Abstract

The invention discloses a hard-state tin-coated copper-clad steel wire processing technology comprising the following steps: 1, softening a low carbon steel wire, and aligning same; 2, pickling; 3, coating a first nickel coating; 4, copper plating; 5, plating a second nickel coating; 6, tin coating; 7, cleaning; 8, drying; 9, rolling. According to the method, the nickel plating is done before copper plating and tin plating, thus enhancing the bonding force between coatings and the base material; in addition, the copper easy processability is combined with the steel toughness, thus providing excellent toughness and anti-torsion ability.

Description

technical field [0001] The invention relates to a processing technology of hard-state tinned copper-clad steel wire. Background technique [0002] The existing hard tin-plated copper-clad steel wire processing technology generally performs copper plating and tin plating directly on the wire rod after pickling, and the bonding force between the coating layer and the base material is low, which is not conducive to improving the performance of the wire rod. In the prior art, there is an urgent need for a hard-state tin-plated copper-clad steel wire processing technology that improves the bonding force between the coating and the base material and improves the performance of the wire. Contents of the invention [0003] The object of the present invention is to overcome the defects existing in the prior art, and provide a hard-state tin-plated copper-clad steel wire processing technology that improves the bonding force between the coating and the base material and improves the ...
