Abstract
The main processing factors that control the solidification of castings, and conse- quently, microstructure and mechanical properties, are: chemical composition, liquid metal treatment, cooling rate and temperature gradient. In this work, the influence of melt tem- perature; cleanout cycle, continuous casting direction (horizontal / vertical) and super-cooler size on tensile strength and elongation percentage of continuous cast copper alloys has been characterized by tensile machine and confirmed by microstructure examination. A significant difference on tensile strength and elongation percentage has been observed by changing the processing parameters. By optimizing these parameters, the mechanical prop- erties of continuous copper alloys can be substantially improved. As a particular example, super cooler size could improve the elongation of samples from 38% to 45% or cleanout cycle could improve the tensile strength of samples from 532 MPa to 561 MPa.
