An apparatus for the manufacture of strands of molten metal, in particular nonalloyed and alloyed steels, by continuous casting, comprising a mold for continuously casting a strand and means for simultaneously withdrawing the cast strand from the mold. The cast strand which exits from the mold is in a partially solidified state and has a molten core. The withdrawing means comprise a pair of spaced grooved rollers which define a box-pass therebetween. The bottom of the groove of each roller includes a convexedly curved portion, the camber of convexity of which amounts to 10-25 percent of the height of the box-pass. Pressure producing means are operatively connected to the pair of grooved rollers. This pressure producing means being selectively variable in applying pressure at ratios ranging from 1:4 to 1:8.
