The Delta Dist L sensor works in a two step method. Initially, by immersing the lance into the ladle, the slaglevel is detected with the use of a small metal contact
strip. This metal strip provides the initial contact withthe slag. As the probe continues downward with the immersion, it will penetrate through the slag. Then, inside the metal the Delta Dist L sensor with a coil, is utilized for steel detection where a small current runs through it. The characteristics of this current will however dramatically change once the presence of steel is detected. This current change is immediately detected by the latest generation of Heraeus Electro-Nite instrumentation and translated into slag thickness. Finally, the Delta Dist L sensor provides the steel-maker with slag thickness, freeboard and steel bath level with only one sensor immersion.
Correct information on freeboard, slag thickness and bath level in one sensor
• Compatible with existing Celox lance hardware
• Easy to use
• Eliminates safety concerns vs. traditional slag depth measuring
• Measurement time is less than 2 seconds
• Slag depth measures accurately to within +/- 0.5 inch (1 to 2cm)
• Well rinsed slag will enable the most accurate slag thickness measurements possible
The Delta Dist L is typically used in two applications in a modern steel shop.
Ladle — The traditional application is in transfer or processing ladles. The size and shape of these ladles is not of relevance to the application of this technology. Precise Metal level can be determined along with slag thickness and freeboard
Electric Furnace — Another successful application of this technology is in an Electric Melting Furnace. Precise metal level is a challenging point to measure. The Delta Dist Technology can afford an operation to routinely make accurate metal level measurements in-situ
