    • A desulfurization apparatus which employs first and second separate independently movable spaced apart lances (10, 12), each lance having a single conduit (22) through which the desulfurization materials may flow from feed vessels (40, 42, 44, 46) into the molten iron in a ladle (16). First and second independently operable raising and lowering apparatus (28, 30) are provided, the first raising and lowering apparatus (28) being connected to the first lance (10), and the second raising and lowering apparatus (30) being connected to the second lance. Each of the first and second raising and lowering apparatus (28,30) is capable of moving the associated lance (10, 12) from between a raised position where the lower end of the associated lance is spaced above the surface of the molten iron in the ladle and a lowered position where the lower end of the associated lance is spaced within the ladle at a proper location for desulfurization of the molten iron. The first and second raising and lowering apparatus are spaced apart sufficiently so the reaction zones do not overlap even at maximum flow rate of desulfurization materials.
    • 一种脱硫装置,其采用第一和第二分离的独立可移动间隔开的喷枪(10,12),每个喷枪具有单个管道(22),脱硫材料可以通过该导管从进料容器(40,42,44,46)流入 钢包中的铁水(16)。 设置有第一和第二可独立操作的升降装置(28,30),所述第一升降装置(28)连接到所述第一喷枪(10),所述第二升降装置(30)连接到所述第一升降装置 第二枪 第一和第二升降装置(28,30)中的每一个能够将相关联的喷枪(10,12)从升高位置移动,其中相关联的喷枪的下端在铁水表面之间间隔开, 钢包和下降位置,其中相关联的喷枪的下端在钢包内在用于铁水脱硫的适当位置处间隔开。 第一和第二升降装置充分间隔开,因此即使在脱硫材料的最大流量下,反应区也不重叠。

    • A detecting magnetic coil is mounted adjacent the authenticity-determining magnetic coil of an electronic slug rejector to distinguish between authentic coins and any copper slugs which might cause the authenticity-determining coil to produce an output which closely simulates the output which that authenticity-determining coil produces in response to authentic coins. The signal from that detecting coil is used to control the accept/reject gate of that electronic slug rejector; and it will effect movement of that gate to "accept" position in the event it detects a non-cupreous object but it will not effect such movement of that gate in the event it detects a copper slug.
    • 检测电磁线圈安装在电子排料器的真实性确定的磁线圈附近,以区分真实的硬币和任何可能导致真实性确定线圈产生严重模拟输出的输出的铜芯块,该真实性确定线圈 响应正宗的硬币产生。 来自该检测线圈的信号用于控制该电子塞子排出器的接受/拒绝门; 并且在其检测到非铜对象的情况下将影响该门到“接受”位置的移动,但是如果它检测到铜块,则该门将不会影响该门的移动。
