Abstract Three kinds of p roduction p rocesses of steel wire galvanized by dipp ing for rope with 1 770, 1 870, 1 960 MPa
strength level and A, AB, B kind of Zn coatmass are introduced such as galvanizing by dipp ing after drawing, drawing after
medium galvanizing by dipp ing and drawing after galvanizing by dipp ing. Production p rocess is selected according to the
consumers’different requirements, characteristics of equipment and technology condition; sem i finished diameter of steel
wire galvanized by dipp ing is made according to different p roduction p rocess and strength level.
Keywords steel wire for rope; galvanizing by dipp ing; drawing; p rocess
