摘　　要：某浮法玻璃生产线在超白玻璃生产期间,出现大量气泡缺陷,在板带分布没有明显规律,厚度上位于玻璃板的中下部。经过检测分析气泡成分主要包含氮气(N2)、二氧化碳(CO2)、氩气(Ar),判断气泡缺陷来自于熔窑澄清部池底的耐火材料侵蚀。经过采取措施,降低熔窑澄清部池底耐火材料与玻璃液界面处的温度和玻璃液的流动性,达到了解决气泡缺陷的目的。在熔窑放完玻璃水后,检查熔窑澄清部池底耐火材料被侵蚀情况,印证了气泡缺陷来源的判断。In the production of ultra clear glass on a float glass line a big number of bubbles presented.The bubbles distributed irregularly cross the ribbon.On the thickness direction the bubbles located mostly in the center to bottom.Gas composition in the bubble was tested.By analyzing the gas amount of N2,CO2 and Ar the source of the bubbles was confirmed which was from the refractories of the refiner bottom.A lot of steps were taken to lower down the temperature and the flow on the boundary between refractories and glass melt and then the bubble defects disappeared.After the glass melt drain off and a check of the furnace significant corrosion to the refiner bottom refractories was found.This proved the judge of the origin of the bubbles from the refiner bottom refractories is right.
