Tin Defects in Float Glass

The function of the float glass tin bath is to melt the molten glass in the furnace under a certain temperature system, and through the external force of the main drive and the edge pulling machine, form a certain width and thickness of glass. After forming and cooling, it is sent to the annealing furnace through a transition roller table.
The tin bath in the float process uses metal tin liquid as the float medium, and a mixture of nitrogen and hydrogen gas as the protective gas. In the relatively enclosed environment of the tin bath, many complex chemical reactions occur, and some of the products from these reactions will bring many glass defects, affecting product quality.
The environmental and structural characteristics of the float glass tin bath determine that tin defects are inevitable and can only be effectively controlled, not eliminated, in actual production.
