Embodiment 1

[0013] Non-magnetic steel wire material, the components and weight percentages are as follows:

[0014] 72% pure iron with a carbon content of 0.005%,

[0015] Copper 5%,

[0016] Nickel 13%,

[0017] Manganese 10%;

[0018] The pure iron is smelted in an intermediate frequency furnace, and other components are added to the molten iron, and then the alloy solution is injected into the mold to solidify and form.

[0019] The forming material is forged into a square steel by a forging press to ensure the tightness of the alloy steel, processed by a rolling mill into a non-magnetic alloy steel disc with an outer diameter of 10 mm, and coated with a layer of non-magnetic alloy steel 1 by horizontal continuous casting 3 mm copper conductive layer, and then drawn into the required wire diameter by wire drawing machine as needed.

Embodiment 2

[0021] Non-magnetic steel wire material, the components and weight percentages are as follows:

[0022] 96.2% pure iron with a carbon content of 0.001%,

[0023] Copper 0.5%,

[0024] Nickel 0.3%,

[0025] Manganese 3%;

[0026] The pure iron is smelted in an intermediate frequency furnace, and other components are added to the molten iron, and then the alloy solution is injected into the mold to solidify and form.

[0027] The forming material is forged into a square steel by a forging press to ensure the tightness of the alloy steel, processed by a rolling mill into a non-magnetic alloy steel disc with an outer diameter of 8 mm, and coated with a layer of 4 layers on the non-magnetic alloy steel by horizontal continuous casting. mm of copper conductive layer, and then drawn into the required wire diameter through a wire drawing machine as required.

Embodiment 3

[0029] Non-magnetic steel wire material, the components and weight percentages are as follows:

[0030] 85% pure iron with a carbon content of 0.003%,

[0031] Copper 2%,

[0032] Nickel 5%,

[0033] Manganese 8%;

[0034] Then pour the alloy solution into the mold made in advance, wait for it to solidify and form, take it out, and forge it into a square steel through a forging press to ensure the tightness of the alloy steel, and process it into a non-magnetic alloy steel core with an outer diameter of 8 mm through a rolling mill. A 3 mm copper conductive layer is coated on the non-magnetic alloy steel by horizontal continuous casting. Then it is drawn into the required wire diameter by wire drawing machine as needed.

Abstract

The invention discloses a non-magnet wire material and a non-magnet copper-clad steel wire of electric wire and cable in new material technical domain, which comprises the following steps: allocating non-magnet wire material with mass percent at 72-96.2% ferroferrite with carbon content lower than 0.005%, 0.5-5% copper, 0.3-13% nickel and 3-10% manganese; smelting the ferroferrite through intermediate frequency furnace; adding the other component into hot iron; injecting the alloy solution into mold; clotting; forming; getting the product. This material can be used to produce electric wire and cable non-magnet copper-clad steel wire.

Description

technical field [0001] The invention belongs to the technical field of new materials, and relates to a special non-magnetic steel wire material and a non-magnetic copper-clad steel wire used for electric wires and cables. Background technique [0002] At present, the shielding wires used in wires and cables are mainly copper wire, copper-clad aluminum, aluminum-magnesium alloy, copper-clad steel wire and other materials, but there are different shortcomings in practical applications. The disadvantages of copper wire mainly include the following items: 1. Since the current shielding wire material is pure copper, when the shielding wire is less than 0.15mm, due to the low tensile strength of copper, wire breakage often occurs during use. 2. Due to the low tensile strength of the copper wire, the precision of the equipment is high. 3. In order to ensure that the copper wire does not stop during the production process, most manufacturers adopt to reduce the speed of the equipmen...
