FEATURE:
FRX-39 is an economic non-carbonaceous exothermic anti-piping compound (APC).
FRX-39 is a medium sensitivity compound having a fairly high heat output.
FRX-39 is for general steel founder and large iron casting.
FRX-39 containing non-carbonaceous material to contaminate the feed metal.
APPLICATION:
Add FRX-39 to the liquid metal in the feeder or riser immediately after pouring. A layer
about 25 mm thick is recommended. The mould should be short poured by this amount.
If second feeding is needed after the exothermic reaction has ceased, the layer should be
broken and removed aside beforeaddition metal made. A freshlayer of FRX-39 should be
placed again after topping up has been completed.
