采用高通量场发射扫描电镜结合图像批处理技术以及全自动显微维氏硬度分析技术对2种不同成分(W1和W2)的火车车轮轮辋踏面附近较大范围内的显微组织和硬度进行了原位统计分布表征,探究了轮辋靠近踏面的关键区域铁素体面积分数和珠光体片层间距的分布规律.通过大尺度原位统计分布表征结果可以发现,2种车轮铁素体面积分数自踏面往里均呈现逐渐增加的趋势,但固溶强化元素Si和沉淀强化元素V的含量差异以及W2车轮所采用更为精细的阶梯式淬火工艺对车轮的微观组织和硬度的定量分布有较大影响.固溶强化和沉淀强化元素含量较少的W1车轮的铁

高炉炼铁过程通过增煤减焦实现节能减排目标,针对人工操作模式存在主观性、粗糙性和滞后性难以实现增煤减焦的问题,采用上下协同优化控制方法,一方面通过上部提前匹配减焦方式维持高温区热平衡,另一方面通过富氧鼓风保证下部喷入煤粉的高消化率,使煤粉在风口回旋区充分燃烧.进而从控制角度解析描述增煤减焦过程,将铁水温度的稳定控制问题转换为风口回旋区温度的稳定控制问题,提出增煤减焦协同优化控制策略及风口回旋区温度对焦炭和煤粉不同滞后时间的稳定控制策略.首先,建立煤粉燃烧系统的T-S模糊模型,将辨识得到的喷煤最大时延区间进行
利用离散单元法研究烧结矿竖冷炉在排料过程中颗粒运动的流型和速度分布.模拟结果表明,烧结矿颗粒在下移过程中,运动流型依次呈“一”→“S”→“V”转变;在竖冷炉腔内的大部分区域,烧结矿颗粒保持整体流动;在中心风帽上方的局部区域(宽480 mm,高1280 mm),运动流型会随排料的进行在整体流和漏斗流之间转变.烧结矿颗粒速度分布表明,在中心风帽上方会形成更大区域的(宽960 mm,高3200～3840 mm)梯形缓慢流动区.缓慢流动区内颗粒下移速度较小,冷却后的颗粒不能及时排出炉外,不利于气固换热效率的提高.
