摘要
气泡微细化实验是对工业中钢水脱硫的水力学模拟,根据相似性原理建立水模型实验,通过研究水模型实验中运动气泡的几何特性和运动特性来分析实际工业生产中脱硫剂的使用效率。通过设计合适的光路来获得最佳效果的拍摄图像;利用不同的图像处理流程分别对运动气泡图片进行处理,获得运动气泡的几何特性和运动特性。利用处理出来的数据进行气泡微细化实验分析,并对不同搅拌条件下气泡微细化实验的图像进行处理,寻找出最佳的气泡微细化实验条件。应用结果表明,所得出的最佳实验条件可大幅度提高镁的精炼反应效率,使反应速度加快,脱硫效率显著增长。
The micro-bubbles experiment is used to simulate molten steel desulfurizating in industry. The efficiency of desulfurizer is analyzed by studying geometric and kinetic characteristics of moving bubbles in water model experiment based on simulation principle. The appropriate light path is designed to obtain the best picture. By means of different image processing flows, moving bubble pictures are handled to get geometric and kinetic characteristics. The micro-bubbles experiment is analyzed using the obtained data, and the images in micro-bubbles experiments under different stirring conditions are processed at the same time, in order to find out the best micro-bubbles experiment condition. The application result shows that the obtained best experimental condition can increase the refining reaction efficiency of Magnesium, speed up reaction, and extremely improve the desulfurizating efficiency.
