10. A processing method for a continuous high-temperature ingot melting equipment, characterized in that: The following steps are involved: S10. A continuous high-temperature ingot smelting device as described in any one of claims 1 to 9 is provided; S20. For all high-temperature melting chambers on the same transfer section, synchronously control the plunger rod to insert into the discharge port at the bottom of the melting crucible to seal the discharge port; put the raw material into the melting crucible in the corresponding high-temperature melting chamber through the feeding device, evacuate the high-temperature melting chamber and gradually heat it to the working temperature to melt the raw material; S31. The ingot crucible is placed on a crucible translation vehicle located in the feed chamber; S32. Open the feed isolation door mechanism, control the crucible translation mechanism to translate the crucible translation vehicle carrying the ingot crucible to the transfer section directly below the guide tube of the corresponding high-temperature smelting chamber; S33. Repeat steps S31 and S32 according to the number of high-temperature smelting chambers on the corresponding transfer section until there is an ingot crucible under the guide tube of each high-temperature smelting chamber; S40. After the raw material in the high-temperature melting chamber is completely melted, the plunger rod of the corresponding high-temperature melting chamber is controlled to lift and separate from the discharge port of the melting crucible, so that the raw material liquid in the melting crucible flows into the corresponding ingot crucible through the guide pipe; S50. Open the partition isolation door corresponding to the transfer section, control all the crucible translation vehicles to move to the cooling section through the crucible translation mechanism, and then close the partition isolation door; S60. Repeat steps S20 to S50 S70. Repeat steps S20 to S60 synchronously in other transfer segments; S80. When the number of workpieces in the cooling section reaches a preset number, the discharge isolation door mechanism is opened, the crucible translation mechanism is controlled to transfer the workpieces that have completed cooling to the discharge chamber, and the discharge isolation door mechanism is closed.
