Glass tempering furnace is a key equipment in the glass production line, which directly affects the operating efficiency of the entire production line and the quality of glass products. Reasonable selection of glass tempering furnace can not only improve production efficiency and extend the service life of equipment, but also effectively save energy consumption and reduce operating costs.
Principles of glass tempering furnace equipment selection
1. Capacity matching principle
The design capacity of the glass tempering furnace must match the actual capacity of other links in the production line. If the capacity of the tempering furnace is too large, it will cause waste of energy and labor; if the capacity is too small, it will restrict the efficiency of the entire production line. Therefore, when selecting, it is necessary to combine the actual situation of the production line to select a better tempering furnace specification.
2. Process compatibility principle
The tempering process requirements of different glass varieties are different, so the design of the tempering furnace must be compatible with the process of the required tempered glass variety. For example, although the tempering processes of flat glass, automotive glass, laminated glass, etc. have something in common, the parameter settings in the heating, cooling, and transportation links are different. Therefore, it is necessary to select a suitable tempering furnace model based on the company's existing and future product planning.
3. Energy-saving and environmental protection principles
With the increasing attention paid to energy conservation and environmental protection, the glass industry is also facing higher environmental protection requirements. Tempering furnaces are high-energy-consuming equipment, and equipment with high energy efficiency ratio and low pollution emissions should be given priority, which can not only reduce operating costs but also meet environmental protection requirements. In addition to the energy-saving performance of the equipment itself, the design of energy-saving links such as waste heat recovery should also be considered.
Precautions for selecting glass tempering furnace equipment
1. Clarify the size requirements of the tempering furnace
Glass tempering furnaces of different specifications have large differences in size. For example, the length of the car window glass tempering furnace is usually 6-9 meters; the flat glass tempering furnace can even reach more than 30 meters. Therefore, before selecting the model, it is necessary to accurately understand the requirements of the production line for the glass size to avoid the inability to produce normally due to inconsistent sizes.
2. Determine the heating method of the tempering furnace
The heating methods of the tempering furnace mainly include gas heating, electric heating and radiation heating, etc. Different heating methods differ in thermal efficiency, cost and maintenance requirements. Gas heating has high efficiency and low cost, but there are certain safety hazards; electric heating is clean and environmentally friendly, but it consumes a lot of electricity; radiation heating has high precision and uniform heating, but the investment cost is high. Enterprises need to weigh and choose according to their actual situation.
3. Pay attention to the material and thermal insulation performance of the furnace body
The material and thermal insulation performance of the tempering furnace body are directly related to the accuracy of furnace temperature control. Stainless steel and refractory materials are commonly used furnace body materials with good high temperature resistance and oxidation corrosion resistance. In addition, the use of high-quality insulation layers can effectively reduce heat loss and improve energy utilization efficiency.
4. Check the automation level of the control system
Modern glass tempering furnaces should be equipped with a control system with a high degree of automation to accurately control key process parameters such as heating, cooling and conveying speed. When selecting, it is necessary to understand the functions of the control system in detail, such as whether it has functions such as remote monitoring, data acquisition and fault diagnosis, and how the software and hardware can be upgraded.
In short, when selecting glass tempering furnace equipment, it is necessary to fully consider capacity matching, process compatibility, energy saving and environmental protection, and pay attention to specific matters such as size requirements, heating methods, material properties, control systems and maintenance services. Lay the foundation for improving production efficiency, ensuring product quality and reducing operating costs.
