ROLLS PRODUCTION METHOD FOR ROLL WELDING

The manufacturing method of the rolls for roll welding is used, for example, in manufacturing panel radiators for power transformers of up to 1600 KVA. The rolls are obtained from two different rolls, a support roll and a cover roll. Cutting bars from a plate, heating them to a temperature of 850-90...

description	The manufacturing method of the rolls for roll welding is used, for example, in manufacturing panel radiators for power transformers of up to 1600 KVA. The rolls are obtained from two different rolls, a support roll and a cover roll. Cutting bars from a plate, heating them to a temperature of 850-900 degrees C, rolling, adjusting at ends and shaping them on both sides, obtain the cover roll. The thermal treatment is then applied, which consists of heating the roll to a temperature of approximately 1020 degrees C, water-cooling it during 2 seconds, bringing it to 450 degrees C for 4 hours, then cooling it slowly (in the furnace). Then, after shaping it after the support roll, the cover roll in pressed on the support roll.
