Abstract

Two fixed heads are used to lubricate a split-mold. The heads do not interfere with the movements of the mold and are effective to inject a jet of a gas that forms a powdery carbonaceous material. When the mold is open, the injection axis of each head is just about in line with the axis of the associated half-casting.
