Embodiment Construction

[0055] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0056] Table 1 is the alloy composition of Examples 1-10 of the present invention and Comparative Examples 1-8, Table 2 is the manufacturing process parameters of Examples 1-10 of the present invention and Comparative Examples 1-8, and Table 3 is Examples 1-8 of the present invention 10 and comparative examples 1-8 performance after baking, note: the baking process of the steel plate is 210 ℃ for 30 minutes. The mechanical properties are measured according to the JIS5 standard processing tensile sample, Rp0.2 is the yield strength value based on the stress value of 0.2% residual deformation, A% is the elongation at break, and the measuring gauge length is 50mm.

[0057] Depend on figure 1 It can be seen that with the prolongation of the annealing time of the strip steel, the degree of recrystallization of ferrite in the steel of the present invention g...

Abstract

The invention discloses a high-strength tin-plated raw plate and a manufacturing method thereof. The tin-plated raw plate comprises the following chemical components in percentage by weight: 0.08%-0.14% of C, 0.2%-0.5% of Mn, 0.03%-0.05% of Al, 0.01%-0.02% of P, 0.006%-0.015% of N and the balance Fe and Fe impurity elements, and the elements need to meet the following relationship simultaneously:50C+10Mn+50P+100N is not less than 8.5% and not greater than 12.75%. According to the manufacturing method disclosed by the invention, a one-step cold rolling process is adopted, an annealing temperature T in a continuous annealing step is controlled to be not less than 550+5*10<4>*(C-0.08%)+5x10<3>*(Mn-0.20%) and not greater than 630+5*10<4>*(C-0.08%), the unit is DEG C, and the tin-plated raw plate with a yield strength of not less than 500MPa and an elongation of not less than 5% after bake-hardening can be manufactured; and the manufacturing method is applicable to produce products with requirements on formability, such as three-piece can bodies, easy-open caps and twist-off caps.

Description

technical field [0001] The invention belongs to the field of steel for packaging, and in particular relates to a high-strength tin-plated raw plate and a manufacturing method thereof, in particular to a high-strength tin-plated raw plate suitable for producing three-piece can bodies, easy-open lids, twist-off lids, etc., and its manufacture method. Background technique [0002] Packaging steel generally refers to a type of steel used to produce various cans and lids for food, beverages, and chemicals. The general thickness is less than 0.5mm, and the surface of the steel plate is often electroplated with tin or chrome. Because of its superior sheet performance, it is often used in various cans (such as two-piece beverage cans, three-piece beverage cans, milk powder cans, three-piece food cans, aerosol cans, paint buckets, etc.) and various covers such as crown caps, screw caps, etc. Production of open end, easy open end, etc. Based on people's continuous requirements for e...
