MOLTEN STEEL INTERACTIONS WITH TUNDISH LININGS AND REFRACTORY GLAZES
… types of refractories: the working lining of the tundish used to serve as an intermediate vessel between the ladle and copper mold, and the various glazed carbon-bearing refractories used to control the flow of steel from the ladle to the tundish and from the tundish to the mold. If steel …

Model studies of plasma heating in the continuous casting tundish.
A room temperature water model of a tundish was design, constructed and operated. The model was equipped with a steam heating system that simulates that simulates the tundish plasma heating systems operated by some of the more modem continuous casting plants. Similarity between steam heating in the …

Argon Bubble Behavior in Slide-Gate Tundish Nozzles During Continuous Casting of Steel Slabs
"Argon injection into a tundish nozzle is an efficient and widely employed method to reduce nozzle clogging in the continuous casting process. It also affects casting operation and product quality by changing the flow pattern in the nozzle and mold. The current work combines mathematical modeling …

Enhancing Steel Cleanliness in Tundishes by applying Physical and Mathematical Modeling
The tundish, being the last vessel which stores steel in liquid state, provides the final opportunity to enhance its quality. Hence, it must be ensured that the tundish acts as a refiner rather than a contaminator. It has been noticed that reoxidation of liquid steel from ambient air aspiration …

Designing and modeling of a new continuous steelmaking process
… the subsequent vessels (Reducer, Finisher, and tundish). Continuous de-O, de-S, and alloying would be accomplished in the cone-shaped Reducer before additional de-S and alloy additions as well as inclusion floatation and homogenization in the Finisher would ensure a continuous stream of quality …

Inclusion behaviour in steel flows through convergent nozzles.
… phase particles, a water model using a perspex tundish and an interchangeable glass nozzle has been built. Turbulence has been almost completely removed from the experimental tundish. Hydrogen bubbles electrolytically generated in water have been used to simulate the inclusions in steel and …

Modeling of multiphase turbulent flow in continuous casting of steel
… casting of steel, argon gas injection at Upper Tundish Nozzle (UTN) wall or stopper tip is well known to decrease clogging and remove inclusions. Besides this intended gas injection, gas may be passively sucked into the system by negative pressure development inside of nozzles. The injected gas …

Development of a Novel Thermal Shock test for isostatically Pressed Carbon-Bonded Refractories
… flow-control components such as ladle shrouds, tundish nozzles, and slide gates. Chemical, mechanical, and thermal degradation of these parts can produce severe safety, environmental and economic consequences in steel plants. Standardized tests, however, may not fully characterize the damage …

Inclusion behaviour in the liquid core during continuous casting.
… depth.Although argon stream introduced into the tundish nozzle stream can protect the nozzle blockage, it is not beneficial to the inclusion removal in the sump.

Modeling transient multiphase flow and mold top surface behavior in steel continuous casting
… investigate gas permeating through heated upper tundish nozzle (UTN) porous refractory, including the effects of nozzle geometry, gas thermal expansion, temperature-dependent gas viscosity, and possible gas leakages into unsealed joints. Furthermore, a procedure to predict initial bubble size is …

Modelling of the liquid slag behaviour in the continuous casting mould
… Nozzle (SEN) jet supplying the steel from the tundish to the Continuous Casting (CC) mould. The study includes the very complex phenomenon of argon bubble transport which also affects the behaviour of the slag layer and SEN jet. The model developed in this study is based on the finite volume …
