Abstract
An apparatus and a method for continuously manufacturing tempered glass are provided. The tempered glass is continuously manufactured by transferring the raw glass in one direction, spraying a boiled potassium nitrate solution to the raw glass to reinforce the raw glass, and recovering and reusing the potassium nitrate solution from the raw glass. This invention can reduce the time to manufacture tempered glass since you can manufacture tempered glass consecutively, and the cost of purchasing potassium nitrate solutions can be reduced, which has an economic advantage. Since the raw glass is preheated, strengthened and annealed by divided sections of preheating, strengthening and annealing section in one furnace, it is less likely that impurities will be attached to the raw glass due to low external exposure during each process movement, thus preventing deterioration of quality.
