摘要： The present invention relates to a method for continuous production of elongated carbon bodies, particularly carbon electrodes which are produced in direct connection with the smelting furnace wherein the electrodes are consumed, where a metallic casing containing unbaked carbonaceous electrode paste comprising a particulate solid carbon material and a carbonaceous binder is continuously or substantially continuously lowered through a baking furnace which is heated to a temperature between 500 and 1200° C., whereby the unbaked electrode paste is baked into a solid carbon body and where the casing is extended by joining new sections of casing on the top of the casing as the casing is lowered through the baking furnace, where the lower part of each section of casing has an outer diameter that is equal to or smaller than the inner diameter of the upper part of each section of casing, said method being characterized in that each new section of casing is mounted upon the section of casing below in such a way that the lower part of the new section of casing is positioned inside the casing of the upper part of the section of casing situated below the new section of casing and where the length of the lower part of each section of casing has such an extension that the new section of casing during baking freely can slide downwards in relation to the section of casing situated below the new section of casing a distance which at least compensates for the shrinkage of the electrode paste contained in the casing during baking of the carbon body in the baking furnace.
摘要翻译：本发明涉及一种连续生产细长碳体的方法，特别是与其中电极被消耗的熔炼炉直接连接生产的碳电极，其中含有包含微粒固体碳材料的未煅烧碳质电极浆料的金属外壳和碳质粘合剂连续地或基本上连续地通过加热到500-1200℃的烘烤炉降低，由此将未烘烤的电极糊烘焙成固体碳体，并且在外壳通过烘烤炉降低时，通过在外壳顶部连接新的外壳部分来延伸外壳，其中每个部分的下部的外壳具有等于或小于每个外壳部分的上部的内径的外径，所述方法的特征在于，每个新外壳部分以如下方式安装在下部外壳部分上：新壳体部分的下部位于位于壳体新部分下方的壳体部分上部壳体的内部，并且每个壳体部分下部的长度具有这样的延伸部分，以使新在烘烤过程中自由烘烤的部分可以相对于位于壳体新部分下方的壳体部分向下滑动一段距离，该距离至少补偿所包含的电极糊的收缩在烘烤炉中烘烤碳体期间的壳体中。
