The invention relates to a preparation method of non-oriented silicon steel 50SBW600 for high-voltage motors, comprising: S1, transporting a ladle containing refined molten steel to a turntable, and after the turntable is turned to a casting position, pouring the molten steel into a tundish; S2, The tundish distributes the molten steel to several crystallizers through the nozzle, and the crystallizer is provided with an immersion nozzle, S3, the molten steel generates a crystal nucleus in the crystallizer, and the crystallizer puts the molten steel with the crystal nucleus into the channel S4, a second electromagnetic stirrer is arranged on the channel, and the second electromagnetic stirrer carries out electromagnetic stirring to the molten steel in the channel, and the molten steel is gradually converted into a billet in the channel; S5, the billet pulled out by the straightening roller is pulled out of the channel and correct the shape of the steel billet; S6, cut the steel billet by the cutting device. The invention fully guarantees the quantity of equiaxed crystals in the steel billet during the continuous casting process and guarantees the surface defect quality of the product by arranging double electromagnetic stirring devices in the preparation process of the non-oriented silicon steel 50SBW600.
Description
technical field [0001] The invention relates to the technical field of metal smelting, in particular to a preparation method of non-oriented silicon steel 50SBW600 for high-voltage motors. Background technique [0002] Non-oriented silicon steel 50SBW600 is a silicon-iron alloy with very low carbon content. The grains in the deformed and annealed steel sheet are randomly oriented and distributed. The existing thin slab continuous casting and rolling process for the production of medium and low grade non-oriented silicon steel 50SBW600 is basically mature, but for medium and high grade non-oriented silicon steel 50SBW600, the traditional thick slab process is used for production, because the thin slab continuous casting and rolling process It has the process characteristics of continuous casting, such as fast cooling speed and no electromagnetic stirring. The continuous casting billet has less equiaxed crystals, so the hot-rolled band structure is serious, and corrugated def...
