Scale formation and its removal in hot rolling process

Jun 28, 2018· There are two kinds of scales relevant in rolling mills – sticky and dry scales. Sticky scales can be removed most effectively by use of high pressure water jets upto 450 bar. Dry scales can be removed from the surface by application of descaling systems with low distances of the descaling nozzle to the material.
