Tempering furnaces are non-standard equipment. How to choose and purchase tempering furnaces is also a matter of skill. At the same time, in the process of selecting and purchasing glass tempering equipment, the plant area, production environment and power situation of glass deep processing enterprises should be considered.

According to the industry of using tempered glass, it can be divided into building and private fiberglass tempering furnace, automobile fiberglass tempering furnace, household appliances fiberglass tempering furnace and solar energy fiberglass tempering furnace; according to the structure and functional characteristics of the equipment, it can be divided into combined tempering furnace, continuous tempering furnace, flat glass tempering furnace, bending fiberglass tempering furnace, bidirectional tempering equipment, unequal arc/variable curvature tempering furnace, etc. According to the heating source, it can be divided into electric heating type glass tempering furnace and gas heating type glass tempering furnace, in which electric heating type glass tempering furnace can be divided into forced convection tempering furnace and radiation tempering furnace according to the heating characteristics of equipment; forced convection tempering furnace can meet the tempering process of high quality glass, with the global market for the safety and energy saving requirements of tempered glass. As a result, convective steelmaking furnace has gradually replaced radiant steelmaking furnace as a trend.  Taking forced convection leveling steelmaking equipment as an example, convection steelmaking equipment usually consists of upper stage, heating furnace, steelmaking section, lower stage, fan air circuit and electrical control system. In the heating section, the heat preservation material, anchoring technology, heating method and the quality of ceramic roller have a great influence on the quality of goods; in the tempering section, the planning of wind grate, the size of wind blower and the operation of wind pressure have a decisive role on the tempering effect of glass; some other machines also need skills and quality assurance. Intelligence and stability of electrical control system are also essential factors affecting the operation of steelmaking equipment, which should be considered when purchasing steelmaking equipment.

Crystal Diamond Glass Machinery has summarized several points for purchasing tempering furnaces based on its many years'experience.

1. The glass produced by the tempering furnace should be smooth and of good particle size. (Product quality)

2. Manufacturers must be professional, have their own patented technology, have their own team, and the factory area, do not be deceived by some bag companies. (Professional strength)

3. The steelmaking furnace must be energy-saving, saving more than one kilowatt hour per square meter, and earning an extra dollar. (Save money)

4. The steelmaking furnace should be intelligent and easy to operate. Don't make any meaningless increases in labor costs. (Cost reduction)
