Example Embodiment
[0030] A method for preparing a spheroidizing agent for nodular cast iron with high spheroidization rate is prepared by the following manufacturing steps:
[0031] 1) Select raw materials according to the weight percentage of each element;
[0032] 2) Put the material obtained in 1) into the induction furnace for smelting;
[0033] 3) When the temperature reaches 1200℃~1300℃, it will be out of the furnace, and the alloy liquid will be poured into a sealed multi-layer ingot to cool to room temperature;
[0034] 4) 3) The cooled alloy liquid is crushed to the required particle size and processed into a finished product package.
