Product Description

Product Introduction

Ferromanganese, an alloy mainly of Fe and Mn with other elements, is produced via smelting in electric arc furnaces using manganese ore, coke, and flux. Its carbon content (over 2% for high - carbon, 0.5% - 2% for medium - carbon, under 0.5% for low - carbon) is adjustable. It's a hard, brittle, metallic - lustered solid with high density and good conductivity, having 60% - 80% Mn; higher Mn content boosts its steel - making strengthening effects.

Product Application

1. Steel - making Industry

• Deoxidizer: In the steel - making process, oxygen is often present in molten steel, which can cause defects such as porosity and brittleness in the final steel products. Ferromanganese is added to the molten steel as a deoxidizer. Manganese in ferromanganese reacts with oxygen in the steel to form manganese oxide (MnO), which floats to the surface of the molten steel as slag and can be removed. This helps to purify the steel and improve its quality.
• Alloying Agent: Ferromanganese is a crucial alloying agent for steel. Manganese can significantly improve the strength, hardness, and wear resistance of steel. For example, in the production of high - strength low - alloy (HSLA) steels, adding ferromanganese can enhance the steel's ability to resist deformation and fatigue. In tool steels, manganese helps to increase the hardenability of the steel, allowing it to be heat - treated to achieve high hardness and cutting performance.

2. Cast Iron Production

• Inoculant and Alloying Agent: In the production of cast iron, ferromanganese can be used as an inoculant. It promotes the formation of graphite in a more uniform and fine - grained structure, improving the mechanical properties of cast iron, such as its strength and ductility. Additionally, as an alloying agent, manganese in ferromanganese can increase the resistance of cast iron to wear and corrosion. For example, in the production of ductile iron, ferromanganese helps to control the morphology and distribution of graphite nodules, resulting in better - performing cast iron products.

3. Ferroalloy and Special Alloy Production

• Ferromanganese serves as a raw material for producing other ferroalloys and special alloys. It can be combined with other metals like nickel, chromium, and molybdenum to create high - performance alloys with specific properties. For instance, in the production of stainless steel alloys, ferromanganese is used in combination with chromium and nickel to enhance the steel's corrosion resistance, strength, and other characteristics. These special alloys are widely used in various industries, including aerospace, automotive, and chemical engineering.

4. Foundry Industry

• In the foundry process, ferromanganese can be used to adjust the chemical composition of molten metals. It helps foundries to produce castings with the desired mechanical properties, such as increased hardness and wear resistance. This is especially important in the production of heavy - duty castings for machinery, construction equipment, and mining equipment.
