Cold-Rolled Coil

It is commonly used in the steel industry and is different from hot - rolled coils. It refers to the steel strip that is directly rolled into a certain thickness by rollers at room temperature and coiled into a complete roll by a coiler. Compared with hot - rolled coils, cold - rolled coils have a bright surface and high smoothness, but they will generate more internal stresses and are often annealed after cold - rolling. During the production process, since no heating is carried out, there are no defects such as pits and scale that often occur in hot - rolling. The surface quality is good and the smoothness is high. Moreover, the cold - rolled products have high dimensional accuracy, and the performance and structure of the products can meet some special usage requirements, such as electromagnetic performance and deep - drawing performance.

PRODUCT OVERVIEW

Overview

It is often used in the steel industry and is different from hot - rolled coils. It refers to the steel strip which is directly rolled into a certain thickness by rollers at normal temperature and then coiled into a complete roll by a coiler. Compared with hot - rolled coils, the surface of cold - rolled coils is bright and has a high finish. However, more internal stresses will be generated, so annealing treatment is often carried out after cold - rolling. Since there is no heating in the production process, there are no defects such as pits and scale which are common in hot - rolling. The surface quality is good and the finish is high. Moreover, cold - rolled products have high - dimensional accuracy, and the performance and structure of the products can meet some special application requirements, such as electromagnetic performance and deep - drawing performance.
