    • Disclosed herein is an apparatus for moving a snorkel in a chemical-heating-in-snorkel (CHIS or CAS-OB) refining facility. The CHIS(CAS-OB) refining facility includes a ladle having a plurality of porous plugs formed in the bottom thereof, a snorkel mounted to an arm vertically movably assembled to a column such that the lower end of the snorkel is deposited in molten steel contained in the ladle, and a blowing lance having a lower end extending into the snorkel, thereby increasing the temperature of the molten steel contained in the ladle. The snorkel moving apparatus includes a snorkel transfer car having wheels mounted at both right and left sides thereof such that the snorkel transfer car can be reciprocated along guides mounted at both right and lefts ends of the arm, the upper part of the snorkel being assembled to the snorkel transfer car, and at least one actuating member, having an operational end thereof connected to one end of the snorkel transfer car, for providing an external force necessary to move the snorkel transfer car forward and backward along the guides. According to the present invention, it is possible to selectively locate the snorkel above one porous plug whose opening state is good, thereby improving the facility operation rate and operation success rate. Therefore, it is possible to exclude the provision of an additional facility due to the poor opening state of the porous plug, thereby accomplishing the construction of an economical and efficient facility.
    • 本文公开了一种用于在化学加热吸管(CHIS或CAS-OB)精炼设备中移动通气管的设备。 CHIS(CAS-OB)精炼设备包括一个浇包,该浇包具有形成在其底部的多个多孔塞子,一个浮筒,安装在垂直可移动地组装到一个柱上的臂上,使得浮筒的下端沉积在钢水中 在钢包中,吹风枪具有延伸到通气管中的下端,从而提高钢包中所含钢水的温度。 呼吸管移动装置包括具有安装在其左右两侧的轮的通气管传送车,使得该呼吸管转移车可以沿着安装在臂的左右两端的引导件往复运动,该吸管的上部组装成 所述通气管传送车以及至少一个致动构件,其操作端连接到所述通气管传送车的一端,用于提供沿着所述引导件向前和向后移动所述通气管传送车所需的外力。 根据本发明,可以将打开状态良好的多孔塞上方的通气管选择性地定位,从而提高设备运转率和运转成功率。 因此,由于多孔塞的打开状态不良,可以排除设置附加设备,从而实现经济,高效的设备的构造。
