Abstract
PURPOSE: To obtain a low-C Cr-Fe alloy from low grade Cr ore by carrying out incomplete reduction with C under specified conditions so as to decarburize the reduction product with the residual oxide in the solid reduction of the ore contg. Cr and Fe oxides in a vacuum.
CONSTITUTION: Starting materials contg. Cr and Fe oxides are blended in the ratio of Cr/(Cr+Fe)<0.6. Simultaneously, to the materials are added carbon as a reducing agent in an amount 0.7W0.9 time as much as the stoichiometrically necessary amount, a flux such as alkali metallic fluoride or oxide and a binder. They are molded in the form of lumps and subjected to reduction and decarburization by heating at ≥1,250°C in <1Torr vacuum at the beginning of the heating. The reduced and decarburized pellets are pulverized and magnetically separated in a dry state to obtain a powdered Fe-Cr alloy.
