Rolling consists of making a material – billets or blooms in the case of Long Product Hot rolling Mills- pass through two rolls that turn at the same speed but in opposite rotating sense, with the aim of reducing the material’s cross-section due to the pressure exerted by the rolls. In a previous stage, the billet has to be homogeneously heated up to a given temperature, i.e. rolling temperature, in a Reheating Furnace.
Several products can be obtained from these Rolling Mills from bars, rebars, sections, rails, rims, wire, tube, etc.
Two main types of installations can be found in the Long Product Rolling; continuous and discontinuous (also named cross country. The first consists of the rolling of the bar in one sense in a continuous way during roughing, intermediate and finishing mill stages. The latter consists of the alternating rolling in the roughing mill composed normally of a 2-High or 3-High stands. Intermediate and finishing mill stages are carried out continuously.
