The goal of tempering is to heat glass uniformly to near its softening point (around 620°C) and then rapidly cool (quench) it with air jets. This creates compressive stress on the surface and tensile stress in the core, resulting in stronger, safer glass. Sin embargo, achieving consistent quality (flatness, low distortion, uniform stress, no breakage) across different glass types (clear, coated, baja emisividad, patterned), espesores, and sizes is challenging. Intelligent control systems aim to address these challenges.
Glass Tempering Furnace Intelligent Control
Here are key aspects and techniques used in intelligent control systems for hornos de temple de vidrio:
Advanced Sensing and Monitoring:
Thermal Scanners/Cameras: Provide detailed real-time temperature maps of the glass surface as it exits the furnace, crucial for identifying non-uniform heating.
Pyrometers: Multiple non-contact temperature sensors strategically placed within the furnace and quench.
Stress Measurement Systems: Online or offline systems (p.ej., using photoelasticity) to measure residual stress patterns
Dimensional/Flatness Sensors: Laser or optical systems to measure glass flatness and warp.
Energy Consumption Monitoring: Tracking power usage of heaters and blowers.
Data Acquisition and Processing:
High-speed collection and storage of data from all sensors, furnace settings (heater power, convection levels, quench pressure, velocidad del transportador), and glass properties (tipo, espesor, dimensiones).
Data cleaning, filtering, and feature extraction to prepare data for analysis and modeling.
Sophisticated Modeling:
