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： Steel and pigment-grade TiO 2 with up to 99.99 % (TiO 2 + ZrO 2 ) are produced continuously by direct smelting ilmenite or titaniferous magnetite concentrates at ultra-high temperature. Both oxidic and metal phases are independently force circulated in fully backmixed melt circulation reactors. Close proximity to thermodynamic equilibrium permits liquidus composition melts to be contained within reactors with protective linings of unmelted shells comprised of oxycarbide of the solidus composition. The unmelted shells are maintained above the critical temperature of the ductile to brittle fracture transition by supercritical steam generation, whilst the endothermic heat is supplied by electrical conductive heating. Smelting reduction with natural gas or carbon with low sulphur content, followed by in-line continuous vacuum refining makes available a continuous feed of refined melt for further in-line processing at somewhat lower temperatures using known emerging technologies for titanium metal production.
摘要翻译：通过直接熔炼钛铁矿或含钛磁铁矿连续生产具有高达99.99％（TiO 2 + ZrO 2 2）的钢和颜料级TiO 2 专注于超高温。氧化物和金属相都独立地在完全反混合的熔体循环反应器中强制循环。靠近热力学平衡允许液态组合物熔体包含在反应器内，其中含有由固相组分的碳氧化物组成的未熔化壳的保护层。未熔化的壳体通过超临界蒸汽产生而保持在韧性的临界温度以上以进行脆性断裂转变，而吸热则由导电加热提供。使用天然气或低硫含量的碳进行熔炼还原，然后通过直列连续真空精炼，可以使用已知的钛金属生产新技术，在较低温度下连续进料精炼熔体进一步进行在线加工。

摘要： According to a method for utilising solid, optionally with the addition of iron ore, the recyclings are introduced into a melting cyclone (6), together with a reduction agent containing carbon, and oxygen, swirled and ignited. The recyclings are melted, the volatile heavy metals are reduced and evaporated and the iron oxides are reduced. The gases and melt are transferred together from the melting cyclone (6) to a directly connected separating vessel (7) in which the melt and gases are separated. The evaporated heavy metals are separated out of the gases outside of the separating vessel (7) and the melt is transferred into a metallurgical vessel (10) that is separate from the separating vessel (7). According to the invention, reduction agents which are fed into the metallurgical vessel (10) reduce the iron oxides of the melt to iron, whereby a slag that is low in iron is formed, while electrical energy is introduced to at least partially cover the heat loss and the reduction energy, in order to transform 100 % of the recyclings containing iron and heavy metals into useful products.

摘要： The invention relates to a method for producing liquid metal, in particular liquid pig iron (9) or liquid steel intermediates from metalliferous elements, in particular from partially or totally reduced sponge iron (3) in a melt-down gasifier (1). Carbon-containing material, consisting at least partially of coal fines (16) and coal dust (13), is fed with oxygen or an oxygen-containing gas to a bed (4) formed of said carbon-containing material. The metalliferous elements are melted down, forming a reduction gas, optionally after preliminary final reduction. After drying, the coal fines (16) and coal dust (13) that are to be used are mixed in the warm state with bitumen (20) and then briquetted in the cold state. The briquettes (25) thus produced are introduced to the melt-down gasifier (1) in the cold state and subjected to shock heating (1).

摘要： Smelting reduction apparatus for manufacturing a molten metal under the slag by adding a raw metal material, charcoal and a medium solvent to a furnace body having a rectangular horizontal section, and blowing oxygen and/or an oxygen enriched gas from a lower tuyere in the side wall of the furnace body into the slag and a method of operating the same are improved. An inert gas is blown through a botton tuyere provided in the vicinity of the center in the direction of shorter sides of a furnace bottom into the molten metal so as to secure a slag stirring operation in the vicinity of the center in the direction of the short sides. An inert gas is blown through a lowermost tuyere, which is provided in the side wall of the furnace body which is between a position lower than the lower tuyere and the interface between the slag and a molten metal so that the lowermost tuyere inclines at 0 DEG -45 DEG downward with respect to the horizontal plane, so as to stir the slag on the immediately upper side of the molten metal, increase the relative speed of the slag and molten metal and also increase the amount of heat transferred from the slag to the molten metal. The lower tuyere is provided laterally and perpendicularly to the long sides of the furnace body so as to incline at 15 DEG -45 DEG in the opposite direction of a raw material input port, so as to cause the slag to flow also in the direction of the long sides of the furnace body.
