Process and device for reverse rolling metal strips

Coiler furnace for a hot strip

There is disclosed a rolling arrangement including a rolling stand and a preceding descaling means. In order to obtain a perfect surface quality while maintaining a high energy content of the rolling stock the descaling means is arranged immediately in front of the rolls of the rolling stand and is formed by a rotor descaling means. The liquid jets emerging from the rotor descaling means and impinging on the rolling stock are directed opposite to the rolling direction. The liquid impinging on the point of impact of the liquid jet on the surface of the rolling stock, after impingement has a flow resultant which--projected on the rolling direction--has a component opposite to the rolling direction.

Rolling arrangement

A hot strip coiler furnace is disclosed, which comprises a furnace hood, a drivable coiler drum, which is accommodated in the furnace hood and has a strip-receiving opening for receiving the leading end of the incoming strip, and a strip-receiving guide, which has a delivery end adjacent to the strip-receiving opening of the coiler drum when it is in a strip-receiving position. In order to permit the hot strip to be completely pulled into the coiler furnace, it is proposed that a strip-delivering guide for the outgoing strip is provided, which guide protrudes or is adapted to be introduced into the generally triangular space which is defined by the coil of strip and the incoming or outgoing strip.
