Abstract
In a mold cavity and/or in horizontal cooling zones, upstream- and downstream-side gears are drivingly coupled to each other through an endless-track-like member to which the tensile force is exerted by a tensioner, so that gaps between the adjacent block molds can be eliminated and therefore intrusion and leakage of a cooling liquid and melt are prevented.
