Ferromanganese alloy

INTRODUCTION

An alloy made from manganese ore. For smelting different types of manganese ferroalloys, the requirements for manganese content and ferromanganese ratio in ores are shown in the table: iron content of ores used for steelmaking pig iron, manganese containing pig iron and specularite is not limited, and the total content of manganese and iron in ores is better to reach 40%~50%.
