A kind of glass toughening method

Abstract

The invention discloses a glass tempering method. When processing glass of the same thickness, the time used for glass tempering blowing is related to the length of each furnace of glass. The specific steps are as follows: 1) After each furnace of glass is heated, the glass When the front end of the glass enters the cooling grille or before entering the cooling grille, the cooling grille starts tempering and blowing; 2) When the end of each furnace glass enters the cooling grille, the timing of tempering blowing starts; 3) The tempering blowing time reaches the set glass tempering time After the time or the necessary time for glass tempering, the cooling air grid will change from tempering blowing to cooling blowing; 4) The cooling air grill will blow to the set glass cooling time or set glass cooling temperature to complete the glass tempering cooling. The method associates the tempering blowing time with the length of each furnace of glass through the controller and the displacement sensor, and reasonably controls the starting point and end point of the tempering blowing, so that the tempering blowing time is just right, which not only ensures the tempering quality but also reduces energy consumption.

Description

technical field [0001] The invention relates to a glass tempering method, in particular to a glass tempering method capable of precisely controlling the tempering blowing time according to the length of the glass through calculation, which not only ensures the quality of the tempered glass but also realizes the purpose of energy saving. Background technique [0002] The formation process of tempered glass is formed by heating the glass to a certain temperature and then cooling it down to a certain temperature according to a certain cooling rate. Correspondingly, the energy consumption of the glass tempering furnace can be mainly composed of three parts: [0003] 1. The energy consumption required to heat the glass to a certain temperature; [0004] 2. The energy consumption required to cool the glass to a certain temperature; [0005] 3. Other auxiliary energy consumption required for equipment operation. [0006] For heating energy consumption, the current thermal insula...

In order to complete the tempering of the glass with the largest specifications, the usual practice in the industry is to start the tempering timing when the front end of each furnace of glass reaches the end of the cooling air grid. As a result, the tempering time set by the process is longer than the necessary time for glass tempering, resulting in unnecessary waste
