    • PURPOSE: An electrode elevating apparatus of an electric furnace is provided to adjust combination and length of an electrode easily via an electrode settlement in a short time and to prevent an accident. CONSTITUTION: Length of an electrode is adjusted when the lower end of an electrode in use in an electronic furnace body(10) is abraded. For the adjustment of the length, the electrode is placed on an electrode strut(190) and an electrode holder is unclamped by a clamp lever. The electrode rod is lifted up with an arm of a master. After certain height ascent of the electrode holder, the electrode holder is clamped with the electrode by a clamp. Thereby, the length of the electrode is adjusted.
    • 目的:提供电炉的电极升降装置,以便在短时间内通过电极沉降来容易地调节电极的组合和长度,并防止事故发生。 构成:当电子炉体(10)中使用的电极的下端被磨损时,调节电极的长度。 为了调整长度,电极被放置在电极支柱(190)上,并且电极支架被夹紧杆松开。 电极杆用主臂的臂抬起。 在电极夹持器的一定高度上升之后,电极夹具通过夹具与电极夹紧。 由此,调整电极的长度。

    • PURPOSE: A holder device with an electrode breakage detecting function of an electric furnace is provided to effectively prevent the erosion of facilities due to any electric spark between electrodes and other components. CONSTITUTION: A guide rail(12) extending up and down is formed at one side of an arm(10). A wheel(28) constructed to move along the guide rail is mount at one side of a holder(20) supporting an electrode(120). Electric contact points(14) corresponding to each other are formed both on the arm and the holder. An elastic coil spring(18) is installed between the arm and the holder to provide an elastic repulsive force, which is larger than the weight of a holder in the case of the breakage of the electrode, toward a direction capable of raising the holder.
    • 目的:提供具有电炉断电检测功能的支架装置,有效防止电极和其他部件之间电火花引起的设备腐蚀。 构成:在臂(10)的一侧形成上下延伸的导轨(12)。 构造成沿着导轨移动的轮(28)安装在支撑电极(120)的保持器(20)的一侧。 彼此对应的电接触点(14)同时形成在臂和支架上。 弹性螺旋弹簧(18)安装在臂和保持器之间以提供弹性斥力,该弹性斥力大于在电极断裂的情况下的保持器的重量朝向能够抬高保持器的方向。
