CORE VALUES
Use
Converter deoxidizer and temperature increasing agent, etc.
Explanation
An alloy of iron and silicon, it is most often used as a decarburization agent for steelmaking, and is also widely used as an additive in the manufacture of silicon steel for transformers, acid-resistant alloys containing silicon, and acid-resistant cast iron.
Use
Removal of impurities and adjustment of components during the steelmaking process, etc.
Explanation
Description As an alloy of iron and chromium, it is divided into high carbon, low carbon, and ultra-low carbon ferrochrome according to the carbon content, and is mainly used as a chromium additive for special steel and special cast iron.
Use
Removal of impurities and adjustment of components during the steelmaking process, etc.
Explanation
It is classified into high-carbon ferromanganese, medium-carbon ferromanganese, and low-carbon ferromanganese according to its carbon content. It is also used as a manganese additive in high manganese steel and alloy steel.
Use
Removal of impurities and adjustment of components during the steelmaking process, etc.
Explanation
It is a material obtained by treating and refining rhododendron ore (MnCO3 is the main component) with sulfuric acid, and electrolyzing a sulfuric acid acidic manganese solution at high temperature using an insoluble anode and a stainless steel cathode and depositing it on the anode. It is made by a dry method. It is much higher in purity than metallic manganese. It is mainly used as a raw material for special alloys such as manganese bronze alloy or manganese steel that are corrosion resistant to seawater and mineral water.
Use
Aircraft jet engines, basic materials for submarine construction, etc.
Explanation
The density is about 57% of that of steel, so it is very light, has good mechanical strength, and even when a small amount is added to other metals to form an alloy, it has very good strength per weight and does not rust easily, so it is used for deoxidizing and denitrifying steel or containing titanium. It is used as a titanium additive for steel production, aircraft relations, seawater desalination equipment, and condenser for nuclear power generation.
Use
A rare metal used as an additive for stainless and special steel. It is used for alloy because it improves the strength of iron, resistance to abrasion and corrosion, and has good thermal conductivity. Basic materials for manufacturing stainless steel, casting, ferroalloy, etc.
Explanation
It is an iron and molybdenum alloy that is added in small amounts to steel to increase hardenability, toughness, and strength. It is used for stainless steel special steel, heat-resistant steel, and high-strength steel. In addition, ferromolybdenum (Mo65~70%) is used for steel, and molybdenum oxide is used for superheat-resistant alloy (super alloy) bulbs, anodes of electron tubes, grids, support wires and coil-shaped tungsten support rods.
Use
Impurity removal (deoxidation, desulfurization) and component adjustment during the steelmaking process, etc.
Explanation
The manufacturing method is the same as that of ferromanganese, and the raw materials are manganese ore with 20-35% of Mn and 30% of SiO2, coke, and iron scrap. is relatively large. It is a strong deoxidizer and an alloy additive for Mn and Si. It is low carbon (less than 1%) and has little change in carbon content by addition, so it is used in the manufacture of special steel and is also used as a raw material for low and medium carbon ferromanganese.
Use
Improves the corrosion resistance of steel products by removing oxygen contained in molten steel in a large amount by being put into the converter during the steelmaking process.
Explanation
It is used as a deoxidizer in converters.
Use

Explanation
It is used as a deoxidizer in converters.
Use
Low-cost alternative to ferrosilicon as converter deoxidizer and warmer
Explanation
It removes and extracts miscellaneous components from slag generated during silicon metal production.
