a large number of passes in continuous mills when rolling plain carbon steel between 0.5 - 0.85 %C. MainBar length, the cold or hot length of the bar after the pass.
The program covers all different mill layouts from single stand blooming mills over old looping trains to modern continuous mills, Kocks blocks and 2-High finishing blocks. ... Main module PASS DESIGN ... groove composition in rolls and roll drawings. Module CALCTEMP The program for detailed calculations of the temperature destribution over the ...
Roll wear is amongst the key criteria for devising a rational roll pass design. Rolls in a hot mill have to withstand radial loads up to 12 MN and high temperatures in the range of 900 to 1300 oC. In addition to the obvious need for resistance to breakage, there is the continuing component of roll wear that is critical to the economics of ...
Roll Pass Design for Round Bars G. Perotti (I), N. Kapaj; Dipartimento di Tecnologia e Sistemi di Produzione, Politecnico di Torino/ltaly Received on January 8,1990 In the paper a general computer approach strategy concerning the roll pass design for round bars is presented.
A large rolling mill for rolling large ingots of metal or alloy into billets and slabs, usually a two-roll reversing mill. Can be divided into billet roughing mill and slab mill. In addition to being used as ingots, the products of large steelmaking workshops generally need to be made into billets by the initial rolling mill.
Oct 20, 2017· This video discuss draft, bite angle, length of contact,condition for maximum draft, slip and power requirements for rolling operations If like this video please donate PAYTM 9422112581 UPI ...
Jan 08, 2014· The roll designer will pick the number and size of stands, the reductions at each stand, size motors and drive systems, and design the grooves and roll barrel layouts to provide the most cost effective method of producing the given products. Design a new product to roll on an existing mill.
In shape rolling manufacture, a work piece will often experience different amounts of reduction in different areas of its cross section. 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.
mediate rolling mills, the pass line was bent again by 90 degrees to ... three-roll rolling mills of the latest design. The bar mill produces straight bars of 18–120 mm in diameter and bars in coil of 18–52 mm in diameter. After shipment from the mill, these straight bars and/or bars in coil are processed to end ...
Roll Pass Designs projects typically follow the following timeline: Development of detailed groove drawings, roll barrel layouts, roll stress calculations, rolling power, torque and separating force predictions, and roller set-up sheets. Design review and training sessions with mill personnel
Rolling processes 5-1 introduction: ... ingot is moved to the rolling mill, where it is rolled into one of three intermediate shapes called blooms, billets, or slabs, as shown in figure (5-2). ... rolls is called roll-pass design. Its goal is to achieve uniform deformation throughout the cross section in each reduction.
Oct 22, 2013· 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.
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
