珠光铁矿灰铸铁配件
灰铸铁是一种铸铁.碳作为铸铁作为石墨{.的含量{.灰色的嘴是灰色的.具有良好的铸造，切割性能，良好的耐磨性，耐磨性.，用于制造架子，盒子，盒子，{4}}，{4} {4} . . .，{4} {. . .，{{4}应力浓度，因此灰色铸铁的强度，可塑性和韧性低于其他铸铁.的强度，韧性，但是它具有极好的振动阻尼，低凹口敏感性和高磨损抗性.
灰色铸铁具有高碳含量（2 . 7％〜4 . 0％），可以将其视为带有石墨的碳钢矩阵。根据不同灰色铸铁的基质组织，分为三类：铁基质灰铸铁；珍珠铁氧体基质灰色铸铁；珍珠基质灰色铸铁。
Pearl-ferrite gray cast iron is in the bead and ferrite mixed matrix, distributed with relatively thick graphite sheet, the strength and hardness of this cast iron is lower than the former, but still can meet the requirements of the general body, its casting, shock absorption are good, and easy to melt, is the most widely used gray cast iron.
灰色铸铁的不同微组织本质上是铸铁中的碳的不同形式.灰色铸铁中的碳由碳（Fe3c）组合（Fe3c）和石墨碳.组成，而当碳组合为0时，{5}} 8％，是灰色的铸铁；当组合碳小于0.8％时，它是铁氧体灰铸铁。当所有碳都在石墨中时，它是灰色铸铁。
The mechanical properties of gray cast iron are related to the organization of the matrix and the morphology of graphite. The sheet graphite in gray cast iron seriously separates the matrix, which is easy to cause stress concentration at the graphite tip Angle, so that the tensile strength, plasticity and toughness of gray cast iron are far lower than that of steel, but the compressive strength is equal to that of steel, and it is also the cast iron with the worst mechanical performance在常用的铸铁.同时，矩阵组织还对灰色铸铁的机械特性有一定的影响基质的灰色铸铁石墨片比灰色铸铁略大，灰色铸铁不如灰铸铁.，因此，珠子光体矩阵的灰色铸铁在行业中更常用.
