Q. Can you explain about Fuel Oil and Dextrin?

Fuel Oil: It improves the mould ability of sand.

Iron Oxide: It develops hot strength.

Dextrin: It increases air setting strength, toughness and collapsibility and prevents sand from drying rapidly. During pouring of molten metal, it gasifies, thus producing extra space between the grains without any grain distortion.

Molasses: It is the by product of sugar industry. It enhances the bench life of sand and imparts high dry strength and collapsibility to moulds and cores. Due to high temperature in the mould; it develops CO2 which sets up a hardening action of the mould.
