Abstract
Between an intermediate roll unit and a dimensioning finishing roll unit of a continuous light-section or wire rod rolling train, a multifunctional section is provided with three parallel lines and at least the first and second rolling lines having rolling blocks and substantially all of the lines including cooling sections and/or temperature equalization sections. Via distributing guides and 180° loop forming path segments, the workpieces are selectively directable from the first line to the dimensioning finishing rolling unit without traveling over the second and third lines and to the dimensioning finishing rolling unit after travelling over all or part of the second and third lines.
Claims14
A continuous light-section or wire rod rolling train comprising at least one intermediate rolling unit, a dimensioning finishing rolling unit, a cooling section following said dimensioning finishing unit, a temperature equalization section following said cooling section, and a multi-functional variable path section between said intermediate rolling unit and said dimensioning finishing rolling unit, said multi-functional variable path section comprising three substantially parallel processing lines including:
- a first line connected to an output side of said at least one intermediate rolling unit and including in succession an intermediate rolling block, a first distributing guide, at least one cooling section or temperature equalization section and a second distributing guide having one outlet delivering workpieces to said dimensioning finishing rolling unit;
- a second line having at least one intermediate rolling block and delivering workpieces to said second distributing guide;
- and
- a third line connected to another outlet of said second distributing guide and provided with at least one cooling section,
- said rolling train further comprising:
- a first 180°-loop-forming path segment connecting an outlet of said first distributing guide to said third line;
- a third distributing guide connected to said first 180°-loop-forming path segment in said third line and a fourth distributing guide connected to said third distributing guide in said third line;
- a second loop-forming path segment connected between said other outlet of said second distributing guide and said third line;
- a third 180°-loop-forming path segment connected between one outlet of said fourth distributing guide and said second line between the intermediate rolling block and the cooling section thereof;
- and
- a fourth 180°-loop-forming path segment connected between said third line and said second line upstream of the intermediate rolling block thereof whereby said workpieces are selectively directable from said first line to said dimensioning finishing rolling unit without traveling over said second and third lines and to said dimensioning finishing rolling unit after traveling over all or part of said second and third lines.
A method of operating a continuous light-section or wire rod rolling train comprising at least one intermediate rolling unit, a dimensioning finishing rolling unit, a cooling section following said dimensioning finishing rolling unit and a temperature equalization section following said cooling section, said method comprising passing workpieces from said intermediate rolling unit through a multifunctional variable path between said intermediate rolling unit and said dimensioning and finishing rolling unit and comprised of three substantially parallel processing lines including a first line connected to an output side of at least one intermediate rolling unit and including in succession an intermediate rolling block, a first distributing guide, at least one cooling section or temperature equalization section and a second distributing guide having an outlet delivering workpieces to said dimensioning finishing rolling unit, a second line having at least one intermediate rolling block and delivering workpieces to said second distributing guide, and a third line connected to another outlet of said second distributing line and having at least one cooling or temperature equalizing section and connected to said second line, and directing said workpieces selectively from said first line to said dimensioning finishing rolling unit without traveling over said second and third lines and to said dimensioning finishing rolling unit after travelling over all or part of said second or third lines.
