TIN PLATE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/082755
Kind Code:
A1
Abstract:
The present application relates to the technical field of alloy materials, and in particular, to a tin plate and a manufacturing method therefor. According to the provided manufacturing method for the tin plate, a component design of low-carbon aluminum killed steel is employed; 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 leveling 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. In addition, the amount of alloy tin is reasonably controlled to meet the requirements for stamping formability, pressure resistance and surface glossiness of an aerosol can top cover, so that the tin plate has simple components, the process is simple and easy to implement, and the production cost is low.
