Аннотация
Research on expanding the product range and minimizing the energy costs at a linear medium-bar mill with three-high roughing stands is discussed. The possibility of controlling the mechanical properties of the product by decreasing the initial rolling temperature is considered. Despite the improvement in mechanical properties, decrease in the initial rolling temperature in the range 900–950°C is accompanied by increase in current load at the primary drive and decrease in dimensional precision of the product.
