The present invention relates to an apparatus and a method for manufacturing tempered glass using chemical strengthening. The present invention relates to an apparatus and a method for manufacturing tempered glass using chemical strengthening, The glass is cooled by the first and second cold cooling steps in the first and second cold portions and the glass portion is cleaned by fine bubbles in a state where the stability of the glass is ensured in the cleaning portion, It is possible to reduce the manufacturing time as much as possible, to improve the yield, to improve the defect rate, and to make all the plate glasses such as the thin plate and the thick plate as the chemically tempered glass regardless of the size of the plate glass. |
