Tundish flux is an ideal covering flux for ladle and tundish due to its high refractoriness, good thermal stability, high volume expansion,thermal shock resistance and good wear ability.
Tundish Covering agent: 1)Thermal Insulation. 2) Insolated from the air, Prevented Secondary Oxidization 3) Adsorbed impurity 4) fast spread the surface
Tundish Covering agent
Synthetic slag consists of prepared mixture of several individual oxides which is used during secondary steelmaking to assist the steel treatment in the ladle from the viewpoint of effective refinement. Synthetic slag practice is normally used to obtain clean steels and also for the desulphurization of the liquid steel.
