Inkqubo yemveliso yentsimbi eshushu eqengqelekayo ilawula ikakhulu inkqubo yokulungiswa kwebillet, ukufudumeza, ukuhla, ukuqengqeleka okurhabaxa, ukusika intloko, ukugqiba, ukupholisa, ukupholisa nokugqiba.
Iibhilithi zemicu eshushu eqengqelekayo zisoloko ziqhutywa ngamacwecwe okanye amatye aqengqelekayo aqengqelekayo, ukwakheka kweekhemikhali, ukunyamezelwa komgangatho, ukugoba kunye neemilo zokuphela kufuneka zihlangabezane neemfuno, kuba iibhilithi ezilayishiweyo ezibandayo kufuneka zihlolwe, kuba iibhilithi ezilayishiweyo ezishushu kufuneka zibonelele ngeebhilidi ezingenasiphako, okt. umphezulu akufanele ube neziphene ezibonakalayo kwiso lenyama, akufanele kubekho ukuncipha kwangaphakathi, ukukhulula kunye nokwahlula, njl.
Ukufudumala kulawula ubukhulu bokushisa, ixesha, isantya kunye nolawulo lweqondo lokushisa (kubandakanya icandelo lokufudumala, icandelo lokufudumala kunye nokushisa kwecandelo lokufudumeza).Ukuthintela ukutshisa, ukutshisa kakhulu, i-oxidation, i-decarburisation okanye ukunamathela kwentsimbi.Kukhethwa ukusebenzisa isithando sokufudumala sesinyathelo, esinenzuzo kumgangatho ophezulu.
Izixhobo zokunciphisa ngoomatshini bokwehlisa umqulu osicaba, oomatshini bokwehlisa umqulu othe nkqo kunye neebhokisi zokuthoba amanzi ezinoxinzelelo oluphezulu.Isetyenziselwa ngokubanzi ukususa ulusu lwe-iron oxide ngokuqengqeleka imida ngeeroli ezithe nkqo emva koko usebenzisa amanzi oxinzelelo oluphezulu (10-15 MPa).
Indima ye-rough rolling kukuxinzelela kunye nokwandisa i-billet ukubonelela umqulu wokugqiba nge-billet yobukhulu obufunekayo kunye nokuma kweplate.Inkqubo yokuqengqeleka rhabaxa kufuneka ilawulwe ngokuseta isixa kunye nesantya sokugqitha ngakunye kokucinezela phantsi, ukwandisa ubushushu bemveliso yeyunithi eqengqelekayo kangangoko kunokwenzeka, nokuqinisekisa ubukhulu nobubanzi bebillet eqengqelekayo.Ukuze unciphise umgama phakathi kweendawo zokumisa, iindawo ezimbini zokugqibela zeseti yokungqusha zicwangciswe ngendlela eqhubekayo.
Ukusika intloko kukususa intloko kunye nomsila we-billet rolling rough, ukuququzelela ukugqiba ukuluma kunye nomatshini ojikelezayo.
Ukugqitywa kwe-rolling kuhambelana nemimiselo yokuguqa kwi-rack nganye phantsi komlinganiselo woxinzelelo, ukushisa kwe-rolling, isantya sokuhamba.Ngokuqhelekileyo ilawulwa ngokulinganayo okwesibini ukuhamba okanye imodi yoxinzelelo oluqhubekayo.I-Hydraulic okanye i-AGC yombane isetyenziselwa ukulawula ubukhulu, kwaye ulawulo lobushushu lwenkqubo yokuqengqeleka lubandakanya ubushushu bokugqibela bokuqengqeleka kunye nentloko kunye nomsila wolawulo umahluko wobushushu.Ukuze ulawule imilo yephepha, iiprofayili zomqulu kunye nezixhobo zokugoba kwangaphambili zisetyenziselwa ukuqinisekisa umahluko wobunzima obunqamlezileyo bomcu.
Ubushushu bomcu wentsimbi yi-900 ukuya kwi-950 ° C emva kokugqiba ukuqengqeleka kwaye kufuneka bupholiswe ukuya kuma-600 ukuya kuma-650 ° C kwimizuzwana embalwa ngaphambi kokuba iqengqeleke.Ukupholisa iLaminar kunye nokupholisa amakhethini amanzi ngokuqhelekileyo kusetyenziswa.Ukupholisa ukuhamba kweLaminar kukusetyenziswa koxinzelelo lwamanzi aphantsi kunye nesixa esikhulu sokupholisa kwamanzi, ngokutsho kobunzima bomcu kunye nobushushu bokugqibela bokuqengqeleka kulungelelanisa ubungakanani bamanzi.Ukupholisa komkhusane wamanzi komcu ufana, ukukhawuleza kunye nomthamo wokupholisa ophezulu.
Ukuze kuqinisekiswe ukuba umbutho kunye neepropati zomtya oshushu zihlangabezana neemfuno, intsimbi egobileyo kufuneka igqitywe kwiqondo lokushisa eliphantsi kunye nesantya esiphezulu, ubushushu obujikeleziweyo buhlala kwi-500 ~ 650 ℃.Ubushushu bokubhijela buphezulu kakhulu, iinkozo ezirhabaxa.
