Inqubo yokukhiqiza yensimbi egoqiwe eshisayo ilawula ikakhulukazi inqubo yokulungiswa kwe-billet, ukufudumeza, ukwehla, ukugoqa okungalungile, ukusika ikhanda, ukuqeda, ukupholisa, ukugoqa nokuqeda.
Amabhilidi emigqa egoqelwe ngokushisayo ngokuvamile ama-cast slabs aqhubekayo noma ama-primary rolled slabs, ukwakheka kwamakhemikhali, ukubekezelelana kobukhulu, ukugoba kanye nokuma kokugcina kufanele kuhlangabezane nezimfuneko, ngoba amabhilidi alayishiwe abandayo kufanele ahlolwe, ngoba amabhilidi alayishiwe ashisayo kufanele anikeze amabhilidi angenasici, okungukuthi. indawo engaphezulu akufanele ibe neziphambeko ezibonakala ngeso lenyama, akufanele kube nokuncipha kwangaphakathi, ukuxega nokuhlukaniswa, njll.
Ukushisa kulawula ngokuyinhloko izinga lokushisa lokushisa, isikhathi, isivinini kanye nombuso wokushisa (kuhlanganise nesigaba sokushisa, isigaba sokushisa ngisho nokushisa kwesigaba sokushisa).Vimbela ukushisa ngokweqile, ukushisa ngokweqile, i-oxidation, i-decarburisation noma ukunamathela kwensimbi.Kungcono ukusebenzisa isithando sokushisa isinyathelo, esizuzisa ikhwalithi ephezulu.
Imishini yokwehliswa yimishini yokwehlisa amaroli ayisicaba, imishini yokwehlisa amaroli aqondile kanye namabhokisi okwehlisa amanzi anengcindezi ephezulu.Isetshenziswa kabanzi ukususa isikhumba se-iron oxide ngokugoqa imiphetho ngemiqulu eqondile bese usebenzisa amanzi anomfutho ophezulu (10-15 MPa).
Iqhaza lokugoqa okunzima ukuminyanisa nokwelula i-billet ukuze kuhlinzekwe umqulu wokuqeda nge-billet yosayizi odingekayo kanye nokuma kwepuleti.Inqubo yokuginqika emangelengele kufanele ilawulwe ngokusetha inani nesivinini sokudlula ngakunye kokucindezela phansi, kukhushulwe izinga lokushisa eliphumayo leyunithi egoqayo ngendlela engenzeka, kanye nokuqinisekisa ukujiya nobubanzi be-billet egoqayo.Ukuze kuncishiswe ibanga phakathi kwezitendi, izitendi ezimbili zokugcina zesethi yokugaya zihlelwa ngendlela eqhubekayo.
Ukusika ikhanda ukususa ikhanda nomsila we-billet egoqayo, ukusiza ukuqeda ukulunywa kokugaya kanye nomshini wokusonga.
Ukuqeda ukugoqa kuhambisana nemithetho yokugoqa ye-rack ngayinye ngaphansi kwenani lokucindezela, izinga lokushisa elijikelezayo, isivinini sokugoqa.Ngokuvamile kulawulwa ukugeleza kwesibili okulinganayo noma imodi yokucindezeleka engaguquki.I-Hydraulic noma i-AGC kagesi isetshenziselwa ukulawula ukujiya, futhi ukulawulwa kwezinga lokushisa kwenqubo yokugingqika kuhlanganisa izinga lokushisa lokugcina eliginqikayo kanye nokulawula umehluko wokushisa kwekhanda nomsila.Ukuze kulawulwe ukuma kweshidi, amaphrofayili amaroli kanye namadivayisi agoqayo ngaphambili asetshenziswa ukuze kuqinisekiswe umehluko wogqinsi ovundlanayo womucu.
Izinga lokushisa lomugqa wensimbi lingama-900 kuya ku-950°C ngemva kokuqeda ukuginqika futhi kufanele lipholiswe libe ku-600 kuya ku-650°C phakathi kwemizuzwana embalwa ngaphambi kokuba ligoqwe.Ukupholisa i-laminar kanye nokupholisa amakhethini amanzi ngokuvamile kusetshenziswa.Ukupholisa ukugeleza kwe-laminar ukusetshenziswa komfutho wamanzi ophansi kanye nenani elikhulu lokupholisa amanzi, ngokusho kobukhulu be-strip kanye nezinga lokushisa lokugcina lokugoqa ngokuzenzakalelayo lilungisa inani lamanzi.Ukupholisa ikhethini lamanzi kwe-strip kufana, kuyashesha futhi kuphezulu amandla okupholisa.
Ukuze kuqinisekiswe ukuthi inhlangano kanye nezakhiwo zomugqa ogoqelwe oshisayo zihlangabezana nezidingo, insimbi egoqiwe kufanele igoqwe ezingeni lokushisa eliphansi kanye nesivinini esiphezulu, izinga lokushisa eligoqiwe livamise ukuba ku-500 ~ 650 ℃.Izinga lokushisa lekhoyili liphezulu kakhulu, okusanhlamvu okumahhadla.
