回轉窯的(de)(de)滾(gun)(gun)圓(yuan)(yuan)(yuan)的(de)(de)截(jie)(jie)(jie)面(mian)(mian)(mian)形(xing)(xing)(xing)式(shi)，（1）矩形(xing)(xing)(xing)滾(gun)(gun)圓(yuan)(yuan)(yuan)其(qi)截(jie)(jie)(jie)面(mian)(mian)(mian)是實心矩形(xing)(xing)(xing)，形(xing)(xing)(xing)狀(zhuang)簡(jian)單，由于截(jie)(jie)(jie)面(mian)(mian)(mian)體的(de)(de)，鑄(zhu)造(zao)(zao)(zao)缺(que)陷(xian)(xian)相(xiang)對(dui)來說(shuo)不明顯(xian)突出，裂縫(feng)少(shao)。矩形(xing)(xing)(xing)滾(gun)(gun)圓(yuan)(yuan)(yuan)可(ke)以(yi)鑄(zhu)造(zao)(zao)(zao)也可(ke)以(yi)用鍛(duan)造(zao)(zao)(zao)。我國一(yi)些(xie)(xie)制造(zao)(zao)(zao)廠已采用大型水壓擠鍛(duan)制滾(gun)(gun)圓(yuan)(yuan)(yuan)。張店鋁廠為(wei)解決回轉窯(yao)矩形(xing)(xing)(xing)滾(gun)(gun)圓(yuan)(yuan)(yuan)的(de)(de)備件(jian)問(wen)題，采用了電(dian)(dian)渣(zha)焊(han)工藝，克(ke)服電(dian)(dian)爐容量(liang)小的(de)(de)困難(nan)。將(jiang)5100毫(hao)米，凈重18.6噸的(de)(de)滾(gun)(gun)圓(yuan)(yuan)(yuan)分(fen)四半鑄(zhu)造(zao)(zao)(zao)，用電(dian)(dian)渣(zha)焊(han)焊(han)成(cheng)整體毛培(pei)，在(zai)簡(jian)易環形(xing)(xing)(xing)隧道爐內退火，消除焊(han)接應力后再行加工。使用效果(guo)良好。回轉窯(yao)箱式(shi)滾(gun)(gun)圓(yuan)(yuan)(yuan)剛性大，有利于增強回轉窯(yao)筒體剛度，與矩形(xing)(xing)(xing)相(xiang)比可(ke)節約材料。但由于截(jie)(jie)(jie)面(mian)(mian)(mian)形(xing)(xing)(xing)狀(zhuang)復雜，鑄(zhu)造(zao)(zao)(zao)時，在(zai)冷(leng)縮過程中(zhong)易產生裂縫(feng)等(deng)缺(que)陷(xian)(xian)，這些(xie)(xie)缺(que)陷(xian)(xian)有時導致橫截(jie)(jie)(jie)面(mian)(mian)(mian)斷裂。由于箱式(shi)滾(gun)(gun)圓(yuan)(yuan)(yuan)內圓(yuan)(yuan)(yuan)中(zhong)部有一(yi)段不加工，因此可(ke)設計(ji)成(cheng)帶(dai)鍵滾(gun)(gun)圓(yuan)(yuan)(yuan)。凸出的(de)(de)鍵由倆快墊板加緊，阻止了滾(gun)(gun)圓(yuan)(yuan)(yuan)與墊板間沿周向相(xiang)對(dui)滑動。
