Kuyini i-Hot Rolled Coil?

Ikhoyili Egoqiwe EshisayoUmkhiqizi, Umnikazi Wezabelo,Umhlinzeki we-HRC,Ikhoyili Egoqiwe EshisayoUmthumeli-ngaphandleI-CHINA.

1. ISINGENISO ESIJWAYELEKILE SE-HOT ROLLED COIL

Insimbi egoqiwe eshisayouhlobo lwensimbi olwakhiwa kusetshenziswa inqubo yokugoqa eshisayo ekushiseni okungaphezu kokushisa kwayo kokuphinda isetshenziswe. Insimbi kulula ukuyibumba kuleli zinga lokushisa eliphakeme. Uma kuqhathaniswa nensimbi egoqekile ebandayo, insimbi egoqekile eshisayo ngokuvamile ayidingi ukwelashwa kokushisa ngemuva kokwakheka. Insimbi egoqekile eshisayo ivame ukuba nesilinganiso esikhulu sokugaya kunensimbi egoqekile ebandayo. Ukugoqa okushisayo ngokuvamile kuyindlela eshibhile yokwakha insimbi ngoba izinyathelo ezengeziwe ezidingwa yinsimbi egoqekile ebandayo, njengokufaka i-annealing, ziyagwenywa.

2.UKUSETSHENZISWA KWEIKHOYILI EGQIKIWE NGOKUSHISA

I-roll yensimbi enobukhulu obungu-4 - 8 mm ingasetshenziswa ekwenzeni ukuqinisa, okuhloswe ukuqinisa izakhiwo zekhonkrithi nemikhiqizo. Izinto ezinobukhulu obungu-2-4 mm zisetshenziselwa ukukhiqiza imichilo enamafutha egoqwe ngokushisa, lapho kwenziwa khona igridi ehlukile, amakhona ayizinto ezisizayo ekwakhiweni kwebhodi eligoqiwe, i-siding yensimbi, amaphaneli esandwich odonga nophahla.

3.UKUKHIQIZWA KWE-HOT ROLLED COIL

Ukukhiqizwa kweamakhoyili asongwe ngokushisakuhilela ukusetshenziswa kwensimbi yezinhlobo ezimbili ezahlukene - ejwayelekile yenhloso ejwayelekile kanye nekhabhoni yekhwalithi ephezulu. Ngakho-ke: exutshwe kancane kanye nexutshwe kakhulu. Ukukhiqizwa kwale nto kwenziwa ezigayweni zokugoqa amashidi kusetshenziswa indlela yokugoqa eshisayo ngokugoqa okwengeziwe emqulwini, kugcinwa zonke izindinganiso zikahulumeni. Isici esibalulekile sekhoyili egoqwe eshisayo ukunemba kokugoqa okuhlukaniswe ngezigaba ezimbili: okwandisiwe (A), okuvamile (B).

Izinto ezintsha ezisunguliwe ekukhiqizweni kweikhoyili egoqiwe eshisayozenzelwe ukuhlinzeka ngezinga elidingekayo lezakhiwo zemishini kanye nekhwalithi ephezulu yensimbi egoqwe ngokushisa ekukhiqizweni kwemicu egoqwe ngokushisa ebanzi. Lokhu kusungulwa kuhlobene nokukhiqizwa kokugoqwa futhi kungasetshenziswa ekukhiqizweni kwemicu egoqwe ngokushisa ebanzi ikakhulukazi amamaki ensimbi yamapayipi. Le ndlela ifaka phakathi ukushisa i-slab yokugoqwa ngokushisa, ukuyigoqa emaqenjini aqhubekayo aqinile futhi aqedayo e-broadband mill, ukupholisa okuhlukile kwe-strip ngamanzi kusuka phezulu naphansi ngezingxenye zedivayisi ehlukanisayo ezikhaleni eziphakathi kweqembu lokuqeda le-mill kanye netafula le-outlet roller ngokugoqwa okulandelayo kwe-strip kube yi-roll. Ukwakheka kwemikhiqizo enamandla aphezulu, izakhiwo zepulasitiki, ngaphandle kokwakheka kwemifantu ephambene enkambisweni yokuguqulwa kuqinisekiswa iqiniso lokuthi izinga lokushisa elibekiwe lokuphela kokugoqwa kwemicu enobukhulu obungu-16.1 mm kuya ku-17mm lingu-770-810 ° С, emicu engaphezu kuka-17, 1 mm kuya ku-18.7 mm – 750-790 ° C.

Ububi bezindlela ezaziwayo ekukhiqizweni kwe-hot rolled coil ubunzima bokunikeza izinga elidingekayo lezakhiwo zemishini ze-hot-rolled strips kanye nekhwalithi yobuso ngokusebenza okuphezulu kwe-wide-strip hot rolling mill, ikakhulukazi lapho kukhiqizwa i-thick strips enobukhulu obungu-16 mm noma ngaphezulu.

4.Izici zeIkhoyili Egoqiwe Eshisayo

Ama-coil ashisiwe ashisayo angcono asetshenziswe ezindaweni ezingadingi ushintsho olukhulu lwesimo namandla. Lokhu akusebenziswa nje kuphela ezakhiweni; ama-coil ashisiwe avame ukuthandwa ngamapayipi, izimoto, izitimela, ukwakha imikhumbi njll. Ngesikhathi kwenziwa ama-coil ashisiwe ashisayo; okokuqala insimbi igaywa ekushiseni okuphezulu. Bese insimbi encibilikisiwe iphonswa ku-slab yensimbi bese iphonswa ku-coil. Ngemva kwale nqubo, ama-coil ashisiwe ashisayo kudingeka apholiswe ukuze asetshenziswe. Abakhiqizi basebenzisa kakhulu ubuchwepheshe besimanje enkambisweni yokupholisa behlose ukugwema ukushwabana kwensimbi, okungase kuholele ekungaphelelini kobukhulu be-coil. Lokho kungapheleli kuthinta amanani e-coil ashisiwe ashisayo ngendlela embi futhi kungadala izinkinga nomthengi, onelungelo lokufaka isimangalo. Ama-coil ashisiwe ashisayo akudingeki abe namaphutha ngokubonakalayo ekusebenziseni futhi ngenkathi kunqunywa intengo ye-coil yehora lesi sici siyacatshangelwa.
