Question:
How can I measure contact angle between molten steel and
sand mould?
Replies:
Without sounding flippant, the answer is,"With great difficulty!!" You are
talking about high temperatures, reactions of molten metals with the
atmospheric gases, and a host of other experimental difficulties. Even
getting the sand mold and the molten steel to the same temperature could be
daunting.
And the contact angle, even on the easiest of systems, is of questionable
reliability because small amounts of impurities on the surface of the liquid
phase can cause wildly different results.
