Abstract

A manufacturing method for a tin plate including a component design of low-carbon aluminum killed steel; under the condition of not increasing the alloy content and the production control difficulty, the content of elements such as C, Mn, Al and N in the tin plate is designed, and corresponding hot rolling, cold rolling, annealing and leveling processes are used; the strengthening effects of conventional elements, carbon and manganese, are fully utilized, aluminum nitride precipitation control in hot rolling is taken into account, a proper cold rolling reduction rate is selected, the ferrite grain size and cementite precipitation in steel are controlled by means of continuous annealing and over-aging treatment, and a specific temper rolling process is used, so that a tin plate having small strength and hardness fluctuations, a high elongation rate and a short yield plateau is produced.
