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
Primetals Technologies has more experience than anyone of the design and supply of modern wide plate mills, allowing us to develop and use engineering tools for the plate mill application specifically. Tools for Successful Design. Bespoke Process Models (incorporating metallurgy as well as rollbite mechanics and heat transfer)
mediate rolling mills, the pass line was bent again by 90 degrees to ... threeroll 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 ...
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.
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.

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 ...

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.
Ingot is commonly used name for the large sized castings produced in a foundry or during iron making. There are no specific standard dimensions for ingots. In steel plants, the molten metal from the blast furnace is poured into large, cylindrical...
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.

Rolling processes 51 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 (52). ... rolls is called rollpass design. Its goal is to achieve uniform deformation throughout the cross section in each reduction.
May 18, 2015· Roll pass design in continuous bar mills 1. African Foundries Ltd. Lagos, Nigeria Presented by Rul Kishore 2. Basics of Rolling A rolling mill consist of several, at least two rolls cylindrical or nearly cylindrical bodies which are termed as "roll" and which rest in bearings at their ends. The normal and average center distance from the center of one roll to the center of o
A large rolling mill for rolling large ingots of metal or alloy into billets and slabs, usually a tworoll 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.

Initial rolling condition and roll pass schedule Ф100mm 37Mn5 tube billet is designed to be rolled out by 200mm×200mm cast bloom through the sixpass continuous rolling mill with horizontal (H) vertical (V) alternative arrangement. The roll diameter of the first pass (H1) and second pass (V2) is 700mm and the last four passes (H3,V4,
In shape rolling manufacture, a work piece will often experience different amounts of reduction in different areas of its cross section.

Improved roll pass design for long products with Мб. Default values have been evaluated from a large number of passes in continuous mills when rolling plain carbon steel between %C. MainBar length, the cold or hot length of the bar after the pass.
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
