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.

Steel Slag - an overview | ScienceDirect Topics
Steel slag aggregates are fairly angular, roughly cubical pieces with a flat or elongated shape (as shown in Figure 2.13 [49]). They have a rough vesicular nature with many non-interconnected cells, which gives a greater surface area than smoother aggregates of equal volume. This feature provides an excellent bond with concrete binder.
