DEVELOPMENT OF METHODS FOR QUALITY CONTROL OF DUCTILE IRON WITH SPHEROIDAL GRAPHITE
Keywords:
casting, spheroidal graphite ductile iron, quality control, Lost Foam casting, sand mold, isothermal hardening, austempering, magnetic measurementsAbstract
Two methods for controlling the quality of spheroidal graphite cast iron in castings are described. Mechanical properties are suggested to be checked during testing of cast V-shaped samples, and for non-destructive testing of the optimal combination of structural constituents of cast metal at isothermal quenching (austempering) it is proposed to use a sensor that signals a certain ratio of the paramagnetic and ferromagnetic phases in the cast metal.
