★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★★每年汛期,江河流域都  作为一台完全靠电磁力驱动并且与金属溶液无接触的金属溶液搅拌设备,电磁搅拌机可提高合金的整体均匀度,缩短熔炼时间,减少烧损,提高产品质量。本文主要介绍了Goodrive800四象限变频器应用在电磁搅拌设备上的优点。

前言


由于其具有各种优点,比如无接触污染、均匀的溶液温度、较短的熔炼时间、相同的化学成分、减少氧化渣、低烧损、高指数可控性和高电气化水平,作为金属冶炼过程中的关键设备,电磁搅拌机已广泛应用于冶金行业。变频电源是电磁搅拌机的重要组成部分,其特点决定了金属冶炼的质量、节能效果、搅拌质量指数。一般来说,电磁搅拌机的传统电源是AC-AC或两象限AC-DC-AC,其中存在许多缺陷,比如功率因数低、谐波干扰大、电网能量回馈不可行、突然断电时容易致使爆炸事故。而四象限变频器可以科学配置,给电磁搅拌系统提供变频电源,从而可避免传统电源的诸多缺陷。


I.工作原理


感应电磁搅拌机主要由变频电源和电感器组成。根据电磁感应原理,高强度的磁场作用于金属溶液(导体),因此使得它有规律地移动。变频电源改变50/60Hz交流工频为可调输出电压0.5~5.0Hz 变频分离低频电源,当电源通过电感器时形成交替移动磁场,移动磁场通过穿透在炉底部的不锈钢板对金属溶液产生作用,在磁场的作用下,金属溶液产生感应电动势和感应电流,同时在磁场的交互作用下,感应电流产生电磁力,从而使金属溶液有规律地移动,达到溶液搅拌的目的。改变移动磁场的方向和强度能有效地控制金属液的搅拌方向和强度。电磁搅拌示意图如图(1)所示。
