Abstract:
It was noticed that exploitation characteristics of finished products are highly dependent on metallic base and character of non-metallic stage (size, shape and morphology). It is possible to influence metallic base and non-metallic stage with the help of the so-called structural heritage effect; in other words, the transmission of structural features of burdening materials (first of all - input of modifiers and alloys). It is possible to influence an alloy structure, for example, by changing the melted metal cooling rate, which presents ferroalloy example. So, in order to get heat-resistant aluminum-containing cast-iron, it is highly recommended to use ferroalloy with structure, which can be provided by cooling after alloying with the maximum possible rate.
Such method is used with modifiers industrial-scale production, used in powder wire for steel processing. Methods of modifier quality estimation were tried-out, including high-temperature liquid viscosimetry; granulometric, chemical and phase modifier composition investigation; metallographic investigation of produced metal. Recommendations are given based on exact organization.
