ABSTRACT:
An anti-oxidative agent for molten metal containing at least nonylphenol polyoxyethylene ether, organic amine, phosphoric acid, and phytic acid. A method of preparing the anti-oxidative agent for molten metal, by a) heating an organic amine to between 60 and 100° C., adding a nonylphenol polyoxyethylene ether, and stirring for between 3 and 5 min to yield a mixture; and b) cooling the mixture to between 30 and 100° C., and adding phosphoric acid and phytic acid and stirring for between 10 and 15 min. The anti-oxidative agent for molten metal has no flash point and spreads quickly on the liquid surface, providing high reduction efficiency at lost cost.
