Optimization of the process parameters for the manufacture of cyrogenic ferritic as-cast spheroidal graphite cast iron

摘要

Problem and target. State of knowledge: Melting and magnesium treatment; inoculation; problems during manufacture; influence on properties and material behaviour of ferritic EN-GJS; summary of the initial situation; remaining problems. Target of the research work and method of solution: Investigation on the magnesium vaporization behaviour. Main tests: parameters; variables. Other tests: investigation on the magnesium vaporization behaviour. Test results: magnesium vaporization behaviour; inoculation; influence on notch impact; casting defects.
