Abstract:
PCT No. PCT/FR97/00546 Sec. 371 Date Jan. 22, 1999 Sec. 102(e) Date Jan. 22, 1999 PCT Filed Mar. 27, 1997 PCT Pub. No. WO97/37792 PCT Pub. Date Oct. 16, 1997This mold consists of a cooled mold body (1), made of copper or a copper alloy, on which sits a refractory feed head (2) and a purge slit (8) is made at the interface between said mold body and said feed head, via which a stream of a waste inert gas is injected around the internal perimeter of the mold. The slit is supplied via a plenum chamber (13) made within the mold, the plenum chamber being itself supplied with gas via inlets (12) which connect it to a pressurized-gas supply (20). The injection slit (8) is segmented around the mold perimeter with the aid of separating means (21) which also segment the plenum chamber into compartments (13', 13'', etc.) which are juxtaposed around the perimeter of the mold so that an inlet (12) runs out into each compartment thus formed. Thus, a plurality of elementary circuits (12'- 13''- 8'), which are mounted "in parallel" with respect to a single pressure chamber (20), are produced so that, overall, the injection of gas around the perimeter of the mold becomes insensitive to local perturbations such as local variations in the thickness of the slit.
