High borosilicate glass tempering furnace: How should the price and purchase of a tempering furnace be considered?

Choose a well-known brand; its forced convection technology is an advanced technology. Large manufacturers have their own R&D teams, ensuring product quality and after-sales service. In addition, large manufacturers can customize and modify non-standard equipment according to the actual needs of customers to better meet production requirements. From design drawings to equipment debugging, to later services, you can save a lot of worry. So, high borosilicate glass tempering furnace: How should the price and purchase of a tempering furnace be considered?

High borosilicate glass tempering furnace: How should the price and purchase of a tempering furnace be considered?

1. Market positioning and function selection. First, consider your tempered glass market and the functional positioning of the tempering furnace. Currently, the main forced convection annealing furnaces on the market include: flat annealing furnace, curved annealing furnace, flat and curved two-way annealing furnace, curved two-way annealing furnace, and unequal arc annealing furnace. Different types of annealing furnaces have different uses and can be selected according to needs.

2. For high borosilicate glass tempering furnaces, such as large flat glass mainly used in construction, flat tempering is the main function to consider. For example, Shencheng's LD-AJ series forcedly uses jet forced convection heating technology for flat tempering, which can meet the tempering processing of high-quality flat glass for construction and furniture; types of tempered glass include: online and offline Low-E (E=0.02) glass, ultra-white glass, silk-screen glass, embossed glass, colored glass, white glass, etc. Of course, if you want a wider product coverage, you can choose a flat and curved two-way tempering furnace, which takes into account both flat and curved glass. However, the cost of this annealing furnace will be higher.

3. Selection of convection method, convection surface, and convection process. Currently, forced convection annealing furnaces are increasingly recognized by industry professionals. Compared with traditional radiation annealing furnaces, it has many advantages and is gradually favored by customers. These factors are very important for choosing a forced convection annealing furnace; it not only affects product performance but is also crucial for cost control. Currently, forced convection annealing furnaces are divided into two modes: upper convection and full convection. Full convection is more expensive, but the annealing furnace launched by Shencheng is an excellent representative of forced convection furnaces.

4. High-temperature convection curve control of high borosilicate glass tempering furnace. The control of the high-temperature convection curve reflects the temperature control ability of the furnace heating area. Unevenly heated glass is prone to unqualified tempering and furnace explosion. When purchasing, it should be noted that due to the horizontal placement of the convection fan, the temperature curve control on both sides of the furnace body may not be ideal. When choosing a forced convection annealing furnace, consider companies that do better in this aspect.

5. Selection of heating system (electric heating wire). Many annealing furnaces use ordinary radiation furnace electric heating wires; good manufacturers will use CrNi materials. The price of this material is more than ten times that of ordinary radiation furnace electric heating wires, but it has a long service life and good stability, and can basically achieve the purpose of not changing the electric heating wire for many years.

6. The smoothness and high-temperature resistance of the roller track directly affect the quality of the glass. General manufacturers use ordinary ceramic roller tracks, and the transmission accuracy cannot be guaranteed. In addition, the vibration of the transmission system has a great impact on the ceramic roller track, which can cause roller track deviation and wear due to asynchronous transmission.

7. The annealing section wind pressure auxiliary control system can reduce the dependence on the experience of operators, improve production efficiency, and reduce the defect rate caused by human factors. Good manufacturers use imported industrial electrical appliances for the main control part, and the temperature module control ensures the reliability of the system. The furnace body and box body material is nickel-chromium stainless steel. Generally, the grade of electrical products on the market is relatively low, and the internal materials are also uneven. It is also necessary to pay attention to factors such as site selection and supporting conditions.

8. Its heating furnace is higher than an ordinary radiation furnace. In addition, the external fan of the annealing furnace is relatively large, so this should be considered when choosing a workshop.
