Abstract

A centrifugal caster arrangement including: a motor driven centrifuge arm and a weight arm connected to the centrifuge arm, with both arms being rotatable about a vertical axis. A counterweight is permanently fixed to the weight arm and a casting chamber is connected to the centrifuge arm. A melting crucible is disposed in the casting chamber. A plurality of muffle sets is provided with each muffle set including an exchangeable muffle cage and an associated casting muffle inserted therein. The casting chamber is provided with a region for mounting one of the muffle sets. Each exchangeable muffle cage is matched to its associated casting muffle according to size and weight so that the total weight of each respective muffle set is such magnitude that when each respective muffle set is mounted in the casting chamber and rotated about the vertical axis the centrifuge arm is in balance with the weight arm and the permanently fixed counterweight.
