Title:
PROCESS AND APPARATUS FOR PRODUCING METAL INGOTS
Document Type and Number:
WIPO Patent Application WO/2019/138318
Kind Code:
A9
Abstract:
A process for producing metal ingots (L) comprising at least the following steps: a) filling at least one ingot mould (11) with at least one metal charge (CM) in the solid state for the formation of at least one respective ingot (L), wherein said metal charge (CM) has a melting temperature (Tf) that is higher than ambient temperature (Ta), b) melting said at least one metal charge (CM) in the solid state by heating said at least one ingot mould (11) filled with said at least one metal charge (CM) in the solid state up to a heating temperature (Trs) that is higher than or equal to the melting temperature (Tf) of said at least one metal charge (CM) until the metal charge melts, c) solidifying or letting solidify said at least one molten metal charge (CM) into a respective ingot (L) by cooling or letting cool said at least one ingot mould (11) containing said at least one molten metal charge (CM) to a cooling temperature (Trf) that is lower than said melting temperature (Tf) and higher than ambient temperature (Ta) until said molten metal charge (CM) is solidified into said respective ingot (L), d) extracting said ingot (L) from said at least one ingot mould (11), e) reiterating said steps from a) to d), wherein, at steady state, said extracting d) and filling a) steps are carried out when said at least one ingot mould (11) is respectively at an extraction temperature (Te) and at a filling temperature (Trp) each of which is lower than or equal to said cooling temperature (Trf) and higher than said ambient temperature (Ta).
