The invention provides a processing method for rapidly tempering low-e glass. The processing method comprises the following steps of: 1, cutting the glass; 2, edging the glass; 3. downwards placing a low-e film in a heating furnace; 4, preheating and heating the glass; and 5, air cooling the glass. The processing method has the beneficial effects that the low-e film of the glass faces downwards, the problems of low temperature raising speed, non-uniformity in heating, damage to equipment and service life of the glass during heating are solved; electric energy is saved, the cost is further saved; the production efficiency is improved; and the quality of the glass is improved and the yield of the glass is increased.
