摘要： The invention relates to a method and an arrangement for measurement of electrode paste in an electrode column of an electric arc furnace. The electrode column (10) comprises a steel casing (11) surrounding the electrode paste and said electrode column (10) is provided with a contact shoe ring (12) to conduct electric current to the electrode. The electrode column (10) is filled with electrode paste by introducing said paste from above into the steel casing (11). The electrode paste evolves through different phases, from raw paste in the upper part of the steel casing (11) to melted paste and further to baked paste (18) in the lower part of the electrode column (10). In the invention a plurality of laser devices is provided on the top of the electrode column (10). The level of the raw paste (16) corresponding to the height of the paste cylinder in the steel casing (11) is determined with the laser beam transmitted by a first laser device. The level of the molten paste (17) in the steel casing (11)is determined with the laser beam transmitted by a second laser device. The data received from the laser devices is used for calculation of the distances of the levels of the raw paste (16) and molten paste (17) from the contact shoe ring(12).
摘要翻译：本发明涉及电弧炉电极柱中电极糊的测量方法和装置。电极柱（10）包括围绕电极浆料的钢壳体（11），并且所述电极柱（10）设有接触靴环（12），以将电流传导到电极。通过将上述糊料从上方引入钢壳体（11）中，电极柱（10）填充有电极浆料。电极浆料从钢壳（11）的上部的原料糊料到熔融糊料，并进一步在电极柱（10）的下部的烘烤糊料（18）的不同阶段形成。在本发明中，在电极柱（10）的顶部设有多个激光装置。利用由第一激光装置传输的激光束来确定对应于钢壳体（11）中的糊料筒的高度的生糊料（16）的水平。钢壳（11）中的熔融糊（17）的高度由用第二激光装置传输的激光束确定。从激光装置接收的数据用于计算生胶（16）和熔融膏（17）的水平距离接触靴环（12）的距离。

摘要： A method and a system for monitoring clamping pressure exerted by a clamping cylinder to an electrode in an electrode slipping device which comprises an upper annular holderringand a lower annular holderring, each comprising at least one clamping assembly including a clamping shoe and clamping cylinder arranged in co-operation so that the clamping shoe is forced into pressure contact with the electrode and released from pressure contact with the electrode by the action of the clamping cylinder. The measuring system comprises a force sensor (30) mounted in connection with a pressing piece (22) that transmits the force created by the clamping cylinder to the clamping shoe. The force sensor can be a strain gage (30) mounted in a cavity (25) provided in the pressing piece (22) or a load cell mounted between the pressing piece (22) and the clamping cylinder.

摘要： The invention relates to an arrangement for cooling channels in an electrode column assembly of an elec- tric arc furnace, wherein the lower part of theelec- trode column assembly isprovided with a contact shoe ring formed of a plurality of contact shoe elements (31), a pressure ring formed of a plurality of pres- sure blocks, and a heat shield located above the pres- sure ring and formed of a plurality of heat shield segments. The contact shoe elements (31) and/orthe pressure blocks are provided with channels (35, 36) fora cooling liquid to flow therein. The channels (35, 36) made in the material of the contact shoe ele- ments (31) and/orthe pressure blocks extend obliquely downwards from the upper ends (33) of said contact shoe elements (31) and/orthe pressure blocks near to the lower ends (34) of the same. At least two of said oblique channels (35, 36) in a same contact shoe ele- ment (31) and/orpressure block join together at their lower ends near the lower ends (34) of the contact shoe elements (31) and/orthe pressure blocks to form a continuous channel (35, 36) in each contact shoe el- ement (31) and pressure block.
