The invention discloses an intelligent metering method for molten iron transported by a crown block. The method comprises the following steps of: installing an identity label and an identification device, recording tapping records, recording the moving track of a molten iron car, determining the hoisting and lowering actions of a crown block, automatically identifying and tracking an iron ladle, uploading metering data, defining a metering data model, defining and acquiring basic data of molten iron metering by a system, and automatically determining and calculating the molten iron metering data by the system. According to the invention, intelligent molten iron metering is adopted, there is no person in the whole metering process, information is seamlessly jointed between iron and steel and is completely transparent, each process from blast furnace iron receiving to steelmaking molten iron receiving and processing and molten iron circulation is controlled by a detail system in the whole process, manual intervention is completely avoided, metering data is fair, objective and real, intelligent molten iron metering and data seamless processing are achieved, iron and steel production collaboration is organically combined, and the production management and control level is improved.
