Exothermic ferromanganese

Abstract

No chilling effect and higher recovery are the two chief advantages which have turned steel producers toward exothermic ferroalloys—a blend of an oxidizing agent, a reducing agent, and a conventional ferroalloy. The reducing and the oxidizing agents, upon contact with the molten metal, produce sufficient heat to deliver the ferroalloy in molten state. Satisfaction has been such that use of exothermic ferroalloys has greatly multiplied since exothermic ferrochrome was introduced in 1939 by the Chromium Mining & Smelting Corp.

Exothermic ferromanganese has found the broadest applications of this group of alloys and was the subject of a special session at this year’s National Open Hearth Conference. Below is presented an article on production at the Electro Metallurgical Co., and three conference reports on the use of exothermic ferromanganese: at Youngstown Sheet & Tube, Bethlehem Steel, and U. S. Steel.
