    21 Hot Strip Mill Evolution Hot strip mills have evolved in various steps from original tinplate and sheet rolling mills The development of semicontinuous and continuous multistand mills followed, producing smalldiameter and eventually largediameter steel coil productsThe Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semifinished 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 processThe Hot Rolling Process California SteelHot Strip Mill Process Flow Chart 41 Fresh Cold Rolling Mill Process Flow Chart Hot Strip Mill Process Flow Chart has a variety pictures that amalgamated to find out the most recent pictures of Hot Strip Mill Process Flow Chart here, and as well as you can get the pictures through our best hot strip mill process flow chart collectionHot Strip Mill Process Flow Chart pictures in here areHot Strip Mill Process Flow Chart | alberta davidson

  • Highest performing Hot Strip Mills | Primetals Technologies

    The production of hot strip is a key element of steel production Since close to half of all steel produced is hotrolled to strip, mills require maximum throughput and availability combined with geometrical precision and the ability to create optimum materialA process for continuously rolling hot metallic rod into a high quality narrow strip of accurately controlled dimensions using only one pass per mill stand to nevertheless produce a large total reduction, comprising the steps of providing a pair of rolls that engage the rod at a working portion of said rolls characterised by having a diameter that is comparatively small yet large enough to produce said large bite without anyTwo high hot rolling mill process and narrow strip productThis process is now known as the continuous hot rolling process At a pack mill, plates had to be run over the roll and doubled, making the process much slower and more labor intensive The process used at a strip mill was preferred over the processes of the pack mill because the milling process was continuousWhat is a Strip Mill? wiseGEEK
