Abstract

A three-dimensional numerical model for fluid flow was solved by computer for the continuous thin slab casting process with an electromagnetic brake system. The effects of the electromagnetic brake on the meniscus properties and solidified shell thickness were investigated along with the flow pattern. The electromagnetic brake reduced the jet stream velocities of the liquid steel but increased the amount of the upper stream. It contributed to the increase of the velocity and temperature on the meniscus. It eliminated the cold spot region that generally exists at the rear of the nozzle, the optimum required electromagnetic current for this effect being calculated to be 200 amperes. The average solidified shell thickness was improved by the application of the electromagnetic force.
