Effects of Continuous Casting Mould Vibration Feeding Strip on the Slab Structure

Abstract:

Continuous casting mold feeding steel strip is a new technology to improve the organization and the equiaxed crystal ratio of casting slab. It is researched in one Steel Mill taking low carbon steel Q235B, 250 * 1600mm billet as the research object. Effects of the vibration feeding steel strip on the slab structure and performance is studied. Results show that, porosity in the center of cast billet and macro segregation of dispersion decreased through the continuous casting mould vibration feeding steel strip technology, which can improve the quality of macro structure and reduce the chemical heterogeneity shaft direction to the regional and then improve the plasticity in thick rolling plate.
