Medium Carbon Ferro Manganese

Introduction

Medium Carbon Ferro Manganese is an iron alloy composed of manganese and iron, and the carbon content is about 1.0-1.5%. It is one of the categories of ferromanganese. It is often used as a deoxidizer and alloy additive in the field of metallurgy and casting, and is an important metallurgical raw material. In steelmaking, ferromanganese is used as a deoxidizer and alloy additive, and is the most used ferroalloy. Before smelting, manganese carbonate ore needs to be roasted, and powder ore needs to be sintered and agglomerated. Generally, ore with high iron and phosphorus content can only be used in combination, or through selective reduction to obtain manganese-rich slag with low iron and low phosphorus. Coke is used as a reducing agent during smelting, and some factories also use lean coal or anthracite. The auxiliary raw material is mainly lime, and silica is generally added when smelting manganese-silicon alloys.

Product Usage

1.Medium Carbon Ferro Manganese is used as deoxidizer and alloy additive in steelmaking. The manganese ore used for smelting ferromanganese generally needs 30~40% manganese, the ratio of manganese to ferromanganese is greater than 7, and the ratio of phosphorus to manganese is less than 0.003.

2. The addition of ferromanganese in the foundry industry can be used as an inoculant and a spheroidizing agent, which can effectively prevent the formation of carbides, promote the precipitation of graphite, and greatly shorten the spheroidization time.

Features

Medium Carbon Ferro Manganese is mainly an alloy composed of manganese and iron. Ferromanganese is the most commonly used Oxygen scavenger and alloy material in steelmaking. It is made of manganese ore, which is smelted in blast furnaces and electric furnaces. The density of manganese is 7.43 grams per cubic centimeter, with a melting point of 1245 ° C and a boiling point of 2150 ° C. Manganese has a strong affinity for oxygen and can form stable manganese oxide with oxygen. In addition, as an alloying element additive, ferromanganese can improve the hardness, ductility, toughness, and wear resistance of steel. It is widely used in structural steel, Tool steel, stainless steel heat-resistant steel, wear-resistant steel and other alloy steels. Manganese can also desulfurization and reduce the harmful effects of sulfur.

Background

In the steel and stainless steel manufacturing process, ferromanganese powder is widely used, and the consumption is 0.8-0.9% of the steel output, which accounts for 85-90% of the total demand for manganese. Manganese in ferromanganese alloy accounts for 60%-82%, and the sum of manganese and iron accounts for about 92%, that is, iron accounts for 10%-32%. Traditionally, manganese ore, iron ore, limestone, quartz sand and carbonaceous reducing agent are mixed and batched according to the desired grade of ferromanganese powder. In industrial production, relying on iron ore to adjust the ratio of manganese to iron, and limestone and quartz sand to adjust the alkalinity of slag, not only requires the composition of the produced manganese ore to be stable, but also consumes additional additives such as iron ore and limestone.
