結(jie)晶(jing)器(qi)(qi)是連(lian)(lian)鑄(zhu)(zhu)過程中鋼(gang)水凝固的(de)(de)第1個冷(leng)(leng)卻(que)段，也是整個冷(leng)(leng)卻(que)過程中最重要的(de)(de)階段，它(ta)對鑄(zhu)(zhu)坯(pi)(pi)的(de)(de)形成(cheng)和表面質量起著決定性(xing)的(de)(de)作用，故結(jie)晶(jing)器(qi)(qi)常被稱(cheng)為連(lian)(lian)鑄(zhu)(zhu)機的(de)(de)“心臟”，如荊德君等利用數值(zhi)模(mo)擬的(de)(de)方法研(yan)究了(le)連(lian)(lian)鑄(zhu)(zhu)結(jie)晶(jing)器(qi)(qi)內(nei)鑄(zhu)(zhu)坯(pi)(pi)溫(wen)度場和應力(li)；馮科等模(mo)擬研(yan)究了(le)板坯(pi)(pi)連(lian)(lian)鑄(zhu)(zhu)結(jie)晶(jing)器(qi)(qi)銅(tong)板溫(wen)度場；楊曉江等研(yan)究了(le)非均(jun)勻冷(leng)(leng)卻(que)型結(jie)晶(jing)器(qi)(qi)銅(tong)板的(de)(de)傳熱特性(xing)。

　　科研工作者以實(shi)際生產(chan)過程(cheng)中倒角結晶(jing)器(qi)的銅(tong)(tong)板尺寸、水道(dao)布(bu)置、銅(tong)(tong)板實(shi)測溫度、寬窄面(mian)水量(liang)和進出水溫差為基礎(chu)，運用(yong)商業軟件ANSYS模擬了(le)實(shi)際生產(chan)過程(cheng)中倒角結晶(jing)器(qi)銅(tong)(tong)板溫度分(fen)布(bu)。

　　計(ji)算結(jie)果表明：距(ju)彎(wan)月(yue)(yue)面(mian)0～300mm，倒(dao)角(jiao)結(jie)晶(jing)(jing)器窄面(mian)橫向溫(wen)(wen)度(du)(du)分布(bu)呈(cheng)W型(xing)，和直角(jiao)結(jie)晶(jing)(jing)器倒(dao)U型(xing)溫(wen)(wen)度(du)(du)分布(bu)有很大(da)差別；距(ju)彎(wan)月(yue)(yue)面(mian)300～800mm，角(jiao)部溫(wen)(wen)度(du)(du)迅速降低，溫(wen)(wen)度(du)(du)分布(bu)呈(cheng)倒(dao)U型(xing)，和直角(jiao)結(jie)晶(jing)(jing)器溫(wen)(wen)度(du)(du)分布(bu)基本一致(zhi)；此外，倒(dao)角(jiao)結(jie)晶(jing)(jing)器倒(dao)角(jiao)面(mian)的溫(wen)(wen)度(du)(du)梯(ti)度(du)(du)較大(da)，倒(dao)角(jiao)面(mian)上坯殼(ke)與銅(tong)板之(zhi)間的換熱熱流波動較大(da)，這說明倒(dao)角(jiao)坯的缺陷主要出(chu)現在倒(dao)角(jiao)面(mian)，這與實際(ji)是相符合(he)的。
