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.
