[0024] The preparation method of wind tempered glass according to the present invention comprises the following steps: first place the glass on the loading table, enter the heating chamber through the conveying roller table, send it out of the heating chamber after preheating, temper and cool, and then unload the glass The process is taken out and formed into wind-tempered glass; the above-mentioned heating chamber cavity is equipped with at least 4 heating sections, and a maximum of 6 heating sections can be set up; a sealed door with a control device is installed at the exit of each heating section; the total heating in the heating chamber The temperature is 290°C-720°C, which are respectively arranged in each heating section from front to back; the temperature between the previous heating section and the next heating section increases in a trapezoidal manner, and the temperature difference is 100-150°C; the heating of each section The time is 100-300 seconds; the specific se...
Embodiment 1
[0029] Select a piece of ordinary flat glass with a specification of 1000×1000×10mm, check the appearance quality for defects such as stones, bubbles, scratches, etc., grind the surrounding area on a linear edging machine, wash and dry it for later use.
[0030] The air tempering equipment is equipped with a loading table, a heating chamber, a cooling section and an unloading section. The roller table runs through the loading table, heating chamber, cooling process and unloading process; the above-mentioned ordinary flat glass is placed on the roller on the loading table. On the road, start the motor, the roller table rotates, and the glass is sent from room temperature to the heating chamber for heating. The heating chamber is divided into 4 sections, the 1st, 2nd, and 3rd sections are respectively set for electric furnace wire radiation heating, that is, electric furnace wires are respectively installed on the upper and lower sides of the heating section; Airtight boxes are ...
Embodiment 2
[0037] The specifications of the selected glass, the tempering equipment used, the heating time for each section of the heated glass and the speed of the single forward movement of the glass during the operation are the same as in Example 1, and will not be repeated here.
[0038] The difference is that the heating chamber is divided into 4 sections, and the first and third sections are respectively set for electric furnace wire radiation heating, that is, electric furnace wires are respectively installed on the upper and lower sides of the heating section; the second and fourth sections are heated by convective air circulation, That is, airtight boxes are installed on the upper and lower sides of the furnace body, heating devices are installed in the box, air inlets and outlets are arranged at the upper and lower ends, the air inlet is connected to the exhaust end of the fan through pipes, and the air outlet is a spray hole plate, and the ejected gas returns to the air. To the...
