Abstract

The new developed Laser-Measuring system shows a unique way to measure refractory lining thickness and 3D-profile in hot steel casting ladles from inside the ladle. The Laser-measuring system has an innovative, yet simple and rugged design that allows immersion of a laser head into a hot Steel Casting Ladle with surrounding temperatures of more than 1100 °C and surface temperatures up to 1700°C. The system’s laser-beam rapidly scans the lining thickness of the entire surface, collecting millions of data points that are generated in a wide range of computer displays from simple tabular reporting to a virtual walk-through of configurable 3D images. Due to the optimal Scan Angle Gap and crack detection is possible as well as Determination of critical areas below the slag line which cannot be seen by conventional laser technology from outside the ladle. By means of precise determination of the taphole-geometry an automated sand filling of the tap hole can be made. This new development allows steel makers to measure refractory-lining thickness in Steel casting ladles in less than three minutes, This measuring system can provide steel makers with improved safety, increased ladle availability and capacity, extended refractory life and cost savings in energy, material and the maintenance of hot Steel Casting Ladles.
