The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
A hot strip mill (HSM, Fig. 1) is the association of n stands in a line, where each stand is constituted by a set of rolls. The lateral movement of the strip, with reference to the mill axis, is the consequence of rolling asymmetries linked to the stand, such as differential stand stretching or work rolls tilting.

Steel - Steel - Forming of steel: Forming processes convert solidified steel into products useful for the fabricating and construction industries. The objectives are to obtain a desired shape, to improve cast steel's physical properties (which are not suitable for most applications), and to produce a surface suitable for a specific use.
Consider the hot rolling of a low-carbon steel strip in a single stand roughing mill. Let the entry thickness of the slab be 20 mm and its width to be 2000 mm. Its resistance to deformation is taken to be 150 MPa. It is reduced by 30% using work rolls of 800 mm diameter, rotating at 50 rpm.
According to cutting loss of the head and the tail of hot rolling wide strip mill for the loss of width, the control conditions, the control mode and control model of short stroke control (SSC) of the rough mill are researched and given by dynamical changing the rough mill roll gap for SSC simulation and basing on infinite element method (FEM) analysis and results.
Nov 28, 2017· A reversing mill is a rolling mill in which the workpiece is passed forward and backward through a pair of rolls. The reversing mill is so named because the steel runs back and forth between the rollers, reducing the thickness incrementally with each pass. A reversing mill can be used to reduce material to gauge.
Hot Strip Mill Reversing Rougher Mill Study: Yer: Ereğli-TURKEY: İş veren: Erdemir: Proje Tanımı: Detection and correction of the causes of the movements of the rough rolling coils of the reversal by the UEC firm.

Hot strip mill. Around a third of the products we send out to our customers, are hot rolled. In the hot strip mill (Ghent), slabs coming from the continuous caster are rolled out to steel plates with a thickness of around 1.25 to 13mm. How does this work? First, the slabs coming from the continuous caster are pre-sorted in the slab yard.
classed as sheet, also called "strip" (thickness less than 3 mm,) or plate (thickness more than 3 mm). In profile rolling, the final product is either a round rod or other cross sections shaped products such as structural sections (beam, channel, joist, rails, etc). The initial breakdown of ingots into blooms and billets is done by hot-rolling.
Secondary scale on hot strip and the impact on wear is another issue. Stresses from Hertzian pressure in 4-high cold mill back up rolls were measured years ago, the results were never published, but of high interest - also, maybe later. K. H. Schröder July 2003 K. H. Schröder: A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING MILL ROLLS
Latest design of compact hot strip mill from . Latest design of compact hot strip mill from SMS Siemag ... its hot strip mill in 2010, ... r Fig 2 The four-high reversing rougher with attached edger.
For example, a semi-continuous hot-strip mill has only one reversing rougher in front of the finishing train. Another rolling system goes even farther and uses one four-high reversing rougher and one four-high reversing finishing mill, with hot-coiling boxes in front and in back of the finishing mill. (Hot coilers operate in a furnace to keep ...
In this paper, the spalling causes of backup rolls in a roughing mill of a hot strip rolling mill were investigated. The roughing mill withstood extreme service conditions with long service cycles for backup and work rolls, a large variety of the same width rolling campaigns, severe and non‐uniform wear contours of backup and work rolls.

Sep 15, 2005 · Five ingoing strip thicknesses were considered, each one representing a particular pass of the reversing rougher at Corus Port Talbot hot mill. Alterations were made to the finite element model's boundary conditions, i.e. roll gap height, to determine how the reduction affects the magnitude of strip .

Apr 12, 2016· East Work's hot strip mill was installed with 6 finishing stands in 1928, after John Tytus had perfected the continuous process at Ashland, and the mill was running into the early 70's. Four pickling lines (including a heavy gauge pickler) were the destination after the hot bands had cooled, and removed any rust and scale prior to cold rolling.
