Embodiment Construction
[0019] The present invention will be further explained below in conjunction with the drawings.
[0020] The technical problems involved in the present invention are solved by the following technical solutions: A production method of high silicon electrical steel, the specific production process is:
[0021] (1) Smelting two-component molten steel, one has a silicon content of 2.0% to 3.5%, and the other has a silicon content of 4.5% to 7.0%, and the other components in the steel are the same as the target composition.
[0022] (2) Continuous casting is used to cast molten steel into billets with a superheat of 10-30°C; a drainage device 1 is provided in the continuous casting mold 5, and the drainage device 1 is open at one end and downward, and the interior of the drainage device 1 is empty In cavity 4, the drainage device 1 is suspended in the molten steel, a gap of 10-40 mm is formed between the outer wall of the drainage device 1 and the mold 5, and the lower opening of the inner...
