Specifications
1.Good smooth finish2.Easy to installation
3.After cold rolling, the spirals will be hardened and wear-resistance
Material: Carbon steel, abrasion-resistant steel and stainless steel.
Manufacturing method: welding
faetures:
1)The sectional screw flight presents a single pitch constrution, the outer diameter, inner diameter and the picth can accurately meet the size required once forming is completed.
2)Different types and forms are available like equal diameter / variational diameter, equal pitch / variational pitch and inner hole with supporting lugs, etc..
3)Compared with continuous rolled forming technology, it has the advantages of higher yield, higher precision of forming, higher eligible rate, small quantity order requirement and various supply demand can be met.
4)It particularly applies to the production of big thickness, big size flight made by wearable steel or stainless steel.
