Measuring temperature in the cold rolling process is crucial for several reasons. First, while cold rolling occurs at room temperature, variations can affect the material’s properties, such as ductility and strength. Monitoring temperature helps ensure the metal remains within optimal ranges to prevent issues like cracking or uneven deformation. Second, temperature influences the friction between the rollers and the metal, impacting energy consumption and the quality of the final product. Additionally, consistent temperature management can enhance equipment lifespan by preventing overheating and reducing wear. Overall, precise temperature control contributes to improved product quality, efficiency, and safety in the rolling process.
