Abstract

The invention discloses a process for production of high-strength pressure-resistant toughened glass. The process comprises the following steps: step 1, pretreating heat-resistant glass; step 2, delivering the pretreated heat-resistant glass to a preheating section of a toughening furnace. and preheating for 1-2h at the preheating temperature of 900-1000 DEG C; step 3, raising the temperature to 1200-1300 DEG C at the rate of 20-30 DEG C/min, and heating for 30 min; and step 4, delivering the heat-resistant glass heated in the step 3 to a quenching cooling section of the toughening furnace, and performing cooling molding to obtain a finished product of the heat-resistant toughened glass. The process for production of the high-strength pressure-resistant toughened glass can quickly heat theheat-resistant glass, can perform heat circulation through a high-temperature convection fan so as to uniformly heat the heat-resistant glass, can reduce heat energy consumption, is favorable for energy saving and emission reduction, can effectively enhance the strength, the cold and heat resistance and the impact resistance of the heat-resistant glass, and can effectively remove heat stress andresidual stress in the heat-resistant glass.

Description

technical field [0001] The invention relates to the technical field of high-strength compression-resistant tempered glass, in particular to a process for producing high-strength compression-resistant tempered glass. Background technique [0002] With the development of society, people have higher and higher requirements for glass, such as people's requirements for glass strength and glass hardness, and high-strength pressure-resistant glass means that the overall structure of the glass remains intact under a certain pressure impact. , non-breaking special glass, and tempering is a process of further strengthening the strength of glass. [0003] However, it is inconvenient for people to produce high-strength compressive tempered glass, because it is not convenient to ensure the uniform heating of the glass, which is not conducive to ensuring the quality of the glass, and is not conducive to the rational use of heat energy, which is not conducive to saving energy.
