Umehluko phakathi komugqa wensimbi ogoqiwe oshisayo kanye nomugqa wensimbi ogoqiwe obandayo

(1) ipuleti lensimbi eligoqiwe elibandayo ngenxa yezinga elithile lokuqina komsebenzi, ukuqina kuphansi, kodwa lingafinyelela isilinganiso esingcono samandla aguquguqukayo, esisetshenziselwa ukugoba okubandayo ishidi lasentwasahlobo nezinye izingxenye.

(2) ipuleti elibandayo lisebenzisa indawo ebandayo egoqiwe ngaphandle kwesikhumba esifakwe oxidized, ikhwalithi enhle. Ipuleti lensimbi eligoqiwe elishisayo lisebenzisa isikhumba se-hot roll rolling surface oxide, ukujiya kwepuleti kunomehluko.

(3) ukuqina kwepuleti lensimbi eligoqiwe elishisayo kanye nokucaba kwendawo akulungile, intengo iphansi, kuyilapho ipuleti eligoqiwe elibandayo linwebeka kahle, liqinile, kodwa libiza kakhulu.

(4) ukuginqika kuhlukaniswe ipuleti lensimbi elibandayo eligoqiwe nelishisayo, elinokushisa okukhazimulayo njengephuzu lokuhlukanisa.

(5) Ukugoqa okubandayo: ukugoqa okubandayo kusetshenziswa ngokuvamile ekukhiqizeni umucu, isivinini sawo sokugoqa siphezulu. Ipuleti lensimbi eligoqiwe elishisayo: izinga lokushisa lokugoqa elishisayo lifana nele-forging.

(6) Ingaphezulu lepuleti lensimbi eligoqiwe elishisayo ngaphandle kokupulekwa liba nsundu ngokumnyama, ingaphezulu lensimbi egoqiwe ebandayo ngaphandle kokucwecwa liba mpunga, futhi ngemva kokucwecwa, lingahlukaniswa nobushelelezi bendawo, ephakeme kunaleyo eshisayo. ipuleti lensimbi eligoqiwe.

umugqa wensimbi ogoqiwe obandayoIncazelo yomucu wensimbi ogoqiwe oshisayo

Ububanzi bomugqa ogoqelwe ngokushisayo bungaphansi noma bulingana no-600mm, ugqinsi lwepuleti lensimbi elingu-0.35-200mm nogqinsi 1.2-25mm umucu wensimbi.

I-Hot Rolled Strip Market Positioning kanye Nokuqondisa Kwentuthuko

Insimbi egoqiwe eshisayo ingenye yezinhlobo eziyinhloko zemikhiqizo yensimbi, esetshenziswa kakhulu embonini, ezolimo, ezokuthutha kanye nokwakhiwa, futhi ngesikhathi esifanayo njengepayipi elibandayo eligoqiwe, elishiselwe, insimbi eyakhiwe ngamakhaza nezinye izinto zokusetshenziswa zokukhiqizwa kwayo. okukhipha eChina ngonyaka wensimbi enani eliphelele lengxenye enkulu yendima eyinhloko ekukhiqizeni insimbi egoqiwe.

Emazweni athuthukile ezimbonini, amapuleti ashisayo agingqiwe kanye nensimbi eyi-strip kubale cishe amaphesenti angama-80 engqikithi yomkhiqizo wepuleti nensimbi ye-strip, okubalwa ngaphezu kwamaphesenti angama-50 engqikithi yokukhiqizwa kwensimbi, kanye nasemqhudelwaneni wezimakethe zamazwe ngamazwe endaweni ehamba phambili.

E-China, imikhiqizo yensimbi evamile egoqelwe ngokushisayo, umkhawulo ophansi wogqinsi ongu-1.8mm, kodwa empeleni, bambalwa kakhulu abakhiqizi okwamanje abakhiqiza insimbi egoqelwe eshisayo enogqinsi olungaphansi kuka-2.0mm, ngisho noma umugqa omncane. , ubukhulu bomkhiqizo ngokuvamile bukhulu kuno-2.5mm.

Ngakho-ke, ingxenye enkulu yethemba lokuthi ukujiya komugqa ongaphansi kuka-2mm njengabasebenzisi bempahla eluhlaza, kufanele kusetshenziswe umucu ogoqiwe obandayo.

I-Cold Rolling Strip

Cold rolled steel strip: metal in the lokushisa recrystallization ngaphansi deformation rolling ibizwa ngokuthi abandayo rolling, ngokuvamile libhekisela strip is hhayi ukushisisa futhi ekamelweni lokushisa inqubo eqondile rolling. Umugqa obandayo ogoqiwe ungase ushise uma uthintwa, kodwa usabizwa ngokuthi ukugoqwa okubandayo.

