针对硅钢连续退火机组的主要能源介质消耗现状,对现有生产工艺和设备研究采取机组循环用水、增加清洗段漂洗级数等措施可节约大概27 m3/h的过滤水量,并可减少78%的弱碱处理量;将炉子烟气换热系统增加一级余热回收,每年回收的余热相当于583 t标煤消耗,可节约蒸汽5 368 t。 The present situation of energy consumption for silicon steel annealing line is analyzed in this paper.In existing process and equipment conditions,increasing the number of cleaning series will lead to a saving of about 27 m3/h of filter water and reduce 78 % of weak base processing volume.For the flue gas heat-exchange system,adding a waste heat recovery device will recover waste heat equivalent to 583 tons of standard coal per year,corresponding to a saving of steam 5 368 t per year. 

广泛应用于电子电力行业的取向硅钢材料的磁性能与其晶体取向密切关联，对取向硅钢晶体衍射花样的研究非常重要.采用理论计算的方式研究了取向硅钢的晶体衍射花样特征，并绘制了取向硅钢的高斯织构理论极图、理论单晶透射电子衍射斑点花样和理论电子背散射衍射(Electron backscatter diffraction, EBSD)菊池花样.取向硅钢理论单晶衍射花样不仅可以为以后标定样品实测晶体衍射花样提供一种简单快捷的方法，也可以为样品检测提供一种标准.这种研究方法不仅限于取向硅钢，也被期待应用于其他材料晶体衍射花样研究. The magnetic properties of oriented silicon steels which are widely used in electronic and power industries are closely related to their crystal orientations, so it is very important to study the crystal diffraction patterns of oriented silicon steels. The characteristics of crystal diffraction patterns of oriented silicon steels are studied by means of theoretical calculation. The theoretical pole figures, theoretical single crystal transmitted electron diffraction patterns and theoretical elec...

结合实际生产0.4%Si无取向硅钢，统计了不含Sn和0.025%Sn无取向硅钢的磁性能变化，利用金相显微镜、X射线衍射仪观察分析不同成分下试样的显微组织和微观织构。试验结果表明：Sn元素可以显著降低无取向硅钢的晶粒尺寸，0.025%Sn试样的平均晶粒尺寸比不含Sn减小28.4%;加入Sn元素后抑制了无取向硅钢中不利于磁性能的{111}面织构组分强度，提高了对磁性能有利的{100}面织构组分强度，0.025%Sn与不含Sn相比磁感均值从1.756 T提升至1.768 T,铁损均值从5.476 W/kg降低至5.204 W/kg,明显改善了无取向硅钢磁性能。 In this paper combined with the actual production of 0.4% Si non oriented silicon steel, the magnetic properties of non oriented silicon steel without Sn and 0.025% Sn were counted. The microstructure and microtexture of samples with different compositions were observed and analyzed by metallographic microscope and X-ray diffraction. The results show that: Sn can significantly reduce the grain size of non oriented silicon steel, and the average grain size of 0.025% Sn sample is 28.4% smaller tha...
