Simulator Based Design of Secondary Cooling Zone Control in Continuous Casting

Real-time Model-based Spray-cooling Control System for Steel Continuous Casting

This paper presents a new system to control secondary cooling water sprays in continuous casting of thin steel slabs, CONONLINE. It uses real-time numerical simulation of heat transfer and solidification within the strand as a software sensor, in place of unreliable temperature measurements. The one-dimensional finite-difference model, CON1D is adapted to create the real-time predictor of the s...

The Design of a Gamma-Ray for Detecting Mushy Zone in Tomographic Sensor Continuous Casting

The y-ray tomographic sensor invented by the CastScan consortium at MIT for the non-invasive real time monitoring of the solidification front in the continuous casting of metals is a new industrial computed tomography (CT) tool. The sensor potentially offers great economic benefits to the continuous casting industry by preventing break-outs, and increasing productivity and efficiency through op...

Design and Implementation of a Real-time Spray Cooling Control System for Continuous Casting of Thin Steel Slabs

Robust and accurate control of secondary cooling is vital to the successful operation of any caster and the production of high quality products. This is especially important in thin slab casters, because high casting speed and a tight machine radius often requires carefully-prescribed temperature profiles to avoid various cracking problems. This can be achieved only by successful control of the...
