Abstract
The purpose of this article is to carry out a statistical analysis quality of structure formation of castings of body parts made of gray cast iron.
The magnetic method of non-destructive quality control of the coercive force was used as a criterion for the analysis of the quality under production conditions was carried out. The evaluation was carried out on two types of parts: transfer case housings and gear change housings made of SCH15, SCH18 and SCH20 cast irons, respectively. Both types of parts have similar wall thickness.
The observed phenomenon is associated with deviations in the method of injection the modifier (silicomanganese) and its uneven assimilation throughout the mass of the metal. Thus, according to local X-ray spectral analysis, the distribution concentration of these elements is especially inhomogeneous in castings with a higher level of coercive force (0,07...2.09% Si and 0,04...2.15% Mn). The shape of the inclusions is the same for different Hc. Despite the close concentration in the distribution of the main components over the cross-section of the castings, we found that the reason for the difference between multiple readings obtained when measuring the coercive force is an increased proportion of graphite inclusions, oxides and sulfides. The use of such a non-destructive control method will make it possible to identify zones in products with deviations in structure and to more thoroughly analyze the possibility of defect formation (pore and crack formation).
