Heat treatment method of cast Iron platform Ductile iron

Heat treatment method of nodular graphite material of cast iron platform: the heat treatment of nodular cast iron plate includes annealing, normalizing, quenching and tempering, isothermal quenching and so on. Ductile iron plate is a new material plate developed in recent decades. Its mechanical properties are similar to those of medium carbon steel. Nodular cast iron is widely used because of its good casting properties. Ductile iron has a wide application prospect for castings with complex shape, high strength and toughness, such as internal combustion engine crankshaft, cast iron plate, bending plate, square box and so on.

 

This internal stress can deform, warp and change the size of the cast iron platform, and these defects cannot be eliminated even after processing. Therefore, the cast iron platform usually needs aging to eliminate the internal stress. Ductile iron plate is a new material plate developed in recent decades. Its mechanical properties are similar to those of medium carbon steel. Nodular cast iron is widely used because of its good casting properties.
