Izinto eziluncedo kunye nokungonakali kwe-hot rolling

Zomibini i-hot rolling kunye ne-cold rolling ziyinkqubo yokwenza iiplate zetsimbi okanye iiprofayili, kwaye zinempembelelo enkulu kwisakhiwo kunye neempawu zensimbi.

I-rolling yensimbi isekelwe ikakhulu kwi-hot rolling, kwaye i-cold rolling idla ngokusetyenziswa kuphela ukuvelisa isinyithi kunye nemilinganiselo echanekileyo efana nentsimbi yecandelo kunye neshidi.

Ubushushu bokupheliswa kokuqengqeleka okushushu buyi-800~900℃, kwaye ke bupholiswa ngokubanzi emoyeni, ngoko ke imeko yokuqengqeleka eshushu ilingana nonyango oluqhelekileyo.

Uninzi lweentsimbi ziqengqeleka yindlela yokuqengqeleka eshushu.Ngenxa yobushushu obuphezulu, intsimbi ehanjiswa kwindawo eshushu ifakwe kwisikali se-iron oxide esikalini, ngoko inokumelana nokugqwala okuthile kwaye inokugcinwa kwindawo evulekileyo.

Nangona kunjalo, le maleko yesikali se-iron oxide yenza umphezulu wentsimbi eshushu-eqengqelekayo iberhabaxa kwaye nobungakanani buguquguquka kakhulu.Ke ngoko, intsimbi enomgangatho ogudileyo, ubungakanani obuchanekileyo kunye neepropathi ezilungileyo zoomatshini ziyafuneka, kwaye iimveliso ezigqityiweyo ezigqityiweyo okanye iimveliso ezigqityiweyo zisetyenziswa njengezinto ezibonakalayo zokuvelisa okubandayo.

inzuzo:

Isantya sokwenza ngokukhawuleza, isiphumo siphezulu, kwaye isambatho angonakaliswa, kwaye sinokwenziwa kwiifom ezahlukeneyo ze-cross-sectional ukuhlangabezana neemfuno zemiqathango yokusetyenziswa;ukuqengqeleka okubandayo kunokubangela i-deformation enkulu yeplastiki yentsimbi, ngaloo ndlela inyusa indawo yemveliso yentsimbi.

ukusilela:

1. Nangona kungekho ukunyanzeliswa kweplastiki eshushu ngexesha lokuqulunqa, kusekho uxinzelelo oluseleyo kwicandelo, eliya kuchaphazela ngokuqinisekileyo iimpawu ze-buckling jikelele kunye nezendawo zetsimbi;

2. Isitayela sentsimbi yecandelo elibandayo ngokuqhelekileyo licandelo elivulekileyo, elenza ukuqina kwe-torsional yamahhala yecandelo eliphantsi.Iyathandeka kwi-torsion xa iphantsi kokugoba, ithande ukugoba-torsional buckling phantsi koxinzelelo, kwaye inokusebenza kakubi kwe-torsional;

3. Ubunzima bodonga lwentsimbi epholileyo epholileyo luncinci, kwaye aluqiniswanga kwiikona apho amacwecwe adibaniswe khona, kwaye amandla okumelana nemithwalo egxininisiweyo yendawo ibuthathaka.
