Abstract:
In a process for continuously casting a metal strand by casting metal into a straight vertically oriented mold so as to form a straight strand and subsequently withdrawing from said mold said straight strand formed in said mold, bending said straight strand in at least one bending zone means along a transition curve to obtain a circular arc-shaped strand having a circular arc radius, guiding said circular arc-shaped strand along a circular arc guide having said circular arc radius, subsequently straightening said circular arc-shaped strand in a final straightening zone means along a final straightening zone transition curve to obtain a straightened strand, and finally extracting said straightened strand via an approximately horizontal straight guide the improvement comprisingforming said at least one bending zone means including a first transition curve and bending said strand along said first transition curve to a circular arc shape having a first circular arc radius, andproviding at least one consecutively arranged straightening zone means including a second transition curve and bending said strand along said second transition curve to impart on said strand a circular arc shape having a second circular arc radius larger than said first circular arc radius exhibited by said strand after being bent to said circular arc shape of said first transition curve.
