| 摘 要： | 介绍了D型石墨的发展历程,分析了激冷铸铁凸轮轴D型石墨形成条件,并通过试验的方法来寻找和确定影响北京现代轿车α系列激冷铸铁凸轮轴轴颈出现D型石墨的因素.在生产激冷铸铁凸轮轴过程中,要将D型石墨控制在一定范围内,否则会降低凸轮轴的强度和机械加工性能.通过控制合金元素、铁液的过热保温时间、过热温度、浇注时间、浇注速度、铁液的孕育处理、孕育剂的选择、冷铁的尺寸等因素,来控制凸轮轴的轴颈处的D型石墨在10%以内.

| Abstract: | This article describes the course of development of the D-type graphite and analyzes the condition of forming D-type graphite on the chilled iron camshaft.A test was conducted to identify and determine the factors of forming type D graphite in the process of chilling production of cast iron camshaft of the Beijing Hyundai sedan α series of chilled iron camshaft journal.The D-type graphite should be controlled within a certain range,otherwise it will reduce the strength and machining properties of the camshaft.By controlling alloying elements,molten iron overheat duration,superheating temperature,pouring time,pouring speed,molten iron inoculating treatment,inoculant choice,chilled-iron dimensions and so on,the amount of D-type graphite can be reduced,and controlled within 10% in the camshaft journal. |
