This utility model relates to the field of tellurium ingot casting technology, and specifically discloses a tellurium ingot casting device, including a furnace, a chute, a casting sump, and a casting machine platform. The furnace includes a crucible, a cover plate, insulating bricks, a heating device, a thermocouple, a first outer shell, a support, a rotating shaft, a connecting shaft, a leak detection port, and a pressure cap. The furnace is mounted on the support and connected by the rotating shaft. The cover plate is connected to the first outer shell through the connecting shaft. The first outer shell is made of stainless steel. The leak detection port is located on the side of the furnace near the chute. The crucible is made of silicon carbide graphite and is fixed to the first outer shell by the pressure cap. The insulating bricks and the heating device are located between the crucible and the first outer shell. This utility model adopts a two-stage zoned temperature-controlled melting and impurity removal method from bottom to top. Impurities easily float to the surface and solidify, resulting in good stratification with the molten tellurium. The impurity removal effect is good, the operation is simple, and the tellurium yield is high. The entire operation process is controlled by PLC, with a high degree of automation, avoiding frequent contact between operators and the high-temperature molten material, and creating a friendly working environment.
