Ukukhanya phakathi kwehlango lamanzi amagenge kanye nehlango lokugcwalisa amagenge

(1) I-plate yensimbi ehlanganiswe ngamakhaza ngenxa yezinga elithile lokuqina komsebenzi, ubunzima buphansi, kodwa bungakwazi ukufeza isilinganiso esihle sokuqina kokuqina, esisetshenziselwa ukugoba amakhaza we-spring sheet nezinye izingxenye.

(2) Ipuleti elibandayo elisebenzisa indawo ehlanganiswe ebandayo ngaphandle kwesikhumba esi-oxidized, ikhwalithi enhle. I-plate yensimbi eshisayo eshisayo isebenzisa isikhumba se-oxide sokusebenza esishisayo, ubukhulu beplate bunomehluko.

(3) ukushisa iphuma steel ipuleti ubulukhuni futhi flatness surface libi, intengo lingaphansi, kuyilapho abandayo iphuma ipuleti elula ezinhle, ubulukhuni, kodwa eqolo.

(4) Ukugoqa kuhlukaniswa kube amapuleti wensimbi agingqwe abandayo nagoqwayo ashisayo, lapho izinga lokushisa lokuvuselela kabusha liyinto yokuhlukanisa.

(5) Ukucindezela okugcwetwe: ukucindezela okugcwetwe ngokuvamile kusetyenziswa kwinqanaba lestrip, ukuba kucindezelwa kakhulu. I-steel plate ephathwe ngokugcwetwe: ubukhulu bokugcina kwekucindezela kufana nokugcinwa kwekugcina.

(6) Umbo olungileyo lwephlathu elihlatyelweyo engenakho ingcaciso yemetye libonakala ngokuba yiluhlu oluchangci, umbo olungileyo lwephlathu elincinweyo engenakho ingcaciso yemetye lube ngu-gray, kwaye emva kokuluhlu, kunokwaziwa ngokubonakala kwezinto eziphambene, oku kakhulu kunekucindezelwa okugcwetwe.

isisele seseseli esikhewuneyo

ukucindezela okugcwetwe okanye ukucindezela okugcina

Ububanzi behot-rolled strip ngaphantsi okanye kulingana no-600mm, ubukhulu 0.35-200mm yephlathu kunye nobukhulu be-1.2-25mm yestrip.

Ukusekwa kweHot Rolled Strip kunye nokucoca indlela yokuvuleka

Izinto ezingenakhiwe ngokugcina kanye nezinto zokulula ziyasebenzisa ngokubangelwa kakhulu kumqamatha, ukudlula, ukulawulwa kanye nokubangela, futhi ngokwesibonelo njengokulula okuphansi, izinto ezingenakhiwa ngokugcina, kanye nezinto zokwenza izinto ezingenakhiwa ngokugcina. Oku kwenziwa kakhulu emhlabeni wase China kanye nokuba yisikhali esikhulu sokwenza izinto ezingenakhiwa ngokugcina.

Emhlabeni wemipakati yisimo esiphezulu, izinto ezingenakhiwa ngokugcina kanye nezinto zokulula ziyahlala kakhulu ngaphezu kwe-80% yezinto zokulula, kanye nezinto zokwenza izinto ezingenakhiwa ngokugcina, kanye nezinto zokulula ziyahlala kakhulu ngaphezu kwe-50% yezinto zokwenza izinto ezingenakhiwa ngokugcina, kanye nezinto zokulula ziyahlala kakhulu emhlabeni wemipakati yisimo esiphezulu.

Wase China, izinto ezingenakhiwa ngokugcina kanye nezinto zokulula, okuphansi kweziciro kungenxa yale 1.8mm, kodwa ngempela, kungenxa yale 2.0mm kakhulu amakhampani ambalwa kuphela okwenza izinto ezingenakhiwa ngokugcina kanye nezinto zokulula, noma ukuba yinto encinci, iziciro ziyahlala kakhulu ngaphezu kwe-2.5mm.

Ngakho, inani elikhulu kakhulu lothando abasebenzisa izitimela ezingaphansi kwe 2mm njengamagxekwa, kufanele basebenzise izitimela ezingculwe ngokuchane.

Cold Rolled Strip

Izitimela ezingculwe ngokuchane: ubuchule obugcwele phansi kwenkantolo yokuqala kanye nekantolo yokuqala ekugcwaleni kubizwa ngokuthi izitimela ezingculwe ngokuchane, ngokuvumelana bubelela ukuthi izitimela ayikhanyekwa futhi kugcwala ngokusheshisa. Izingculwe ngokuchane ingaba yishushu, kodwa ishushu sibizwa ngokuthi yingculwe ngokuchane.

