The effect of the composition of the atmosphere of the tin melt tank on the microhardness of the float-glass surface

The effect of the content of water vapor and oxygen in the atmosphere of a tin molten bath on the microhardness of the surface layers of float glass from various enterprises in Russia and Ukraine has been studied. It is shown that an increase in the water vapor content does not lead to a significant decrease in the surface microhardness. At the same time, an increase in the concentration of molecular oxygen causes a decrease in the surface resistance to the action of abrasive particles. Il. 1, bibliography: 5 titles.
