Abstract
A hot rolling train with a walking beam furnace, a reversing stand following the walking beam furnace and possibly shears and/or descaling devices, as well as a subsequent hot strip finish-rolling train for manufacturing thin, austenitically rolled hot strip is retrofitted with an equalizing furnace provided between the reversing stand and the hot strip finish-rolling train, wherein the equalizing furnace has a number of receiving locations for strips to be heated for equalizing the strip in order to ensure a total heating time for each preliminary strip which is a multiple of the rolling time and the hot strip finish-rolling train.
Claims10
A hot strip rolling train comprising a walking beam furnace, at least one reversing stand following the walking beam furnace, and shears and descaling units, and a hot strip finish-rolling train downstream of the reversing stand for manufacturing thin austenitically rolled hot strip, further comprising, for one of reducing a maximum rolling speed and further lowering a rolling strip thickness, an equalizing furnace between the reversing stand and the hot strip finish-rolling train, wherein the equalizing furnace comprises a plurality of receiving locations for heating the preliminary strips to equalize the temperature thereof, wherein the equalizing furnace is configured to ensure a total heating time for each preliminary strip which is a multiple of a rolling time of the strip in the hot strip finish-rolling train.
