摘要
结晶器钢水液位检测和控制是连铸机生产控制的核心环节之一,稳定的结晶器液位对提高铸坯内部和表面质量、避免保护渣及其他非金属夹杂物卷入、减少漏钢或溢钢等生产事故具有重要意义。尤其是高拉速、高通钢量的ESP薄板坯连铸机,其对液位检测和控制的精度要求更高。以往在ESP连铸机使用的结晶器液位传感器均为NKK系统,其具有成熟的应用经验。针对VUHZ液位检测系统首次在ESP连铸机上的应用,通过优化系统控制参数、信号补偿、冷却水系统等解决了影响VUHZ传感器液位检测的问题。实践表明,在高拉速条件下,VUHZ系统液位控制精度及液位波动能够满足现场工艺生产要求。
The detection and control of molten steel level in mold is one of the core links of continuous casting machine production control.Stable liquid level in mold is of great significance to improve the internal and surface quality of casting slab,avoid the involvement of slag and other non-metallic inclusions,and reduce production accidents such as breakout or steel overflow.Especially for ESP thin slab caster with high cast speed and high throughput,it requires higher accuracy of liquid level detection and control.All mold level sensors used in ESP continuous casting machines are NKK systems,which have mature application experience.Aiming at the first application of VUHZ level detection system in ESP caster,the problems affecting VUHZ level detection were solved by optimizing system control parameters,signal compensation and cooling water system.The practice shows that the level control accuracy and level fluctuation of VUHZ system can meet the requirements of field process production under the condition of high pulling speed.
