High-spheroidization-rate and high-elongation nodular cast iron cycloid hydraulic motor rear cover casting casting process

The invention relates to the technical field of casting of motor rear cover castings, in particular to a casting process of a high-spheroidization-rate and high-elongation nodular cast iron cycloid hydraulic motor rear cover casting. Comprising a collection module, a smelting module, a pouring system, a processing module and a detection module, the pouring system is used for calculating impurity content data of a mold melt and comparing the impurity content data with content data set by a pouring unit, and the pouring system controls the smelting module, the processing module and the detection module; the pouring system comprises a pouring unit, a scanning unit, a calculation unit, a casting unit and a melt unit. The casting system is arranged, the volumes of different casting molds are calculated, meanwhile, the control unit is arranged, the total amount of the needed melt can be determined according to the overall volume of the molds, meanwhile, the volume of the molds is calculated, the casting speed is se
