Claim 0:
1. A secondary cooling apparatus (12) in a machine (10) for continuous casting of metal products (P), wherein each metal product (P) is cast, contained, and guided along an axis of movement (X), said secondary cooling apparatus (12) comprising:
a plurality of cooling assemblies (G) disposed in sequence along said continuous casting machine (10),
wherein each of said assemblies (G) comprises a plurality of cooling units (17) each provided with one or more nozzles (18) disposed along the axis of movement (X),
wherein said cooling units (17) of each assembly (G) are adjacent to each other to cover a width at least equal to a maximum width of the metal product (P) which is cast in the continuous casting machine (10),, wherein
each of said nozzles (18) of each of the cooling units (17) comprises two or more orifices (19) for delivering a refrigerant fluid (L) onto the metal product (P) to be cooled,
one orifice (19) of a nozzle (18) being associated with a feed line (24) for feeding the refrigerant fluid distinct from another of the two or more orifices of the same nozzle (18),
homologous orifices (19) of distinct nozzles (18) of a same cooling unit (17) being associated with the same feed line (24),, wherein, said secondary cooling apparatus (12) also comprises a feed circuit (21) for feeding said cooling units (17) and has a plurality of valve assemblies (22), wherein each valve assembly (22) is associated with a respective one of said cooling unit (17), said feed circuit (21) being connected to at least one main feed conduit (25) configured to fluidically connect pumping means (23) to said valve assemblies (22), wherein said at least one main feed conduit (25) comprises a single flow interception means (30) configured to control a flow rate of refrigerant fluid (L) passing in said at least one main feed conduit (25) toward said cooling units (17).
