CONTINUOUS CASTING AND PLANT TO THIS END Russian patent published in 2014 - IPC B22D11/128 B22D11/14 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, in particular, to continuous casting. This process comprises feed of liquid metal into ingot mould, drawing of ingot from the mould, flushing and bending in radius decreasing from maximum to minimum. Ingot displacement without deformation is performed in arc while ingot unbending occurs with increase in radius to maximum. Drawing of the ingot is carried out in path described by brachistochrone that meets the conditions of minimum power costs of its flushing. Ingot bending conditions are set in compliance with radius decrease algorithm and with allowance for tolerable deformation at the last point of bending. Proposed unit comprises ingot mould, section of roller guidance and draw-and-straighten devices that make a process channel with axis described by brachistochrone. The number of rollers and their pitch at bending section are set in compliance with increase in accumulated deformation in drawing path and with allowance for deformation increase constriction with admissible value at final bending section.

EFFECT: stable high quality of finished billets, longer life of guidance hardware.
