finishing mills, which will roll the steel in tandem with one another. The workhorse roughing mill has 135" wide rolls for rolling 'broadside' (as the first roughing mill is commonly called) to make a slab wider. A 5,000 hp motor drives 42"-diameter work-rolls through 28:1 gears to reduce the slab's thickness by as much as 2-½".

on cold mill work rolls: •Avoid increases in maximum resultant shear stress above the compressive fatigue strength of the roll by the passing of grit or welds etc. through the roll bite. •Ultrasonic inspection techniques using a dual probe ("pitch/catch") and surface wave
Roll Forming. Roll forming involves bending a long strip of metal (usually coiled steel) that is passed through sets of rolls, with each performing an incremental part of the bend. The finished product is bent until the desired cross-section profile is reached. As you can see, cold rolled steel can be used in a lot of ways and in many industries.
