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。 -
However, this approach is faced with two key challenges. first is the keen competition from fast emerging ports in southern china, in particular the prd region, which has been assessed in the latest round of the study on port cargo forecasts. one of the conclusions of the study was that although neighbouring ports offer lower monetary costs, ours has the advantages in terms of high frequency of callings, extremely efficient operation and associated logistics services
首先是華南一帶的港口，近年冒升之勢甚速，儼然成為香港的強大競爭對手，其中尤以珠江三角洲的港口為甚；我們已透過最新的港口貨運量預測研究，分析這趨勢對我們的影響；研究結論指出，雖然珠江三角洲港口收費低廉，但香港卻在頻密的船期，作業迅速有效，以及物流增值服務上，較鄰近港口優勝。 -
It takes to you the integrity during complete wonder, the high school low frequency all processes qia arrives the advantage, has not exploded the tendency, actually has extremely richly, extremely has elastically low frequency, moreover is in no way muddy, regardless of from selects a song arrange which, dubs in music, also perhaps is high, center, the low frequency technical utilization, again perhaps the prelude, plays the rhythm which, the tail plays, in abundantly picks in the audiences long foundation all has the unprecedented innovation
它帶給你完整無缺的美妙，高中低頻均處理得洽到好處，沒有膨爆的動態，卻有極其豐富，極具彈性的低頻，而且決不混濁，無論從選曲、配樂的編配，亦或是高、中、低頻的技術運用，再或是前奏、間奏、尾奏的韻律，在博採眾長的基礎上都有前所未有的創新。 -
