Float Glass Bright And Bright, Colorless

- Aug 29, 2017 -

The process of float production is done in the tin bath into the protective gas. The molten glass flows continuously from the kiln and floats on the surface of the tin liquid with relatively large density. Under the action of gravity and surface tension, the molten glass is spread on the tin liquid surface and flattened to form the upper and lower surfaces, harden and cool After being cited as a transition roll table. Roller table roller rotation, the glass out of the tin into the annealing furnace into the furnace, the annealing, cutting, to get flat glass products.

Float glass is China's late 70s of last century, the first by the introduction of the British royal float glass glass production line. It is in the tin tank, the glass floating on the surface of tin liquid out. Therefore, this glass is first flat and good, no water ripples. For the mirror, car glass. Do not face, do not take shape, which is a major advantage.

Followed by the float glass selection of ore quartz sand, good raw materials. Produced by the glass pure, white, good transparency. Bright, colorless. No glass boil, bubbles and the like.

The third is the structure of close, heavy, feel smooth, the same thickness per square meter than the plate than the big, good cutting, easy to break.

Glass liquid in the tin liquid from the flat, start, and then by mechanical pull the edge of the edge and edge control, the formation of the required glass, and then pull out the tin tank, after the roller roll, 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 furnace, 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, defect detection, dusting and film in the automatic plate packing stacking equipment location. 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.

   The broken and crushed glass is conveyed from the rear of the production line to the front through the tape conveyor and sent to the tape conveyor for the belt conveyor on the outside of the annealing section. Normal production, the belt conveyor to turn the broken glass into the tape conveyor, the elevator into the kiln broken glass warehouse broken glass by the electric vibration feeder sent by the electronic scale weighing. And then spread to the batch material conveyor belt sent to the kiln warehouse. Excessive production of broken glass by the tape conveyor reverse into the broken glass yard. The small pieces of broken glass produced at the wafer and finished product are transported by hand to the broken glass yard. The broken glass of the yard is transported by the loader to the broken glass pits and broken into the outdoor crushed glass silo by the hoist. Use the buried warehouse under the vibration feeder into the tape conveyor sent to the kiln broken glass warehouse use.
