Aluminium rolling models: work roll camber. As many of you may know, we have developed a suite of process models for the aluminium rolling industry. These aluminium rolling models cover everything from ingot pre-heating to tension levelling.

Either the work roll or the back-up roll is driven, depending on customer requirements. The diameter of the 4-high work rolls amounts to approximately 1:4 in relation to the barrel length. This type of rolling mill is mainly used in offline applications for cold rolling of soft and medium strip and for a wide range of strip widths, as well as for break-down rolling in offline applications.

The work roll for 4 Hi and 20 Hi is taken D2 material. The chemical and mechanical properties of D2 materials are as follows: ... The deformation of work roll of rolling mill has been divided in three sections named as Entry Elastic Deformation zone, ...

The 4 hi rolling mill also has an increase in the roll train, so the roll diameter of the work can be much smaller, and the corresponding rolling force is much smaller. It is more suitable for rolling thinner materials, then the whole rolling The thickness and range of the system will be broader.

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.

15-03-2004· I am in the process of replacing an obsolete controller for a roll grinder with a Siemens S7-300 platform. One of the tasks that must be performed is to calculate the profile of the camber of the roll. This is normally done but specifying the depth of the camber at the center point and an...

4.9. ROLL REPAIR ... 4.9.2.1. SPALLS IN WORK ROLLS ... As regards “abnormal” rolling conditions - 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

The work roll for 4 Hi and 20 Hi is taken D2 material. The chemical and mechanical properties of D2 materials are as follows: ... The deformation of work roll of rolling mill has been divided in three sections named as Entry Elastic Deformation zone, ...

They can also be equipped with dual motor drives so that one work roll can be ground a little different in diameter than the opposing work roll. This is becoming common whether a 2-high, 4-high, 6-high, or cluster mill. Before dual motor drives, rolls had to be ground the same diameter. If one roll needs to be ground, the opposing roll must be ...

metal rolling at finishing mill (4-Hi mill Reversible) , work roll pair come out due to the axial crossing of work rolls and due to which uneven thickness of metal, strip breakage, bending of locking plate, metal shifting and equipment breakdown occurs. After the Study it had been observed that wear of the work roll liner is one of the

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:

Manufacturer and Exporter of FORGED STEEL ROLLS named Work Roll, Back-up Roll, Drive Roll, Intermediate Roll, Senzimer Roll, Leveler Roll, Tube Mill Roll etc Rolls are being used in Cold rolling of Sheets and Coils of Stainless sheets, Mild Steel, Aluminium, Copper and others.

17-10-2020· 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.

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.

With hot rolling, 2-high rolling mills have an advantage over 4-high rolling mills because the rolls are self-cleaning, and the work rolls do not need to be replaced as often as they do in a 4-high mill. In any event, the rolls can be pushed out from the side of the mill and quickly changed with new rolls.

the work material; (2) reducing the draft in each pass; (3) using a smaller roll radius R to reduce contact area and then reduce the force; and (4) using a lower rolling speed N to reduce power. 5.4 Shape rolling: In shape rolling, the work is deformed into a contoured cross section. Products made

The successful twin-stand Compact Cold Mill (CCM ®) was originally invented by SMS group.Today we have by far the most CCM ® references worldwide. Featuring a capacity of up to 900,000 tpy, the CCM ® closes the gap between the single-stand RCM and the multistand tandem cold mill. We engineer these mills to achieve the best investment and lowest operating costs for their capacity range.
