Abstract
This article describes a combined continuous casting and rolling line and its design while indicating the capabilities of such line in terms of the quality of steel sheets. The initial data are given that are necessary to understand the stress-strain state of steel in the cyclic deformation zone when producing 3-8 mm thick and 2,250 mm wide sheets from the 09G2S steel. The results of the calculation are presented of the axial stresses occurring at the contact line between the de-formation zone and the movable platen. The calculation was performed using the finite element method with the help of the ANSYS software. The authors analyse the stress pattern in the cyclic deformation zone in terms of obtaining high-quality steel sheets. The article describes a method for determining stresses in the movable platens of a four-plate mould based on the reduction force, and a model of the movable platen with cooling channels. The movable platen load pattern is shown. The results of the calculation are presented of the stress state of a movable platen cal-culated against the reduction force. The authors analyse the correlation between the effect pro-duced by the channels in the movable platens on the axial stresses and the reduction force. The authors also describe the axial stresses distribution patterns in movable platens depending on the reduction force when producing 3 mm thick and 2,250 mm wide sheets from the 09G2S steel.
