FURNACES AND REFRACTORIESModern Eq
A furnace is an equipment used to melt metals for casting or to heat materials to change their shape (e.g. rolling forging) or properties (heat treatment). Since flue gases from the fuel come in direct contact with the materials the type of fuel chosen is important. For example some materials will not tolerate sulphur in the fuel.
