One of the greatest challenges in the direct casting of low carbon steel strip is the production of material with mechanical properties similar to those obtained via conventional strip production routes. A fundamental understanding of the microstructure evolution from solidification through to the final product is of critical importance in this endeavour. Experimental work was carried out using a special apparatus to establish links between heat transfer, nucleation, solidification, strip microstructures and mechanical properties. This information was used in conjunction with the actual microstructures and properites of strip obtained from a full scale development plant to define the breadth of product opportunities possible from the direct casting of low carbon steel strip.
