Molten metal casting method for cable wire end

The invention relates to a molten metal casting method for a cable wire ends. the method adopts a hot casting way and comprises the steps of: cutting cable wire with a certain length, making a cable wire end into a broom head shape, and carrying out surface treatment; casting the cable wire broom head into a cone shape with an alloy solution with certain temperature and certain mass ratio; sealing the bottom of a casting mould with clay during the casting process to prevent the alloy solution from leaking from gaps; forming a test sample after cooling and then carrying out the integral wire break tension test of the cable wire. The cable wire sample made by the method does not slide or move away relative to alloy during the process of the tension test, and thus, the test is reliable; and the wire head alloy tested by the method can be melted in a furnace for recycle, and the test cost is reduced by 70%.
