通过进行连铸结晶器插钢带试验，研究了钢水过热度、铸坯拉速、钢带尺寸等对钢带插入速度的影响。结果表明，板坯合理的拉速为1．2～1．4m／mi.，钢水最佳过热度为28-31℃，钢带插入速度髓铸坯拉速的增大而增大。当插入比接近1％时，插... 详细信息

通过进行连铸结晶器插钢带试验，研究了钢水过热度、铸坯拉速、钢带尺寸等对钢带插入速度的影响。结果表明，板坯合理的拉速为1．2～1．4m／mi.，钢水最佳过热度为28-31℃，钢带插入速度髓铸坯拉速的增大而增大。当插入比接近1％时，插入速度随着钢带尺寸的逐渐增大而减小。金相观察发现，该技术使连铸坯中心等轴晶区扩大到截面的45％～55％，在很大程度上消除了中心偏析，提高了中心组织的致密度，显著改善了连铸坯的组织结构，减少了轴向化学不均质性，提高了钢坯品质，同时连铸机拉速提高了30％～35％。

本文报导首次观察到在光控取向材料表面上液晶分子预倾角与紫外光非单调曝光的关系。我们发现这种在加氟聚乙烯基肉桂酸(PVCN-F)表面预倾角与曝光的关系是非单调性的,而在无氟PVCN时显示的关系是单调递减的。这些和PVCN-F和PVCN表面的入射光偏光性变化有关系。实验结果表明表面偏光性和入射光变化对于光控取向材料的预倾角产生在机理上起着很重要的作用。
