When the nodular cast iron is produced, pig iron, scrap steel and other raw materials are first smelted into molten iron in an electric furnace or a cupola furnace, a magnesium alloy or other spheroidizing agent is added to spheroidize the graphite, a silicon iron or other inoculant is added to improve the graphite morphology and distribution, and finally the nodular cast iron is poured into a mold. The nodular cast iron has high strength, the tensile strength can reach more than 400 MPa, can bear large pressure and impact load, and has good corrosion resistance and wear resistance, and is widely applied in the fields of automobile manufacturing, mechanical manufacturing, construction and municipal engineering, such as automobile engine cylinder blocks, crankshafts and municipal water supply pipelines. During the processing of the nodular castings, the processed castings need to be cooled, and a large amount of fresh water resources needs to be continuously consumed during the cooling process.
