Steel Mill Refractory Monitoring

Monitoring Solutions from Viper Imaging provide an accurate, reliable temperature measurement solution to ensure plant safety and increase efficiency.

AOD – BOF – EAF – LMF – Ladles – Torpedo Cars – Water Wall Leak Detection

Viper’s Steel Mill Refractory Monitoring System uses thermal imaging cameras to monitor in real time and alarm for temperature anomalies. View, analyze, record, and trend critical data for key assets in the process.

Review some use case examples below!

The Viper Ladle Refractory Monitoring system uses FLIR thermal imaging to monitor the health of a ladle through its lifecycle.

Steel mills worldwide use refractory-lined ladles to store and transport molten steel. A key benefit of the Viper monitoring system is that it allows users to input a ladle ID, and ViperVision Max software will monitor the health of the ladle through its lifecycle.

Over time, the refractory linings degrade or develop cracks that allow the ladle’s outer shell to be exposed to excessive temperatures. If not caught in time, a molten metal breakout can occur, threatening the lives of plant personnel and causing unnecessary downtime and significant damage to equipment. Viper’s Ladle Refractory Monitoring System uses thermal imaging cameras to monitor the ladle in real-time and warn of excessive shell temperature resulting from refractory degradation – ultimately preventing a breakout.

The cooling water system is an inherent part of every EAF, and there is an industry need for effective and reliable water leak prevention as well as leak detection. When water gets trapped below molten steel, it often results in two explosions.

  1. Steam ejects from below the surface – projecting molten metal and slag
  2. More severe explosion from the rapid ignition of H2 and CO gas inside the EAF

Viper’s monitoring system using FLIR thermal cameras easily detect water and determine the source. Scroll to the bottom of the page to see thermal images of discovered leaks.

Use thermal imaging cameras to monitor the shell temperature of process vessels.

A multi-camera system will monitor the shell temperature of the AOD (Argon Oxygen Decarburization) and VOD (Vacuum Oxygen Decarburization) vessels. A key area of interest is often the shell directly behind the AOD tuyeres.

Built with FLIR thermal cameras, Viper monitoring solutions continuously provide the critical data needed for informed decision-making. The greatest advantage an operator can have is an insight into their entire process from beginning to end. When FLIR thermal cameras are paired with Viper Imaging, customers get better visualization, control, and communication. Learn how our system adds another layer of safety to your facility and processes.

Featured case studies include EAF Water Wall Leak Detection and Steel Ladle Refractory Monitoring.

Viper's System Solution

This illustration portrays a typical installation for Viper’s Ladle Refractory Monitoring system using FLIR A-series cameras. Viper’s design places three cameras around the ladle and a fourth camera to monitor from underneath. The camera’s digital data stream is connected via Ethernet to the ViperVision control system. ViperVision software controls all camera functions, collects temperature data, displays thermal images, and analyzes data.

Add the ViperVision Max Software package for the ability to view, analyze, record, and trend critical data for key assets. This package includes a Control Communication module and a Database/Reporting module.

Case Study: Designing the Future of Steel Ladle Refractory Monitoring

The Refractory Engineer says he relies on the alarm system within the [ViperVision] software for protection from breakouts. He begins every day by reviewing a thermal image of each ladle looking for abnormalities.

System Solution Components

FLIR cameras are integrated with the ViperVision software which directly communicates with most industrial platform controllers. Every thermal imaging camera is mounted in an industrial camera enclosure that uses the appropriate purge and pressurization to protect the camera equipment. Viper Imaging provides solutions for Class I and Class II environments (Division 1 or 2).
