The molding coils are mainly hot-rolled and cold-rolled coils. Hot-rolled coil is a processed product before billet recrystallization. Cold rolled coil is a subsequent processing of hot rolled coil. The general weight of a steel roll is around 15-30t. This year, China's hot rolling production capacity continues to expand, there are already dozens of hot rolling production lines, and some projects are about to be built or put into operation. Steel rolls into rolls mainly for large customers, the general user does not have unwinding equipment or limited dosage. Therefore, the subsequent processing of steel rolls will be a very promising industry. Of course, the larger steel mills at the moment have their own unwinding and leveling projects.
