Steel coils are formed by hot-pressing and cold-pressing of steel into coils. In order to facilitate storage and transportation, various types of processing (for example, processing into steel plates, strips, etc.) are facilitated.
The forming rolls are mainly hot rolled coils and cold rolled coils. Hot rolled coil is a processed product before recrystallization of the billet. Cold rolled coils are the subsequent processing of hot rolled coils. The general weight of steel coils is around 15-30T. This year, China's hot rolling production capacity has been continuously expanded, there are already dozens of hot rolling production lines, and some projects are about to be built or put into production. Subsequent processing of steel coils will be a promising industry.
