Fluidity spiral

Pouring sample with horizontally arranged, spiral flow channel (Figure 1).

In general, the outfeed length depends on the chemical composition of the respective casting alloy and the casting temperature. Fluidity spirals are well suited for analyses with respect to general castability of alloy but are unsuitable for monitoring of process safety in melting operation.
