Granulated slag (slag sand) from the manufacture of iron or steel
HS v2022 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 raw material for various applications. Granulated slag is an important component in the production of cement, concrete, and other building materials, contributing to the sustainability and efficiency of the construction sector.
Production process
Granulated slag is produced by rapidly cooling molten slag, a waste product generated during the smelting of iron ore. The molten slag is quenched with water or air, causing it to solidify into a glassy, granular material. This rapid cooling process preserves the chemical and physical properties of the slag, making it suitable for a wide range of industrial uses.
Production inputs
The primary input for the production of granulated slag is the molten slag generated during the iron and steel manufacturing process. This slag is a complex mixture of silicates, aluminates, and other mineral compounds that are separated from the molten metal. In addition to the raw slag, the production of granulated slag requires access to water or air for the quenching and cooling processes, as well as specialized equipment such as granulators and cooling systems.
Production outputs
Granulated slag produced under HS code 2618 is primarily used as a raw material in the production of cement and concrete 2523 Portland cement, aluminous cement, slag cement, supersulfate cement and similar hydraulic cements, whether or not coloured or in the form of clinkers. It can also be used as a substitute for sand or gravel in various construction applications, as well as a component in the manufacture of 6815 Articles of stone or of other mineral substances, including articles of peat, not elsewhere specified or included. The versatility of granulated slag makes it a valuable resource in the construction and infrastructure industries.
