I-Hot-rolled isekelwe kwi-slab (ikakhulukazi i-billet) njengento ekrwada, ifudunyezwe yi-mill ehlabayo kunye neqela lokugqiba i-mill eyenziwe ngentsimbi.Ukususela ekugqityweni kweyokugqibela kwi-hot strip mill ngokupholisa i-laminar ukuya kwiqondo lokushisa elibekiwe, umatshini wokudibanisa u-coil rolling coil strip metal, i-steel roll ipholile ngeendlela ezahlukeneyo zokucutshungulwa komgca wokugqiba kwaye ibe yintsimbi, umthamo osicaba kunye nemveliso yensimbi yokuqhawula.

Umzobo obandayo uthetha kwiqondo lokushisa, emva kokubanda-umzobo, ukugoba, umzobo kunye nenye ipleyiti ebandayo okanye i-strip ekuqhutyweni kweentlobo ezahlukeneyo zetsimbi.

Ishushu-isolwe kwayeipholile umahluko:

I-1, i-Hot rolling kunye nentsimbi epholileyo eyenziwe ngentsimbi okanye ipleyiti yensimbi yokwenza inkqubo iyafana, banempembelelo enkulu kwi-microstructure kunye neempawu ze-mechanical zentsimbi, intsimbi eqengqelekayo, i-hot-rolled ikakhulukazi isekelwe, intsimbi epholileyo esetyenziselwa ukuveliswa kuphela. encinci kunye neshiti.

I-2, i-cold-formed steel cross-section ibonakala ivumela i-buckling yendawo, enokuthi isebenzise ngokupheleleyo intonga yokuthwala intonga emva kwe-buckling;ngelixa i-hot-rolled steel ayivumeli i-cross-section ye-buckling yendawo eyenzekayo.

I-3, Ngenxa yezizathu ezahlukeneyo intsimbi eshushu-eshushu kunye nentsimbi epholileyo yokuxinzelela intsalela, ngoko ke ukuhanjiswa kwecandelo lomnqamlezo kukwahluke kakhulu.Intsimbi epholileyo yokusabalalisa uxinzelelo oluseleyo kwi-cross-section igobile, kunye nentsimbi eshushu egobileyo okanye icandelo lentsimbi edibeneyo yokusabalalisa uxinzelelo oluseleyo luhlobo lwefilimu.

I-4, Inkululeko yentsimbi eshushu-eqengqelekayo epholileyo yentsimbi ephezulu yokuqina kwe-torsional, ngoko ke ukusebenza kwe-torsional kungcono kunentsimbi eshushu eqengqelekayo.

I-5, Inkqubo yokufudumala eshushu: ityhubhu - ukufudumeza - i-punch eshushu - i-rolling - ibhedi yokupholisa, inkqubo yokudweba ebandayo: ukuqala - imingxuma yokubhobhoza - i-pickling - i-phosphate - i-annealing.
