本发明涉及取向硅钢高温连续退火炉领域，尤其涉及一种取向硅钢高温连续退火炉隔离装置，包括安装在炉壳上的隔离炉门及设置在隔离炉门四周的密封井；隔离炉门顶部两侧安装有水冷却装置；水冷却装置上部设有隔离炉门动力牵引装置；密封井包括固定密封井和伸缩密封井，伸缩密封井位于固定密封井内部并与固定密封井滑动连接，伸缩密封井与固定密封井端部连接处设有密封装置。本发明可以确保隔离炉门升降过程中实现无缝全密封状态，提高密封效果，且采用伸缩密封井实际降低了密封井的高度，间接降低了水冷却装置连接管道上升至最高点的净空标高，与传统固定式密封井高度相比可以降低高度50％～80％，从而降低厂房净空标高，节省厂房基建投资。

本发明公开了一种硅钢冷轧吹扫辊，涉及硅钢加工设备领域，包括安装架、上轧辊和下轧辊、下调节机构、上调节机构以及吹扫机构；所述下调节机构包括调节支撑底板、楔形插块以及调节油缸；所述上调节机构包括顶升油缸、顶升杠杆和顶升连杆；所述吹扫机构包括吹扫连接座、吹扫管道和吹扫排管。本发明通过在上轧辊和下轧辊的出料端安装吹扫机构能够便于对出料的钢带表面进行吹扫清洁，能够有效提升钢带成品的表面质量；由于下轧辊在轧制过程中承受的重量较大，通过调节油缸带动下轧辊两侧的楔形插块来回移动的方式对下轧辊的高度进行微调，能够保证下轧辊在轧制过程中整体的稳定可靠性。

采用XRD物相分析、金相组织观察及TEM精细组织分析研究了奥氏体组织结构状态对Fe-0.88C-1.35Si-1.03Cr-0.43Mn钢中温等温相变鼻温和孕育期的影响,以及不同温度奥氏体化后240℃等温20 min试样的组织结构特征。试验发现,随着奥氏体化温度的升高,中温等温开始转变的鼻温移向更低温度并且相变孕育期缩短;不同温度奥氏体化后同为240℃等温20 min处理,虽然均形成由贝氏体铁素体亚条平行排列构成的束状贝氏体组织,但贝氏体组织的精细结构状态不同,突出的差别在于对应低温奥氏体化贝氏体亚条端部边界具有凸起结构,而对应高温奥氏体化贝氏体亚条端部边界较为平齐且呈现楔形结构。不能简单地以马氏体切变机制认识试验钢中贝氏体组织的形成。 The influence of austenitization temperature on the incubation period and the bainitic phase transformation behaviour in high-carbon silicon steel has been investigated using X-ray diffraction(XRD), optical microscopy and transmission electron microscopy(TEM).
