SUMMARY OF GLASS TEMPERING FURNACE

As we all know, the tempering furnace is a glass processing equipment with non-standard, and how to select a glass tempering furnace also needs to pay attention to skills. Before purchasing glass tempering equipment, we must consider the development of the local market, do a detailed market analysis before purchasing, and also consider the glass plant area, production environment, power situation, etc. of the deep processing enterprise; the tempering furnace is an important equipment of the tempering plant, and it requires a lot of money when purchasing, so the comprehensive performance, after-sales service, and post-maintenance of the glass tempering machine are all important factors to be considered.

Here are the reminders of glass tempering machine you can refer to.

Customize the type and configuration of the glass tempering furnace according to your own market positioning, the required product model and output.

Locate the market and select features

First of all, you should start from considering your tempered glass market and position the tempering furnace function. At present, the main tempering furnaces in the market are: flat tempering furnace, bending tempering furnace, flat tempering furnace with bending section, bending bidirectional tempering furnace, continuous tempering furnace, and unequal arc tempering furnace. Different types of tempering furnaces have different uses, and you can choose the tempering furnace function according to your needs.

For example, the architectural is mainly based on large sheet of flat glass, and the main function to consider is flat tempering. If your glass processing is mainly ordinary float glass, then you can choose a radiation tempering furnace. This type of tempering The furnace can basically meet your daily glass tempering needs, refer to https://www.bolaymac.com/horizontal-radiation-glass-tempering-furnace/;

If you need to process Low-E glass, be sure to choose a convection tempering furnace, because the forced convection system tempering furnace is suitable for processing tempered Low-E glass and coated glass that with different heat absorption rates on up and down sides, so that it can meet the tempering process of high-quality building and furniture flat glass, etc. refer to https://www.bolaymac.com/convection-glass-tempering-furnace/.

The types of tempered glass are: online Low-E glass, offline Low-E (E=0.02) glass, ultra-clear glass, screen printing glass, patterned glass, colored glass, clear glass, etc.

Of course, if you want a wider product coverage, you can consider a flat-bending two-way tempering furnace, which can be used for both flat glass and curved glass. Of course, the cost of this kind of tempering furnace will be relatively high.

Glass processing thickness

Different glass thicknesses will determine the type of blower used in the tempering furnace, resulting in a great difference in the price of the tempering furnace. When you choose a tempering furnace, you must carefully decide whether to start at 4mm or 5mm.

• Glass for construction engineering generally requires a thickness of 5mm to start. If there is Low-e glass, a convection glass tempering furnace with a larger width and a higher loading rate should be selected;
• For interior decoration, the sliding door glass generally requires a thickness of 4mm to start, and there is no Low-e requirement. You can choose a radiant glass tempering furnace with a moderate width and a good loading rate;
• Glass for household appliances is generally made of thin glass, small in size and high in quality. Small-sized single-chamber, double-chamber or continuous glass tempering furnaces can be selected according to output requirements;
• Solar photovoltaic glass generally uses thin glass with a thickness of 2.8mm-3.2mm, with a fixed size and large output, which is suitable for continuous glass tempering furnaces;
• Automobiles, instruments, etc. belong to special glass, and special tempering furnaces are required.

Once the market direction is determined, the performance of the glass tempering furnace is also determined. Coupled with the production capacity requirements expected by the operator, the model of the glass tempering furnace is completed, and the corresponding configuration can also be determined.

Capacity matching

The production capacity of the tempering furnace should match the estimated annual comprehensive output. Taking the BolayMac tempering furnace as an example, the production capacity of 5mm Low-E glass [e≥08] is 15-18 batches/hour, and the annual output is about 1.5 million square meters. For glass enterprises can calculate the required tempering furnace capacity according to the estimated annual output, so as to choose the appropriate tempering furnace model.

Site area

Different furnace types, such as flat tempering furnace, bending tempering furnace, flat and bending tempering furnace, double-chamber furnace, continuous furnace, etc., have great differences in longitudinal length. Customers should select the type according to the actual reserved area. In addition, Not only the placement of equipment, but also the space required for production, the placement of glass before loading and finished products after unloading, etc.

Power load

The installed power of different furnace types is different. Taking 4mm white glass tempering as an example, the installed power of 2000x3000mm radiation furnace is about 400KVA, and the installed power of 2440×3660 convection furnace is about 630KVA. Enterprises should consider the installed capacity and expansion of transformers accordingly.

Competitors’ equipment

In consideration of differentiated competition, the size of tempering furnace selection is generally larger than that of regional competitors. For example, the size of the surrounding competitors’ furnace is 2440x3660mm, and recommended for selection should be 2440x4200mm or 2500x5000mm.

In order to meet the quality requirements of the market

The tempered glass produced has high-quality flatness and uniform particle. Quality is the key to your success.

Glass tempering furnace operation importance

The operation of the glass tempering furnace should be intelligent, simple and easy to operate, reduce the dependence on people, improve the quality and yield, and reduce the production cost.

Glass tempering furnace stability

The glass tempering furnace must operate stably and ensure that the equipment operates smoothly under normal conditions, so as to fully guarantee the customer’s production requirements; if the equipment fails frequently during operation, it will not only increase the loss rate of the float glass, but also reduce the production efficiency, increase production costs, and even cause delays or changes in product delivery time, damage reputation, and seriously damage the interests of producers.

Glass tempering furnace is the main equipment of the entire glass processing plant

Tempering furnace requires a lot of money when purchasing, and there are restrictions on inspection and maintenance. Therefore, when purchasing a glass tempering furnace, the comprehensive performance of the tempering equipment, after-sales service, and maintenance are all factors to be considered. In fact, if you choose the right one, there is almost no problem with the glass tempering furnace when the operation is correct.

Energy saving of glass tempering furnace

How to make your glass tempering furnace more profitable?

In the cost of factory electricity, the general tempering furnace occupies the largest proportion; good comprehensive energy-saving technology can save you considerable electricity expenses. For glass tempering above 4mm, the main energy consumption unit is the heating section, and the heat required to heat the glass is constant. Reducing the heat loss during the operation of the equipment is an important way to control energy consumption. The heat loss of the heating section mainly comes from the furnace wall and the heat transfer of the convection structure. BolayMac tempering furnace adopts special technology of thermal insulation technology and the latest thermal insulation materials, and the connecting part of thermal insulation cotton is also specially treated, which increases the thermal insulation performance of the furnace body, minimizes heat loss and reduces operating costs.

The glass tempering furnace for the production of tempered glass is a high-energy-consuming equipment. In the production cost, apart from the cost of the glass sheet, rental, and labors, the biggest cost is the electricity bill. Therefore, when choosing a tempering furnace, you must choose an energy-saving type, which saves more money per square meter. 1 kWh of electricity is equivalent to earning more. Therefore, improve resistance to market price wars.

Conclusion 

The glass tempering furnace is determined to purchase according to its actual production needs and future development plans. Whether the funds are sufficient or not, and the determination of the route of the later development plan, all affect the selection of the tempering furnace. It is best to find a specialist to do a detailed market analysis and give you professional advice before purchasing.
