Abstract

The invention discloses a manufacturing technology of semi-tempered glass. The manufacturing technology comprises the first step of preheating treatment of glass, wherein the glass to be treated is placed in a preheating furnace, and the glass which is subjected to preheating treatment is obtained through three stages of warming and heating; the second step of semi-tempered treatment, wherein the glass which is subjected to preheating treatment is sent into a toughening furnace, then warming is conducted to achieve semi-tempered treatment to obtain the glass which is subjected to semi-tempered treatment; the third step of rapid cooling treatment, wherein the glass which is subjected to semi-tempered treatment is sent into a quenching area, and rapid cooling is conducted at the wind pressure of 50-150 Pa for 3-8 min; the fourth step of annealing treatment, wherein the glass which is subjected to rapid cooling treatment is transferred to an annealing furnace with the temperature being 350-380 DEG C, and the temperature is lowered to 80-90 DEG C for 40-50 min to conduct annealing treatment, and then conducting cooling at the room temperature is conducted to obtain the semi-tempered glass. The manufacturing technology of the semi-tempered glass is flexible in operation, the manufactured semi-tempered glass is uniform in mass distribution, and flat and smooth, the probability of spontaneous explosion in a cooling process is low, the surface stress is strong, and the problems of edge breakage and warping cannot occur.

Description

technical field [0001] The invention relates to the technical field of tempered glass production, in particular to a production process of semi-tempered glass. Background technique [0002] Semi-tempered glass, also known as heat-strengthened glass, is a variety between ordinary flat glass and tempered glass. It has some advantages of tempered glass, such as higher strength than ordinary float glass, while avoiding the flatness of tempered glass. Poor, easy to self-explode, once destroyed, the whole body will be crushed and so on. When semi-tempered glass is damaged, it will crack radially along the crack source, generally without tangential crack propagation, and it can still keep the whole body from collapsing. [0003] In the semi-tempered glass production process, the heating and cooling of glass is the focus of tempering. According to uniform requirements, the heated glass must be cooled as quickly and evenly as possible with an optimum cooling rate. The cooling proc...
