Complex modifiers produced by rolling of powder mixtures for iron–carbon steels

Powder Metallurgy and Metal Ceramics Aims and scope

The paper examines the rolling of powder modifying mixtures to produce complex composite modifiers (CCMs). The mixtures contain hard-to-mold components constituting the major fraction (up to 70 wt.%) of complex modifiers. It is of primary importance to produce sufficiently strong and moldable billets in the form of modifier strips. The rolling parameters and the ratio of hard-to-mold and plastic materials in CCMs are examined to maximally increase the content of the main modifying components and thus to decrease the amount of CCM introduced into liquid metal to modify cast iron. Production tests show that rolled CCMs show good recovery, have a stable effect, and permit the production of high-strength cast iron without chill.
