Metallurgy, Vol.42 No.1 January 2003. -

In work opinions of form incompatibility were executed during process of production of casting articles from spheroidal cast iron. Using the quality tools such as the Ishikawa diagram and the Pareto-Lorenz analyses one identified often-appeared defects and, were identified and qualified. Identification of critical points of productive system was executed and the range of correcting workings was qualified. On basis of data from analysis of causes of occurrence of incompatibilities and appointed critical points system of control of quality was worked out for serial and isolated production. Use of statistical method of casts in connection with active control of quality and selection of productive stages for serial production of casts from spheroid cast iron caused lower level of defects, and in economic aspect contributed to the reduction of costs of connected production with low level of quality.
