چکیده
Although continuous casting is the state‐of‐the‐art method in steelmaking, ingot by bottom teeming has kept its relevance, for example, area of specialty steels. The main challenge to meet ever‐increasing quality requirements demanded customers. Regarding high‐performance steel applications, purity with respect content nonmetallic inclusions thereby special interest. Herein, foam templates tailored geometry are designed and manufactured selective laser sintering. Different coating techniques based on carbon‐bonded alumina slurries applied replicate structures miniature cube cylindrical geometry. evaluated regarding porosity, pore size distribution, bulk density, mechanical strength, shrinkage resulting filters. Suitable processing routes selected manufacture prototype batches near‐net‐shape Finally, feasibility applying a flame spray tested. First samples batch tested industrial bottom‐teeming casting.

Alumina nanostructured coating for corrosion protection of 316L stainless steel
Nanostructured alumina thin films were coated on stainless steel by Sol-Gel dip coating method. In order to prevent crack formation, Al2O3 films were kept in a solvent bath immediately after coating to reduce the rate of drying. Effects of calcination temperature and withdrawal speed on structural properties were analyzed using XRD and SEM. Topography and thickness of coat...

متن کاملAlumina Inclusion Behavior during Steel Deoxidation
A computational model based on classic homogenous nucleation theory, thermodynamic analysis and numerical simulation, has been developed to study steel deoxidation by aluminum in a low carbon aluminum-killed steel ladle, which calculates the nucleation and time evolution of the alumina inclusion size distribution due to Ostwald ripening, Brownian collision and turbulent collision. Starting with...
