Problems solved by technology

The technological process of the glass tempering production line mainly includes glass loading, glass heating process, rapid cooling process, slow cooling process, and finished product tempering after work and unloading. With ordinary processing technology, the glass enters the heating furnace for heating. The temperature of the upper grate during heating is Between 706°C and 712°C, the heating power of the upper grate is 95%, the temperature of the lower grate is controlled between 716°C and 721°C, the heating power of the lower grate is 81%, and the heating time is 163 seconds to 168 seconds. The furnace time is 10 seconds to 15 seconds. The heated glass enters the rapid cooling process. During the rapid cooling process, the enhanced air pressure is 457mmAg, the power is 96%, the distance between the upper air exhaust and the glass is kept at 23mm to 23mm, and the lower air exhaust and the glass Keep the distance between 29mm and 32mm, and then enter the slow cooling process. During the slow cooling, the wind pressure is 280mmAg, the power is 87%, the cooling time is within 100 seconds to 120 seconds, and the furnace speed of the glass is 600mm / second. This ordinary processing The 3.2mm tempered glass produced by the process is smashed in the middle, and the fragments within 50×50mm are less than 30 pieces, which does not meet the national standard

Abstract

The invention provides a tempering processing method for 4.0mm of steel glass. The 4.0mm steel glass processed according to the processing technological parameters has fragments more than or equal to 30 pieces within an area of 50mm multiplying 50mm and the bending degree smaller than 3 thousandth which meet the national standards. Glass enters a heating furnace for heating from a feeding bench, is quickly cooled in a quick cooling furnace after heated, then enters a secondary cooling furnace for cooling, and is transported out from a discharging bench after cooled. The invention is characterized in that the heating time of the glass in the heating furnace is 148 seconds to 160 seconds, and the awaiting time in the furnace is 10 seconds; in heating, the upper grate temperature is 695 DEC C to 705 DEC C, the heating power is 93 percent, the lower grate temperature is 690 DEC C to 695 DEC C, the heating power is 80 percent, and the glass discharging speed is 650mm per second; when the glass is quickly cooled in the quick cooling furnace, the strengthening wind pressure is 670mmAg to 700mmAg, the power is 100 percent, the upper wind exhausting distance is 16mm, the lower wind exhausting distance is 14mm, and the cooling time is 85 seconds to 110 seconds; and when the glass is in the secondary cooling furnace for slowly cooling treatment, the slowly cooling wind pressure is 300mmAg to 400mmAg, the upper wind exhausting distance is 16mm, and the lower wind exhausting distance is 14mm.
