摘要
连铸中间包的钢水的液位测量环境恶劣和钢水上层覆盖保护渣层而导致钢水液位测量困难、测量准确度不高.针对此现状,本文提出了一种基于温场信息,利用计算机视觉测量实现的钢水液位测量方法.此方法通过对中间包内的空气层、保护渣、钢水层温场分析和获取,确定空气层-保护渣层和保护渣层-钢水层的温度梯度分界面位置,从而得到中间包内钢水液位.测量方法应用到现场,统计得到测量平均绝对误差为3.2mm,最大误差为5.2mm,最小达到0.3mm,本文液位测量方法准确可靠,具有良好的应用前景.
Steel level measurement in continuous casting tundish has been trapped in a problem： atrocious measuring circumstance caused by high-temperature of molten steel and the flux slag on upper layer make it difficult to measure molten steel level accurately.According to this fact,a new method based on temperature field information is put forward to molten steel level measurement.By means of analyzing temperature distribution of different layers in continuous casting tundish, including the air layer, the slag layer and the molten steel layer, air-slag layer and slag-steel layer interfaces location are located, and the molten steel level is measured accurately finally. Application of this method in field shows measuring error is 3.2mm, the maximal error is 5.2mm, and the minimal error comes to 0.3mm. It indicating this method is authentic and it has a favorable application prospects.
