The results of studies on the effect of particles of metal-abrasive sludge used as a potential modifier of gray cast iron are presented in the article.The influence of metal and non-metal components of the sludge is clarified and the prevailing influence of metal particles is established during the studies. The assumption is made about the mechanism of the effect of particulate additives from the viewpoint of self-organization phenomena in ultradispersed systems. The strength increase of cast iron CЧ20 as a result of the introduction of slurries into the melt reaches up to 25%.

The article presents the results of computer simulation of the crystallization of castings from high-speed steel R6M5, intended for the manufacture of cutters and gear shaping tools in the conditions of OJSC “Minsk Gear Plant”. The use of modeling made it possible to optimize the gating system, reduce this volume of the profitable part by 30–35 % and increase the yield of suitable casting, which made it possible to reduce the consumption of expensive alloying elements introduced into the melt to compensate for burnout during melting and casting.

The composition, structure, methods of receipt of ultradisperse materials (UDM) and the prospect of their application in engineering procedures of foundry production are considered. Positive influence of UDM when entering in fusion on structure and properties of the gray cast iron intended for production of castings of motor group is established.
