The paper presents results of reaction kinetics investigation of crystallization processes of refined, modified with Sr and Sb as well as filtered silumin destined to casting of fire-fighting equipment. It has been determined an effect of performed upgrading processes of: refining, modification and filtering on changes of mechanical properties (R_m, A₅, HB and KCV) of the AlSi11 (AK11) alloy. There were performed metallographic examinations of the upgraded alloys and flooded foamed filters. It has been proved, that developed and set into production upgrading technology of the AlSi11 (AK11) alloy enables casting of fire-fighting equipment, complying with rquirements of the European Union.
