Copper-clad steel copper liquid coating device

The invention discloses a copper-clad steel molten copper coating device, belongs to the field of copper-clad steel production equipment, and aims to solve the problems that an outlet of a molten copper smelting furnace is blocked, a steel core cannot smoothly penetrate out, and molten copper in the whole furnace is scrapped. Comprising a graphite pump body, a spiral blade shaft, a sealing shell and a crystallizer, the spiral blade shaft is rotationally arranged in the graphite pump body, the graphite pump body is arranged in the sealing shell, an induction coil is arranged on the periphery of the graphite pump body, the top end of the graphite pump body is communicated with a copper smelting furnace, the bottom end of the graphite pump body is communicated with a copper liquid casting hole of the crystallizer, and the spiral blade shaft rotates to pump copper liquid into the crystallizer and attach the copper liquid to the surface of a steel core penetrating through the crystallizer. After being cooled by th
