A method and equipment for continuously producing a high-purity single crystal copper belong to the technical field of new material production. The equipment for producing the high-purity single crystal copper comprises an electronic beam smelting furnace, horizontal continuous casting equipment, a liquid level control block, a thermal insulation crystallizer, traction equipment and the like. The method is that a cut 4N copper cathode plate is conveyed into the electronic beam smelting furnace through a raw material conveying roller way to be smelted and purified on a graphite boat; the purified melt copper directly flows into a thermal preserving furnace through a guide pipe, and a protective gas of nitrogen is filled into the furnace to avoid oxidation; the melt copper passes through the thermal insulation crystallizer and cooling equipment to form a single crystal copper wire blank with a solidification structure; and the wire blank is drawn through the traction equipment, so that the continuous production is realized. The equipment and the method related in the invention can continuously produce the high-purity single crystal copper wire blank and have the advantages of low cost, no pollution, easiness in automatic control and the like, and the produced copper wire blank not only has high purity but also has single crystal performance and is suitable for producing materials of the bonding wires of integrated circuit (IC) encapsulating materials and the like.
