Umahluko phakathi kwentsimbi eshushu esongwayo kunye nentsimbi epholileyo

Inkcazo yomgca wentsimbi eshushu

I-Hot-rolled strip ububanzi ngaphantsi okanye ilingana ne-600mm, ubukhulu be-0.35-200mm ipleyiti yentsimbi kunye nobukhulu be-1.2-25mm strip yensimbi.

 

Ukuma kweMarike eQhelekileyo eqengqelekayo kunye neSikhokelo soPhuhliso

 

Intsimbi eshushu eqengqelekayo yenye yeendidi eziphambili zeemveliso zentsimbi, ezisetyenziswa kakhulu kushishino, kwezolimo, kwezothutho kunye nolwakhiwo, kwangaxeshanye njengengqele eqengqelekayo,umbhobho odityanisiweyo, intsimbi epholileyo eyenziwe ngentsimbi kunye nezinye izinto eziluhlaza zokuvelisa imveliso yayo kwimveliso yonyaka yentsimbi yaseChina kwisixa esipheleleyo somlinganiselo omkhulu wendima ephambili kwimveliso yentsimbi eqengqelekayo.

Kumazwe aphuhlileyo kwimizi-mveliso,ipleyiti esongwe eshushukunye nentsimbi yentsimbi ibalwa malunga ne-80% yesiphumo esipheleleyo seplate kunye nentsimbi yentsimbi, ibala ngaphezu kwe-50% yemveliso yentsimbi epheleleyo, kunye nokhuphiswano lwemarike yamazwe ngamazwe kwindawo ehamba phambili.

E-China, iimveliso zentsimbi ezishushu eziqengqelekayo, umda osezantsi wobunzima be-1.8mm, kodwa enyanisweni, bambalwa kakhulu abavelisi okwangoku abavelisa intsimbi eshushu eqengqelekayo enobunzima obungaphantsi kwe-2.0mm, nokuba umtya omxinwa. , ubukhulu bemveliso bukhulu kune-2.5mm.

Ke ngoko, inxalenye enkulu yethemba lokuba ubukhulu obungaphantsi kwe-2mm strip njengabasebenzisi bemathiriyeli ekrwada, kufuneka basebenzise umcu oqengqelekayo obandayo.

 

I-Cold Rolling Strip

Cold rolled steel strip: intsimbi kwiqondo lobushushu recrystallization ngezantsi deformation rolling kuthiwa kubanda rolling, ngokubanzi ibhekisela strip ayishushu kwaye kubushushu begumbi inkqubo ngqo rolling. Umcu obandayo oqengqelekayo usenokuba shushu xa uwubamba, kodwa usabizwa ngokuba ngumqengqeleki obandayo.

Imveliso epholileyo eqengqelekayo inokubonelela ngenani elikhulu lokuchaneka okuphezulu kunye nokusebenza okugqwesileyo kwepleyiti yentsimbi kunye nomcu, eyona nto ibaluleke kakhulu kubushushu bokusebenza obuphantsi, xa kuthelekiswa nemveliso eshushu yokuqengqeleka, inezi zinzuzo zilandelayo:

(1) Iimveliso zemicu epholileyo zichanekile ngokobukhulu kunye nobukhulu obufanayo, kwaye umahluko kubukhulu bomtya awukho ngaphezulu kwe-0.01-0.03mm okanye ngaphantsi, onokuhlangabezana ngokupheleleyo neemfuno zonyamezelo oluchanekileyo.

2

3 umphezulu okanye indawo enemingxuma, njl.njl.), ukwenzela ukuba kube lula ukusetyenzwa kwenkqubo elandelayo.

(4) Intsimbi epholileyo eqengqelekayo ineempawu ezintle kakhulu zoomatshini kunye nepropathi yenkqubo (njengamandla aphezulu, umda wesivuno esisezantsi, ukusebenza kakuhle komzobo onzulu, njl. njl.).

(5) Ukuqengqeleka kwesantya esiphezulu kunye nokuqengqeleka okupheleleyo okuqhubekayo kunokufezekiswa, kunye nemveliso ephezulu.

Cold rolling strip steel classification

Intsimbi epholileyo eqengqelekayo yohlulwe ibe ziindidi ezimbini: ezimnyama neziqaqambileyo.

(1)umtya omnyama: Umcu oqengqelekayo obandayo ufudunyezwe ngokuthe ngqo kwiqondo lobushushu le-anneal, umbala womphezulu ngenxa yokuvezwa kobushushu obuphezulu kumnyama womoya. Iipropathi ezibonakalayo ziyathambile, zisetyenziselwa umcu wentsimbi kwaye emva koko uxinzelelo olwandisiweyo, isitampu, ukuguqulwa kokulungiswa okunzulu okukhulu.

(2) icwecwe elikhanyayo: kunye ne-annealed emnyama owona mahluko mkhulu kukuba ukufudumeza akudibanisi nomoya, kunye ne-nitrogen kunye nezinye iigesi ze-inert zikhuselwe, umbala ongaphezulu ukugcina kunye nomcu oqengqelekayo obandayo, ukongeza kusetyenziso olumnyama olufakwe emanzini lukwasetyenziselwa umphezulu womphezulu we-nickel plating kunye nolunye unyango olungaphezulu, oluhle kunye nesisa.

Umcu oqaqambileyo wentsimbi kunye nomehluko wentsimbi otyhafayo omnyama: iipropathi zoomatshini ziphantse zifane, intsimbi eqaqambileyo yentsimbi ikwintsimbi emnyama ecimayo kwisiseko senyathelo elingaphezulu kwesinye lonyango oluqaqambileyo.

Ukusetyenziswa: Intsimbi emnyama efiphalayo iqhele ukwenziwa ibezimveliso zokuphela phambi kokuba kulunge ukwenza unyango oluthile, intsimbi eqaqambileyo inokugximfizwa ngokuthe ngqo kwiimveliso zokugqibela.
