Float Glass Keep The Surface Smooth And Tidy

Float glass production process is mainly completed in the tin tank, the completion of the necessary conditions for the tin tank must have protective gas (N2 and H2) through. Float glass is produced by adding molten tin in the tank and adding glass to the molten glass. As the density of the molten glass relative to the molten tin is small, the glass will float on the surface of the molten tin solution, Under the influence of the surface pressure, the glass liquid will be opened and flattened on the surface of the molten tin liquid, thereby forming a glass ribbon having a certain width and thickness, and the surface of the glass ribbon is smooth and neat, and this glass ribbon is And the mechanical polished glass comparable, and this glass belt in terms of mechanical properties or from the chemical stability and other aspects, are better than the mechanical polished glass.

But due to the tin oxide is extremely easy to oxidize, resulting in a series of tin defects. Tin oxidation is the main reason for the occurrence of tin permeation on the surface of the float glass. When the glass after tin infiltration is heated, the surface of the glass will form a color, and the surface of the glass will become uneven and opaque. Glass production rate and deep processing, so that the application of glass greatly reduced, which is China's glass products can not be one of the main reasons for the development of fine. At present, there are many researches on the influencing factors of tin permeation on the surface of float glass, but with the improvement and upgrading of modern production technology, the development of the surface of tin has also developed a new development.

The mixture of the kiln head silo is pushed into the melting furnace by two inclined blanket feeding machines. The furnace is melted with heavy oil as fuel. The batch is melted into glass liquid, then it is clarified and homogenized. After cooling, the molten steel flows into the tin tank forming. There is no safety gates and adjustment gates on the runner. And no plate width flow control Road.

Glass liquid in the tin liquid from the flat, start, and then by mechanical pull the edge of the ribs and edge control, the formation of the required glass, and then pull out the tin tank, after crossing the roller into the annealing furnace. In order to avoid tin oxide oxidation, tin tank space filled with nitrogen hydrogen protection gas.

Into the annealing furnace glass belt in the annealing kiln, in strict accordance with the development of the annealing temperature curve for annealing, so that the glass residual stress control within the required range. The glass belt of the annealing furnace enters the cold end immediately.

Glass belt in the cold end after cutting off, to speed up the separation, breaking edge, breaking the longitudinal points, through the ramp, and by the hair sweep, and then into the sub-line, manual package packing stacking finished by forklift Finished product library.

In the cold side of the unit, set aside the washing and drying, automatic detection of defects, powder and the film automatically pick up the location of the container stacking equipment. Production line with a temporary board, breaking edge, the board off the board three landing device. So that the type of non-qualified board does not enter the cutting area. So that the failure of the board does not enter the box into the stacking area.
