摘要

Control of true steel level in the tundish during casting is desired in order to maintain the correct pressure head andthus provide a stable flow to the mold. Also the control of tundish draining prevents slag carryover and can increaseyield at each end of cast sequence.At Steel of West Virginia (part of the SDI Group), it was understood that to be able to measure the true steel runninglevel and control the drain level at the end of casting would be a great benefit during production at their three strandbillet caster.This paper sets out to show how an evaluation process was started to find the best method to determine steel level inthe tundish and to prevent the steel level dropping low enough to allow slag to enter the mold. Also how the decisionwas taken and a real time molten steel measurement system was installed and by utilizing the resulting data in theprocess, how slag in the mold was removed as an issue, how lost production was reduced and how consistent steellevel has provided constant casting speeds and improved stream integrity, all leading to realized quality improvements.Other areas discussed within the paper will be the training of operational staff, the difficulties to be overcome when firstinstalling new equipment and how these teething problems were cured by close co-operation between the steel plantand the equipment suppliers.In conclusion the paper will discuss the production improvements achieved, production cost savings at the plant andhow the generated data was integrated into the plants process control system.
