    • A reactor for iron making having an upper gas blowing nozzle, a lower gas blowing nozzle, and an iron scrap charging inlet. A vertical shaft is installed directly above the inlet at the top part of the reactor. A mechanism is provided in the lower end of the vertical shaft for controlling charging of the iron scrap to the reactor. A by-pass tube is connected between the top part of the reactor and a gas inlet in the vertical shaft directly above the mechanism for controlling the charging of iron scrap and permits exit of high temperature exhaust gases from the reactor and introduces the exhaust gases to flow through the iron scrap in the vertical shaft to pre-heat the same. Structure is provided in the by-pass tube for introducing oxygen gas or air into the high temperature exhaust gases to react therewith and generate further heat. The structure can comprise a nozzle. The mechanism for controlling charging of iron scrap can include a damper positioned immediately above the inlet in the top part of the reactor which is movable to open and close the vertical shaft together with a stopper positioned above the damper and movable to open and close the vertical shaft. Certain amounts of iron scrap can thereby be charged to the reactor by sequential openings and closings of the damper and the stopper.

    • Method of reactor iron making without using electric power in the reactor. Iron scrap and a solid non-petroleum carbonaceous material, i.e., powdery coal or coke, are continuously charged from above into molten iron in the reactor with a space over the molten iron. The carbonaceous material is charged by injecting it with a stream of nitrogen or air. Oxygen gas is simultaneously blown into molten iron below its surface so as to stir it and oxidize the carbonaceous material mainly to CO and blown into the space over the iron to oxidize the CO to CO.sub.2. The amount of oxygen is increased as the amount of molten iron increases. The iron scrap melts from the heat generated by the oxidation. The high temperature exhaust gas is used to preheat scrap to be charged. When the amount of molten iron reaches a predetermined level, it is tapped off until a lower predetermined level is reached. The above steps are repeated. Twin reactor iron making can use the method. Only part of the CO produced in one reactor is oxidized and high temperature exhaust gas is passed to the other reactor while oxygen is added thereto to oxidize the remainder and generate more heat. The heat of the gases and the additional heat of oxidation preheats scrap and carbonaceous material in that reactor.
    • 在反应器中不使用电力的反应堆制铁方法。 将铁废料和固体非石油碳质材料,即粉煤或焦炭从上面连续地装入反应器中的铁水中,铁水上方有一个空间。 通过用氮气或空气流注入含碳材料。 氧气同时吹入其表面下方的铁水中,以将其搅拌并将碳质材料主要氧化成CO,并吹入铁中的空间中以将CO氧化成CO 2。 随着铁水量的增加,氧气的量增加。 铁屑从氧化产生的热量中熔化。 高温废气用于预热待充电的废料。 当铁水量达到预定水平时,它被分流直到达到较低的预定水平。 重复上述步骤。 双反炉炼铁可采用该方法。 在一个反应​​器中产生的仅一部分CO被氧化,高温废气通入另一个反应器,同时向其中加入氧气以氧化余量并产生更多的热量。 气体的热量和额外的氧化热预热了该反应器中的废料和含碳材料。

    • Disclosed are an improved method of refining steel and an apparatus for practicing the method.The refining method comprises, basically, carrying out the refining, particularly, decarburization, while stirring molten steel in the refining furnace by injecting gas thereinto, while supplying heat with a burner installed at the top of the furnace to the molten steel. According to this method, it is possible to start at an initial carbon content of the moltend steel lower than that of known AOD process, and complete the refining in a curtailed period of time and with a decreased oxidation loss of Cr. Thus, damage of refractory materials of the furnace is reduced, and the amount of Si necessary for reducing Cr-oxides in the latter stage of the refining is also reduced.Oxygen for the decarburization is supplied usually in the form of gas, but can be supplied from a solid oxygen source. In an alternative of the present method, powdery metal oxide, which is reducable equally to or more easily than Cr-oxides, is shot into the furnace through the burner or injected into the molten steel through a tuyere or an immersed lance.Preferably, the burner is of a type of variable flame length. Use of the burner disclosed here makes it possible to lengthened the flame at the former stage of the refining so that not only heat but also oxygen may be supplied to the molten steel surface of promoting the decarburization, and to shorten the flame at the latter stage of the refining so that only heat may be supplied.
    • 公开了一种改进钢的精炼方法和实施该方法的装置。 精炼方法基本上包括进行精炼,特别是脱碳,同时通过在熔炼炉顶部的燃烧炉中对钢水进行加热,同时在精炼炉中搅拌钢液,同时向其中注入气体。 根据该方法,可以从蜕变钢的初始碳含量开始低于已知AOD方法的初始碳含量,并且在缩短的时间段内完成精炼并且减少Cr的氧化损失。 因此,炉的耐火材料的损伤减少,并且在精炼的后期阶段还原Cr氧化物所需的Si量也减少。 用于脱碳的氧气通常以气体的形式提供,但可以由固体氧源供应。 在本方法的替代方案中,与Cr-氧化物同等或更容易还原的粉末金属氧化物通过燃烧器喷射到炉中,或通过风口或浸入式喷枪注入钢水中。 优选地,燃烧器具有可变火焰长度的类型。 这里公开的燃烧器的使用使得可以在炼制的前一阶段延长火焰,使得不仅可以向钢水表面提供热量而且还可以提供氧气以促进脱碳,并且在后一阶段缩短火焰 的精炼,使得仅可以提供热量。
