Raw Materials

 

Iron Ore & Coal

Iron Ore & Coal

Description: A mineral that contains sufficient iron to be a commercial and viable source of the element used in steel mills. Coking coal permits the furnaces to reach temperatures of 2.000ºC.

Applications: Needed to produce pig iron.

Ferroalloys

Ferroalloys

Description: Compounded iron and steel products, in which the principal element is iron: ferrosilicon; ferromanganese, silicon manganese.

Applications: Is used as raw material to produce steel, stainless steel and other products.

Metallurgical Coke

Metallurgical Coke

Description: Is the basic combustion that is consumed in a high  furnace for the melting of iron. Coke is coal that has been degasified in a coke mill.

Applications: Provides the heat and gases necessary to melt and reduce the iron ore.

Pellets

Pellets

Description: Crude iron.

Applications: Mixed with scrap in an electric furnace produces steel.

Pig Iron

Pig Iron

Description: A key intermediate material in the integrated (converter-based) steelmaking process, pig iron is the product of smelting iron ore, coke and limestone in a blast furnace.

Applications: Pig Iron is used directly in the manufacture of steel. Merchant pig iron is sometimes used as a substitute for scrap in EAF steelmaking, when there is a need to control residuals.

Direct Reduced Iron

Direct Reduced Iron

Description: Direct Reduced Iron (DRI) – or sponge iron – is processed iron ore that is iron-rich enough to be used as a scrap substitute in electric furnace steelmaking. It is made by the reduction (removal of oxygen) of iron oxide (iron ore) at temperatures below the fusion point of iron.

Applications: As mini-mills expand their product abilities to sheet steel, they require much higher grades of scrap to approach the quality of output from integrated mills. DRI enables mini-mills to use iron ore without having a blast furnace. It serves as a low residual raw material and alleviates the mini-mills’ dependence on cleaner, higher priced scrap.

Manganese

Manganese

Description: Manganese is used in steel alloys to increase many favourable characteristics such as strength, hardness and durability. In fact steel cannot be produced without manganese; it is an essential ingredient in the process.

Applications: Steel becomes harder when it is alloyed with manganese. It has similar applications when alloyed with aluminium and copper. Hardened steel is important in the manufacture of construction materials like L-beams (24% of manganese consumption), machinery (14% of manganese consumption) and transportation products (13% of manganese consumption).

Hot Briquetted Iron

Hot Briquetted Iron

Description: Hot Briquetted Iron (HBI) is Direct Reduced Iron that has been processed into briquettes. Instead of using a blast furnace, the oxygen is removed from the ore using natural gas and results in a substance that is 91%–94% iron. Because DRI may spontaneously combust during transportation, HBI is preferred when the metallic material must be stored or moved.

Applications: Because of its high iron content and low residual levels, HBI can be used in almost every type of steelmaking operation. It has advantages over steel scrap due to its high bulk density and the very low content of undesirable chemical elements.

Ferrous Scrap

Ferrous Scrap

Description: Ferrous Metals are metals or metal alloys that contain the element iron which generally is melted and vacuumed to form new steel. All ferrous metals are magnetic and give little resistance to corrosion. We offer a great variety of ferrous scrap: HMS 1-100%, HMS 2, scrap rails, steel plate scrap, scrap pipe with moon cutting, cast iron scrap, shredded scrap.

Applications: As raw material to produce steel, stainless steel and other products. Scrap constitutes 100% of the raw material for an electric furnace.
