Abstract
The invention relates to an annular magnetic steel orientation technology, in particular to a thermal-treatment annular orientation technology of annular magnetic steel. Firstly, the annular magnetic steel is heated in a resistance furnace; then, the annular magnetic steel is sheathed on a high-speed rotation axis of an orientation magnetizer; a stepless speed regulating motor control system is used for controlling the revolving speed of the motor; orientated magnetization is carried out on the annular magnetic steel capable of preventing rotating in a magnetic field; after the orientated magnetization is carried out for 20 minutes, the magnetic field is closed, and the stepless speed regulating motor control system is closed; the orientation magnetizer is continuously surrounded in thermal storage material until temperature drops to below 300 DEG C; the thermal storage material out of the orientation magnetizer is removed, and the annular magnetic steel is taken down from the high-speed rotation axis; and thus the process of orientation is finished. By adopting the technology of the invention, common equipment can finish the thermal-treatment annular orientation of the annular magnetic steel with the specification of phi 80.97*phi 2.54*4.77mm. The orientation effect and the magnetic property of the product both conform to the technical requirement, while the requirements on energy conservation and environmental protection can be satisfied.
