1、摘要二氧化铁是一种廉价的结构材料，由于耐受性强，容易受到冲击，对烟雾的敏感性低，切割和熔炼性能优良，在汽车、农业机械、机械和冶金机械等领域广泛使用。1.重要的应用价值和广泛的应用潜力：目前，几乎所有的二氧化二氮铸铁部件都直接用于冶炼或在机械加工后用于冶炼，而且为了满足具体的耐受性要求，常规处理包括增加以下成分：2.在二氧化二烯冶炼厂或在后热处理工艺中进行浸出。然而，前者大大增加了二氧化二铁的生产成本，后者消耗时间、能源并对环境造成严重污染。塑料加工大大提高了机械性能，因为它提高了生产效率和材料使用效率，而且延绳结构的完成率和同质性都很高。因此，通过塑料加工实现球面铸造的接近净的最终形成，是提高
2、球面铸造特性和扩大其应用范围的一个有效途径，该文章提到了一个更为常见的用于试验的熔化铁塑料工业，使用在高温压缩分析过程中，以及在石墨金属底层中，对塑料铸铁模拟的物理形式研究系统进行了弹性扭曲，从而改变了具有不同扭曲参数的粒子的规律性。在微经济学的演化过程中，我使用了最好的变形温度，而不是最佳的高温变化和滚动过程，我试着用剩余热塑料把球关在磨坊里。主要结果如下：利用物理模拟实验系统地研究了下一个不同变形参数中的超温变形行为。根据对实际力的压力曲线的分析，可以得出这样的结论：在球面铸造的热变形过程中，球面铸造的硬化和浸渍曲线上的峰值压力明显发生在球面铸造的硬化和浸渍曲线上，随球面铸造的硬化和浸渍曲
3、线而减少。温度以不同的电压率上升，而峰值电压首先上升，然后随着温度上升而下降。在温度范围为8451的条件下，可以将热滤到压缩变形中，这是一种重新压力。对球形铸铁变形样品下层组织的分析表明，球形铸铁呈现出变形过程中变形引起的相变现象。塑料铸铁代替他们的感应杏扁铁温度其150的新晃贡传统的第一变换，和温度引起的周围碎布总思想的存在主要失真石墨颗粒;杏扁诱导的温度变化，而不珠光体，由变化珠光体诱导面部形状，该球珠光体i后，通过HFC细铁髓其球形颗粒分布43个的变形试样，依赖于联合国规模仅为338米;对于许多其分割铁等，其直径的轴，由于只对参数的减小的平均的伊莫石墨1.16研究影响粒子变化规律的变形，
4、表明增加的温度：体积百分比，短p的石墨和石墨颗粒的形状因数（在）轴/长，显然是逐渐增大的间距石墨邻居的倾向;石墨的间隔时的应变速率的增加，而体积石墨的百分含量和形状系数的石墨粒子的不显著变化P来说略为降低。随着反应变量，相邻的石墨和形式因子p石墨粒子的间隔显示出明显的下降趋势，而按体积计石墨含量百分保持基本恒定。计算表明，当石墨演变球形到椭球的形式，石墨的形状变化可以减轻应力集中在基体中的石墨效果时，外部的应力的方向平行于长椭圆形的轴。在球形铁的热变形的方法中，石墨的塑性变形是由于基体的摩擦，使得在从所述主流可变电压的方向上延伸的石墨。 通过逐步逼近法获得QT450-10的最佳压力处理温度范围
5、。球墨铸铁的高温锻造和轧制过程是在这个温度范围内设计的。锻造过程中，球墨铸铁相变后奥氏体变形，细珠光体距离小于0.319 rri，与常规正火珠光体片层间距（0.46），m）相比，小锻造时为30.6o铸造样品伸长率降低了14，但拉伸强度从560 MPa降至905 MPa，增加了61.6，抗弯强度提高了61.2。当球墨铸铁坯料的压缩比达到8.83（89） （压缩量），板形保持良好，不发生破损，表明球墨铸铁具有良好的高温塑性;坯料中心的珠光体含量低于边缘，石墨由球形变化优化轧制参数后，与铸态球墨铸铁相比，坯料的抗拉强度提高了26.5，尤其是采样方式对平行方向的影响。 lel滚动高达34 J.板上出现
6、了各向异性。平行轧制方向（纵向）板坯的抗拉强度比垂直轧制方向（横向）高18.9，伸长率高13.3最后，本文进行了球墨铸铁球磨锻余残余热淬火实验，与常规淬火球墨铸铁磨球和铬铸铁磨球相比，锻造余热淬火球墨铸铁磨球马氏体结构由于继承变形奥氏体和完全精制的位错结构，磨边球的硬度值比传统淬火磨球高出5.3。锻造余热淬火磨球的冲击韧性是传统淬火磨球和高铬铸铁磨球的3倍。锻造余热淬火的磨球磨损率比传统淬火球墨铸铁低53.1，比含铬铸铁低51.1，摩擦系数0低于7.4。传统的淬火 - 球墨铸铁，比含铬铸铁低9.6关键词:球墨铸铁;塑性变形;石墨;形变诱导相变;锻造;轧制AbstractIron dioxide
