Continuous Casting of Steel
Continuous casting is used to solidify most of the 750 million tons of steel produced in the world every year. Like most commercial processes, continuous casting involves many complex interacting phenomena. Most previous advances have been based on empirical knowledge gained from experimentation with the process. To further optimize the design and improve the continuous casting process, mathema...

متن کاملA New Mechanism of Hook Formation during Continuous Casting of Ultra-Low-Carbon Steel Slabs
The initial stages of solidification near the meniscus during continuous casting of steel slabs involve many complex inter-related transient phenomena, which cause periodic oscillation marks (OMs), subsurface hooks, and related surface defects. This article presents a detailed mechanism for the formation of curved hooks and their associated OMs, based on a careful analysis of numerous specially...
متن کاملTransient Fluid Flow and Superheat Transport in Continuous Casting of Steel Slabs
The turbulent flow of molten steel and the superheat transport in the mold region of a continuous caster of thin steel slabs are investigated with transient large-eddy simulations and plant experiments. The predicted fluid velocities matched measurements taken from dye-injection experiments on full-scale water models of the process. The corresponding predicted temperatures matched measurements ...
متن کاملFlow Control with Ruler Electromagnetic Braking (EMBr) in Continuous Casting of Steel Slabs
Electromagnetic forces are an important tool to control fluid flow in the mold, combined with other casting conditions, nozzle, and mold geometry. Methods include static magnetic fields (local and ruler EMBr), and time-varying magnetic fields, such as electromagnetic stirring, (EMS), multi-mode EMS, electromagnetic level stabilizers (EMLS), and electromagnetic level accelerators (EMLA). Optimal...
