In-roll EMS with high magnetic field of secondary cooling zone of slab is applied to maximize the electromagnetic thrust, so as to ensure optimum metallurgical effect.
1. High quality sintering coil is adopted, which is resistant to washing, water and high temperature;
2. High-quality dipping paint, covering paint, as well as process of vacuum dipping paint for three times are adopted to further improve insulation performance;
3. Use modern computer three-dimensional analysis software to optimally design the space distribution of the electromagnetic field, so that the magnetic field distribution of the EMS will be more reasonable, and the generated magnetic field force will be more effective;
4. High-quality oriented silicon steel is adopted as the iron core lamination, which can increase the magnetic field strength inside the EMS, improve the magnetic field saturation of the cylindrical iron core of the in-roll EMS, and reduce the comsuption of the EMS itself. The sleeve of in-roll EMS adopts high Ni-Cr heat-resistant and wear-resistant stainless steel, which can enhance the magnetism permeability and the service life.
