摘要：A method of widening the width of a continuously cast strand, especially a caststeel strand, comprising the steps of casting a strand in an adjustable continuous castingmold having a first pair of oppositely situated short sides and a second pair of oppositelysituated long sides defining therebetween the mold compartment, wherein at least oneof the short sides of the mold can be moved during the casting operation. According tothe invention, the short side of the mold, during a first stage, is moved away from thecontinuously cast strand, by rocking or pivoting the same about its lower end region andis brought out of a starting position into an inclined displaced position, then during asecond stage this short side is displaced horizontally, in a direction substantially paralleland away from the cast strand, and then during a third stage such short side is movedaway from the strand out of the horizontally displaced position into an end position bypivoting or rocking such short side about its upper end region. The displacement speedwhich is effective during the second stage is dependent upon the relevant prevailingcasting speed and chosen such that there is ensured for contact of the cast metal withthe entire, imbued surface of such short side.
