Automobile part pouring material and pouring process
The invention discloses an automobile part pouring material and a pouring process, and belongs to the technical field of automobile parts, the automobile part pouring material comprises tabular corundum, quartz sand, ceramic powder, mullite, activated alumina micro powder, calcium aluminate, aluminum powder, a dispersant, a polycarboxylate superplasticizer, steel fiber, fly ash and water; after the components are uniformly mixed, sintered and prepared into the ceramic powder, the types and the number of particles in the casting material can be reduced, and the probability of layering of the casting material is reduced; the automobile part casting material has good mechanical properties, can be solidified at normal temperature, has small shrinkage rate even after high-temperature sintering, has good thermal shock resistance, and can be used in the machining process of automobile part metal material smelting and the like. Ultrasonic oscillation is adopted for assistance in the pouring solidification process of the automobile part pouring material, uniform dispersion of all components is facilitated, bubble discharging is facilitated, and the solidified pouring material is prevented from forming the air hole defect.
本发明公开了一种汽车零部件浇注材料及浇注工艺，属于汽车配件技术领域，组分包括板状刚玉、石英砂、陶瓷粉末、莫来石、活性氧化铝微粉、铝酸钙、铝粉、分散剂、聚羧酸减水剂、钢纤维、粉煤灰和水；将各组分混合均匀后烧结并制备成陶瓷粉末后，有助于减少浇注材料中的微粒种类以及数目，减少浇注材料分层的概率；本发明汽车零部件浇注材料具有较好的力学性能，能够在常温下凝固，即使高温烧结后收缩率也较小，并且具有较好的抗热震性，满足汽车零部件金属材料冶炼等加工过程的使用。汽车零部件浇注材料浇注凝固过程中采用超声波震荡进行辅助，有助于各组分分散均匀，并且有利于排出气泡，防止凝固后的浇注材料形成气孔缺陷。
