Intsimbi eshushu eqengqelekayo
I-Hot-rolled ine-slab eqhubekayo yokuphosa okanye i-slab eqhakaza njengento ekrwada, emva kokufudumeza ukufudumala kwesithando somlilo, uxinzelelo oluphezulu lwamanzi ehla kwi-mill e-roughing, i-roughing material ngentloko yokusika, umsila, kwaye emva koko ungene kwindawo yokugqiba, ukuphunyezwa kwekhompyutha- ukuqengqeleka okulawulwayo kwenza ukuqengqeleka kokugqibela emva kokupholisa emva kokupholisa i-laminar (izinga lokupholisa elilawulwa yikhompyutha) kunye ne-coiler, umthamo weenwele ezithe ngqo.Iinwele ezithe ngqo umthamo wentloko, umsila idla ihlwempu, yaba ulwimi-kunye fishtail, ubukhulu, ububanzi, ukuchaneka emphethweni rhoqo kukho amaza-ezimilise, ukusonga, iziphene iphiramidi.Ikhoyili ubunzima ubunzima coil ububanzi 760mm.(Ishishini lombhobho eliqhelekileyo likhetha ukusebenzisa.) Umthamo weenwele ezithe ngqo ngentloko yokusika, ukusika umsila, ukunqumla, kunye ne-multi-pass straightening flat finishing line treatment, ibhodi yokusika okanye umthamo onzima, oko kukuthi, ukuba: ipleyiti yensimbi eshushu. , iikhoyili zetsimbi ezishushu ezishushu, ukunqunqa kunye nezinye iimveliso.Khonza ivolumu yokugqiba eshushu ihlanjululwe, i-pickled kunye ne-oiled hot-rolled pickled coils.

Intsimbi eyenziwe ebandayo
Ingqele eyenziweyo ifana nemathiriyeli ekrwada, emva kokususwa kweoksidi ngokuchola i-tandem ebandayo eyenziwe yagqitywa ukuqengqeleka nzima, umsebenzi uqina ngenxa yomthamo wokuqengqeleka nzima ngenxa yokuqina okubandayo okuguquguqukayo, ukunyuka kokuqina, iimpawu zePlastiki ezinzima ziye zala, ukusebenza kwesitampu kuya kuhla. , kwaye ingasetyenziselwa kuphela ukuguqulwa okulula kwamalungu.Rolling hard roll ingasetyenziswa njengento ekrwada yeplanti yokugalela idiphu eshushu, idiphu eshushu igalelwe umgca wokugalela.Ubunzima bobunzima obuqengqelekayo buziitoni ezi-6 ukuya kwi-13.5, ububanzi bekhoyili bungama-610mm.Izixhobo zokusila zokusila ezibandayo ngokubanzi, umthamo kufuneka ugqithe kwi-continuous annealing (iyunithi yeCAPL) ukuphelisa ukuqina okubandayo kunye noxinzelelo lokuqengqeleka, okanye ukufakwa kwebhetshi kufikelele kwiimpawu zomatshini zomgangatho ohambelanayo ochaziweyo.Icwecwe elipholileyo elenziwe ngentsimbi esemgangathweni, inkangeleko, ukuchaneka komgangatho ongaphezulu kwephepha eliqengqelekayo elishushu, kunye nokuqengqeleka ngasekunene kwemveliso ebhityileyo ukuya kuthi ga kwi-0.18mm.

Umahluko phakathi kwe-hot-rolled kunye ne-cold-formed:
I-1, intsimbi epholileyo epholileyo ukuvumela i-cross-section a buckling yendawo, enokuthi isebenzise ngokupheleleyo intonga ye-buckling bearing umthamo;
I-2, uxinzelelo olushiyekileyo lwentsimbi eshushu kunye nentsimbi eyenziwe ngokubanda eyenziwe ngezizathu ezahlukeneyo, ngoko ke ukuhanjiswa kwecandelo lomnqamlezo kuhluke kakhulu.Ukuhanjiswa koxinzelelo olushiyekileyo kwicandelo elinqamlezayo lokugoba kwentsimbi epholileyo, ukusabalalisa uxinzelelo oluseleyo kwintsimbi eshushu okanye i-welded steel cross-section luhlobo lwefilimu.
I-3 yamahhala ye-torsional stiffness ye-hot-rolled steel, insimbi eyenziwe ngokubanda, i-torsional properties yensimbi eshushu ingcono kunentsimbi epholileyo.
