Abstract
Abstract A metal ingot (pig) of a trapezoidal cross section having on each oblique side face at least one tooth and a recess for interlocking a plurality of the ingots in a row through similar teeth and recesses, said ingots being laid alternately so that the adjacent ingots are inverted relative to each other. The teeth and recesses prevent adjacent ingots in one row from longitudinal and transverse displacement.
