In one embodiment, the distance between adjacent air grid lower roller tables 14 is 100mm-120 mm. Because the positions of the air grid upper roller ways 13 correspond to the positions of the air grid lower roller ways 14 one by one, the distance between the adjacent air grid upper roller ways 13 is also 100mm-120 mm.
In one embodiment, the hot air pipes include an upper hot air pipe 15 positioned at an upper portion for blowing hot air to the upper edge of the glass 2 and a lower hot air pipe 16 positioned at a lower portion for blowing hot air to the lower edge of the glass 2. Through blowing hot-blast simultaneously to the upper edge and the lower limb of glass 2, can make the both sides edge cooling rate homoenergetic of glass 2 reduce, guarantee better cooling homogeneity.
In one embodiment, as shown in fig. 2 and 3, the upper hot air pipe 15 is disposed to be inclined from top to bottom, and the lower hot air pipe 16 is disposed to be inclined from bottom to top. Because the edge of the surface of the glass 2 is blown with hot air, the air outlet of the hot air pipe needs to be opposite to the edge of the surface of the glass 2, and the embodiment adopts an inclined arrangement mode, so that the air blowing effect can be improved, and the space can be saved.
In an embodiment, the upper hot air pipe 15 and the lower hot air pipe 16 are arranged in plurality at equal intervals, and the upper hot air pipe 15 and the lower hot air pipe 16 are equal in number and are arranged opposite to each other. That is, the number of the upper hot air pipes 15 is the same as that of the lower hot air pipes 16, and the positions of the upper hot air pipes 15 correspond to those of the lower hot air pipes 16 one by one, so that the cooling rate can be reduced for the entire edge of the glass 2.
In one embodiment, the distance between adjacent upper hot air pipes 15 is 100mm-120 mm. Because the positions of the upper hot air pipes 15 correspond to the positions of the lower hot air pipes 16 one by one, the distance between the adjacent lower hot air pipes 16 is also 100mm-120 mm.
In an embodiment, the diameters of the upper hot air pipe 15 and the lower hot air pipe 16 are both 3mm-8mm, and the upper hot air pipe 15 and the lower hot air pipe 16 may be the same or different, but the same diameter may be adopted in specific applications, so as to ensure that the cooling rate reduction amplitude is consistent.
In one embodiment, the upper hot air pipe 15 is arranged to intersect with the air grid upper roller table 13. In a specific application, the upper hot air pipe 15, the air grid upper roller way 13, the upper hot air pipe 15 and the air grid upper roller way 13 can be arranged in a crossed mode. In specific application, the number of the upper hot air pipes 15 can be 1 less than that of the upper grid roller ways 13, and the number of the lower hot air pipes 16 is 1 less than that of the lower grid roller ways 14.
In one embodiment, the asbestos sleeve is made of aramid fiber and wraps the whole roller way. The height of the air grid upper roller way 13 can be adjusted according to the thickness of different glass 2.
The processing steps of the toughened glass are as follows:
the method comprises the following steps: heating: putting the substrate glass after cutting and edging into a toughening furnace for uniform heating, and after the glass 2 is heated, putting the obtained glass 2 into an air grid section for cooling;
step two: and (3) cooling: after the glass 2 enters the air grid, cooling is carried out at a certain speed. During cooling, the glass swings on the air grid lower roller way 14, the air grid upper roller way 13 is in contact with the upper surface of the glass 2, and meanwhile, the hot air pipe is opened to blow hot air to the edge of the glass 2, so that a semi-tempered glass finished product is obtained.
Further, in the step one, the furnace temperature of the toughening furnace is 680-700 ℃, and the heating rate is 40-60 s/mm. The temperature of the glass is 600-620 ℃ when the heating is finished. After the glass 2 is heated, the temperature difference of each point of the same glass 2 is not more than 10 ℃.
Further, the cooling rate of the glass 2 in the second step is 2 ℃/s to 3 ℃/s. When the glass 2 is cooled by the air grid, the upper roller table 13 of the air grid just contacts the upper surface of the glass 2 and does not generate any pressure on the glass 2.
Furthermore, the opening time of the hot air pipe is 15-25% of the cooling time of the glass 2 entering the air grid, and the temperature of hot air blown out by the hot air pipe is 400-600 ℃. The cooling time of the glass 2 entering the air grid is 15s/mm-25 s/mm.
The utility model discloses use the asbestos cover to replace the asbestos rope, reduce glass 2 because the heat that the roll table scatters and disappears, glass 2 uses hot-blast 2 edge cooling fast problems of reduction glass that the steam pipe blew off simultaneously when the cooling. Thereby ensuring the cooling uniformity of the whole glass 2 and reducing the problem of stress spots of the semi-tempered glass.
