Example Embodiment
[0053] Examples A-H:
[0054] The steel for enamel of the present invention is manufactured according to the following steps, and the chemical element ratio of each embodiment is controlled as shown in Table 1 (see Table 2 for specific process parameters of each embodiment):
[0055] (1) Smelting and vacuum degassing: Iron oxide powder is added during the smelting process. The amount of iron oxide powder added is 0.40~2.50kg per ton of steel. After adding it, stir it thoroughly and the stirring time does not exceed 30 minutes, so that O ≥ 0.010 in the molten steel ~0.050%; After vacuum degassing, blow argon and stir to control H<2ppm in steel. When N≥(0.002~0.015wt%), blow nitrogen after vacuum degassing;
[0056] (2) Continuous casting;
[0057] (3) Hot rolling the cast slab: controlling the heating temperature of hot rolling to 950~1200℃, rolling in two stages, the first stage is rolled in the austenite zone, the temperature is 900~1100℃, the second stage is in the iron In the elem...
