JNE Environmental demonstrates excellent caster andhot mill descalingwater treatment capabilities. by admin. in News. High pressuredescalesprays are critical to the proper performance of continuous casters, roughingmills, andhot mills. Thesesystemsrun at very high volumes (over 150,000 litres per minute) and very high pressures (3,000
Jan 14, 2017·Hot Rollingis employed forrollingof steel slabs tohotstrips inhotstripmills. Like any otherhot rollingoperations,rollingofhotstrip is also a plastic deformation of the material of the slab caused by compressive force applied through a set ofrolls. The cross section of the slab is reduced by thehot rollingprocess.

Buma made the wholeengineering. This contains: / High pressuredescaling/ Liftingrollertable / Chain seesaw; The high pressure descaler has been designed to ensure that future broader and higher slab can be descaled. By the precise setting of the upper scale bar the quality ofdescalingwas again improved.
