text-align: center;"><img style="width: 677px !important; height: auto !important; visibility: visible !important;" src="http://www.555lc8.com/zb_users/upload/2020/01/20200123143140_25696.png" crossorigin="anonymous" data-src="http://www.555lc8.com/zb_users/upload/2020/01/20200123143140_25696.png" data-type="png" data-ratio="0.6666666666666666" _width="677px" data-fail="0"/></p><p style="white-space: normal; text-align: justify;"><span style="font-size: 15px;text-decoration: inherit;widows: 1;">这个修改是一个比较大的变化,这主要是在2000年之后到现在国内宽厚板生产线无论是数量还是装备水平均得到前所未有的快速提升,据笔者不完全统计这期间我国共建设了30多条宽厚板生产线,其中包括具有世界最宽且装备水平一流的多条生产线,从而也使厚板的产品质量得到大幅度的提升。这些现代化的先进生产线以宝钢5m厚板厂、鞍钢营口鲅鱼圈5.5m宽厚板厂(号称“世界轧机之王”)、沙钢5m宽厚板厂等较为典型。下表为我国2000年之后建设的5m以上的宽厚板生产线。</span></p><p style="white-space: normal;

&nbsp; 齿轮、凸轮副、滚动轴承、钢轨与轮箍、凿岩机活塞与钎尾的打击端部等,它们的接触面在滚动或滚动与滑动复合摩擦时,接触应力反复作用下引起的表面破坏现象称为“接触疲劳”。零件产生接触疲劳时,接触表面上产生许多针孔或痘状凹坑,称之为“麻点”或“点蚀”,有的凹坑很深,呈贝壳状。在刚开始出现少数麻点时仍可继续工作;随着时间延长,麻点剥落将不断增多和扩大,磨损加剧,将发生较大附加冲击力,噪声增大,甚至使零件折断,这就是接触疲劳现象。</span></section><section style="text-align: justify;line-height: 1.5em;"><span style="font-size: 16px;">&nbsp; &nbsp; 影响接触疲劳的主要因素如下:</span></section><section style="text-align: justify;line-height: 1.5em;"><span style="font-size: 16px;">&nbsp; &nbsp; 1)非金属夹杂物</span></section><section style="text-align: justify;line-height: 1.5em;"><span style="font-size: 16px;">&nbsp; &nbsp; 轴承钢中的非金属夹杂物有塑性的、脆性的和不变形(球状)的三种。其中塑性夹杂物对接触疲劳寿命的影响较小,球状夹杂物(即硅酸盐和铁锰酸盐)次之,危害最大的是脆性夹杂物(Al</span><span style="font-size: 12px;">2</span><span style="font-size: 16px;">O</span><span style="font-size: 12px;">3</span><span style="font-size: 16px;">、氮化物、硅酸盐和碳化物等)。因为它们无塑性、与基体间的弹性模量不同,容易在夹杂物和基体交界处引起高度应力集中,二者的膨胀系数差别对应力集中影响很大,从而成为影响疲劳寿命的重要因素。氧化物等夹杂膨胀系数小于基体,使金属界面产生残留拉应力,使得疲劳强度降低;硫化物膨胀系数大于基体,使金属界面产生残留压应力,不仅不降低疲劳强度反而有利于疲劳寿命。硫化物的有利作用还有可能是将氧化物包住,形成共生夹杂物。因此图9 所示为硅酸盐、氧化铝和硫化物对接触疲劳寿命的影响。&nbsp;
