The invention relates to the technical field of glass manufacturing, and particularly relates to a method for manufacturing high-strength environmental protection fireproof glass, the steps are as follows: 1. cold treatment of ordinary selected floating glass; 2. feeding cold-processed float glass into special tempering The furnace is heated; 3. The glass heated to the softening temperature is sent to the special air discharge at a speed of 300-500 mm per second; 4. When the glass enters the air discharge, the high-pressure air and the high-pressure fan are used, and the wind is discharged through the wind, the special wind The mouth immediately gives the glass surface a high-strength homogeneous cold air for cooling, and immediately carries out high-strength physical tempering, instantly achieving the strength stress required for the high-strength fire-proof glass, and solving the strength that cannot be achieved by the general tempering of the fireproof glass, so that the glass stress reaches 190~ 210MP. Through the above steps, the fireproof glass processing conditions are more convenient, faster and more stable, and the fireproof performance is more stable, reliable and environmentally friendly.
