基于面装式永磁同步电机的转炉炼钢氧枪位置控制

摘要

Oxygen blowing is an important process in converter steel smelting. Tradition-al oxygen lance drive device adopts DC speed adjusting control system, but with rapid devel-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-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.%在转炉炼钢过程中的一个重要工艺是吹氧，传统的氧枪传动装置采用直流调速控制系统，随着电力电子技术的发展，交流传动系统以其优越的控制性能逐渐取代了直流调速系统。主要研究了基于面装式永磁同步电机的转炉炼钢氧枪位置控制系统。在整个控制系统中，通过对面装式永磁同步电机的控制，实现了氧枪位置的精确控制，提高了系统效率。
