Crude steel

CPC v2.1 Code: 4112

About crude steel

cpc code 4112 covers the production of crude steel, a fundamental material in the global manufacturing and construction industries. Crude steel is the primary output of the steelmaking process, serving as the building block for a wide range of steel products that are essential to modern infrastructure, transportation, and industrial development. As a key component of the broader metals and mining sector, the crude steel industry plays a vital role in supporting economic growth and development worldwide.

Production process

The production of crude steel typically involves two main processes: the blast furnace method and the electric arc furnace method. In the blast furnace method, iron ore, coal, and limestone are combined and heated to extremely high temperatures to produce molten pig iron, which is then further refined into crude steel. The electric arc furnace method, on the other hand, uses scrap metal as the primary input, which is melted using powerful electric currents to create crude steel.

Production inputs

The main inputs required for the crude steel industry include iron ore, coal, limestone, and scrap metal. Specialized machinery, such as blast furnaces, electric arc furnaces, and continuous casting equipment, are also essential for the steelmaking process. Additionally, the industry relies on a skilled workforce, including metallurgists, engineers, and technicians, to operate and maintain the production facilities.

Production outputs

The primary output of the crude steel industry is, of course, crude steel, which is then further processed and transformed into a wide range of steel products. These products may include 4113 Flat-rolled steel, 4114 Bars and rods of steel, 4115 Tubes, pipes and hollow profiles of steel, and 4116 Structural metal products, among others. The crude steel industry serves as a critical supplier to numerous downstream industries, including construction, automotive, machinery, and infrastructure development.
