| titleOfInvention | Regeneration system of backup roll journal and its method |
| abstract | A regeneration system of a backup roll journal according to the present invention includes a rotating device for forward and reverse rotation of a backup roll using a drive motor; A heating device including a heating housing selectively surrounding the journal portion of the backup roll while reciprocating a predetermined distance and having a heating plate disposed on an inner surface thereof, and a heating controller connected to the heating plate; A welding device installed to weld the reciprocating movement on the journal portion of the backup roll; And a gas mixing device for mixing any one of argon gas or helium, which is a welding protection gas, and carbon dioxide gas to the welding device. n On the other hand, the regeneration method according to the present invention comprises the steps of preheating the journal portion of the backup roll made of iron with a carbon content of 0.8% or less by weight; Regeneratively welding the journal portion of the backup roll while minimizing the amount of hydrogen generated; And post-heating the journal portion of the backup roll at 500 ° C. or lower and slowly cooling at a cooling rate of 20 to 40 ° C. per hour. n n Back-up roll, regenerative welding, rotating device, heating device, gas mixing device |
