| Abstract: | To keep pace with power increasing of diesel engines a trial to adopt vermicular iron for production of LR4108 model cylinder block was carried out. The ferrosilicon-rare earth was used as vermicularizing alloy, and ferrosilicon-rare earth-magnesium alloy was used to stir the molten iron. Mechanical properties of the material for the trial cylinder block have met requirements of RuT300 grade of vermicular iron. The vermicular iron cylinder block has passed successfully through the machining process flow used for machining the gray iron blocks, and passed through the compactness test. |
