What is a low-carbon ferromanganese? Low-carbon ferromanganese alloy composed mainly of manganese, iron composed of two elements, manganese steel production is the most frequently used a deoxidizer and alloying materials. It manganese ore as raw material in the blast furnace and electric furnace smelting steel. Manganese density 7.43g / cm3, a melting point of 1245. C, boiling point 2150. C. Manganese and has a great affinity for oxygen, capable of forming a stable manganese oxide and oxygen.
