Obnavljanje uporabljenog pijeska pri proizvodnji odljevaka

Metalurgija, 2003
Opseg i svrha ove studije je doprinos razvoju istraživanja procesa obnavljanja pijeska pri pronalaženju okolnosti i uvjeta koji omogućuju zamjenu svježeg kvarcnog pijeska u proizvodnji odljevaka. Na tom polju stvarno stečeno iskustvo u ljevaonicama potvrđuje da se obnavljanje pijeska korištenog za izradu kalupa smatra djelotvornim načinom čuvanja i ...
