鋼包回轉(zhuǎn)臺(tái)用軸承

       鋼包回轉(zhuǎn)臺(tái)是現(xiàn)代連鑄中應(yīng)用普遍的運(yùn)載和承托鋼包進(jìn)行澆注的設(shè)備，通常設(shè)置于鋼水接收跨與澆注跨柱列之間。

所設(shè)計(jì)的鋼包旋轉(zhuǎn)半徑,使得澆鋼時(shí)鋼包水口處于中間包上面的規(guī)定位置。用         鋼水接收跨一側(cè)的吊車將鋼包放在回轉(zhuǎn)臺(tái)上，通過(guò)回轉(zhuǎn)臺(tái)回轉(zhuǎn),使鋼包停在中間包上方供給其鋼水。澆注完的空包則通過(guò)回轉(zhuǎn)臺(tái)回轉(zhuǎn),再運(yùn)回鋼水接收跨。

       鋼包回轉(zhuǎn)臺(tái)是連鑄機(jī)的關(guān)鍵設(shè)備之一，起著連接上下兩道工序的重要作用。鋼包回轉(zhuǎn)臺(tái)的回轉(zhuǎn)情況基本上包括兩側(cè)無(wú)鋼包、單側(cè)有鋼包、兩側(cè)有鋼包三種情況，而單個(gè)鋼包重量已超過(guò)140噸。三種情況下，鋼包回轉(zhuǎn)臺(tái)受力有很大不同，但無(wú)論在何種情況下，都要保證鋼包回轉(zhuǎn)臺(tái)的旋轉(zhuǎn)平穩(wěn)，定位準(zhǔn)確，起停時(shí)要盡可能減小對(duì)機(jī)械部分的沖擊，為減少中間包液面波動(dòng)和溫降，要縮短旋轉(zhuǎn)時(shí)間。因此，我們?cè)谧冾l器的容量選擇上，留有余地，即比電機(jī)功率加大一級(jí)。同時(shí)利用變頻器的s曲線加速功能，通過(guò)調(diào)整s曲線保證加、減速曲線平滑快速，減少對(duì)減速機(jī)的沖擊，再通過(guò)PLC判斷變速限位、停止限位實(shí)現(xiàn)旋轉(zhuǎn)過(guò)程中高、低速自動(dòng)變換及到位停車，同時(shí)滿足了對(duì)旋轉(zhuǎn)時(shí)間和平穩(wěn)運(yùn)行的要求。
