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...
