| titleOfInvention | Large-caliber nodular cast iron pipe die coating and preparation method and application thereof |
| abstract | The water-based centrifugal casting pipe die coating for the large-caliber nodular cast iron is prepared by selecting perlite and diatomite with different particle sizes as mixed refractory aggregates, matching with a composite suspending agent consisting of sodium bentonite and/or lithium bentonite and carboxylated rectorite, adding hollow microspheres and a common binder, and has excellent suspension stability, high-temperature crack resistance, low gas evolution property, permeability and hygroscopicity. Meanwhile, the invention also adjusts and optimizes the specific spraying process, coats the large-caliber nodular cast iron pipe die coating on the surface of the pipe die, and prepares the large-caliber nodular cast iron pipe after centrifugal casting, wherein the surface of the large-caliber nodular cast iron pipe has no surface defects such as air holes, bonded sand, shrinkage cavities and the like, and the surface quality is excellent. |
