Apparatus and method for production of metal elongated products

摘要

An apparatus for producing elongated rolled products contains a steelmaking station for producing liquid metal having at a first production rate, a rolling mill having a second production rate, and a continuous casting station located between the steelmaking station and the rolling mill. The continuous casting station contains at least two casting lines, each line being operable to produce elongated intermediate products. A first casting line is directly aligned with the rolling mill to feed the rolling mill with casted products, and at least one second casting line not aligned with the rolling mill and not feeding the rolling mill. The apparatus further contains a varying device for varying simultaneously the production rate of the first casting line and the production rate of the at least one second casting line depending on a difference between the steelmaking station production rate and the rolling mill production rate.

主权项

1. An apparatus for producing elongated rolled products, the apparatus comprising:
a steelmaking station for producing liquid metal at a first production rate; a rolling mill having a second production rate; a further processing unit disposed downstream of said rolling mill for further processing products made from the liquid metal; a continuous casting station disposed between said steelmaking station and said rolling mill, said continuous casting station containing at least two casting lines, each of said at least two casting lines being operable to produce elongated intermediate products, including billets or blooms, said at least two casting lines including a first casting line directly aligned with said rolling mill to directly feed said rolling mill with casted product and at least one second casting line never aligned with said rolling mill, said at least one second casting line configured to bypass all rolling mills including said rolling mill and feed said further processing unit disposed downstream of said rolling mill; and varying means for varying simultaneously a production rate of said first casting line and a production rate of said at least one second casting line depending on a difference between the first production rate and the second production rate.
