Solidification characteristics of nodular iron castings

Austenite and graphite will precipitate in the solidification process of nodular iron casting. The crystallization of austenite will cause shrinkage, while the crystallization of graphite will cause expansion, that is, expansion will occur in addition to shrinkage in the solidification process, which makes the solidification process of nodular iron...

Initial graphitization expansion of nodular iron castings

In the solidification process of Hypereutectic nodular iron casting, when the temperature is lower than the graphite liquidus, the primary graphite ball will precipitate. In the growth process of primary graphite ball, due to the direct contact between graphite and molten iron, the diffusion of carbon atoms is much...

Nodular iron castings for small motor base

The nodular iron castings base plays the role of supporting and fixing the stator core in the motor. In the bearing end cover structure, the coordination between the base and the end cover plays the role of supporting the rotor and protecting the motor winding. There are many structural...
