摘要

The composition for coating of a surface intended to be exposed to a metal melt is disclosed. The composition essentially consists of:
8-18 wt-% of a refractory component;
50-75 wt-% of solvent, preferably water;
10-20 wt-% of an inorganic binder;
0-10 wt-%, preferably 2-10 wt-%, of an organic binder;
0.3-7 wt-%, preferably 2-6 wt-%, more preferably, 3-5 wt-% of pyrite;
and optionally up to 10 wt-%, preferably up to 5 wt-%, of additional additive or additives. The composition results in a coating on a surface, which coating is able to reduce the dissolved elemental magnesium content in a metal melt to which the surface is exposed.
