我們有內部的軋輥，鍛造和機床加工這樣的技術，有能力去生產所有類型的魚尾板包括普通魚尾板，嚙合型魚尾板，角形魚尾板和組合型魚尾板根據各種各樣的圖紙為各種各樣的鐵路。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。Prestressed rolling mill is a kind of rolling mill with short stress line and great rigidity. compare with the same type of common rolling mill, it has great rigidity, simple structure and light weight, and is easily assembled and disassembled
預應力軋機是一種短應力線的高剛度軋機，與同規格的普通軋機相比，具有剛度高、結構形式簡單、重量輕、裝拆方便的優點。
