In view of this situation this article has conducted research to the design of metallurgy auxiliary biography with the frequency conversion table electrical machinery first multianalysis to the frequency changer and the frequency conversion table electrical machinery movement characteristic is carried out, the voltage waveform harmonious which the frequency changer outputs is big, attacks in a big way, and the voltage climbing rate reaches as high as 6600v / mu s which is 20 times ordinary sine alternating voltage, the rolling mill auxiliary biography table set the extremely strict request to the electrical machinery ; its movement frequency is very low, rate frequency in 8 - 20hz ; the velocity modulation scope is wide, the lowest movement frequency lowers to 1hz, and the starting number of times is quite frequently, each hour reaches as high as 600 - 800 time, the impact shoulders in a big way, the overload capacity request is high
針對這一情況本文對冶金輔傳用變頻輥道電機的設計進行了系統研究。首先對變頻器和變頻輥道電機的運行特性進行詳細分析，變頻器輸出的電壓波形諧波大，沖擊大，電壓上升率高達6600v / s ，是普通正弦交流電壓的20倍;軋機輔傳輥道對電機提出了十分嚴格的要求:其運行頻率很低，額定頻率在8 - 20hz ;調速范圍寬，最低運行頻率低到0 . 5hz ，起動次數相當頻繁，每小時高達600 - 800次，沖擊負荷大，過載能力要求較高。The actual load data in production is collected by calculating and analyzing the rolling load of a 630 rolling machine in a iron & steel company
通過對某鋼鐵集團公司630軋機軋制負荷的計算分析，得到了軋機的實際生產負荷數據。Excess additive can create over reduction allowing more load on the mill and reducing speed
過量投加會造成過度變形量進而對軋機形成更多的負荷並降低速度。To ensure the safe and normal operating of the machine, the actual work load has been analyzed and the malfunction causes have been rooted, and based on this, the necessary of optimizing the rolling process and optimizing solution have been presented
為保證設備的正常安全運行，對軋機現有負荷和軋制工藝進行了分析，找到引起問題的原因並在此基礎上提出了軋制工藝優化的必要性和優化方案。Compares with the same centripetal ball bearing, has the big radial direction load bearing capacity, mainly is suitable for the cold hot - rolling mill, working roll support rolls and so on cogging mill
與相同的向心球軸承相比，有較大的徑向負荷承載能力，主要適用於冷熱軋機，開坯機等工作輥支承輥。The paper states the configuration, theory of operation and control, realization as well. with the static svc ( tcr ) in operation at the plant, a way similar to rolling mill cycloconverter supply system can be worked out to mitigate harmonic and compensate reactive power
通過本文的工作以及關于重鋼中板廠tcr靜止型動態無功補償裝置的研究，可探索出一條類似交-交變頻供電類軋機負荷供配電系統諧波綜合治理和無功補償的路子。Consumers successively plunged a large number of silicon controlled commuted devices ( such as steel rolling 、 electrized locomotive 、 aluminium electrolysed devices etc ) and smelting devices to improve their produced efficiency or to save energy. on the one hand it is good for consumers, on the other hand it will arouse the fluctuation of voltage and frequency and it will result in the collision of the active and reactance capacity. meanwhile these nonlinear loads bring much harmonic into the electric network which deteriorate the quality of power supply and hazard the online device enormously
用電部門為了提高生產效益、節約能源，在大電網中相繼出現了大量的可控硅整流裝置（如軋鋼、電氣化機車、鋁加工電解設備等）以及冶煉設備，這些設備的投入使用對節能有一定好處，但給電網造成有、無功沖擊，引起電壓和頻率的波動，同時，這些非線性負荷向電網注入大量諧波，大大惡化了供電系統的電能質量，給用電設備帶來了極大的危害。Abstract : the paper analyzes and diagnoses over load operation of 250 heating furnace fan motor at kungang, so real causes are judged correctly. some correspondent measures are taken to satisfy basically the needs of heating furnace operation and steel - rolling production, and avoid occurrence of the equipment accident
