The effect of mechanical agitation on convective blending of the glass mass

Experimental data on the features of the flow of molten glass at the beginning of the cold part of the furnace behind the obstacle and in front of the working zone when using mixers on industrial glass furnaces are presented. It has been established that to eliminate coarse streaks and layers, it is necessary to increase the gradient of the flow rates of the molten glass by 2 orders of magnitude in comparison with natural homogenization. This is achieved most simply and effectively by mechanical stirring of the molten glass. Tab. 1, ill. 3, bibliography: 11 titles.
