The molten glass, which by now has dropped to 1100 degrees C, forms a continuous ribbon that floats on the molten tin. The desired width and thickness is obtained through an operator controlled program which sets the speed of the annealing lehr and knurl machines. The ribbon thickness can range from 2 to 12 mm. As the continuous ribbon moves through the float furnace its temperature is gradually reduced allowing the glass to become flat and parallel.
The float furnace consists of support steel, upper and lower welded steel casings, a refractory liner, tin, electric heating elements, an oxygen eliminating atmosphere system,temperature sensors, and a computerized process control system. Gold Plus float furnace is specifically designed to respond to heat flow balance, desired ribbon width of 3660mm, glass thickness of 2 -12mm, glass color of clear and green and the gross daily production tonnage of 460 tonnes per day.
