Rheological Characteristics of Molten Metal for Casting Design

Collaborative Research: Manipulating the Contact and Solidification of Molten Metal in Continuous Casting

A technology to enable continuous casting of molten metals, in a single step, to the specifications of the designer is being developed[7]. For example, casting aluminum foil in a single step could reduce CO 2 emissions to the atmosphere by 250,000 tons per year, in the US alone. Furthermore every kilogram of aluminum saved by reducing manufacturing waste translates into electricity saved at the...

Adaptive Fuzzy Control Design for the Molten Steel Level in a Strip Casting Process

Y. J. Zhang, L. B. Wu, H. Y. Zhao, X. D. Hu, W. Y. Zhang, D. Y. Ju, School of Materials and Metallurgy, University of Science and Technology Liaoning, China This paper studies the adaptive fuzzy control problem of the molten steel level for a class of twin roll strip casting systems. Based on fuzzy logic systems (FLSs) and the mean value theorem, a novel adaptive tracking controller with parame...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

On Liquid Metal Wetting of Casting Rings for DC Casting

During air–slip direct chill casting of aluminum alloys, uneven or low air pressure areas at the surface of the porous graphite ring mold, can cause the metal to stick to the graphite ring and produce traces along the billets called vertical drags (VD). To prevent this type of defect, it would be an advantage to decrease the wettability of the graphite ring. It has been shown that nanostructure...
