Cold rolled steel strip is rolled under recrystallization, but it is generally understood as rolling using materials rolled at room temperature. Aluminum cold rolling is divided into plate rolling and foil rolling. A thickness of 0.15~or above is called a plate, and a thickness of 0.15~or below is called a foil. Europe and America often use 3-6 continuous rolling mills as cold rolling equipment.
Cold rolled steel strip production is the precision machining process of steel strip rolling. The raw material for cold rolled steel strip is hot-rolled steel strip. To obtain high-quality cold-rolled steel strips, it is necessary to have good raw materials for hot-rolled steel strips. The control of the chemical composition, purity, and hot rolling process of steel has a significant impact on the microstructure and properties of the final cold rolled steel strip product; The external dimensions, shape, and surface condition of hot-rolled steel strips will directly affect the dimensional accuracy, shape, and surface quality of cold-rolled steel strips.
Controlling the chemical composition of steel during steelmaking is the foundation for ensuring the production of high-quality cold-rolled steel strips. The chemical composition of steel is closely related to the formability of the steel strip. The influence of carbon content in steel on the formability of steel strips is achieved by affecting the yield limit and plastic strain ratio of the steel. Carbon is one of the most significant elements in improving the strength of steel. As the carbon content increases, the yield limit increases, the plastic strain ratio decreases, and the formability deteriorates.

The smelting of carbon steel is usually carried out in converters and open hearth furnaces. Converter generally smelts ordinary carbon steel, while open hearth furnace can smelt various high-quality steels. The technology of oxygen top blown converter steelmaking has developed rapidly, and there is a trend to replace open hearth steelmaking. Injecting molten steel into the ingot mold yields various ingots. After being forged or rolled, steel ingots are processed into steel plates, steel strips, steel bars, and various sectional shapes. Carbon steel is generally used directly in the hot rolled state. When used in manufacturing tools and various machine parts, heat treatment is required according to the usage requirements; As for steel castings, most of them require heat treatment.
