Blast Furnace Iron Trough Castable
Different types of refractory materials can be used as per the
types of iron troughs. Iron storing troughs in middle and large
scale steel mills usually adopt Al-Si-C series castable. Iron
trough and slag trough castable has high mechanical strength,
corrosion resistance, good flowability, and can be quickly dried.
Iron trough castable should also has excellent thermal shock

Alumina silicon carbide carbon castable is mainly used for the
casting of blast furnace iron trough. Alumina silicon carbide
carbon castable’s main materials are fused corundum(or sintered
corundum, special grade bauxite clinker), graphite contains 90%~95%
fixed carbon, silicon carbide and so on.
The development of self flow Al-Si-C castable brings lots of
convenience for casting construction. The unit refractory
consumption of per ton iron is significantly decreased with the
improvement of castable quality.
