| 摘要:为提高企业制浆磨片的生产效率及降低生产成本，本研究在单浇工艺的基础上提出叠浇工艺，通过Solidworks建模软件与Anycasting铸造仿真软件对单浇与叠浇磨片的成型和凝固过程进行了仿真模拟，并利用现代仪器分析技术，在模拟和实验两方面对比与优化铸造磨片。结果表明，叠浇与单浇工艺在铸造模拟过程中均能使磨片平稳地充型、凝固，且叠浇工艺的应用将会降低覆膜砂与钢水的使用成本，提高生产效率。2种磨片在保持基体组织均匀的同时，叠浇磨片析出了更多片状或条状的M7C3型碳化物，以及少量环状氧化物类、氧化铝类及硫化物类夹杂物，会对磨片性能产生一定影响，导致其齿尖到齿根的硬度平均值为32.8 HRC，而单浇磨片的硬度平均值为45.0 HRC。 |
| Abstract:In order to improve the production efficiency and reduce production costs of refiner filling for pulping in enterprises， this study proposed a stacked casting process based on the single casting process. The forming and solidification processes of single casting and stacked casting refiner fillings were simulated using Solidworks modeling software and Anycasting simulation software. The modern instrument analysis technologies were used to compare and optimize the casting refiner filling in both simulation and experimental aspects. The results indicated that the refiner fillings could be smoothly filled and solidified under both stacked casting and single casting process during the casting simulation process. The application of stacked casting process would reduce the cost of coated sand and molten steel， and improve production efficiency. While maintaining a uniform matrix structure， stacked refiner filling produced more sheet-like or strip-shaped M7C3 carbides and a small amount of cyclic oxide， alumina， and sulfide inclusions， which had a certain impact on the performance. As a result， the average hardness from the tip to the root of the tooth of stacked casting refiner filling was 32.8 HRC， while the average hardness of the single casting refiner filling was 45.0 HRC. |
