Rolling Mills

A rolling mill, also known as a reduction mill or mill, has a common construction independent of the specific type of rolling being performed: Rolling mills Rolling mill for cold rolling metal sheet like this piece of brass sheet Work rolls Backup rolls – are intended to provide rigid support required by the working rolls to prevent bending under […]

Roll bending

Roll bending Roll bending Roll bending produces a cylindrical shaped product from plate or steel metals . Roll forming Roll forming, roll bending or plate rolling is a continuous bending operation in which a long strip of metal (typically coiled steel) is passed through consecutive sets of rolls, or stands, each performing only an incremental […]

Hot Rolling VS Cold Rolling

Hot rolling A coil of hot-rolled steel Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets. If these products […]

Rolling

In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is known […]

Ductile cast iron rollers with perlite ground

  These rollers are essentially semi-refrigerated rollers, but the graphite in them is spherical rather than shell and sheet-shaped. Naming these rollers is based on the existence of spherical graphite and carbides in the perlite ground. Due to its high hardness and surface, good abrasive resistance and sturdy arms, it is widely used in the […]

Ductile cast iron rollers with martensitic ground

    These rollers have higher hardness and abrasive resistance than perlite refrigeration rollers and are capable of achieving high hardness. These rollers have more alloying material than perlite rollers and as a result, these rollers have a bainite ground with more carbide and martensite in harder grades. Very good abrasive resistance and excellent surface […]

Ductile cast iron rollers with ferritic ground

    The graphite shape in these rollers is spherical, surrounded by a layer of ferrite. The ground structure of these rollers is often perlite in low-alloy grades and often bainite in the alloy grades and thermal operations. In all grades, a considerable amount of ferrite has surrounded each sphere. Carbide does not form. The […]
