JZ80

JZ80

The seven roll straightener is used to straighten the bending of bar or tube created in the rolling process. It has obvious effect in solving bar head or tail bending, eliminating slight ellipticity and removing oxide scale. The material of bar or tube includes Carbon tool steel, carbon structural steel, alloy tool steel, alloy structural steel, spring steel, stainless steel, bearing steel, titanium chromium nickel alloy etc..
