Rolling: NOMENCLATURE OF ROLLED PRODUCTS

(a) Bending of straight cylindrical rolls caused by roll forces. (b) Bending of rolls ground with camber, producing a strip with uniform thickness through the strip width. ROLLS AND ROLL PASS DESIGN. Two types of rolls—Plain and Grooved are shown in Fig. Rolls used for rolling consists of three parts viz., body, neck and wabbler

Roll Pass Design Proposal - Yola

Aug 25, 2010 Roll pass design is defined by geometry of rolls and rolled solids, by process thermodynamics and by attributes of materials. This research will focus on the calibre geometry of subsequent passes. The key information is contained within the geometry of a rolling pass, which itself may be translated into mathematical functions defining the

Rolling Mills: 6 Different Types of Rolling Mills [Images

Sep 30, 2020 If rolling requires more than one ‘pass’ in the same set of rolls, the material will have to be brought back to the same side after the first pass. 2. Three High Rolling Mills. It consists of three rolls positioned directly over one another as shown in the figure below. The direction of rotation of the first and second rolls are opposite as

Deformation Processing - Rolling

Using slab analysis we can derive roll pressure distributions for the entry and exit zones as: h 0 and h b are the same thing 2tan1 ff RR H hh − φ = ()0 0 2 3 H H f h pYe h = − 2 3 H f f h p Ye h = Entry Zone H0 =H @φ=α Exit Zone

Metal Rolling

The roll zone is the area over which the rolls act on the material, it is here that plastic deformation of the work occurs. An important factor in metal rolling is that due to the conservation of the volume of the material with the reduction in thickness, the metal exiting the roll zone will be moving faster than the metal entering the roll zone

The Hot Rolling Process - California Steel

finishing mills, which will roll the steel in tandem with one another. The workhorse roughing mill has 135” wide rolls for rolling ‘broadside’ (as the first roughing mill is commonly called) to make a slab wider. A 5,000 hp motor drives 42”-diameter work-rolls through 28:1 gears to

Roll pass design optimisation | SpringerLink

Nov 30, 2016 Hot rolling is among the most widely used manufacturing techniques. However, rolling mills are major resource consumers; thus, urgent rationalisation is required in the relevant industrial systems. Roll pass design (RPD) is a principal factor that determines process efficiency, product quality and resource consumption. Therefore, it is important to optimise RPD including the selection of roll

Roll pass design in continuous bar mills - SlideShare

May 18, 2015 Thumb rules in rolls pass design Fittings from oval to round must be 0.3 to 0.7. For ovals width to height ratio must be less than 3.0. 13. Spread When the steel is compressed in the rolls it will obviously move in the direction of least resistance, so usually there is not only longitudinal flow but also some lateral flow

Roll Pass Designing in Continuous Bar Mills

Jul 29, 2010 Roll pass design in continuous bar mills rahul kishore. Analysis of rolling ... 6 High Reversible Cold Rolling Mill Steel Cosmos. Tmt steel Kedar Bhide. ... Square grooves generally have facing angles alpha = 90 only for larger squares. Generally, facing angle alpha is taken as 90 for s 45 mm, 91 down to 25 mm and 92 for s = 25 mm

Effect of pass schedule and groove design on the

The roll grooves in a roller and the roll pass sequence in a hot rolling mill are usually designed based on the type of grades and dimensions of the products and the mill capacity. These have been established over the years based on ana-lytical methods. With modern capability of computer based simulation of the hot deformation process, it is possible to evolve roll groove and pass design in a more predictable

Roll Pass Design – IspatGuru

Jun 18, 2014 Roll pass design is based on the characteristics of initial input (weight of billet/bloom, steel grade, and steel temperature before and during the course of rolling), characteristics of finished rolled product (dimension of section, tolerances and specification concerning to mechanical properties, and surface finish of rolled product), and characteristics of the rolling mill (number of stand, roll
