The problem of cracking cores dutiny casting piston in moulds

Popis výsledku v původním jazyce

The article deals with pistons casting made from aluminium alloy. Pistons are casting at steel mould with steel core. The casting is provided by gravity casting machine. The each machine is equipped by two metal moulds, which are preheated above temperature 160°C before use. The steel core i salso preheated by flame. The metal moulds and cores are heated up within the casting proces. The temperature of the metal mould raise up to 200°C and temperature of core is higher. The surface of the core is treated by nitration. The mould and core are cooled down by water during casting proces. The core is overheated and its top part is finally cracked despite its intensive water cooling. The life time cycle of the core is decreases to approximately 5 to 15 thousands castin, which is only 15 % of life time cycle of core for production of other pistons. The temperature analysis of the core is presented by the article.
