Abstract
Inventia se refera la un procedeu pentru realizarea bilelor morilor de macinat ciment, de dimetru cuprins între 30 si 50 mm, utilizînd o fonta alba aliata cu 18% Cr, permiâînd obtinerea unei structuri uniforme în toata masa bilelor respective. Metalul lichid este turnat într-o forma alcatuita dintr-un model de poliestiren expandat si alice metalice magnetizabile. Atît tasarea alicelor, cît si turnarea metalului lichid, se fac întrun cîmp magnetic. Dupa solidificarea metalului lichid, si cînd bilele au ajuns la temparatura de 800-900 degree C, acestea sînt scoaser din forma si dirijate la un cuptor de tratament termic care are o temperatura de 98 degree C.
