Abstract
Aiming at the structure features of large copper screw nut with 8.9 tons in weight
the brass screw nut with high strength was successfully manufactured for rolling machine of Nanjing Steel Company through strictly controlling chemical composition in the screw nut and using rotating speed of 870~925 r/min
and pouring at 1 040~1 080 ℃ as well as cooling with water.
