ABSTRACT:
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.
