Electromagnetic field impact on the structure of continuous casting of grey cast iron

Purpose: The main aim of investigations was to describe the influence of the electromagnetic on the structure of grey cast iron obtained in the continuous casting process. Design/methodology/approach: To investigations the grey cast iron ingots a continuous casting laboratory stand was used. The stand contains continuous casting mould with inductor of rotate electromagnetic field. The research includes also the metallographic researches on scanning electron microscope and investigations of usable properties i.e. measurements of hardness and machinability. Findings: The results of investigations and their analysis show possibility of unification of flake graphite morphology in cast iron structure, and distribution of hardness on cross-section of ingot and its machinability. Research limitations/implications: In further research, authors of this paper are going to application of introduced method of continuous casting with use of electromagnetic field in industrial tests. Practical implications: The work presents method of unification of structure and properties, which are particularly important in continuous casting. Uniform morphology of flake graphite in structure of cast iron ingots for automobile industry is very important in viewpoint of machinability. Originality/value: Contributes to improvement in quality of grey cast iron continuous casted ingots.
