Abstract

Sposób wytwarzania linek bimetalowych polega na tym, że drut płaszczowy stal/Cu o średnicy w zakresie 3,0 do 1,6 mm, o udziale wagowym miedzi 15 do 70% charakteryzujący się wytrzymałością na rozciąganie Rm = 340 - 700 MPa i wydłużeniem A100 = 2 - 24% po wyżarzeniu w temperaturze 650°C w czasie 3 h w atmosferze ochronnej zawierającej 5% wodoru i 95% azotu, poddaje się operacji ciągnienia z gniotem jednostkowym 12 - 16% na ciągarce wielostopniowej do uzyskania drutu o średnicy w zakresie 1,0 do 0,1 mm z gniotem sumarycznym 98 - 99%, który następnie wyżarza się elektrycznie w piecu przelotowym, stosując natężenie prądu 77 - 95 A, przy prędkości ciągnienia wynoszącej 5 m/s w atmosferze ochronnej zawierającej 99,2% azotu, aż do uzyskania drutu o średnicy końcowej w zakresie 1,0 do 0,1 mm, posiadającego wytrzymałość na rozciąganie Rm = 350 MPa i wydłużenie 21 - 24%, i tak wytworzony drut poddaje się skręcaniu w wielożyłową linkę.The method of producing bimetal ropes is that a steel / Cu sheathed wire with a diameter in the range of 3.0 to 1.6 mm, with a copper weight share of 15 to 70%, characterized by tensile strength Rm = 340 - 700 MPa and elongation A100 = 2 - 24% after annealing at 650 ° C for 3 hours in a protective atmosphere containing 5% hydrogen and 95% nitrogen, is subjected to a drawing operation with a 12 - 16% unit crease on a multi-stage drawing machine to obtain a wire with a diameter of 1.0 up to 0.1 mm with an aggregate joint of 98 - 99%, which is then electrically annealed in a continuous furnace using a current of 77 - 95 A at a drawing speed of 5 m / s in a protective atmosphere containing 99.2% nitrogen, until obtaining wire with an end diameter in the range of 1.0 to 0.1 mm, having a tensile strength Rm = 350 MPa and an elongation of 21 - 24%, and the wire thus produced is twisted into a multi-stranded cord.