Ukukhiqizwa okugoqiwe okubandayo kunganikeza inani elikhulu lokunemba okuphezulu nokusebenza okuhle kakhulu kwepuleti lensimbi ne-strip, isici salo esibaluleke kakhulu izinga lokushisa eliphansi lokucubungula, uma kuqhathaniswa nokukhiqizwa kokugoqa okushisayo, kunezinzuzo ezilandelayo:

(1) Imikhiqizo yemigqa egoqelwe ebandayo inemba ngosayizi futhi iyunifomu ngokuqina, futhi umehluko ekujikeni komcu ngokuvamile awubi ngaphezu kuka-0.01-0.03mm noma ngaphansi, ongahlangabezana ngokugcwele nezidingo zokubekezelela okunembayo okuphezulu.

(2) Imichilo emincane kakhulu engakwazi ukukhiqizwa ngokugoqeka okushisayo ingatholakala (encane kakhulu ingaba ngu-0.001mm noma ngaphansi).

(3) Izinga elingaphezulu lemikhiqizo egoqiwe ebandayo liphakeme, awukho umucu ogoqiwe oshisayo ovame ukubonakala ugoba, ucindezelwe ku-iron oxide nokunye ukukhubazeka, futhi ungakhiqizwa ngokuya ngezidingo zomsebenzisi zokuma okuhlukile komugqa (ocwebezelayo). indawo engaphezulu noma enemigodi, njll.), ukuze kube lula ukucutshungulwa kwenqubo elandelayo.

(4) Insimbi egoqelwe ebandayo inezimfanelo ezinhle kakhulu zemishini kanye nezakhiwo zenqubo (njengamandla aphezulu, umkhawulo wesivuno esiphansi, ukusebenza kahle komdwebo ojulile, njll.).

(5) Ukuginqika okunesivinini esikhulu nokugingqika okugcwele okuqhubekayo kungenziwa, ngokukhiqiza okuphezulu.

Ukuhlukaniswa kwensimbi egoqiwe ebandayo

Cold roll roll steel ihlukaniswe yaba izinhlobo ezimbili: black and bright.

(1) umucu omnyama ogoqiwe: umucu ogoqiwe obandayo ushisiswe ngokuqondile kuzinga lokushisa lokudonsa, umbala ongaphezulu ngenxa yokuchayeka kwezinga lokushisa eliphezulu kumnyama womoya. Izakhiwo ezibonakalayo ziyathamba, zivame ukusetshenziselwa umugqa wensimbi bese kuthi ingcindezi enwetshiwe, isitembu, ukuwohloka kokucubungula okukhulu okujulile.

(2) i-anealed strip ekhanyayo: futhi emnyama i-annealed umehluko omkhulu ukuthi ukushisisa akuthintani nomoya, i-nitrogen namanye amagesi angenayo avikelekile, umbala ongaphezulu okufanele ugcinwe kanye nomugqa ogoqekayo obandayo, ngaphezu kokumnyama okufakwe emanzini. ukusetshenziswa nakho kusetshenziselwa ingaphezulu le-nickel plating nezinye izindlela zokwelapha ezingaphezulu, ezinhle futhi eziphanayo.

Insimbi yomugqa ogqamile kanye nomehluko wensimbi womugqa omnyama obunayo: izici zokulungisa zicishe zifane, insimbi yomugqa ogqamile ikunsimbi emnyama efiphalayo ngesisekelo sesinyathelo esingaphezu kwesisodwa sokwelashwa okukhanyayo.

Ukusetshenziswa: insimbi emnyama efiphalayo ngokuvamile yenziwa imikhiqizo yokugcina ngaphambi kokuthi ilunge ukuze kwenziwe ukwelashwa kwe-landscaping, insimbi yomugqa okhanyayo ingagxivizwa ngokuqondile emikhiqizweni yokugcina.

Uhlolojikelele lokuthuthukiswa kokukhiqizwa kwensimbi ebandayo

Ubuchwepheshe bokukhiqiza i-cold rolled strip kuwuphawu olubalulekile lwezinga lokuthuthuka kwemboni yensimbi. Ipuleti lensimbi elincanyana lemoto, imishini yezolimo, imboni yamakhemikhali, ukuthunga ukudla, ukwakhiwa, izinto zikagesi nokunye ukusetshenziswa kwezimboni, kodwa futhi linobudlelwano obuqondile nempilo yansuku zonke, njengeziqandisi zasendlini, imishini yokuwasha, amathelevishini nezinye izidingo zepuleti lensimbi elincanyana. . Ngakho-ke, kwamanye amazwe athuthukile ezimbonini, ipuleti lensimbi elincanyana libalwa njengengxenye yensimbi ekhuphuka unyaka nonyaka, epuletini elincanyana, i-strip steel, i-akhawunti yemikhiqizo egoqwe ebandayo ingxenye enkulu.
