SMS DEMAG Hot Strip Mills 10 The drum-type shear installed between the roughing and finishing mills of a hot strip mill crops the trans-fer bar at its head and tail. In special applications, the drum-type shear also serves to divide transfer bars and finished plates. Based on the experience gained from more than 60 drum-type shears built so far,
Work roll thermal expansion (crown) plays an important role in controlling strip profile and flatness of the strips. This can be done with a perfect and controllable cooling system which also takes care of the work roll against damage induced by fire cracking.
in multi-roll cold rolling mills. In close partnership with the customer, we therefore continually design, test and develop to production-ready status new bearings optimally suited to this application. The quality of FAG and INA back-up rollers is ensured by means of high precision machining and sophisticated measurement methods.

corrosion protection systems require certain design details and proper planning to ensure the highest quality coating. So regardless of the protection method specified, it must be factored into the product's design. For hot-dip galvanizing, a total immersion process in molten zinc, the design engineer will
Oct 18, 2017· ️First of all, Happy diwali to all my subscribers and viewers as well.️ Hello guys, I welcome you again in this new fresh topic. This topic is regarding the rolling process used for ...
rolling mill, dedicated roll cooling systems are required to fulfill the required functions. Examples are suitable roll cooling and lubricationsystems to fully utilize the advantages of HSS rolls in hot strip mills, and selective roll cooling systems as a method to control the flatness of the strip in cold rolling mills.
maintenance, roll covers and replacement rolls are also available. Inspections minimize unexpected downtime Regular roll inspections are the key to avoiding unexpected failures. Valmet's experts compare inspection results with the original roll specifications, then, based on that comparison, provide the mill with maintenance recommendations.
A Basic Understanding of Chill Rolls Published: October 01, 2000, By Michael Puhalla, New Castle Industries, New Castle, PA, USA A chill roll primarily acts as a heat transfer and finishing device in the extrusion of flat sheet and cast film and in coating operations.

Oct 10, 2016· Metallurgical Processes and Defects in Steel Products . ... The deviation from complete flatness is the direct result of the steel relaxation after hot or cold rolling, due to the internal stress pattern caused by the non-uniform transversal compressive action of the rolls and the uneven geometrical properties of the steel being fed for the ...
A simple roll deflection model has been developed to predict the deflection of the finishing stands of a hot strip mill. The roll deflection model indicates the effect of width for deflection as well as the effect of bending. The effect of work roll bending and the roll width has been studied by this model.
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.
The effects of hot rolling on the surface roughness and oxide layers such as reduction, roll speed, and entry temperature, were investigated to identify any significant parameters. Hot rolling experiments were carried out on a HILLE-100 experimental rolling mill. Five .
