Manufacture of the Wear Corrosion Resistance High-Cr Cast Iron Impeller
A wear corrosion resistance high-Cr cast iron was introduced in this paper, and the cast forming technique of 150ZGB impeller was also presented. The produced impellers, according to the technique, met the quality demands, such as no crack, surface smoothness, and high hardness. The service life of the impellers, in phosphoric acid slurry condition, were 4 to 6 times as long as that made from UB6 (0Cr20Ni25Mo5).
