Definitions
- the present invention relates to a vertical Roll stand for hot rolling plants for parallel simultaneous production of rods or wires.
- the facility, which includes said scaffolding, is also Subject of the present invention.
- the system advantageously sees a connection with the Continuous casting line in front.
- the application takes place in a continuous casting and hot rolling plant for parallel simultaneous flow generation of steel bars or wires.
- the system method is designed for parallel simultaneous generation of metal bars or wires from one Continuous casting and for the parallel flow hot rolling of said Continuous casting.
- the most common method concerns casting and flow rolling of billets that gradually rolled thinner until the metal rod or wire reaches the desired has final cross section.
- This process starts with a stick (e.g. 160x160 mm) from an oven with an hourly production of, for example, 37 tons / h.
- a stick e.g. 160x160 mm
- the rolling speed (3 m / min. - 0.05 m / sec.) Is from does not support the rolling stands and causes damage and failures in the rolling means, not least also due to the overheating of the rollers.
- the speed of the in first billet incoming billet about three times be higher than the casting speed.
- metal wire coils also horizontally arranged winding machines e.g. of the type "EDEMBOR" for metal wire with a diameter of ⁇ 5.5 mm can be provided using multiple lines.
- the roll stands must have more than one Continuous casting line are supplied (at least 2 or 3 Lines).
