Embodiment Construction

[0032]Refer to Table 1 for Examples 1-10, and add a pair of ratios, and the balance is iron and other unavoidable impurities. Carry out smelting and processing according to the process of the technical plan. In Example 1-5, the hot rolling heating temperature is 1150°C, the finishing rolling temperature is 880°C, the coiling temperature is 700°C, the cold rolling reduction rate is 66%, and the bell annealing temperature is 700°C. Bell annealing nitrogen content 6%. Example 6-10 The hot rolling heating temperature is 1200°C, the finish rolling temperature is 900°C, the coiling temperature is 730°C, the cold rolling reduction is 67.5%, the bell annealing temperature is 700°C, and the bell annealing nitrogen content is 8%. Its finished product properties are shown in Table 1. It can be seen from Table 1 that the elongation rate of the finished product performance is 43-53% (gauge length 80mm), the average is 47%, and the three-way r m The value is 1.82-2.33, with an average of ...

Description

technical field [0001] The invention relates to a cold-rolled enamelled steel and a manufacturing method thereof, in particular to an ultra-low carbon cold-rolled enamelled steel with excellent scaling resistance and ultra-deep drawability and a manufacturing method thereof. Background technique [0002] Ultra-low carbon enamel steel is a new generation of enamel steel developed in the 1980s. It can meet the needs of the production of enamel products with complex shapes, difficult stamping and high enamel quality. [0003] The world's main manufacturers of ultra-deep enamelled steel sheets include Japan's Nippon Steel, Nippon Steel, and Germany's Thyssen, and there are no related patents in China. In the manufacturing process of enamelled steel, foreign manufacturers adopt ultra-low carbon steel based on deoxidized aluminum. By controlling the chemical composition range and processing parameters in the steel, the steel plate has excellent scale r...
