- 摘要:
- 高锰钢衬板因其优异的耐磨性与冲击韧性，广泛应用于矿山、建材等重载工况。 其组织与性能高度依赖铸 造过程中的热传输与凝固行为。 综述了当前典型的高锰钢衬板铸造工艺，包括砂型铸造、金属型铸造、消失模铸造与V 法铸造，同时阐述了数值模拟技术(离散元法、有限元法)在高锰钢衬板研究中的应用。 探讨数值模拟在工艺优化中的辅 助作用，并分析各项铸造技术在成型机制、缺陷控制与组织调控方面的工艺特征与适用边界。 研究认为，将数值模拟技 术与合理的铸造工艺有效结合是提升衬板质量的关键路径。最后，指出了当前研究存在的问题，并对未来研究工作做出 了展望。High-manganese steel liner plates are widely utilized in heavy-duty service conditions such as mining and building material industries because of their exceptional wear resistance and impact toughness. The microstructure and mechanical properties of these materials are highly dependent on heat transfer and solidification behavior during the casting process. This paper reviews current mainstream casting processes for high-manganese steel liner plates, including sand casting, metal mold casting, lost foam casting, and V-process casting, while elaborating on the application of numerical simulation techniques (discrete element method, DEM; finite element method, FEM) in their research. This work explores the auxiliary role of numerical simulations in process optimization and analyses the technical characteristics and applicability boundaries of these casting methods in terms of solidification mechanisms, defect control, and microstructure regulation. The study concludes that the effective integration of numerical simulation technologies with rational casting processes is a critical pathway for enhancing liner plate quality. Finally, existing research limitations are identified, and perspectives for future investigations are provided.
