What Is A Tempering Furnace

Have you ever seen a piece of glass shatter? You have probably dropped a glass or seen a window break atsome point in your life. What happens? That glass shatters into countless pieces that are sharp and jagged.What about really big windows? Any large windows these days when broken will, instead of completelyshattering will break into granular chunks that are much less likely to hurt someone. That can happenbecause the glass has been treated with a process that involves heat and chemicals that makes it tougherthan normal glass. This process happens in something called a tempering furnace. This tempered glass hasmany, many applications. It is used in vehicle windows, tables, shower doors, bulletproof glass, masks forscuba diving, and many types of cookware.

Tempered glass is made from annealed glass, or glass that has been slowly cooled through a process calledannealing. This piece of glass is then placed on table with rollers that push it through a furnace that heats itto a high temperature. The glass is then cooled rapidly with drafts of air. This tempers the glass and makes itextra tough. Another process involves a chemical solution of molten potassium nitrate. This process actuallymakes the glass tougher than tempering and can be used to toughen oddly shaped pieces of glass, not justsheets of glass.

If you are a company that makes toughened safety glass, you are going to need a tempering furnace toproduce this glass. Larger glazers will be able to afford furnaces in house and will usually rent time on thesefurnaces to smaller or medium sized glazers. However, there are newer more efficient methods of producingthese furnaces that can make it affordable for smaller glazers to afford their own production furnace.

Modern furnaces use a ?bath enclosure? technology that makes producing safety glass much more efficient.Precise computer controls allow exact measurements and electric motors provide the correct amount ofoscillation during production. The quenching section is also computer controlled and can be programmed tofurther automate the production process.

These kinds of furnaces are great whether you generate a large volume of production or you only intend tooperate on a smaller scale. With so many applications of safety glass, the industry has plenty of demandavailable. There are also many variations of furnaces available. When thinking about which furnace topurchase, consider what products you are aiming to produce. The size of these products will probably be themost important factor to look at when buying a furnace. There are many different sizes of furnaces availablewith different widths and lengths depending on what size you need. How much space do you have in yourproduction facility? Do you need the biggest size or do you just need the minimum to create your glass?

The tempered glass industry has so many applications that a small to medium sized glazer can now mostlikely afford to purchase his very own dedicated to produce the product. With this brand new temperedfurnace, you?ll be able to avoid the costs associated with contracting out to another shop to get your glasstempered. With a furnace in-house, if mistakes are made, corrections can be made much more quickly. Theinvestment made can be quickly recouped by getting the right kind of tempered furnace.
