摘要
研究了用连铸球铁棒材制备奥贝球铁汽车正时齿轮的生产工艺。结果表明，用含Mn达0．72％的球铁棒材，经合适的等温淬火处理后，能获得较理想的奥贝球铁组织和较高的综合力学性能。所生产的奥贝球铁齿轮满足设计要求，可用来代替传统的20CrMnTi钢，并带来明显的经济效益。
In this paper, the production techniques for making ADI autotruck timing gears by us-ing continuous casting ductile iron bars were studied. It is found that after proper austempering pro-cess, the ductile iron bars with manganese content up to 0. 72% can obtain more ideal microstructures and higher synthetic properties. The produced ADI gears are well satisfied with design requirements.They can be used to replace the original 20CrMnTi steel and has found wide application in industry
