In the field of centrifugal casting, the material selection of the ash pipe and the slag discharge pipe is crucial, because these two pipes are subjected to the harsh environment of high temperatures, high pressures and corrosive gases for a long time. In order to ensure that the pipeline maintains excellent heat resistance, oxidation resistance, no peeling, no deformation and other characteristics in continuous work, high-quality heat-resistant steel materials must be selected.
Among the many heat-resistant steel materials, ZG40Cr25Ni20Si2 and ZG40Cr26Ni5Mn3Simore are highly regarded for their excellent properties. These two steels not only have strength and hardness at high temperatures, but also excellent resistance to oxidation and corrosion. In the centrifugal casting process, they can effectively resist the erosion of high-temperature molten materials, ensure that the inner wall of the pipe is smooth and flat, and avoid potential safety hazards caused by peeling or deformation of the material.
In addition, these two heat-resistant steels also have excellent thermal stability and thermal conductivity, which can maintain stable mechanical properties in high-temperature environments, effectively extending the service life of the ash pipe and the slag discharge pipe. At the same time, they have a small coefficient of thermal expansion and are able to maintain a low deformation rate in an operating environment with large temperature variations, thus ensuring the stable operation of the piping system.
In a word, ZG40Cr25Ni20Si2 and ZG40Cr26Ni5Mn3Simore, as heat-resistant steel materials for centrifugal casting ash pipes and slag discharge pipes, not only have excellent heat resistance, oxidation resistance, no peeling, no deformation and other characteristics, but also can maintain stable performance in harsh working environments, providing a strong guarantee for the sustainable development of centrifugal casting industry.
