| Abstract: |
| Based on the ordinary high chromium cast iron foundation, designed one kind of high alloy abrasion-resisting cast iron material which is used to make the lining iron of the screw grader. Analysis of the material microscopic organization and the performance indicate that the results are ideal. Through production experiment, we find that new high alloy abrasion-resisting cast iron lining irons of screw grader work nine times longer than ordinary lining irons. |
