Cold rolling of narrow strip
NACE v2.1 Code: C24.32
About cold rolling of narrow strip
NACE code 24.32, 'Cold rolling of narrow strip', represents a crucial segment of the metal manufacturing industry. This process involves the transformation of hot-rolled steel into thinner, more uniform strips through a series of controlled rolling operations. The cold rolling technique is essential for producing a wide range of metal products, from automotive components to household appliances, making it a vital contributor to various downstream industries.
Production process
The cold rolling of narrow strip typically begins with the receipt of hot-rolled steel coils or sheets. These raw materials are then fed into specialized rolling mills, where they are passed between a series of rollers under high pressure. This process reduces the thickness of the metal while improving its surface finish, dimensional accuracy, and mechanical properties. The controlled temperature and tension during the rolling operation allow for precise control over the final dimensions and characteristics of the cold-rolled strip.
Production inputs
The primary inputs for the cold rolling of narrow strip industry include hot-rolled steel coils or sheets, which serve as the raw material. Additionally, the process requires specialized rolling mills, equipped with powerful motors and precision-engineered rollers, to perform the controlled reduction in thickness. Lubricants and coolants are also essential to facilitate the rolling process and maintain the quality of the final product.
Production outputs
The primary output of the cold rolling of narrow strip industry is cold-rolled steel strip, which is then used as an input for a wide range of downstream industries. These include the 25.11 Manufacture of metal structures and parts of structures, 28.11 Manufacture of engines and turbines, except aircraft, vehicle and cycle engines, and 29.32 Manufacture of other parts and accessories for motor vehicles. The cold-rolled steel strip produced in this industry is a crucial component in the manufacturing of various metal products, contributing to the overall efficiency and competitiveness of these related industries.
