The forming rolls are mainly hot rolled coils and cold rolled coils. Hot rolled coil is a processed product before re-crystallization of the billet. Cold rolled coil is the subsequent processing of hot rolled coil. The steel coil generally has a weight of about 15-30T. This year, China's hot rolling production capacity has been expanding continuously. There are already dozens of hot rolling production lines, and some projects are about to be built or put into production.
Steel coils are sold mainly for large customers, and general users do not have unwinding equipment or limited usage. Therefore, the subsequent processing of steel coils will be a promising industry. Of course, the current large steel mills have their own open and flat projects.
