PELLETIZED COMPOSITION FOR MOLTEN METAL DE-OXIDATION

摘要

One aspect of the present invention relates to compositions of a pelletized form which are well suited for use as inoculants in the manufacture or casting of molten metals. A further aspect of the invention relates to a method of making such pelletized compositions from waste materials which bear silicon carbide or both silicon carbide and silicon.

主权项

1. A pelletized composition made according to a method comprising the steps of:
(a) providing a material containing moisture and at least: (i) silicon carbide or (ii) both silicon carbide and silicon; (b) heating said material under a vacuum to dry said material to a total moisture content of less than fifteen percent by weight; (c) mixing said material with a binder to form a mixture; (d) pelletizing said mixture to agglomerate said particles to form a plurality of discrete pellets of at least one desired size, each of said pellets including a plurality of said particles, and (e) hardening said binder to strengthen said pellets.
