Abstract

A method for producing rolled products includes providing two parallel lines downstream of a continuous casting, for conveying profiled supply sections that converge together at least at a single first rolling station. A plant for implementing the method is also provided.

First claim

The invention claimed is:

1. A method for producing rolled products, the method comprising the following steps:
a) generating together, simultaneously and at an identical speed, at least two supply metal section bars by a continuous casting process;
b) sending together the two supply metal section bars simultaneously and at an identical speed to at least a first rolling station of a rolling mill, the first station including at least one cage provided with rolling rollers;
c) rolling together the two supply metal section bars simultaneously and with identical rollers of an identical rolling cage of the first rolling station;
d) sending together the two metal section bars exiting the first rolling station simultaneously and at an identical speed to a second rolling station including at least one cage provided with rolling rollers;
e) rolling together the two section bars of step d) simultaneously and with an identical rolling cage of the second rolling station;
f) sending the two metal section bars exiting the second rolling station simultaneously and at an identical speed to a third rolling station including at least one rolling cage provided with rolling rollers; and
g) rolling together the two section bars of step f) simultaneously and with identical rollers of an identical rolling cage of the third rolling station.

2. The method according to claim 1 , which further comprises providing the first rolling station as a roughing station with horizontal axis rollers.

3. The method according to claim 1 , wherein, in the generating step, the at least two supply metal section bars are generated with identical cross sectional areas.
