Here is an introduction to the application cases of infrared heating lamps in the glass industry: Annealing of flat glassIn flat glass production, the glass cools rapidly after coming out of the high-temperature tin bath, which causes stress inside the glass. If annealing is not performed, the glass is easy to break during subsequent processing and use.A large flat glass manufacturer uses twin tube halogen heat lamps for annealing. They install industrial infrared heat lamp in the annealing kiln and accurately control the power and distance of the quartz halogen infrared heater lamps according to the thickness of the glass and the annealing requirements. For example, for flat glass with a thickness of 6mm, the replacement infrared halogen lamp is set to 20-30cm from the glass surface, and the power is adjusted to a suitable level so that the temperature of the glass rises uniformly to about 550℃ during the annealing process. At this temperature, the stress inside the glass is effectively released, and the strength and stability of the flat glass after annealing are greatly improved, and the scrap rate is reduced by about 30%.Optical lens manufacturingOptical lenses have extremely high requirements for shape accuracy and internal stress.ceramic heating elements play a key role in the annealing process after lens grinding.An optical lens manufacturer uses Short Wave Infrared Quartz Heating Lamps for annealing. They use a high-precision temperature control system combined with an infrared heating lamp to heat the lens to 400 – 450℃. Because the infrared heating lamp heats evenly, the lens will not be deformed due to local overheating during the annealing process. By precisely controlling the heating time and temperature, the stress inside the lens is well eliminated, the optical performance of the lens is guaranteed, and the qualified rate of the product has increased from about 70% to more than 90%.Glassware blowingIn the production process of glassware, the glass blank needs to be heated to a suitable softening temperature before blowing.A glass handicraft factory uses twin tube industrial infrared heat lamp to preheat the glass blank. Surround the infrared heating lamp around the blank, and by adjusting the power and irradiation time of the heating lamp, the glass blank reaches the softening temperature in a short time. For example, when making a glass vase, the blank is heated to about 800℃, at which time the plasticity of the glass is enhanced, and workers can easily blow the blank into various exquisite shapes. The use of infrared heating lamps not only improves production efficiency, but also makes the wall thickness of glassware more uniform, and the appearance quality is significantly improved.Automobile windshield manufacturingAutomobile windshields have complex curved shapes and require good thermoforming processes during the molding process.Automobile glass manufacturers use quartz infrared halogen heat lamps in the thermoforming process. IR Heating Lamps are installed above and around the mold. When the glass is placed on the mold, the Short Wave Quartz Infrared Heating Elements are turned on to quickly heat the glass to about 650℃. Because the Industrial Infrared Heat Lamps can provide uniform heat, the glass can fit the curved surface of the mold well, and the manufactured windshield has high shape accuracy. In addition, in the subsequent tempering process, because the initial state of the glass is good, the impact resistance of the tempered windshield is also improved, which effectively ensures the safety of the car during driving.Tempered glass productionTempered glass needs to be quickly heated and cooled at high temperatures to form surface compressive stress, thereby increasing the strength of the glass.A construction glass manufacturer uses halogen quartz ir heating lamps in a tempered glass production line. They set the tungsten halogen lamps in the tempering furnace to quickly heat the glass. For example, for architectural tempered glass with a size of 1.5m×1.5m, the glass is heated from room temperature to about 630℃ in a few minutes by an Electric Infrared Heat Lamp, and then air-cooled and quenched. Due to the uniform heating process, the glass forms a uniform compressive stress after tempering, and the strength is 4-5 times higher than that of ordinary glass, which can well meet the requirements of architectural safety glass.
