In integrated steel plants, torpedo ladle cars (TLCs) transport thousands of tonnes of hot metal each day across extensive rail networks. Any derailment of a filled TLC can lead to catastrophic loss of containment, hot metal–water explosions, serious injuries, and major business disruption. Historically, derailments have occurred mainly due to manual errors in track point setting.
This steelTalk examines how Tata Steel developed and deployed a safety instrumented system to reduce derailment risks during rail-based hot metal transport. The solution uses a multi-barrier approach combining one-touch point setting, track alignment feedback, proximity sensing, optical sensing, alarms, and automatic correction.
The lecture will highlight how this innovation contributed to zero derailments in FY25 due to point burst or side collisions across 112 points in a 62 km hot metal rail network, while generating annual savings of US$ 1,588,140, equivalent to 140 million Indian rupees, and securing one patent from the Government of India.
