May 18, 2015· Roll pass design in continuous bar mills 1. African Foundries Ltd. Lagos, Nigeria Presented by Rahul 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 poorly maintained mill costs valuable time and scrap during setup and operation. The mill must be dependable so that the operator is not chasing mechanical problems during normal operation and setup. Improper tube size between each driven and side roll pass. Improper forming in design. Overly tight weld roll settings. drive stands
Roll Pass design for hot flat rolling of plain carbon steel
At a rolling mill, blooms and slabs are further rolled down to intermediate parts such as plate, sheet, strip, coil, billets, bars and rods. Many of these products will be the starting material for subsequent manufacturing operations such as forging, sheet metal working, wire drawing, extrusion, and machining.
Metal Pass improve both roll pass schedule and roll pass software. We provide accurate rolling process models, advanced software engineering technology and mill operation expertise. We work on the rolling of wire rod, bar, section, pipe and tube and strip and plate
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.
rolled to a thickness of 20 mm in one pass. The roll radius is 300 mm, and the rolls rotate at 100 rpm. Calculate the roll force and the power required. For annealed copper, it has a true stress of about 80 Mpa in the unstrained condition and at a true strain of 0.223, true stress is 280 Mpa.
Roll forming is a versatile process that allows design innovation. Setting up a roll forming line requires the expertise of a skilled roll form designer and cooperation between the vendor and manufacturer in developing a successful product. But with the right preparation, the transition can be painless.

the roll. In traditional English units, the total power can be expressed as Power (in hp) = 5.13 Where F is in pounds and L is in feet. Example: A 300-mm-wide strip 25-mm thick is fed through a rolling mill with two powered rolls each of radius = 250 mm. The work thickness is to be reduced to 22 mm in one pass at a roll speed of 50 rev/min.

COUPLED PICKLING LINE & TANDEM COLD MILL High-capacity production of high-quality products For a wide range of products, the required strip thickness, flatness and surface quality can be achieved more economically by linking the pickling and cold-rolling processes.
Use a Finish Pass With a Light Cut. Keep a low cut width (or cut depth if you’re talking the floor of a pocket or surfacing with a Face Mill) and do a separate finish pass. The depth of cut has to be larger than the chip load, or you can get rubbing. Usually something like 2-3x chip load will be right for the finish pass.
The mill also includes the processes of attrition and impact, although these actions are limited if the material is easily reduced by cutting and the screen limiting discharge has large perforations. The mill consists of a rotating shaft with four attached parallel knives and a
