爐門框架(jia)采(cai)用(yong)槽(cao)鋼(gang)制作,側板和底板采(cai)用(yong)Q235鋼(gang)板焊接,結構牢(lao)固可靠,不易(yi)變形和翹曲,整體強度(du)好。
爐門升降為電動葫蘆驅動。箱式預熱爐廠家在爐門上有一斷路裝置,該裝置與輪軸連鎖,當爐門打開時即切斷加熱元件電源以保證操作人員安全。爐門上裝有調節式密封機構,有效使爐門密封。在爐頂上有一熱電偶孔,在使用時將熱電偶插入爐膛通過電爐控制柜來控制爐膛工作溫度。
控(kong)(kong)(kong)(kong)制(zhi)系統:主控(kong)(kong)(kong)(kong)系統控(kong)(kong)(kong)(kong)制(zhi)柜(ju)采(cai)用(yong)國際流行立(li)式(shi)組合柜(ju)。控(kong)(kong)(kong)(kong)制(zhi)柜(ju)外表(biao)噴涂電(dian)腦(nao)色或淺駝色。電(dian)控(kong)(kong)(kong)(kong)面板上裝(zhuang)有電(dian)流表(biao)、電(dian)壓表(biao)、溫度控(kong)(kong)(kong)(kong)制(zhi)儀及控(kong)(kong)(kong)(kong)制(zhi)開關(guan)等。
溫度(du)控(kong)制(zhi)主(zhu)回路(lu)采用(yong)(yong)可(ke)控(kong)硅過(guo)(guo)(guo)零調功(gong)觸(chu)發,可(ke)控(kong)硅采用(yong)(yong)風冷形式,設有(you)過(guo)(guo)(guo)載、過(guo)(guo)(guo)熱及(ji)過(guo)(guo)(guo)流保護等功(gong)能(neng)(neng)。溫度(du)控(kong)制(zhi)儀(yi)(yi)表(biao)選用(yong)(yong)先進的(de)上海國(guo)龍智能(neng)(neng)高精(jing)度(du)數(shu)顯(xian)PID自整定型儀(yi)(yi)表(biao),控(kong)制(zhi)精(jing)度(du)±1℃。該(gai)溫度(du)控(kong)制(zhi)配(pei)有(you)熱電(dian)(dian)偶修(xiu)正功(gong)能(neng)(neng)、功(gong)率限制(zhi)功(gong)能(neng)(neng)及(ji)超溫報警功(gong)能(neng)(neng)。當爐門打開(kai)時自動切斷加熱主(zhu)電(dian)(dian)路(lu),實現聯鎖保護。
爐溫(wen)記(ji)錄(lu)采用南(nan)通(tong)達(da)華記(ji)錄(lu)儀,對(dui)升溫(wen)及(ji)保溫(wen)時間過(guo)程實時打印曲線、記(ji)錄(lu)溫(wen)度(du),同時對(dui)加熱主回路實現監控作用,有(you)效地監視整個生產工藝。
