Q. How can we use Cereals?

Foundry cereal is finely ground corn flour or corn starch. It (0.25-2%) increases the green and dry strengths of the moulding sand. Since the cereal is organic, it is "burned out" when hot metal comes in contact with it. This gives rise to space for accommodating the expansion of silica sand at the surfaces of mould cavity, without buckling these. Because of their low density, about 1%is generally sufficient.

Saw Dust. It increases the gas permeability and deformability of moulds and cores, it must be dry. Instead of saw dust, one can use peat that contains about 70-73% volatile substance, not over 5 or 6% ash and up to 25-30% moisture.
