由于導(dao)衛裝置(zhi)(zhi)采用傳統(tong)連接方式 與(yu)軋(ya)機(ji)緊固一體，因傳動(dong)鏈長(chang)、固定支(zhi)點(dian)多，在(zai)生產中經常出現松動(dong)、卡死等(deng)現象(xiang)，誘發軋(ya)制(zhi)事故。為(wei)此，采用以進口導(dao)衛中線為(wei)基準、用孔型找正、實現軋(ya)制(zhi)線統(tong) 一的(de)改進思路，設計了與(yu)軋(ya)機(ji)本體分離的(de)固定導(dao)衛裝置(zhi)(zhi)。應用表明(ming)，改進的(de)導(dao)衛裝置(zhi)(zhi)承(cheng)受(shou)約(yue)180萬次的(de)沖擊無變形，且調整靈活，換(huan)槽(cao)時(shi)間僅為(wei)3min。
