Critical Content of MgO in Spheroidisers Original Research Article

Magnesium oxide in spheroidiser is harmful to the production of ductile iron for decreasing active magnesium content. To obtain quality ductile iron, the effects of magnesium oxide content in spheroidisers on spheroidising treatment, microstrucure and properties of ductile iron were researched, and the critical magnesium oxide in spheroidisers was determined.
