ABOUT

ABOUT US

STEEL AND

FOUNDRY INDUSTRY

BASIC PIG IRON

Is used in the production of steel and in iron castings. This grade has the least production control points of all the grades but has gained acceptance due to the economics verses scrap. The predominant use for this material is in the steel industry.

NODULAR PIG IRON

A high purity iron that is engineered for the production of Nodular, or Ductile irons. This material is graded by Phosphorus content and has an analysis that enables foundries to meet the critical application criteria of their customers.

HEMATITE PIG IRON

Foundry (haematite) pig iron that is available in a variety of grades depending on the Si content is primarily used in the production of grey iron castings in cupola furnaces.

ANTHRACITE

Anthracite, also known as hard coal, is a hard, compact variety of coal that has a submetallic luster. It has the highest carbon content, the fewest impurities, and the highest energy value of all types of coal and is the highest ranking of coals.

CALCINATED PETROLEUM COKE

Calcined petroleum coke (CPC) uses green petroleum coke as raw material. It is prepared by heating below 1400°C. The carbon content is about 98.5%. High conductivity and low resistance.

GRAPHITE

Archaically referred to as plumbago, is a crystalline form of the element carbon with its atoms arranged in a hexagonal structure. It occurs naturally in this form and is the most stable form of carbon under standard conditions. Under high pressures and temperatures it converts to diamond.

SILICON CARBIDE

Silicon carbide, also known as carborundum, is a semiconductor containing silicon and carbon. It occurs in nature as the extremely rare mineral moissanite. Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive.

FERRO ALLOYS

Ferroalloy refers to various alloys of iron with a high proportion of one or more other elements such as manganese (Mn), chrome (Cr), or silicon (Si). They are used in the production of steels and alloys.

Hot Briquetted Iron

Hot Briquetted Iron (HBI) is a premium form of DRI that has been compacted at a temperature greater than 650° C at time of compaction and has a density greater than 5,000 kilograms per cubic metre (5,000 kg/m3)

ENERGETICS

ENERGETICS

RUSSIAN STEAM COAL

Steam coal is a grade of coal used in electric power plants to generate steam to create electricity.

CAST IRON

PROGRAM
