Abstract

Flat metal products are pressure cast in a mould having two lateral walls each consisting of a support and of a graphite block as well as several spacers, including an upper spacer interposed between the blocks. The ends of the upper spacer and of the front spacer are inserted between two half-shells intended to receive a header of molten metal at the end of the cast. Elastic members carried by the supports exert during the cast, a clamping force of the half-sheels on the spacers. After the start of solidification of the slab, the clamping force is reduced by lateral jacks which eliminate any resistance to contraction of the slab and thus prevent the formation of cracks at the slab/header transition.
