We consider the problem of dynamic coupling between the rapid thermal solidification and mechanical compression of steel in twin-roll steel strip casting. In traditional steel casting, molten steel is first solidified into thick slabs and then compressed via a series of rollers to create thin sheets of steel. In twin-roll casting, these two processes are combined, thereby making control of the ...

During the solidification, and then cooling, generally a shrinkage gap or mechanical interaction (grip or slip) can occur between the casting and the mold. The character of interaction is decided by the shape of casting. Both these phenomena occur in most real castings. Shrinkage gap, and specifically its width, determines the heat flow between cast and mold, while the mechanical interactions l...

Introduction: Water is thought to be vital for the development of plate tectonics because it lowers viscosities in the asthenosphere and enables subduction. However, the following issue persists: if water is necessary for plate tectonics, but subduction itself hydrates the upper mantle, how is the upper mantle initially hydrated? Here we present models demonstrating that processes associated wi...

The Electroslag Remelting (ESR) process works with a consumable electrode, which is melted through a slag layer into a water-cooled mould applying alternating electric current. The ESR process produces large ingots of high quality, by controlled solidification and chemical refinement. It is important to predict, how certain process parameters affect the structure and chemical composition of the...
