摘　　要：利用钒钛生铁开发了一种中铬抗磨铸铁。实验研究了化学成分中铬碳比、锰、硅以及热处理工艺对中铬抗磨白口铸铁组织和性能的影响,测试了该种铸铁的抗磨性。实验结果表明,所研制的中铬抗磨白口铸铁具有与高铬抗磨白口铸铁相当的组织和性能,但生产成本较高铬抗磨白口铸铁低,是一种经济实用的抗磨材料。Utilizing vanadium titanium pig iron is to develop a new wear resistant middle chromium cast iron. The effects of chemical compositions-chromium carbon ratio, manganese, silicon and the heat treatments on mechanical properties and microstructures are discussed. Meanwhile, the wear resistance of cast irons is evaluated. The experimental result indicates that the new developed cast iron is of satisfied wear resistance and with low cost, compared to high Chromium cast iron,therefore.
