Abstract

Metodă pentru obţinerea unei ţagle de alamă cu un conţinut redus de plumb ce prevede prelucrarea unui produs finit sau semifabricat din alamă tradiţională prin îndepărtarea aşchiilor şi obţinerea aşchiilor tradiţionale de alamă şi efectuarea unui tratament de fragmentare pe aşchiile tradiţionale de alamă menţionate pentru a obţine fragmente tradiţionale de alamă; efectuarea unui tratament de îndepărtare a plumbului pe respectivele fragmente tradiţionale de alamă pentru a obţine fragmente de alamă cu un conţinut redus de plumb; topirea într-un cuptor a unei încărcături care conţine fragmentele de alamă menţionate cu un conţinut redus de plumb; obţinerea unei ţagle prin extrudarea directă sau inversă a produsului topit.
