摘要:
A process and an apparatus for preparing steel stock before hot rolling. The steps of preheating the stock (5, 16, 22) in a first induction furnace (6) so that the preheated stock enters a subsequent descaling apparatus (7) with a surface temperature of T1≧1000° C.; descaling the preheated stock by a plurality of water jets in a descaling apparatus (7); direct subsequent heating of the descaled stock in a second induction furnace (8), where the descaled stock enters the second induction furnace (8) at a temperature T2 which is ≧Tcurie of the stock and heating in the second induction furnace 8 is either in a largely inert or largely reducing protective gas atmosphere; passing the heated stock in a rolling mill (9), where the heated stock enters the rolling mill (9) at a temperature 1220° C.≧T3 1050° C.
