Processing technology of high-performance nodular cast iron pipe and product thereof

The invention relates to the technical field of nodular cast iron pipe processing, and particularly discloses a processing technology of a high-performance nodular cast iron pipe and a product thereof, and the processing technology comprises the following steps: carrying out thermal refining on molten metal and scrap steel according to a specific proportion, and then carrying out primary inoculation treatment and spheroidizing treatment. A proper nucleating agent is added in the casting process, and then a good metallographic structure is ensured through centrifugal casting and a specific cooling process; and finally, the pipe fitting achieves ideal mechanical properties and metallographic structures through trolley type annealing heat treatment. The high-performance nodular cast iron pipe which is excellent in mechanical performance, good in corrosion resistance and easy and convenient to install can be produced through the technology, and the requirements of thin-wall cast pipes are met. 本发明涉及球墨铸铁管加工技术领域，具体
