摘要： A process for manufacturing reduced iron agglomerates which comprises introducing starting agglomerates that comprise both an iron oxide-containing material and a carbonaceous reducing agent onto the hearth of a moving-bed heating furnace, and heating the agglomerates to reduce the iron oxide contained in the agglomerates, wherein the iron oxide-containing material contained in the starting agglomerates has a mean particle diameter of 4 to 23 μm and contains at least 18% of particles having diameters of 10 μm or less. By the use of such starting agglomerates, the process attains: an improvement in the yield of reduced iron agglomerates having large particle diameters; a reduction in the manufacturing time, said reduction leading to an enhancement in the productivity; and a remarkable reduction in the content of impurities such as sulfur in the reduced-iron agglomerates.

摘要： Iron production furnace equipment includes a melting reactor into which iron oxide-containing raw material and slag formers are added. A melter arrangement melts the iron oxide-containing raw material and transforms the melted raw material into liquid slag. A smelting reduction reactor is connected to the melting reactor by a slag transfer arrangement. The smelting reduction reactor includes a heater arrangement for heating the slag, a port for supplying a reductant for reducing the iron oxide in the slag into a liquid iron melt and produces a combustible gas mixture including at least one of CO and H2. A gas connection is provided between the smelting reduction reactor and the melter arrangement. The melter arrangement in turn comprises a combuster combusting the gas mixture for purpose of melting the raw material.

摘要： Exemplary embodiments of the invention relate to a compressive rod assembly for applying force to a refractory vessel positioned within an outer metal casing. The assembly includes a rigid elongated rod having first and second opposed ends, a threaded bolt adjacent to the first opposed end of the elongated rod, and a compressive structure positioned operationally between the elongated rod and the bolt. Compressive force applied by the bolt to the elongated rod passes through the compressive structure which allows limited longitudinal movements of the elongated rod to be accommodated by the compressive structure without requiring corresponding longitudinal movements of the bolt. Exemplary embodiments also relate to rod structure forming a component of the assembly, and to a metal containment structure having a vessel supported and compressed by at least one such assembly.

摘要： Provided herein are materials that can achieve up to 14% hydrogen absorption by weight in ambient conditions, which is a marked improvement over the hydrogen absorption values found in the prior art. Further provided are experimental conditions necessary to produce these materials. In order to produce the hydrogen storage material, a transition metal (or Lithium) is vaporized in a pi bond gas in conditions that permit only a few bonding collisions to occur between the vaporized transition metal atoms and pi bond gas molecules before the resulting bonded material is collected.
