Unveiled at Glasstec 2024, the world's leading trade fair for the glass industry, the project addresses the urgent need for enhanced reliability in the critical lehr process. This furnace, vital for annealing and cooling flat glass, usually lasts for 15 to 20 years. However, any downtime in the process halts production completely, as highlighted by industry studies, where a mere 1-minute power interruption can lead to up to 6 months of production loss, often requiring equipment replacement, and costing up to €200,000 per day.
Saint-Gobain together with Schneider Electric has developed the first open automation solution for the lehr process. The proof of concept (POC) is powered by Schneider Electric's open automation technology, EcoStruxure Automation Expert (EAE) which decouples hardware and software, allowing devices and equipment to be freely connected across architecture layers, regardless of manufacturer.
The project also enhances safety and efficiency in glass manufacturing, with EAE enabling autonomous drive capabilities and representing a major advancement in distributed intelligence. The ‘smart' drives control the two glass-pulling motors, allowing autonomous operation and critical process decision-making at the equipment level, including deciding which motor will pull the glass, performing quality checks and paving the way for predictive maintenance.
Crucially, the solution's modular design means it is easy to deploy worldwide with its plug-and-play interoperability enabling up to 50% reduction in engineering, testing and commissioning times. This intrinsic scalability enables the construction company to realize value at its sites and see exponential value globally.
