A continuous casting machine ('block caster') is provided with chain-wise interlinking of mold block assemblies. Such chain-wise interlinking maintains the mold block assemblies essentially contiguous and is essential to provide operation of a continuous casting machine essentially free of mechanical noise. Each mold block assembly is elastically independently hinged by dual parallel hingepins, spaced-apart in the casting direction (x-axis), as the mold block assembly is carried between opposed, transversely (y-axis) spaced-apart guide rails of each carriage track. The elastic hinge means compensates for variation in block-to-block (centerline) distance caused by kinematic phenomena, including thermally induced variations in the dimensions of individual blocks as a function of their position in each track during operation. Guide rollers guided in generally horizontal guide roller-ways are afforded no measurable tolerance relative to their vertical displacement, when the roller-ways are off-set. Microslitted faces of mold blocks minimizes their distortion due to thermal cycles.
