a basic understanding of the mechanics of rolling mill rolls in brazil

In the conventional hot strip mills the minimum strip thickness rolled was 15 2 mm In thinslab continuouscast rolling mills the strip rolled thickness is below 1 mm and the strip caster aims to cast between 2 and 1 mm In the past it used to take weeks to produce coiled strip from iron ore...
