    摘要： Crushed flux lime to be used in a BOF converter is processed to minimize waste dust, obviate environmental complications caused by high pH in waste water, and to utilize a very high percentage of the original crushed lime for useful products. The crushed flux lime is screened to provide a fine grain fraction and a modified flux lime fraction. Only a small percentage of the modified flux lime fraction is dust which may be removed in a dust collection system, and the modified flux lime fraction is then passed to the BOF converter. The fine grain fraction is made into a highly fluidized lime of very small dimensions by pulverizing it further in the presence of a fluidizing agent.

    摘要： A molten bath-based process for direct smelting metalliferous material and producing molten metal in a direct smelting vessel that contains a molten bath that has a metal layer that is at least 900 mm deep. The process includes selecting operating parameters of the process so that feed material (solid material and carrier gas) is injected from above the metal layer into the metal layer via at least one solids injection lance with sufficient momentum to penetrate to a depth of at least 100 mm below a nominal quiescent surface of the metal layer to cause upward movement of molten material and gas from the metal layer.

    摘要： A molten metal treatment lance includes a refractory having at least one channel extending through the refractory. A first tubular member having two open ends is located in the channel of the refractory. The first tubular member has a side wall having an inner surface and an outer surface. A second tubular member having an open end and a closed end is positioned in the first tubular member. The second tubular member has a side wall having an inner surface, an outer surface and at least one opening extending from the inner surface of the side wall of the second tubular member to the outer surface of the side wall of the second tubular member. The second tubular member is positioned in the first tubular member so as to form a space between the inner surface of the side wall of the first tubular member and the outer surface of the side wall of the second tubular member.
