How To Distinguish between Good And Bad Glass Tempering Machine Furnaces? What Is The General Selection Techniques for Glass Tempering Furnace?

Glass tempering furnace is the main equipment for producing tempered glass, and different types of glass tempering furnace equipment have different uses. As we all know, glass tempering furnaces are non-standard equipment, and we also need to master the skills when choosing tempering furnaces

1. How to distinguish between good and bad glass tempering furnaces

The reason why we ask about the classification of good and bad glass tempering furnaces is simply because we want to purchase glass tempering furnaces with better quality, so that our tempered glass products can meet customer requirements and ensure quality. As a non-standard equipment, when choosing a glass tempering furnace, we should consider our own factors, fully consider market sales and current development positioning. For example, in the field of architecture, there are differences in the demand for tempered glass. Building curtain walls require glass sizes to be relatively neat, but due to tight delivery times, we should choose a double chamber furnace to better meet our production needs; For the requirements of tempered glass for indoor doors and windows, the single area of glass is small and the quantity is large. Generally, single or double rooms can be selected.

2. Tips for selecting glass tempering furnaces

2.1. Manufacturer strength

When choosing a glass tempering furnace, full consideration should be given to the production technology level and strength of the manufacturer. Some large tempering furnace manufacturers have mature experience and standards in equipment research and development, production technology, production lines, and product services, which can provide us with better technical support and product experience. Luoyang Yuegao Glass Technology Co., Ltd. has an experienced R&D and design team, strong manufacturing capabilities, and a complete service system. It is a specialized enterprise engaged in the research and development, manufacturing, and service of glass deep processing equipment. The manufacturer's strength is trustworthy. Welcome to visit and learn more.

2.2. Self demand

The choice of tempering furnace is mainly based on the above mentioned, and it needs to be customized according to the products we make. The best one is the one that is suitable. Even if other products have outstanding performance, they are not suitable for us if we cannot use them. Whether we are choosing new or second-hand equipment, we should make a reasonable choice based on our own market positioning and product characteristics. At present, the main forced convection tempering furnaces on the market are: flat tempering furnace, curved tempering furnace, flat bending bidirectional tempering furnace, curved bidirectional tempering furnace, and unequal arc tempering furnace. Different types of tempering furnaces have different uses, and you can choose the function of the tempering furnace according to your needs.

2.3. Product configuration

Tempering furnace equipment, like cars, also requires high and low configuration. Electrical components, frequency converters, industrial controls, PLCs, ceramic rollers, and other brands have different qualities. Some second-hand tempering furnaces have better configurations than many new furnaces and are more durable to use than new ones.

2.4. After sales service

It is generally recommended to purchase tempering furnaces manufactured by tempering equipment manufacturers with rich production experience, who generally have their own research and development bases and manufacturing plants, so that the progressiveness technology and quality control of products can be guaranteed, and more perfect after-sales services can be provided. Our equipment and service system of Yuegao Glass is comprehensive, which can meet the needs of daily technical guidance, product guidance during the production process, and after-sales service, allowing you to use it in a more directional way.

2.5. Manufacturing process

Of course, how to distinguish between good and bad glass tempering furnaces can also be analyzed from the perspective of manufacturing technology. The manufacturing process of products is updated and updated with the continuous improvement of equipment technology. When choosing a glass tempering furnace, we should also consider the corresponding manufacturing process. For example, the selection of convection surfaces and convection processes. These factors are also crucial for selecting a forced convection tempering furnace, as they not only affect product performance but are also crucial for cost control.

At present, forced convection tempering furnaces can be divided into two modes: upper half convection and full convection

(1) Half convection mode: The convection furnace with a semi convection configuration only uses forced convection heating for the upper part, while traditional radiation heating is used for the lower part. The upper heating efficiency is higher, making it easy to achieve balanced heating up and down. Suitable for tempering high-quality glass and various online and offline coated glass.

(2) Full convection mode: There is a qualitative difference from the traditional structure of strengthening upper convection by adding balance tubes, which uses a mixed heating method of convection and radiation. The full convection mode uses both upper and lower forced convection heating, fundamentally solving a series of heating problems caused by the different radiation rates on the upper and lower surfaces of Low-E glass. Compared to the semi convective model, the fully convective model is better.

2.6. Ceramic roller conveyor inside the furnace

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

2.7. High temperature convection curve control

The control of high-temperature convection curve reflects the temperature control ability of the heating area of the furnace body. Uneven heating of glass is prone to phenomena such as inadequate tempering and furnace explosion. When purchasing, attention should be paid to the side placement of the convection fan, which makes it difficult to control the temperature curve on both sides of the furnace. When choosing a forced convection tempering furnace, enterprises that have done well in this regard should be considered.

2.8. Heating system

Many tempering furnaces use ordinary radiation furnace heating wires, and good manufacturers will use (CrNi), which is more than 10 times the price of ordinary radiation furnace heating wires. This material has a longer lifespan and excellent stability, and can basically achieve long-term non replacement of heating wires.

2.9. Auxiliary system

The wind pressure auxiliary control system in the tempering section can reduce the dependence on the operator's experience, improve production efficiency, and reduce the defect rate caused by human factors. Good manufacturers use imported industrial electrical appliances and temperature module controls to ensure system reliability, all nickel chromium stainless steel furnace inner lining, and box material. Generally, electrical products used in the market are of lower grade, and there are significant differences in internal materials.

2.10. Installation environment

The above are all considerations for product performance. In addition, we also need to consider our own factory environment and area. Because the forced convection tempering furnace heats the glass inside the furnace through convection fans, its heating furnace body is higher than that of a typical radiation furnace. In addition, the tempering furnace also has a large external fan, so this needs to be considered when selecting a factory building. Of course, there are also our order requirements, the required production capacity to output ratio, and so on.

The above is the analysis of glass tempering furnace manufacturers on how to distinguish between good and bad glass tempering furnaces.
