Abstract
The present invention concerns a process and an apparatus for moulding ingots of ferro-alloys by chill casting in a cooled copper mould. The apparatus comprises: PA1 an ingot mould (1) of copper, which is formed from two mould halves (2), at least one of which comprises a plurality of impressions (10) of the ingots to be moulded, communicating with each other by way of ducts (11, 12) and opening in the upper part by way of an ingate (18), PA1 means (5) for cooling each mould half (2) by a heat exchange fluid, PA1 means (9) for bringing the two mould halves into contact and into sealing relationship, PA1 means for moving the two mould halves away from each other, and PA1 means (7, 8) for guiding the mould halves in their movement away from each other and in their movement of coming into sealing relationship.
