finish strip size based roll sizing for cold reduction mill

USA1

A system is disclosed for controlling the tension in rod or bar products being rolled continuously in first and second roll stands independently driven by drive motors. A first surface velocity gauge is positioned at the delivery side of the first roll stand and a second surface velocity gauge is positioned at the entry side of the second roll stand.

Hot Rolled Steel vs

2020 7 30 Greater strength Cold rolled steel can exhibit strength up to 20 greater than that of hot rolled steel which makes it more suitable for use in high stress applications. Better surface finishes Parts and products made from cold rolled steel generally have a smooth and shiny surface that is free of rust and scale.

Sheet Metal Design Guide

Sheet Metal Fabrication is the process of forming parts from a metal sheet by punching cutting stamping and bending. 3D CAD files are converted into machine code which controls a machine to precisely cut and form the sheets into the final part. Sheet metal parts are known for their durability which makes them great for end use applications

Cold Rolling Process Overview

Cold rolling takes the hot rolled product and processes it further. After hot rolling the steel is cooled to room temperature then passed through cold rollers at a temperature lower than its recrystallisation temperature. This rolling process is called annealing and relieves stress and leads to a higher yield strength and greater hardness.
