High borosilicate tempering furnace: What should the price and purchase of the tempering furnace be like?

1. Position the market and choose the function. First consider your tempered glass market and position the function of the tempering furnace. The forced convection tempering furnaces on the market are mainly: flat tempering furnaces, curved tempering furnaces, flat and curved two-way tempering furnaces, curved two-way tempering furnaces, and unequal arc tempering furnaces. Different types of tempering furnaces have different uses. You can choose the function of the tempering furnace according to your needs.

2. High borosilicate tempering furnaces, such as large flat glass, are mainly used in construction, and flat tempering is the main function to consider. For example, Shencheng's LD-AJ series uses jet forced convection heating technology for flat tempering equipment, which can meet the tempering processing of high-quality flat glass for construction and furniture; the types of tempered glass are: 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 consider flat and curved two-way tempering furnaces, both flat and curved glass. Of course, the cost of this tempering furnace will be higher.

3. The choice of convection mode, convection surface and convection process. At present, the forced convection tempering furnace has been recognized by more and more people in the industry. Compared with the traditional radiation tempering furnace, it has many advantages and is gradually favored by customers. These factors are also very important for the selection of forced convection tempering furnaces, which not only affect the performance of the product, but also are crucial for cost control. At present, forced convection tempering furnaces are divided into two modes: upper half convection and convection. Among them, convection is a very expensive one, but the tempering furnace launched by Shencheng is a good representative of forced convection furnaces.

4. High-temperature convection curve control of high-boron silicon tempering furnace. The control of high-temperature convection curve reflects the temperature control ability of the heating area of ​​the furnace body. Unevenly heated glass is prone to tempering failure and furnace explosion. It should be noted when purchasing that due to the horizontal placement of the convection fan, the temperature curves on both sides of the furnace body are not well controlled. When choosing a forced convection tempering furnace, consider companies that do well in this regard.

5. The choice of heating system (electric heating wire). Many tempering furnaces use ordinary radiation furnace heating wires, and good manufacturers will use CrNi. The price of this material is more than 10 times that of ordinary radiation furnace heating wires, with long service life and good stability, and it can basically achieve the purpose of not changing the heating wire for many years.

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

7. The wind pressure auxiliary control system of the tempering section can reduce the dependence on the experience of operators, improve productivity, and reduce the defective rate caused by human factors. The main control department of a good manufacturer uses imported industrial electrical appliances, and the temperature module control ensures the reliability of the system. The furnace and the box are made of nickel-chromium stainless steel. Generally, the grade of electrical appliances used on the market is relatively low, and the internal materials vary greatly. It is also necessary to pay attention to factors such as plant selection and supporting conditions.

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