摘要： A method of melting iron scrap using an arc furnace with reduced electric power consumption.In one of a pair of vessels which are arc furnace bodies, melting of the scrap by heat of arc is carried out while a carbonaceous material and oxygen-containing gas are introduced therein to cause oxidation of C to CO to make use of the oxidation heat. Thus formed hot exhaust gas containing CO is introduced to the other vessel of the pair and oxygen-containing gas is added thereto to cause oxidation of CO to CO.sub.2 thereby heating the scrap loaded in the vessel. Melting is further continued by changing the roles of the two vessels to each other.Generation of the CO-containing hot gas can be performed in a separately installed gasification furnace.
摘要翻译：使用电弧炉熔炼废铁的方法，降低电力消耗。在作为电弧炉体的一对容器中的一个中，通过电弧的热量熔化废料，同时将碳质材料和含氧气体引入其中以使C氧化成CO以利用氧化热。将这样形成的含有CO的热废气引入到该对的另一个容器中，并向其中加入含氧气体以使CO氧化成CO 2，从而加热装载在容器中的废料。通过改变两艘船的作用相互进一步地进行融化。含CO的热气体的生成可以在分开设置的气化炉中进行。

摘要： An improvement to a scrap melting method employing an electric arc furnace, which comprises the step of heating the scrap by a powdered coal burner prior to the step of heating the scrap by the electric arc. The burning conditions are controlled so as to reduce the amount of oxidized Fe as well as the amount of NO.sub.x contained in the exhaust gases. In preferred embodiments, a pair of furnaces are employed to heat the scrap alternately by the powdered coal burner and by the electric arc.

摘要： The specification discloses a ladle furnace apparatus for refining molten steel tapped from a steelmaking furnace therein. There are introduced molten steel and a slag making material into the ladle. The outer and inner lids of the ladle furnace are put on the respective receiving surfaces of the ladle to close the opening thereof. In the interior of the ladle, the slag making material is slagged by arc heating thereby to refine molten steel introduced therein by means of the slag. During the refining process, the suction of gas is carried out from a space formed between the outer lid and the inner lid. Therefore, a dust containing gas generated by reaction of the molten steel and slag enters the space between the outer lid and the inner lid passing through a gap formed between the inner lid and the ladle or electrode holes disposed in the inner lid to be sucked therefrom. Even if the open air enters the apparatus through a gap between the outer lid and the ladle, the open air does not flow inside of the inner lid. Therefore, it is possible to prevent the temperature of slag from being lowered due to the open air. In addition, it is also possible to prevent the refining efficiency of slag on the molten steel from being lowered. Consequently, refining on the molten steel can efficiently be performed.
摘要翻译：本说明书公开了一种钢包炉装置，用于从其中的炼钢炉中精炼钢水。将钢水和造渣材料引入钢包中。钢包炉的外盖和内盖都放在钢包的相应的接收表面上，以便关闭其开口。在钢包的内部，通过电弧加热对造渣材料进行排渣，从而通过炉渣精炼引入其中的钢水。在精炼过程中，气体的抽吸是从形成在外盖和内盖之间的空间进行的。因此，通过钢水和炉渣的反应而产生的含尘气体进入到通过内盖和钢包之间形成的间隙的外盖和内盖之间的空间或设置在内盖中的电极孔，从而被吸入。即使露天空气通过外盖和钢包之间的间隙进入设备，露天空气也不会流入内盖内部。因此，可以防止由于露天而导致的炉渣的温度降低。此外，还可以防止钢水上的炉渣的精炼效率降低。因此，可以有效地进行钢水的精炼。

摘要： During the heating of scrap in a container using sulfur-containing fuels for combustion, CaO, Ca(CO).sub.2, or CaCO.sub.3 powder is injected into the container to fix sulfur oxides generated during the combustion mainly as CaSO.sub.4. There is no need for special exhaust gas desulfurization, and, at the same time, slag formation is possible.

摘要： A powdered coal burner used for directly heating an object to be heated, particularly iron scrap, in a heating vessel. The burner is composed of an oxygen nozzle, a powdered coal nozzle, an air nozzle, disposed concentrically from the center, and a cone which is provided at the end of the opening part of the oxygen nozzle in such a way as to disperse oxygen in a radial direction and burn powdered coal. The burner burns with shortened length of flame, and temperature of the flame is not excessively high.
