This utility model discloses a melting and casting device for recycling Babbitt alloy from a pear-shaped steel wire rope sheath. It includes a housing, a medium-frequency induction furnace housed within the housing, and a casting mold. The medium-frequency induction furnace comprises a furnace body, a capacitor box, and a power supply box. The furnace body has a hollow structure extending vertically, with a lifting port at the top and an open bottom. The furnace body is designed with three layers from the outside in: an outer layer of heat insulation plate, a middle layer of induction coils arranged in a spiral pattern using hollow copper tubes, and an inner layer of fireproofing mud. The power supply box is electrically connected to the capacitor box and the induction coils. The casting mold is located below the furnace body. Eddy currents are generated inside the pear-shaped steel wire rope sheath suspended in the furnace by the induction coils, generating heat to heat the sheath. When the heating temperature exceeds 230°C, the Babbitt alloy inside the sheath melts rapidly, forming a flowing liquid that drips directly into the casting mold below. Finally, it cools and is demolded, achieving effective recycling of the alloy.
