Batch Annealed CR production is a finishing process for steel strip rolling. The raw material of Batch Annealed CR is hot rolled steel strip. To obtain high-quality Batch Annealed CR, good hot-rolled steel strip raw materials must be available. The chemical composition, purity and hot-rolling process control of the steel have a great impact on the structure and performance of the final Batch Annealed CR product; the outer dimensions, shape and surface condition of the hot-rolled steel strip will directly affect the Batch Annealed CR Dimensional accuracy, plate shape and surface quality.

Controlling the chemical composition of steel during steelmaking is the basis for ensuring the production of high-quality Batch Annealed CR. The chemical composition of steel is closely related to the forming performance of the steel strip. The carbon content of the steel affects the formability of the steel strip by affecting the yield limit and plastic strain ratio of the steel.
