Method for producing cold-rolled steel strips

The invention discloses a method for producing cold-rolled steel strips. The method comprises the following steps of: performing krypton (KR) desulfurization treatment, converter dephosphorization-less slag decarburization and relative humidity (RH) light treatment on molten iron, and performing continuous casting to obtain a high-purity plate blank; heating the plate blank, performing rough rolling and precision rolling to obtain a hot-rolled plate, cooling the hot-rolled plate and coiling the hot-rolled plate into a hot-rolled coil; and performing cold rolling, annealing and flattening on the hot-rolled coil, and coiling the hot-rolled coil into a finished product. By the method for producing the cold-rolled steel strips, the cold-rolled steel strips which have high drawing property and good welding performance and can be used for flux-cored wires can be produced, the production requirement of the flux-cored wires is met, splash in the welding process is reduced, seams with good welding quality are obtained, and the automation level of welding is improved.
