Apparatus and method for production of metal elongated products

Apparatus for production of elongated rolled products comprising: - means (6) for producing liquid metal having at a first production rate, - a rolling mill (13) having a second production rate - a continuous casting station (11) located between the steelmaking station and the rolling mill (13), the continuous casting station (11) comprising at least two casting lines (21,19), each line being operable to produce elongated intermediate products, wherein: – a first casting line is directly aligned with (or is configured to directly feed) the rolling mill to feed the roll mill with casted product, and – at least a second laterally not aligned with the rolling mill and not feeding the rolling mill characterised in that the apparatus further comprises: varying means (27) for varying simultaneously the production rate of the first casting line and the production of at least a second casting line depending on the difference between the steelmaking station production and the rolling mill production.
