Toughening Study on High Chromium Cast Iron Liner Plates of HZS Series Commercial Concrete Mixing Plant

Abstract:

Article Preview

Because of high wear resistance and low cost, high chromium cast iron liner plate is the most commonly used liner for HZS series concrete mixing station at present. However, in normal operation, the high-chromium cast iron liner produced by conventional casting process is easy to crack at its corners. We found that the cracking reasons of this type of liner plate are mainly the lower cast impact toughness, slightly higher hardness, and there has not gotten a good matching between the hard particles and the matrix organizations. Thus we used the secondary heat treatment to slightly reduce the hardness and increase the impact toughness of cast iron liner plate, which can improve the wear resistance and impact resistance of the liner material to extend the service life of these cast iron liners.
