Abstract
Improvements in the risers for the casting of metals under gas pressure, particularly in devices for low pressure casting, consisting of a tube made of several concentric shells, submerged at its lower end in a metal fusion and whose central zone, located between two wraps, is aerated by a hole, at least leading to the outside, characterized in that the central area is constituted by an air slit (26) and the two envelopes (22,23,32,33) that limit the air gap is constituted by non-metallic refractory material, permeable to gas or which becomes permeable to gas as a result of use, and joined together, stagnant to the melting at least at the lower end of the riser tube ( 6) (Machine-translation by Google Translate, not legally binding)
