| Abstract: | The production conditions, foundry method and melting process for mass production of nodu-lar iron couplers used for large trucks were introduced. By properly choosing chemical composition, raw materials, adopting proper nodularizing process and intensifying inoculation, as-cast mechanical proper-ties of castings have steady met specifications of China Standard QT400-18. |
