Semi-tempering method The process of this method is to move the dried glass sheet after glazing into a heating furnace and heat it to a certain temperature, and then move it into a cooling chamber for controlled cooling.
Heating annealing method is to put the dried glass sheet after glazing into a continuous roller heating kiln, and make glazed glass after preheating, heating, annealing and cooling in the kiln. The highest temperature in the kiln is 670~715℃, and then annealing and cooling are carried out according to a certain temperature system.
