Latest Patents

Guoping Cheng holds a patent for a continuous annealing method for low coercive force cold-rolled electromagnetic pure iron plate and strip. This method involves precise control of parameters during the continuous annealing process. The heating stage operates at temperatures between 750-850°C, followed by a soaking stage with a soaking time of 100-150 seconds. The slow-cooling stage has an outlet temperature of 575-675°C, with a cooling speed of 2.5-10°C/s. The fast-cooling stage operates at an outlet temperature of 380-420°C, with a cooling speed of 15-25°C/s. Finally, the overaging stage is maintained at 270-310°C. The annealing medium used is a non-oxidizing atmosphere composed of hydrogen and nitrogen. After the annealing process, the cold-rolled electromagnetic pure iron plate and strip is leveled and pressed, ensuring that the leveling elongation rate is controlled within the range of 0.2±0.1%. This innovative process simplifies production while achieving low coercive force and good formability without the need for further magnetic annealing.
