灰铸铁用V法涂料的研制与应用

Development and Application of V-Process Coating for Grey Cast Iron

介绍了一种灰铸铁件V法铸造用的新型涂料的原料和配方。测试了新型涂料的附着、悬浮、燃烧及高温爆裂性能。使用喷枪喷涂试制了铸件。结果表明，新研制的涂料具有更好的附着性能和悬浮性能，铸件表面光洁，无气泡，无裂纹，适用于喷涂作业，在实际生产应用中起到了提高铸造产品表面质量的作用。

Raw materials and components of a new type of coating used for grey iron castings produced by V-process were introduced. The adhesion, suspension, combustion performance and high temperature bursting performance of the new coating were measured. Spraying the coating to trial-produced castings with a spray gun was performed. The results show that the newly developed coating exhibited better adhesion and floatability, and can make casting surface finish, free of bubble and of crack, is suited to spraying operation, and may render the surface quality of cast products better in the actual production.
