Example Embodiment
[0023] Example 1:
[0024] An industrial production process for high-strength copper-tin alloy contact lines, which includes the following steps:
[0025] Step 1: Double molten ditch three-body melting furnace smelting.
[0026] Add cathode copper plate to the melting area of the three-body melting furnace (the cathode copper plate is not less than No. 1 standard copper), and add dry charcoal as a covering agent, the covering thickness is 120mm, in the insulation area is covered with graphite scales, the coverage thickness is 100mm, the intermediate interval oxygen chamber is covered with dry charcoal, the thickness is 150mm, and the slag and mixing operation are carried out according to the actual working conditions of the smelting, and the tin element and zinc element are added after the furnace condition is stabilized, and the alloy raw material is completely melted, the heat preservation is 10min, so that the elements are mixed evenly, The melting temperature is 1160 °C, the z...
