A method for controlling the individual drives of a sheet strand casting - much rollers machine for metal, in particular for steel, and drive arrangement for this purpose,

摘要

A method for continuous casting of metallic strands which provides a maximum compressive stress to the strand at the precise bending point of the strand guide. In this manner, continuous casting speeds of greater than 0.8 m/min. can be utilized without the otherwise present potential for ruptures and tears. Pairs of supporting rollers are spaced along the strand guide. A bending point is defined as the precise point where the arcuate section of the strand guide becomes the linear section of the strand guide. It is at that bending point that the compressive forces on the cast metallic strand are maximized by the selected driving of the supporting rollers, located downstream of the bending point. The number of supporting rollers located upstream of the bending point is not less than twice the number of supporting rollers located downstream of the bending point.
