International ClassB21B 041/06Foreign Application Priority Data1997-11-10 DEAbstractA process for applying a defined surface roughness to a metal strip, especially steel strip, for preventing the sticking of strip during subsequent annealing in a bell-type annealing installation includes cold rolling the metal strip in at least one reversing roll stand. The cold rolled metal strip is then guided to a temper rolling stand for wet rolling the cold rolled metal strip through at least one pass for applying the defined surface roughness to the metal strip. For this purpose, the flattening rolls of the temper rolling stand are replaced with rough rolls.Field of SearchBY USE OF ROLLER OR ROLLER-LIKE TOOL-ELEMENTWith modification or control of temperature of work, tool or machine Including cooling To reverse-roll the workpiece With cleaning or conditioning of tool, or lubrication of tool or machine Including successively-acting roller-couples WITH CLEANING, DESCALING, OR LUBRICATION OF WORK OR PRODUCT Mechanical cleaning Lubricating "Rolling" Between disclosed rollers Roller or roller-like tool-element of particular configuration With working at or below 120`C or unspecified cold working Heating step follows cold working With tempering, ageing, solution treating (i.e., for hardening), precipitation hardening or strengthening, or quenching With tempering, ageing, solution treating (i.e., for hardening), precipitation hardening or strengthening, or quenching | |
