Thermo-mechanical behavior of steel in the continuous casting process from meniscus to caster exit
… surface. The model considers the effects of mold cooling, secondary cooling, bending and unbending on the mechanical loading history of the strand. The thermal behavior of the model is calculated using boundary conditions from CON1D, in the mold and in secondary cooling. The thermal boundary …

Correlation for measured mold heat flux and CON1D simulations for feasible operating conditions in thin-slab continuous casting
… of high quality slabs in a safe environment. Cooling in steel continuous casting comprises primary cooling in mold followed by secondary cooling in spray cooling zone. In this work, various parameters affecting heat flux are studied, first in mold from plant measurements and second in spray …

Thermal hydraulic design and analysis of a large lead-cooled reactor with flexible conversion ratio
… through an enhanced reactor vessel auxiliary cooling system (RVACS) complemented by a passive secondary cooling system (PSACS).

Modeling transport phenomena and uncertainty quantification in solidification processes
… This semicontinuous process consists of primary cooling as the metal is pulled through a water cooled mold followed by secondary cooling with a water jet spray and free falling water. To gain insight into this complex solidification process, a fully transient model of DC casting was developed to …

Control of constrained moving-boundary process with application to steel continuous casting
… as well as operational safety. Most of the cooling spray control techniques currently used in the steel industry are effectively open-loop due to the lack of reliable measurements to enable feedback. Namely, the high temperatures, the variable surface emissivity, the scale formation, and the …

Hot ductility of TWIP steels
… of such factors as chemical composition, cooling rate and thermal cycle on hot ductility. Using a cooling rate of 60oC/min after heating to 1250oC, ductility was generally <40% RA (Reduction of Area) indicating that these high Al TWIP steels it will be difficult to cast without transverse …

Advances in the application of passive down-draft evaporative cooling technology in the cooling of buildings
A passive down-draft evaporative cooling (PDEC) tower is a component that is designed to capture the wind at the top of a tower and cool the outdoor air using water evaporation. While several different types of this particular system exist, PDEC tower with spray was studied in that it is flexible, …

Study of spray-cooling control for maintaining metallurgical length or surface temperature during speed drop for steel continuous casting
… are open-loop. The main reason is that the spray cooling droplets impinging on the high temperature surface induce steam clouds, which make temperature measurement unreliable. However, for operations limited by the casting speed, or for steel grades sensitive more to centerline rather than surface …
