Ferrochrome
Ferrochrome (FeCr) is an iron alloy composed of chromium, iron, carbon and a small amount of impurities. It is one of the main alloying agents used in the steel industry. Adding ferrochrome to steel can significantly improve the oxidation resistance of steel and increase the corrosion resistance of steel.
Ferrochromium, as an important alloy additive in the steelmaking industry, is divided into four categories and 12 grades: high-carbon ferrochromium, medium-low carbon ferrochromium and micro-carbon ferrochromium according to its carbon content. Among them, medium, low and micro carbon ferrochrome account for about 3/4 of the required amount. Microcarbon ferrochromium is mainly used to produce stainless steel, acid-resistant steel and heat-resistant steel, while medium and low carbon ferrochromium is mainly used to produce medium and low carbon structural steel, chromium steel and alloy structural steel.
Ferrosilicon
Ferrosilicon or ferro silicon is an iron alloy composed of iron and silicon. Ferrosilicon is an iron-silicon alloy made from coke, steel scraps, quartz (or silica) as raw materials and smelted in an electric furnace. It is widely used in steel industry, foundry industry and other industrial production.
Ferromanganese
Ferromanganese alloy is an iron alloy composed of manganese and iron. The raw materials for making Ferro Manganese are generally manganese ore, coke, and lime containing manganese element, which are melted and fully reacted in a high-temperature environment and smelted.
Ferromanganese is divided into four categories based on carbon content: high carbon ferro manganese ( carbon content 7.0%-8.0% ), medium carbon ferro manganese ( carbon content 1.0%-2.0% ), low carbon ferro manganese ( carbon content 0.2%-0.7% ), and micro carbon ferro manganese ( carbon content 0.05%-1.0% ). The blast furnace ferro manganese is mainly utilized in the manufacturing of tool steel and wear-resistant high-manganese steel, which is classified as high-carbon ferro manganese.
Manganese-silicon alloy
Manganese-silicon alloy is an alloy composed of manganese, silicon, iron, a small amount of carbon and other elements. It is an iron alloy with a wide range of uses and large output. It has the advantages of low melting point, large particles, easy to float, and good deoxidation effect. It is a commonly used composite deoxidizer in steelmaking. It is also a reducing agent for the production of low carbon ferromanganese and the production of metallic manganese by electrosilicothermal method.
Silicon carbon alloy
Silicon carbon alloy is a new type of alloy used in steel making and casting. It can replace ferrosilicon, silicon carbide, and recarburizers, reduce the amount of deoxidizer, and is used in the deoxidation alloying process of converter smelting with stable effects. the chemical composition, mechanical properties and internal control quality of steel are superior to traditional processes. It has the advantages of improving the quality of molten steel, improving product quality, improving product new capabilities, reducing the amount of alloy added, reducing steelmaking costs, and increasing economic benefits.
