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 …

Development of High-Strength Composites with Sustainable Fibers for Structural Applications
… up to 30% fiber loading were achieved without nozzle clogging, though higher fiber loading negatively impacted mechanical properties. This study also investigates the potential of CNT incorporation in asphaltene-derived carbon fibers and the impact of carbon fiber reinforcement to enhance the …

Effect of Dispersion on Rheology and 3D Printing of Chitosan-Graphene-Titanium Dioxide Composites
… systems faces challenges, particularly nozzle clogging. This paper explores the relationship between dispersion of aggregate size, torsional rheology, and the capacity to print relatively highly particle-filled systems. Various characterization methods, including torsional rheology, …

Colloidal and Polyelectrolyte Inks for Direct -Write Assembly of 3D Periodic Structures
… involves ink deposition through a fine scale nozzle that is robotically controlled using a 3-axis stage. Central to this approach is the design of inks that are capable of flowing through deposition nozzles of varying size and then ""setting"" immediately to facilitate shape retention of the …

Additive Manufacturing Filled Polymer Composites for Environmental Contaminants: Material Extrusion Processing, Structure and Performance
… recovery during printer retractions, leading to nozzle clogging. Lower 20% w/w loading was more conducive to larger production printing due to lower viscosity, longer viscosity recovery times for retractions and thus generally a wider processing window. While altering twin screw processing …

MOLTEN STEEL INTERACTIONS WITH TUNDISH LININGS AND REFRACTORY GLAZES
<p>"In the final stages of casting, molten steel is in contact with two main 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 …
