Study on drawing force of flux-cored wire

By analyzing the drawing stress of flux-cored wire(FCW),a new model for the calculation of the drawing force for FCW was formed.The factors that influence drawing force were also discussed.Mechanical properties of the steel strip,deformation of flux-cored wire,the hole size of dies,drawing speed,friction and lubrication conditions had obvious effects on the drawing stress.The drawing stress increased with the speed rise at low speed.At moderate speed the drawing stress decreased.The drawing stress did not change when the speed increase further.
