Steel members produced in a steel mill have at least some camber and some sweep. The allowed amount of deviation from straight is defined by the tolerances specified in ASTM A6/A6M . The American Standards for Testing Materials (ASTM) is an international organization that creates and publishes a concensus of technical standards for a wide range of materials.

In this work, finite element simulations have been performed to model camber and lateral movement during hot rolling. To verify the results, experiments were made in MEFOS''s pilot plant mill.
Stephen E. Amos, in Hollow Glass Microspheres for Plastics, Elastomers, and Adhesives Compounds, 2015. Internal Mixers. The use of internal mixers such as the common commercially used Banbury Mixer (schematic in 63)has other considerations for HGM addition. On the one hand, a closed mixing setup is preferred for low density additives because it contains the material and prevents it from
Mill coils with edge wave, then slit into narrow mults, show random camber in the outer strandsfirst in one direction and then the other. It is impossible to adjust for camber that varies throughout the mults. If the coil has continuous camber in only one direction, twist and sweep will be problems during the roll
SPALLS IN WORK ROLLS..... 96 which are more or less very normal for rolling mills roll damage often occurs with consequences for the mill and the rolled product. Evidently the reasons of roll failure have to be discussed and determined

This is where camberfree rolling comes in. It''s based on the interaction of roll alignment control integrated in our automation system and strong, positioncontrolled side guides in the roughing mill stand entry and exit sections. Here''s how it works: The slab contact with the strong, positioncontrolled side guides applies tension to the roll gap.
A twin stand mill with a rougher stand before the steckel mill is suitable for an output of 800,000 tonnes a year. Features.

The camber that must be ground into a roll is very specific to a particular work width, material, and force load. A roll must usually be manufactured for only one metal rolling process. In some industrial metal rolling processes, rolls are given temporary camber by applying forces through their bearings.
6. Mill in misalignment. Tube mill misalignment, poor mill condition, and inaccurate setup account for 95 percent of all problems in tube production. Most mills should be aligned at least once a year. 7. Tooling in poor condition. Operators must know how much life is left in the tooling before the next scheduled rework.
Natural Mill Camber Natural mill camber, which is a slight camber present in a beam when it is received from the mill, will exist in most beams If the natural mill camber is at least 75% of the specified camber, no further cambering by the fabricator is required 34 If camber is not specified, the beams will be fabricated and erected
#0183;#32;Another roll deflection model based on the beam theory for the evaluation of the roll deflection in plate rolling was used by Ohe et al. (1994), where they assumed the pressure distribution between the rolled plate and the work roll as well as between the backup roll and the work roll to be a polynomial of fourth degree.
Work Roll Shift Mill. Primetals Technologies have been a pioneer in the field ever since we developed the world''s first Work Roll Shift Mill and have enhanced this technology based on our extensive experience in steel industry. Primetals Technologies utilizes the Work Roll Shifting at hot strip rolling field for different two purposes:
