船用推进系统轴承盖的铸造工艺

Marine propulsion system for bearing cover of casting

轴承盖是船用推进系统的关键部件,安装在轮船后部与支柱相连,材料为EN-GJS-500-7U,需要进行材料性能、尺寸、UT(全部)、MT、PT等检验。在冷硬呋喃树脂砂铸造生产过程中,遵循型腔快速充型和铸件顺序凝固的原则,利用MAGMA软件模拟,结合现场生产经验,通过温度场的分析,设计铸造工艺,生产出满足顾客需求的优质合格铸件。

The bearing cap installed on the ship back and connected to the backbone is the key component of the propulsion system.The material is EN-GJS-500-7U.Tt needs inspection of the material performance,size,UT,MT,PT an so on.To produce high quality castings which meet customer demand,we design casting process using the MAGMA simulation software combining with the production experiences,following the rapid flling and proportional solidifcation and analyzing temperature feld in cold-setting resin furan sand casting production process.
