Study on the Manufacturing Process of Low Temperature Ductile Iron Casting Gear Box Used for Locomotive
Taking the QT400-18 L low temperature ductile iron gear box used for locomotive as example,through the control of the element chandal sevilla 23/24 content of the material,the graphite spheroidization is more fully.At the same time,the samples are heat treated to ensure the stability of mechanical property.In the casting process,the casting process