Ukuzithutha ngokuchane kungenisa amathimba amakhulu kakhulu wezitimela nezitimela eziphumelelayo, isici esibhekene kakhulu nayo yileyo yokushesha okuphansi, ngokulingana nokuzithutha ngokusheshisa, inemiphakathi lesonke okulandelayo:

(1) Izinhlayiya zokunqanda zokunqanda kanye nezinhlayiya eziphakeme kakhulu zinezobe lekwekwe fokuthi kuzobonakala ukuphakeme kwezinhlayiya, futhi ukuhluka kwepakeme kwezinhlayiya kungenzeka ukuba kungaphansi koma 0.01-0.03mm noma ngaphansi, okungaba yisici esikhulu sokuvumela imiphumela yokuvumela okuphezulu kakhulu.

(2) Izinkinga eziyinkulu kakhulu engazokwelwa ngokugqibekela ngokwephakathi zokuthola (izinkinga eziphakathi kakhulu zingaba yingxenye ka 0.001mm noma ngaphansi).

(3) Imbobo yephepha lekwekwe yekwelwe ngokwephakathi iyinkulu, akukho pitting esiyahlukene nekwekwe elikhulu lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwekwe lekwek......

(4) Istrip yekwelwe ngokwephakathi inemikhiwane eminhle kanye nemigomo yokwenza (njengokukhulu kwezimali, ukunciphisa okuphansi, imicimbi yokwenza emininingwane, njll.).

(5) Kungavela ukugqiba ngokusheshayo nokugqibela konke ngokulandelana, ngekhiya elikhulu.

Ukwekwekwelwa kwekwekwe

Istrip yekwelwe ngokwephakathi iyahlukahluka ezimbini: omnyama noma onqonqo.

(1) umgca ophuziwe: umgca ophuziwe ngokushesha oqinisekisiwe kakhulu kuya kumaphiziyo wokuphuzisa, umbala wokubona ngokungafani nendzima yokuqina kweyohlobo lomgca uphuziwe. Iziphawuli zokubona zizizetha, ngokuvamile isebenziswa kakhulu ngemigca yamandla emuva kokuthiwa, ukucubwa, ukuguqwa kwezindlela eziningi zokwenza ngemibono.

(2) umgca ophuziwe ngokulula: faka kakhulu ukuhlanganisa phakathi kwe umgca ophuziwe ngokushesha ne umgca ophuziwe ngokulula kukukhona kweyohlobo lomgca, ngaphandle kokuthi kuhlangane neyohlobo, kusetyenziselwa i-nitrogen nezinye i-indlela zokupheya, umbala wokubona uqinisekisiwe kuye ne umgca ophuziwe ngokushesha, ngaphandle kokuqina kweyohlobo lomgca, kuyasebenzisa kakhulu kwiindlela zokwenza ngokubona njenge ukubhala ngokubona, ukwenza ngokubona kakhulu, kubonakala ngokulula.

Umgca ophuziwe ngokulula ne umgca ophuziwe ngokushesha ukuhlanganisa: iziphawuli zokusebenza zifana ngokuphelele, umgca ophuziwe ngokulula kukho kakhulu ngokusebenza kwe umgca ophuziwe ngokushesha ngokwesinye isinyathelo sokuphuzisa ngokulula.

Isisebenziso: isiteleni sokumelana esibomvu sikhona kakhulu sisetshenziswa ekwenzeni amaphrothukthu emuva kokuba kufunekile ukwenza ukulahlekelwa kwezimali, isiteleni esibonakalayo singasetshenziswa ngqo ekusethweni endaweni yokuphela.

Ukutholwa kwezimali ezingenakona ukuphansi komoya

Iteknoloji yokulayisha isiteleni esingena ngokuphansi komoya iyisimboli esikhulu sokuphila kwezimali. Iphela ecamancamana yeziteleni esebenzisa kakhulu ekuvuleni, kwezimali zokulandela, kwezimali zokuchitha, kwezimali zokuncamathisa, kwezimali zokubungca, nezimali zokusebenza ngemali, kodwa nazo zinezinkxenye eziphakathi nezinto zethu zasemgangeni, njengokuthi kuzo izinto zokubeka izimoto, izithuthi zokulandela, nezimoto zokulandela. Ngakho, kuzo ezimbini zemali zokutholwa kwezimali, iphela ecamancamana yeziteleni ezingena ngokuphansi komoya iyahlukahluka ngokwezinye, kuleyo iphela, kuzo iziteleni, nezinto ezitholakale ngokuphansi komoya.
