摘要： A direct current arc furnace is described with a cathodic electrode held in the center of the melting vessel and an anodic bottom electrode arrangement in the vicinity of an electrically conductive lower vessel from the vessel wall to the melt. The current supply and removal takes place on one side via leads to a rectifier power supply set up in spaced manner alongside the furnace. The lower vessel is connected in several quadrants with leads and in the vicinity of each quadrant a connecting plate is provided on the furnace wall. Close below the arc the power supplies are led in a horizontal plane to the furnace wall. The current intensity for the quadrants of the lower vessel adjacent to the rectifier power supplies is lower than that of the power supplies to the remaining quadrants. The spacings of the connecting plates for the quadrant areas can be unequal.

摘要： A process for producing pig iron is described, which contains a reducing shaft furnace 1 and a melting gasifier 2. The sponge iron produced from iron ores in the reducing shaft furnace is supplied to the melting gasifier and converted there into a pig iron melt. The gas produced in the melting gasifier is supplied directly via a line 4 as reducing gas to the reducing shaft furnace. The blast furnace gas passing out of the reducing shaft furnace, after traversing a CO.sub.2 scrubber 6, is at least partly heated in a heat exchanger to 200.degree. to 500.degree. C. and passed to a partial combustion plant 13 where, accompanied by the addition of oxygen, the gas is heated to the necessary reducing temperature.

摘要： There is disclosed a process of dezincifying the flow of material at the operation of a plant for the production of pig iron including a direct reduction shaft furnace and a meltdown gasifier.The crude reducing gas drawn off the meltdown gasifier is dedusted in two steps. In the first step zinc-poor coal dust is separated in a cyclone operated at a higher temperature, which is recycled into the meltdown gasifier. In the second step, upon cooling of the gas leaving the first cyclone, solid particles enriched with zinc are separated at a lower temperature. The dezincified reducing gas is fed to the direct reduction shaft furnace and the zinc-rich substances separated off the second cyclones are processed to a zinc concentrate.

摘要： A process is disclosed for treating the scrubbing water from the gas scrubbing process in an iron ore reduction plant. The scrubbing water is brought into direct contact with the gas in two gas scrubbers arranged in two successive scrubbing stages at the gas-side, is withdrawn from the gas scrubbers and is supplied again to the gas scrubbers after the solids it contains are separated, and after it is treated and cooled. The scrubbing water is separately withdrawn from the two scrubbing stages and only the scrubbing water from the first scrubbing stage is largely freed from solids in a thickener, then led into a warm water container. The scrubbing water from the second scrubbing stage is directly led into a return water container in which it releases carbon dioxide-rich flash gas led into the scrubbing water in the warm water container to enrich it with carbon dioxide. The scrubbing water from the warm water container is cooled in a heat exchanger, then fed back to the gas scrubbers of the two scrubbing stages together with the scrubbing water from the return water container. Moreover, part of the carbon dioxide-rich scrubbed gas or part of the carbon dioxide-rich water contained in the return water container may also be led into the warm water container to enrich the scrubbing water in the warm water container with carbon dioxide.

摘要： A process for cooling and cleaning hot gas containing ultrafine particles exhausted from a coal gasification plant, a blast furnace, or the like. The process utilizes a vertical saturation stage to enrich the gas stream with water vapor and thereby saturate the ultrafine particles contained in the gas stream. The resulting mixture of particles, exhaust gas, water vapor, and water is then directed through a packing prewasher and then an annular clearance washer for removal of the particles through the rapid condensation of the water vapor. The water and particles are separated from the gas stream in several stages throughout the process resulting in a final gas exhaust stream with a significantly lower ultrafine particle content.

摘要： A method is disclosed for pretreatment of a lumpy carbon carrier suitable for forming a fluidized bed and a solid bed used in the production of pig iron from iron ore. The ore is pre-reduced in at least one reduction plant and the thus produced iron sponge is subsequently final reduced and fused in a melt-down gasifier with the help of the lumpy carbon carrier and an oxygen-containing gas and is the carbon carrier is fed into the upper part and the oxygen-containing gas is fed into the lower part of the melt-down gasifier. These materials form, together with the iron sponge, a fluidized bed in the melt-down gasifier. Below the fluidized bed, a solid bed is formed consisting of said lumpy carbon carrier. A suitable carbon carrier may be formed by pretreating available coal by one of two methods. Lumpy coal tending to burst upon subjection to a shock-like thermal load is preheated for a minimum of one hour at a temperature of at least 300.degree. C. prior to being fed into the melt-down gasifier in order to diminish its bursting tendency and to reduce the thermal load to which it is subjected. Ground fine coal is blended with a binder and granulated into lumps.
