摘要： The hereinproposed method and furnace provide for preliminary building up of melt in a melting pot (10) of a rectangular shape in the horizontal section, delivery of an oxygen-containing gas (3) into the melt below its surface level through tuyeres (13) with nozzles (14) installed in the longer walls of the melting pot (10) creating two melt zones: an upper zone (9) loaded with solid carbon fuel (2) in an amount sufficient for providing a volumetric concentration of said fuel within 0.5 to 50% of the melt volume in said zone (9), wherein said concentration is maintained by subsequent concurrent loading of iron-bearing material (1) and solid carbon fuel (2), and a lower zone (8) consisting of a layer of slag (4) and a layer of ferrocarbon intermediate product (5) said layers being discharged separately through channels (17 and 18) made in the counterproposed short walls of the melting pot (10). The ratio of the horizontal section area of the melting pot (10) at the installation level therein of tuyeres (13) to the total area of the outlet holes of the nozzles (14) is 300-10000, while the distance (h) from the lower boundary of the product discharge channel (18) to the upper boundary of the slag discharge channel (17) is 0.3 to 0.75 the distance (H) from the lower boundary of the product discharge channel (18) to the installation level of the tuyeres (13).

摘要： An oxygen-fuel burner has a pipe 20 for fuel, for example pulverized coal carried in air, and two pipes 22 and 24 for oxygen. The burner is typically mounted horizontally above a burden to be heated. The oxygen pipes 22 and 24 have separate outlets disposed such that the flame is caused to curve towards the burden. The relative rates of supply of oxygen to the two passages are varied so that the flame is moved across at least part of the burden.

摘要： Coatings of metals, metal alloys, metal carbides, nitrides, borides, silicides and phosphides are provided. A precursor having organic ligands bonded to one or more metal atoms, such precursor having the element X also bonded directly or indirectly to the metal or metals, is pyrolyzed on a substrate surface to give a coating of M.sub.a X.sub.b. M represents a transition, lanthanide or actinide metal or tin, X represents C, N, B, Si, or P, and a and b represent the atomic proportions of M and X. The subscript b may be zero if an alloy or pure metal is to be prepared. The product M.sub.a X.sub.b can be prepared by relatively low temperature pyrolysis and the precursor can be used as a solution or a low melting solid.

摘要： A method for forming a directional and controlled suspension spray of a pulverous material and a reaction gas is intended for use in metallurgical processes and plants. In flash smelting, reaction gases are fed into a cylindrical vertical reaction chamber centrally through the top of the reaction chamber. The blasting in is via a specific blast-in member, into which the gases are usually directed horizontally for reasons of space use. This results in that the flow in the reaction chamber is asymmetrical. This disadvantage can be eliminated by means of a method according to the present invention. In the method according to the invention a pulverous material is directed into the reaction chamber mixed with a primary dispersion gas, a reaction gas directed into the reaction chamber in at least three separate, at least partly turbulent jets symmetrically around the flow of the pulverous material, and the reaction gas jets are caused in the reaction chamber to discharge into the flow of the pre-dispersed pulverous material in order to produce a turbulent but controlled suspension spray.
摘要翻译：用于形成粉末材料和反应气体的定向和控制的悬浮喷雾的方法旨在用于冶金工艺和植物中。在闪蒸熔炼中，反应气体通过反应室的顶部中心地进入圆柱形竖直反应室。爆破是通过特定的爆炸构件，由于空间使用，气体通常被水平地引导到其中。这导致反应室中的流动是不对称的。可以通过根据本发明的方法来消除这个缺点。在根据本发明的方法中，粉末材料被引导到与初级分散气体反应的反应室中，在至少三个分开的，至少部分湍流的喷射中引导到反应室中的反应气体围绕粉末材料的流动对称并且在反应室中引起反应气体射流以排出到预分散粉碎材料的流中，以便产生湍流但受控制的悬浮喷雾。

摘要： Pure ferro-alloy metals are isolated from fine-grained crude oxidic mineral products by reduction melting and subsequent anodic liberation of the iron. The reduction melting is performed in a plasma-heated furnace into which the fine-grained oxide material is blown together with carbon powder and circulating exhaust gas, extremely over-heated in a plasma generator, the quantity of carbon powder being dosed so that most of the alloy metal(s) is converted to carbides during the reduction. After electrolysis, the anode residue will consist primarily of alloy metal carbides from which the metal can be recovered by known methods.
