Pig iron and spiegeleisen in pigs, blocks or other primary forms
CPC v2.1 Code: 41111
About pig iron and spiegeleisen in pigs, blocks or other primary forms
cpc code 41111 covers the production of pig iron and spiegeleisen, which are essential raw materials for the steel industry. Pig iron is the primary product obtained from the smelting of iron ore, while spiegeleisen is a ferroalloy containing manganese and other elements. These materials serve as the building blocks for a wide range of steel products, making them a crucial component of the global manufacturing and construction sectors.
Production process
The production of pig iron and spiegeleisen typically involves the use of blast furnaces. Iron ore, coke, and limestone are fed into the top of the furnace, while hot air is blown in from the bottom. The intense heat and chemical reactions within the furnace reduce the iron ore, separating the molten pig iron from the slag. The pig iron is then cast into molds or blocks for further processing, while the slag is removed as a byproduct.
Production inputs
The main inputs required for the production of pig iron and spiegeleisen include iron ore, coke (a processed form of coal), and limestone. These raw materials are essential for the reduction and smelting process that takes place in the blast furnace. Additionally, the industry relies on specialized equipment such as blast furnaces, casting machinery, and transportation infrastructure to move the raw materials and finished products.
Production outputs
The primary output of cpc code 41111 is pig iron and spiegeleisen, which are then consumed by 41112 Ferro-alloys and 41121 Steel in ingots or other primary forms producers. These materials are the foundation for the production of a wide range of steel products, including construction materials, automotive components, and industrial machinery, making them crucial inputs for numerous other industries.
