Abstract

PURPOSE:To improve the maintenance characteristic and productivity of a titled installation by installing direct water-cooled steel rolls into the throats connecting plural catenary furnaces and making the rolls changeable through the lower parts of the throats. CONSTITUTION:A strip 1 is conveyed in catenary annealing furnaces 2 and throats 4 by supporting rolls 5 (direct water-colled steel rolls), and the waste combustion gas by burners 6 is exhausted to the outside of the furnaces 2 through flues 3. When the pickup (or build-up) of scale on the supporting rolls 5 occurs, an opening type door 7 is opened by fluid pressure cylinders 12, and a traverseable and elevatable supporting roll changer (dolly) 8 is moved into the line, thence the rolls 5 are attached and detached, while water is kept flowed to the rolls 5. After the detachment of the rolls, the device 8 is moved to the outside of the line, and the door 7 is closed.
