Description

The lower air grid of tempered glass cooling

Technical field

Glass tempering air grid is the utility model is related to, more particularly, to a kind of lower air grid of tempered glass cooling.

Background technology

Tempered glass refers to after re-treating process, and the glass of compressive stress layer is formed in glass surface.Tempered glass Using relatively extensively, it is multiple building, auto industry, transport, electronics, chemical industry, medical treatment, printing etc. have been generalized to from earliest aviation field Field.The method of tempered glass is a variety of, is generally divided into two major class of physical toughened method and chemical tempering process.Physical toughened technique is by quenching Cold medium divides, and can be divided into the cold tempering method of wind-cooling reinforcing method, liquid, particulate tempering method and spraying tempering method etc..Wind-cooling reinforcing method Advantage is that cost is relatively low, and yield is larger, has higher mechanical strength, resistance to sudden heating（Maximum safe working temperature is reachable 287.78℃）Higher Heat-Resistant Gradient（It is amenable to 204.44 DEG C）, and Air quench hardening glass be in addition to it can strengthen mechanical strength, Fractionlet can be formed when broken, the injury to human body can be mitigated.But the thickness and shape to glass have certain requirement（State The glass minimum thickness of equipment institute tempering is produced generally in 3mm or so）.

The tempered glass of air cooling method production at present（Including flat tempered glass and curved tempered glass）Capital equipment be annealing furnace. When tempered glass is processed mainly in two steps：Glass is heated near softening point in bringing-up section first；Then will heat Glass, be transferred to cooling section rapidly by roller-way and carry out quenching and cooling, cooling section and be made of multigroup air grid, wind turbine is according to work Skill requirement, send the air for setting wind pressure into air collecting box room, is then sent into air grid collection wind of the equalization setting in both sides by air passage Intracavitary, the glass passed through between being faced therefrom from glass two at the same time by the blowhole opened up in air grid blow-down panel carry out quenching（Quench Cool time is generally at more than ten seconds）, then or decompression continues to cool down or is transported to next cooling section and continues cool to room temperature（30~40 ℃）, glass tempering process terminates.Qualified tempered glass surface stress >=90MPa, granularity >=40.Quenching and cooling make Wind pressure is different（Quenching requires wind pressure high）, quenching and cooling can be completed in same section of air grid（Common reciprocal tempering Stove uses which）, or in different air grid section completions（Low wind pressure section is gone to after high wind pressure quenching to continue to cool down, it is usually more A heating chamber and continuous annealing furnace use which）.

The air grid of quenching section is formed by multigroup upper air grid and multigroup lower air grid in existing annealing furnace, and upper air grid with it is upper Layer rollgang（Or roller）It is staggered, lower air grid and lower floor's roller-way（Or roller）It is staggered, easy to convey glass.But It is, for some specific glass, such as V-arrangement glass（The V-shaped glass formed by two planar portions by curved portion linking）, due to Its shape is special so that the installation space of lower air grid and lower floor's roller-way is extremely limited, while adds the tune of lower air grid outlet air surface Difficulty is saved, the yield rate of specific glass only has 50%.In order to solve the above technical problems, some enterprises by square steel tube by roller-way（Or Roller）On lower air grid, installation space has been saved, has added the adjusting space of air grid.But above-mentioned technical proposal is deposited In problems with：Firstly, since square steel tube straightness is poor, itself and roller-way（Or roller）Fitness it is low, after tempering glass into Product rate is still very low, and only 55% or so；Secondly, square steel tube wall is relatively thin, it is necessary to is installed using welding procedure, upper air grid It is cumbersome with roller-way installation process complexity, reduce installation effectiveness；Furthermore square steel tube weight is larger, lower air grid institute is considerably increased The gravity born, under the influence of air grid service life.
