Trusted by leading global enterprises

Problem Statement

The lifespan and efficiency of furnaces are heavily impacted by refractory wear and hotspots, which lead to costly downtime and repairs.

A leading steel manufacturer faced frequent refractory wear and unplanned furnace shutdowns, resulting in high maintenance costs and reduced productivity. Despite routine thermal checks, minor anomalies and localized hotspots often went unnoticed—shortening furnace lifespan and disrupting operations.

Undetected
hotspot

Undetected hotspots across the furnace shell led to gradual refractory damage, unexpected temperature spikes, and sudden equipment failures. Limited thermal visibility caused early warning signs to go unnoticed, leading to costly downtime and safety risks.

Undetected
wear

Undetected refractory wear gradually weakened furnace integrity, causing uneven heating, rising shell temperatures, and unexpected equipment failures. Small cracks and erosion progressed unnoticed, leading to reliability issues & reduced refractory life.

Missed critical
issues

Critical issues such as rising shell temperatures, refractory thinning, and localized damage were often missed due to limited visibility. These overlooked signs escalated into major faults, causing unexpected failures and reducing overall furnace reliability.

Frequent replacement of refractory

Frequent refractory replacement became necessary as wear, hotspots, and unnoticed damage accelerated deterioration. The lack of early detection increased thermal stress on the lining, shortening its lifespan and driving up maintenance cost and downtime.

Solution

Ripik AI deployed a Vision AI–based Furnace Monitoring System designed to deliver continuous, non-intrusive thermal monitoring of furnace shells and refractory linings.

Specialized Hardware

The furnace monitoring solution is equipped with specialized industrial-grade hardware, including high-resolution thermal and optical cameras designed to withstand harsh furnace environments. These rugged, heat-resistant devices ensure accurate temperature readings, stable long-duration performance, and reliable monitoring under extreme conditions—enabling precise detection of wear, hotspots, and structural abnormalities.

24/7 Furnace Health Monitoring

The system enables 24/7 furnace health monitoring by continuously tracking temperature patterns, shell conditions, and refractory behavior in real time. This uninterrupted visibility helps detect early signs of wear, hotspots, or abnormal heating at any hour, ensuring timely interventions, reducing the risk of sudden failures, and maintaining stable furnace performance throughout operations.

Automated Anomaly Detection and Instant Alerts

The platform automatically detects anomalies such as sudden temperature spikes, localized hotspots, and refractory wear, triggering instant alerts for the plant team via dashboard, WhatsApp, email, and PLC control. These real-time notifications enable rapid response to emerging issues, preventing damage, reducing downtime, and ensuring safe, uninterrupted furnace operations.

Historical video feeds & insightful report

The system provides historical video feeds and insightful reports, enabling teams to analyze patterns and trends in furnace behavior, review past anomalies, track wear progression, and make informed maintenance decisions.

Impact and Validation by End Users

Increase refractory life with furnace monitoring

Effective furnace monitoring helped extend refractory life by maintaining stable temperatures and preventing overheating or thermal shocks. With automated alerts and timely interventions, wear and erosion were minimized. This resulted in a longer refractory lifespan, lower maintenance costs, and improved furnace reliability.
