Zusammenfassung:	Method and apparatus for producing non-friable cast alloy shapes by controllably cooling them after casting. The alloy shapes are gravity fed through an annealing insulated tower at a controllable speed proportional to the rate and degree of cooling required to produce the optimum characteristics for the particular alloy shapes cast, such alloy shapes being ferrosilicon, silico-manganese, ferromanganese and the like.
