摘要： A method for melting sponge iron is provided in which pieces or pellets of sponge iron, which may be partly replaced by scrap, are placed on the surface of a molten metal bath. Oxygen is added to the metal bath at a position below the surface of the bath. Further substances required for the melting process are added to the metal bath under pressure at a position below the surface of the bath. The further substances that are added include solid carbonaceous dust and fine-grained sponge iron.

摘要： Parasite arcs which occur during the operation of plasma torches have an adverse economic effect and endanger important parts of the torch. Countermeasures of the prior art are only partly effective. Equipping the annular passage between the electrode and the surrounding nozzle which carries the plasma gas with an electrically insulating lining on the inside of the nozzle provides only partial protection. To insulate the segment of the inner wall part of a water-cooled nozzle adjacent to the end wall part by means of insulating parts penetrating the wall part in question from the outer segment is very expensive and complex, depending on the design and the choice of insulation materials. The invention proposes that secondary passages be distributed uniformly between the annular passage for the plasma gas and an annular passage between the nozzle endpiece and the torch casing, uniformly over the circumference. Through these secondary passages, a portion of the plasma gas is diverted and used to cool the nozzle end area and to displace electrically conducting deposits of dusts etc. and plasma arc flashbacks. A flange which is guided so that it slides in this annular passage also acts, by means of relative movements caused by temperature, to prevent the formation of electrical bridges by contaminants.
摘要翻译：在等离子体火炬操作期间发生的寄生弧具有不利的经济效应并危及割炬的重要部分。现有技术的对策仅部分有效。将电极和周围喷嘴之间的环形通道装配在喷嘴内侧上带有电绝缘衬层的等离子体气体仅提供部分保护。为了通过绝缘部件与端壁部分邻近的水冷喷嘴的内壁部分的绝缘部分从外部部分绝缘是非常昂贵和复杂的，这取决于设计和选择保温材料。本发明提出，二次通道在等离子气体的环形通道和喷嘴端部件与割炬套管之间的环形通道均匀分布在圆周上。通过这些二次通道，等离子体气体的一部分被转向并用于冷却喷嘴端部区域并且移置导电的灰尘等沉积物和等离子弧回火。被引导使得其在该环形通道中滑动的凸缘也通过由温度引起的相对运动而起作用，以防止由污染物形成电桥。
