    艾默生EV2000系列變頻器在無(wú)縫鋼管帶鋸機(jī)上的應(yīng)用

    Application of EMERSON EV2000 Series Frequency Converter to Band Sawing Machine for Seamless Steel Tube

    • 摘要: 介紹了艾默生EV2000系列變頻器在攀鋼集團(tuán)成都鋼鐵有限責(zé)任公司精密軋管廠Φ400 mm帶鋸機(jī)上的應(yīng)用情況。在高速帶鋸機(jī)鋸切圓形鋼管坯料的生產(chǎn)線中,輸入輥道電機(jī)采用集中變頻控制,輸出輥道電機(jī)采用變頻控制,便于坯料的傳輸和精確定位;帶鋸機(jī)主電機(jī)也采用變頻器和變頻電機(jī)拖動(dòng),實(shí)現(xiàn)帶鋸條的無(wú)級(jí)調(diào)速,可以針對(duì)不同直徑大小的坯料而選擇不同的鋸切速度。實(shí)際應(yīng)用表明,該系列變頻器運(yùn)行良好,控制效果佳,故障率低且投資適中。

       

      Abstract: Described in the article is the application of EMERSON EV2000 Series frequency converter to the Ф 400mm band sawing machine incorporated with the Accu-Roll Precision Tube Rolling Plant of Pangang Group Chengdu I & S Co.,Ltd..For cutting round steel billets with hi-speed band sawing machine,the inlet roller conveyor motors are centralized-inverter controlled,while the outlet roller conveyor motors are frequency-changing controlled to ensure smooth transport and accurate positioning of the material.The main drive of the band sawer is dragged by means of converter and frequency-changing motor for bring about infinite speed regulation of the band saw as per billet size.Actual operation shows that the said series of frequency converter features appropriate running,desirable control effectiveness,low failure rate and moderate investment.
