酯硬化砂制造冲击座类铸钢件工艺研究

Process Study of Casting Steel Strikers by Ester-Hardened Sand

介绍了利用酯硬化水玻璃砂造型生产线制造一体式冲击座铸钢件的生产工艺研究及实践过程,简述了酯硬化水玻璃砂造型的工艺特点,论述了工艺研究及生产过程中如何保证产品质量,为防止气孔、缩孔、缩松、变形、砂眼等铸造缺陷所应采取的相应工艺措施。

In this paper,we introduce the process study and practice of casting steel integral strikers by ester-hardened silicate bonded sand moulding line in QRRS,with brief description of characteristics of ester-hardened silicate bonded sand moulding process and discussion of actions to be adopted to guarantee the quality of the product from casting defects,such as gas hole,shrinkage cavity,shrinkage porosity,deformation and sand hole,etc.
