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140噸。三種情況下,鋼包回轉(zhuǎn)臺(tái)受力有很大不同,但無論在何種情況下,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PLC判斷變速限位、停止限位實(shí)現(xiàn)旋轉(zhuǎn)過程中高、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。
