Transformation of Master-slave Control for Converter Tilting Based on AB755 Series Frequency Converters
The tilting device of the converter is a crucial equipment in the smelting process.During the smelting process,the tilting system of the furnace body needs to rotate±360°.During the rotation process,the center of gravity of the liquid steel changes with the inclination angle of the converter,and the furnace body has potential energy load characteristics,so higher requirements are placed on the transmission system.This article is based on the successful application of AB755 series frequency converters in the tilting system of a 120 t converter.It elaborates in detail on the transmission master-slave control logic,brake control logic,three in one backup redundant control scheme,and key and difficult debugging points.
