摘要： An electric arc furnace pivotable between a first position wherein a gas delivery tuyere system is above the level of a metal charge for preheating the same and a second position wherein the tuyere system is below the level of metal charge to permit the injection of gases, fluxes, ores, alloying additions and other materials for converting a metal charge. A first furnace hood is engageable with the furnace when in its first position for positioning electrodes in the furnace and a second hood is engageable with the furnace when in its second position for withdrawing gases evolved during the gas blowing period.

摘要： A steel conversion method includes the steps of delivering a first quantity of oxygen and a surrounding sheath of hydrocarbon shielding fluid beneath the level of a quantity of molten ferrous metal or bath contained in a vessel by means of bottom tuyeres and simultaneously delivering a second quantity of oxygen to the bath from above through a top lance. The oxygen delivered through the bottom tuyeres is sufficient to promote mixing and is about 10% to 40% of the oxygen required for oxidation of impurities with the balance delivered through the top lance. An additional quantity of oxygen is delivered through the top lance to the space above the bath for post-combustion of off-gases to increase the thermal energy in the bath. Fluxes such as lime are added from above in lump form in the conventional manner or are entrained in the upper oxygen stream as required. As the level of carbon in the bath falls toward desired levels, an inert gas is introduced through the bottom tuyeres at an increased rate while the proportion of oxygen is decreased.
摘要翻译：钢转化方法包括以下步骤：通过底部风嘴将第一量的氧气和周围的碳氢化合物保护液体鞘输送到容纳在容器内的熔融黑色金属或浴液的水平面下，同时输送第二量的氧气从上面通过顶部喷枪进入浴缸。通过底部风嘴输送的氧气足以促进混合，并且是通过顶部喷枪输送的平衡物，氧化杂质所需的氧气的约10％至40％。额外的氧气通过顶部喷枪输送到浴槽上方的空间，用于后处理废气以增加浴中的热能。助熔剂如石灰以常规方式从块状形式加入，或根据需要夹带在上部氧气流中。随着浴中的碳水平下降到所需水平，惰性气体以增加的速率通过底部风嘴引入，同时氧气的比例降低。

摘要： The flue gases from a steel refining furnace or vessel are delivered to a gas cleaning system in which the dust is removed and collected in slurry form. The slurry is dried and reduced to dust again after which it is delivered to a storage vessel. The dust is transported pneumatically from the storage vessel to tuyeres in the steel refining vessel and thereby injected back into the molten metal within the vessel. The dust is rich in iron oxide and contributes to the steel yield from the refining vessel.

摘要： A tuyere assembly for use in metallurgical vessels includes a tubular metallic tuyere housing which is cast in a block of refractory material. When the tuyere block is installed in a metallurgical vessel, a tuyere is inserted within the tubular tuyere housing and the space between the tuyere assembly and the housing sealed with a suitable refractory material. After a significant portion of the tuyere assembly has burned away during metallurgical operations, the tuyere may be withdrawn from the tuyere housing and a new tuyere substituted. Any refractory lining which has burned away in the vicinity of the new tuyere may be built up with a chemically bonded gunning mixture which sets to form a dense refractory material around the tuyere assembly.
