The invention provides an intelligent molten iron conveying system. The system comprises a haulage motor body, a molten iron conveying vehicle body, a vehicle-mounted control system and a ground control system, wherein the vehicle-mounted control system is used for controlling motions of the haulage motor body and the molten iron conveying vehicle body according to a control instruction, the ground control system is used for collecting external environment information and controlling a ground advancing line of the haulage motor body and the molten iron conveying vehicle body according to the control instruction, and a centralized control platform is used for sending the control instruction to the vehicle-mounted control system and the ground control system. Automatic interaction of information and the control instruction is performed through the centralized control platform, a molten iron transporting vehicle achieves unmanned and organization scheduling intelligence in the whole molten iron transporting working process from a blast furnace casting field to a steel making transit station, the haulage motor operation efficiency is improved, the iron molten temperature drop is lowered, the road and haulage motor operation safety is improved, equipment damage and accidents caused by faults such as worker operation and judgment are completely eradicated, the operation risk is lowered, and personal safety of workers is ensured.
