文章介绍了西门子罗宾康系列中压变频器在转炉一次除尘风机中的应用。转炉炼钢具有显著的的周期性和连续性特点,生产一炉钢需要30min-45min,其中一半以上为非吹炼时间,此时风机不需要高速运行,如将其切换至低速状态,可节省大量能源,减少设备损耗,提高设备利用率。 This article introduces the application of Siemens Robin Kang series medium voltage frequency converter in the primary dedusting fan of the converter. Converter steelmaking has the characteristic of periodicity and continuity. It takes 30min-45min to produce a steel furnace, of which more than half is non-blowing time. At this time, the fan does not need high-speed operation, such as switching it to low speed, saving Large amount of energy, reduce equipment loss, improve equipment utilization.
