The subsequent rolling operation in the high-speed tandem mill diminishes the interpass RX process while self-annealing might occur during the cooling of coiled hot rolled strip (35,36). The effect of strain mode and hot rolling parameters on the microstructure and texture evolution is summarized in Figure 4 .
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

Apr 01, 2015· In hot rolling mills, premature failure of rolls is a major concern as it adversely affects the mill operation as well as production. Analysis of failed roll materials and actual rolling conditions in service are therefore necessary to understand the roll failure mechanism and thereby improve the wear resistance and extend the service life of rolls.
Mill Rolls. Mill Roll is the main working component and tool of the rolling mill, and the use is to make the metal continuously plastic deformation. The mill roll is mainly composed of a roll body, a roll neck, and a shaft head, three parts. The mill roll can be arranged in two rolls, three rolls, four rolls, or multi-rolls in the housing.
Sep 30, 2020· The hot metal is passed between two rolls to flatten it, lengthen it, reduce the cross-sectional area and obtain a uniform thickness. Hot-rolled steel is the most common product of the hot rolling process, and is widely used in the metal industry either as an end product or as raw material for subsequent operations.
Oct 11, 2018· Rolling mills are classified according to the number and arrangement of the rolls. A two high rolling mill can further be classified as a reversing and a non-reversing mill. All rolling mills have common construction that is independent of the specific type of rolling required: 1. Backup rolls – are intended to provide rigid support required ...

Hot-rolled coils (HRC) are a type of sheet product resembling a wound steel strip and are produced at hot-rolling mills. These products are widely used for construction, the machine industry, car manufacturing, the production of general-purpose, construction, oil and gas and special-purpose pipes, and as a work-piece for the further production of cold-rolled products.
A rolling mill for rolling metal strip moving in a horizontal rolling direction, has work rolls which engage the strip and are supported vertically by backup rolls through which drive is applied. The work rolls are supported in the horizontal rolling direction by support rollers contacting them at locations confined to intermediate regions between the work regions and bearings.
These backup rolls are larger and contact the back side of the smaller rolls. A four-high mill has four rolls, two small and two large. A cluster mill has more than 4 rolls, usually in three tiers. These types of mills are commonly used to hot roll wide plates, most cold rolling applications, and to roll foils. 
Sep 11, 2014· The differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill, and not the product specification or grade. Hot rolled steel involves rolling the steel at high temperatures, where cold rolled steel is processed further in cold reduction mills where the material is cooled followed by ...
