Foundry
Grade and Basic Grade Pig Iron
Foundry and Basic
(or steel-making) Grade Pig Irons are some of the principal charge
materials for the production of gray iron. These pig irons come with
certified analysis, consistent and uniform shape, and good recovery
of carbon and silicon. Pig iron has a lower melting point than that
of steel scrap. A lower melting point combined with a denser charge
make-up result in lower energy requirements and faster melting time
when compared to that of an all steel charge make-up. Miller and Company
has extensive experience in assisting foundries with reviewing and
establishing proper charge make-up to include the use of Foundry Grade
or Basic Pig Iron. Miller and Company has contacts throughout the world
and is able to provide products from a variety of sources.
