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...
متن کاملDesign 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...
متن کاملA Transient Simulation and Dynamic Spray Cooling ControlModel for Continuous Steel Casting
IN order to remain competitive in the worldwide market for continuously cast steel, steel producers are finding it increasingly important to implement process control improvements. Through superior production process monitoring and control, producers are improving steel quality and are meeting customers’ requirements for steel size, grade, quantity, and properties at the lowest cost. Computer m...
متن کاملControl issues in continuous casting of steel
Continuous casting plants are highly complex plants whose performance requires reliable mold level control system. Several effects greatly influence the surface quality of the final product and if these are not suppressed sufficiently by the mold level control system, than the production speed, hence the productivity has to be lowered. This paper analyses the most important disturbance and thei...
متن کاملContinuous Casting of Steel
Continuous casting is used to solidify most of the 750 million tons of steel produced in the world every year. Like most commercial processes, continuous casting involves many complex interacting phenomena. Most previous advances have been based on empirical knowledge gained from experimentation with the process. To further optimize the design and improve the continuous casting process, mathema...
