In order to solve the serious backup roll spalling of roughing mill during ultra-wide stainless steel rolling process, a 3D elastic deformation finite element model of 4-high roll stacks was ...

4-Hi Mill, 4-High Mill | Waterbury Farrel

The larger backup roll positioned against the smaller work roll reduces separating forces and permits the rolling of wider and thinner materials with a more uniform gauge. 4-Hi Mills are cost-effective and produce a wide range of sheet products with precise control over finished product quality. These Reversing Mills offer considerable ...

4-High Rolling Mills | Metal Processing Machinery - American Steel

4-High Rolling Mills. Four-high rolling mills can be put in tandem, two to seven stands, instead of a reversing mill. They can be equipped with load cells to tell the separating force and hydraulic or mechanical screw downs, depending if it is hot or cold rolling. Sometimes mechanical screw downs are preferred when there is a risk of fire.

Roughing End Mills | Machine Tools | Regal Cutting Tools

Roughing End Mills - Cobalt and High Speed Steel. Regal Cutting Tools manufactures a variety of roughers for a wide range of materials and conditions. Heavy cuts can be achieved because our roughing end mills have a much higher effective feed per tooth than a conventional end mill. Normally a 20% reduction in effective horsepower is used.

Aluminum Hot Rolling Reversing Mill Application Overview - Williamson IR

Roughing/Reversing Mill Application Overview At the reversing mill, rolling speed, roll bite and coolant flow may be optimized only with a precise real-time knowledge of metal temperature. The low and highly variable non-greybody emissivity character associated with this complex aluminum process dictates the

What are the Types of the Rolling Mills? - Xi'an Weikeduo Mechanical ...

· Reversing mill . In two high reversing rolling mills, the rolls revolve ist in one direction and then in the various others, to ensure that rolled steel may pass to and fro via the rolls a number of times. This kind is made use of in plumbing and also slabbing mills and for roughing operate in plate, rail, structural, and also other mills.

Hot Strip Mill - an overview | ScienceDirect Topics

Roll Design1. John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 3.5 Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Back-up rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill).

Blooming mills are typically 2-high reversing design with 30" to 50" diameter work rolls. Reversing roughing mills are a similar design and start with a cast or rolled billet and are used to reduce the cross sectional area of the workpiece prior to entering a finishing mill. The work rolls of roughing mills range from 16" to 36" in ...

ROLLING-(A Brief Guide To Rolling And Rolling Mills)

Generally, they are two high reversing mills (24-54-inch diameter rolls) For high production rates, universal mills are used to take care of edging (two vertical rolls to control the edge). High-pressure water jets remove scales. Subsequent to the last finishing stand, strips are sheared to the required size or coiled to obtain continuous sheets.

Billets or strips are produced in these mills. They operate in the forward direction only. The mill-stands are of two kinds here, roughing mills-stands and finishing mill-stands. These stands are also two or four high depending upon the number of rolls the stand has. In a four high stand inner rolls are smaller than the outer ones.
