The invention belongs to the field of hot working, and particularly discloses a design method suitable for a steel ingot ultra-high temperature hot delivery and heating process. According to the ultra-high temperature hot delivery and heating process design scheme provided through a numerical simulation method, when the thickness of a solidified shell layer at the bottom of a riser reaches 1/4 ofthe diameter of the bottom of the riser, a crown block lifts and loads a vehicle, and then steel ingots with dozzles and molds are transported to a forging shop; when ingot bodies are fully solidified, that is, when the thickness of the solidified shell at the bottom of the riser reaches half of the diameter of the bottom of the riser, the dozzles and the molds are removed from the steel ingots, and the steel ingots are loaded in a soaking pit furnace; and a temperature field when the steel ingots are demolded is used as an initial temperature field and the heating calculation is carried out in combination with the actual working conditions, the situation that the temperature difference between the inside and the outside of the steel ingots is less than 50 DEG C is used for determining that the steel ingots are heated uniformly and can be discharged form the furnace and forged. The design method can perform ultra-high temperature hot delivery on the steel ingots with the molds withoutaffecting the quality of the ingot bodies, realizes steel ingot demolding with liquid cores at the riser, improves the furnace loading temperature of the steel ingots, can fully utilize the residual heat of the steel ingots to improve the furnace turnover rate and reduce the burning loss of steel ingots, and effectively reduces fuel consumption.
