we have a rolling machine with 3 rollers; the bottom has two rollers with diameters of 168 mm and one top roller with a diameter of 219 mm. i want to calculate the required force to bend a 10 mm t
hot mill roughing/finishing mill/descaler top side and bottom side strip temperature. the roughing stands are used to reduce the thickness of the steel while at the same time extending the overall length. as the name suggests, the roughing stands are used to form the metal to roughly the final thickness. since most of the reduction is made in the roughing mill
various rolling mill configurations are available to deal with the variety of applications and technical problems in the rolling process. the basic rolling mill consists of two opposite rotating rolls and is referred to as a two high rolling mill (figure 2a). in the three high configuration figure 2(b), there are three rolls in a vertical column, and the

cold rolling speeds vary but modern mills operate at exit speeds as high as 3000 m per minute. a modern complex including melting furnaces, dc casting facilities, pre heat furnaces, hot mill, cold mill and annealing furnaces involves a very large capital investment which can only be fully justified on financial grounds if a big market is
all coiled flat rolled steel is initially hot rolled by passing a slab through a multi stand rolling mill to reduce its thickness to less than 5⁄8 inch. hot rolled steel destined for the sheet market can be either shipped as black band or cleaned in an acid bath and sold as pickled band. these products are used in non critical surface applications such as
