Ltd., Maanshan, Anhui 243003, China) [Abstract] Oxygen blowing is an important process in converter steel smelting. Tradition原 al oxygen lance drive device adopts DC speed adjusting control system, but with rapid devel原 opment of electronic technology for electricity power system, AC lance drive system with its excellent control performance has gradually replaced DC speed adjusting system. The oxygen lance position control system for converter based on surface-mounted permanent magnet syn原 chronous motor is studied. In the entire control system, precision control of the lance position is achieved by control of the surface-mounted permanent magnet synchronous motor, which improves the efficiency of the system.
