flat iron from slag

A mechanistic study of the formation of slags from iron ...

1996-6-1  The mechanism of slag formation by minerals from iron-rich coals was investigated in the reproducible environment of a laboratory burner. Alumina plates were used as substrates on which the particles were deposited. To simulate the highly reducing atmosphere of a cyclone-type flame, the burner was fired with large excess of CO.
