Engineering methodology for calculation the roll pass dimensions in continuous rolling of bars and sections

Abstract

An engineering technique for calculating the dimensions of grooves for rolling profiles and wire rod on modern continuous mills, taking into account the equilibrium of the metal in the rolls and the longitudinal stability of the process, has been developed. It provides coordination of geometric, kinematic and power parameters in the deformation zone at stands of the rolling mill and the wire block. The results of the test calculations correspond to the data of rolling a round profile and rod with a diameter of 8 mm on a mill of 400/200 the PJSC "KAMET-STEEL". In this case, the expansion of the metal is determined analytically without the use of experimental data on the deformation coefficients. The shape of the ovals obtained by the method is more convex. The systemic impact of the results at calculating the roll pass design on the possibility of energy saving and increasing the stability of the process has been established.
