摘要： Provided is a blow-pipe structure for a blast furnace facility configured so as to be capable of suppressing slag adhesion by using a simple structure, even if pulverized coal with an unadjusted softening temperature is used. The blow-pipe structure is attached to a tuyere for a blast furnace main body that produces pig iron from iron ore, said blow-pipe structure injecting auxiliary fuel pulverized coal together with hot air, and slag from the pulverized coal containing a component that is melted by the hot air and/or heat from combustion of the pulverized coal. A resisting element that increases flowpath resistance on the pipe inside wall surface side and concentrates the flows of the hot air and the pulverized coal to the flowpath axis center is provided on the downstream side of an injection lance that inserts pulverized coal into the blow pipe.

摘要： A method and an apparatus for the production and the melting of liquid pig iron or of liquid steel intermediate products in a melt-down gasifier, with the introduction of oxygen-containing gas streams through oxygen nozzles into the solid bed. At least one oxygen nozzle has a single gas supply and introduces at least two gas streams. Using plural gas streams from a nozzle reduces the risk of fluidization of the solid bed because the number of gas raceways in materials in the gasifier is increased.

摘要： A method and a plant for the production of pig iron or liquid steel semi-finished products are shown, metal oxide-containing batch materials and, if appropriate, aggregates being at least partially reduced in a reduction zone by a reduction gas, subsequently being introduced into a smelting zone and being smelted along with the supply of carbon carriers and oxygen-containing gas and along with the formation of the reduction gas. The reduction gas formed in the smelting zone is supplied to the reduction zone, reacted there and drawn off as export gas, CO2 is separated from the export gas, and a product gas is formed which is utilized for the introduction of pulverulent carbon carriers into the smelting zone.

摘要： The present invention proposes a pulverized coal injection lance (10) for feeding pulverized coal from a rear end of the lance (10) to a front end (11) of the lance (10). The lance (10) comprises an outer pipe (12) for conveying combustive gas, and an inner pipe (14), coaxially arranged within the outer pipe (12), for conveying pulverized coal. The inner pipe (14) forms a separation wall for separating the pulverized coal from the combustive gas. The separation wall is at least partially discontinued in a region near the front end (11) of the lance (10), thereby forming a mixing region (16) within the pulverized coal injection lance (10). According to an important aspect of the invention, the outer pipe (12) and the inner pipe (14) have substantially the same length and wherein the inner pipe (14) comprises at least one lateral opening (18, 20) for allowing pulverized coal and combustive gas to come into contact within the pulverized coal injection lance (10) near the front end (11).

摘要： A method for testing micropower short-wave frequency-modulation digital radio includes the steps of providing at each test station on a production line with a steel cage that is adapted to accommodate a transmitter and a corresponding receiver for test; and providing between two steel cages located at two adjacent test stations with an interference generator that transmits signal-free carriers having the same frequency as that of electric waves transmitted from the transmitter to be tested. Electric waves outward radiated from a steel cage are first attenuated by the steel cage, then destructed by electric waves from the interference generator, and then attenuated again by a steel cage at another test station. Since the attenuated signal-free carriers are not decoded at the receiver in any other steel cage, radio tests could be simultaneously conducted at two adjacent test stations without being mutually interfered.
摘要翻译：一种用于测试微功率短波频率调制数字无线电的方法包括以下步骤：在生产线上的每个测试站处提供适于容纳发射机的钢制笼和用于测试的相应接收机; 并且在位于两个相邻测试站的两个钢笼之间提供一个干扰发生器，该干扰发生器传输与从待测发射机发射的电波频率相同的频率的无信号载波。从钢笼向外辐射的电波首先被钢笼衰减，然后被来自干扰发生器的电波破坏，然后再次被另一个试验台的钢笼衰减。由于衰减的无信号载波在任何其他钢笼中的接收机处不被解码，所以无线电测试可以在两个相邻测试站同时进行，而不会相互干扰。

摘要： A method of melting and refining metals by high-temperature impinging combustion products generated by a single or multiple oxy-fuel or fuel/oxygen/air combustors that direct a flame towards a predetermined area of scrap to be melted. Once a portion of charged scrap contacted by the flame or flames is melted, an injection of solid carbonaceous fuel is initiated, preferably through a combustion tunnel of at least one of the combustors. High velocity oxygen is directed, simultaneously with carbonaceous material, through at least one dedicated nozzle toward injected solid carbonaceous fuel to mix with this fuel and to generate CO, which is capable of forming foamy slag. Optionally, a supersonic stream of multiple streams of additional oxygen is directed toward the iron--carbon melt to initiate rapid melt refining.
