Description

[0002] ‌Austempered ductile iron is a ductile iron material that has been isothermally quenched and has excellent comprehensive mechanical properties. Through isothermal quenching, ductile iron can obtain a lower bainite matrix plus spheroidal graphite structure, which makes the casting have the comprehensive properties of high strength, high hardness and high toughness‌.

[0003] The isothermal quenching devices currently used still have the following problems:
