Abstract:Fluid flow in the mold region of the continuous slab caster at Panzhihua Steel is investigated with 0.6-scale water model experiments, industrial measurements, and numerical simulations. In the water model, multiphase fluid flow in the submerged entry nozzle (SEN) and the mold with gas injection is investigated. Top surface level fluctuations, pressure at the jet impingement point, and the flow pattern in the mold are measured with changing submergence depth, SEN geometry, mold width, water flow rate, and argo… Show more
“…The current author has reviewed methods to detect inclusions and operating practices to improve steel cleanliness at the ladle, tundish, and continuous caster. 5,[8][9][10][11][12][13][14][15][16][17][18][19][20] Inclusions arise from many sources, including deoxidation, reoxidation, nitride formation, slag entrapment, chemical reactions, and other exogenous sources. Clues to the mechanism of their origin can be discerned from their composition and shape in the final product.…”

“…Thomas et al 16,17) developed a particle-capture model based on local force balances implemented into computational models of turbulent fluid flow and particle transport. Zhang and Yang 18) presented two approaches to predict the particle entrapment in the full length of a billet caster. The results showed the calculated inclusion distribution in the billet by the full solidification approach agreed with the industrial measurement better than the sink term approach.…”

“…It is considered that the forces acting on the mold are gravitational 2,3) as the standard Froude number can be satisfied at any scale in a model with water. It is also considered that all measures of the holes and hydraulic heights used in the system were varied according to a single scale parameter, this because the kinematic viscosity of the liquid steel at the process temperature (1 600°C) and water, are virtually identical.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
