    • A gas having high CO content evolved at reaction zone in a ferrosilicon-refining electric furnace is burned and deflected to wipe transversely on the top level of the charged raw materials with the aid of air introduced near electrodes through an air pipe. The burning of the gas is so controlled that a content of oxygen in the burned gas is within a range of 12-17% by volume by controlling a volume of the air to be introduced near electrodes as well as a volume of air invading into the furnace through a poking window and a gap between a shell of the furnace and a heat-shielding hood above the furnace. The CO-rich gas which has heretofore been exhausted in vain from the furnace can now be used to preheat the charged raw materials and prevents the furnace from blocking due to formation of crusts at the top level of the charged raw materials. The exhaust gas is now less noxious, has a higher temperature that can be used for driving a turbine of a generator. High heat efficiency, high quality of ferrosilicon, useful electric power and less blocking troubles can be obtained in a simple and economical way.
    • 在硅铁精炼电炉中在反应区放出的具有高CO含量的气体被燃烧并偏转以借助于通过空气管引入电极附近的空气横向擦拭带电原料的顶部水平。 气体的燃烧受到控制,通过控制在电极附近引入的空气的体积以及侵入到气体中的空气的体积,燃烧气体中的氧含量在12-17体积%的范围内 炉子通过捅窗和炉壳之间的间隙和炉上方的遮光罩。 迄今为止,已经从炉中排出的富含CO的气体现在可以用于预热加入的原料,并且防止由于在带电原料的顶层形成结壳而导致的炉堵塞。 废气现在较少有毒,具有可用于驱动发电机的涡轮机的较高温度。 以简单经济的方式可以获得高热效率,高质量的硅铁,有用的电力和较少的阻塞故障。

    • When a light guide of a sleeve is inserted into a through-hole, a positioning rib is mounted in the holding recess and the sleeve is positioned in the housing. When a transmitting optical module is mounted in a housing space, a positioning protrusion of the sleeve enters a positioning recess of the transmitting optical module and contacts a stepped surface of the transmitting optical module. Thus, the transmitting optical module and a transmitting sleeve are positioned so as to face each other with high precision, and thereby the light transmission efficiency can be increased.
    • 当套筒的光导被插入到通孔中时,定位肋安装在保持凹部中,并且套筒定位在壳体中。 当发送光学模块安装在容纳空间中时,套筒的定位突起进入发射光学模块的定位凹槽,并与发射光学模块的台阶表面相接触。 因此,发送光学模块和发送套筒被定位成高精度地彼此面对,从而可以提高光传输效率。
