Maintainable crystallizaing wheel assembly structure

The invention discloses a maintainable crystallizaing wheel assembly structure. The maintainable crystallizaing wheel assembly structure comprises a wheel body and a casting groove. A metal filing piece small in heat conduction coefficient is embedded between the inner side wall of the casting groove and the outer side face of the wheel body. The wheel body is arranged between two rotating plates. Step faces matched with the inner circumferential wall of the wheel body and the inner circumferential wall of the metal filling piece are arranged on the inner sides of the outer edges of the rotating plates. The wheel body, the metal filling piece and the rotating plates are assembled into a detachable overall structure when the metal filling piece and the rotating plates are connected through bolts distributed along the inner portion of rings. The maintainable crystallizaing wheel assembly structure is simple and reliable in structure and convenient to assemble, the problems of blank cracks, interlayers and the like which are caused when the inner face and the outer face of the casting groove are cooled in an inconsistent mode are solved through the structural design of the maintainable crystallizaing wheel assembly structure itself, and the product quality can be effectively improved; meanwhile, by means of the structure, spraying area occupation of bolts in traditional design can be avoided so that the cooling efficiency can be improved, and the maintainable crystallizaing wheel assembly structure also has the advantage of being convenient to maintain.
