Granulated slag (slag sand) from the manufacture of iron or steel
HS v2017 Code: 2618
About granulated slag (slag sand) from the manufacture of iron or steel
HS code 2618 covers granulated slag, also known as slag sand, which is a byproduct of the iron and steel manufacturing process. This material plays a crucial role in the construction and infrastructure industries, serving as a valuable input for various applications. As a sustainable and cost-effective alternative to traditional aggregates, the production and utilization of granulated slag contribute to the overall efficiency and environmental responsibility of the metal processing sector.
Production process
Granulated slag is produced by rapidly cooling molten slag, a waste material generated during the smelting of iron ore. The molten slag is quenched with water or air, causing it to solidify into a glassy, granular form. This process, known as granulation, results in a material with a consistent, uniform particle size and shape, making it suitable for a wide range of construction and industrial uses.
Production inputs
The primary inputs for the production of granulated slag include iron ore, coal, and limestone, which are the key raw materials used in the iron and steel manufacturing process. Additionally, the production requires specialized equipment, such as slag granulators, cooling systems, and material handling infrastructure, to efficiently transform the molten slag into the desired granular form.
Production outputs
Granulated slag produced under HS code 2618 finds numerous applications in the construction industry, serving as a substitute for 2517 natural aggregates in concrete, asphalt, and other building materials. It is also used as a supplementary cementitious material, partially replacing traditional Portland cement in the production of concrete. Furthermore, granulated slag may be utilized in the manufacture of 6815 non-metallic mineral products, such as insulation materials and abrasives.
