Raw Materials

Steelcom has diversified its product range to become a supplier of cornerstone materials to the steel and energy industries. We structurally source and trade a complete range of raw materials such as:

Thermal Coal

thermalcoalCoal is a combustible sedimentary rock composed primarily of carbon, with volatile compounds and smaller quantities of other elements such as hydrogen, oxygen and sulphur. Its chemical composition and calorific value determine the quality and final use of different types of coal.

As a solid fuel, it is the largest source of energy for the production of steel and electricity worldwide.


Coking Coal

cokingcoalCoking coal is low-ash, low-sulphur bituminous coal suitable for the production of coke. It is also known as metallurgical coal.

It is used to produce metallurgical coke by baking in a vacuum oven until the volatile constituents are driven off and the fixed carbon and residual ash are fused together in a process called destructive distillation or coking.


Metallurgical Coke

metcokeCoke is a gray solid carbonaceous product with porous structure and very high caloric content derived from coking coal.

Coke is used both as a source of energy and as a reducing agent in the production of pig iron. Because of its high and stable burning temperature, its high crushing strength and its properties as a chemical reducing agent, it is a key element in the production of Iron and Steel. 90% percent of all coke produced is used in this industry.


Iron Ore

ironoreIron ore comes in the form of rocks and minerals from which Iron (Fe) can be economically recovered. It is the primary raw material in the production of pig iron and subsequently steel.

Raw iron ore can be transformed into “pellets” in a process that combines agglomeration and thermal treatment. The objective is to give the ore specific sizing and hardness properties that will be maintained during its transportation and use as feed in a blast furnace or Direct Reduction plant.

Metallurgical coke, iron ore fines or pellets and limestone are fed into a blast furnace to produce pig iron.


Pig Iron

pigironPig Iron is the solidified product of smelting iron ore and an intermediate raw material in the production of steel for which it requires further refining to reduce its content in Carbon and other impurities.

Pig Iron is re-melted in a basic oxygen furnace or electric-arc furnace into liquid form and refined by burning off excess carbon and other impurities and adjusting the alloy composition to produce steel.


Direct Reduced Iron

driDirect Reduced Iron (DRI) is a metallic material produced from direct reduction-oxidation of iron ore using a reducing gas (a chemical transformation process that removes Oxygen and Carbon without reaching the melting point of iron). It usually contains between 90 and 94% total iron and low amounts of residuals.

It is used in the production of steel, primarily in electric arc furnace mini-mills to increase their efficiency, among other advantages, by diluting the impurities contained in the scrap metal used in this process.


Hot Briquetted Iron

hotbriquettedironHot Briquetted Iron (HBI) is a premium form of Direct Reduced Iron that has been compacted to a density of over 5.000 kilograms per cubic meter.

Designed for ease of shipping, handling, and storage, it is used in steel-making as a substitute for higher priced scrap metal.
