Zeziphi Iindidi zeMiqulu ekhoyo?

Ngokwendlela yokubumba: Imiqulu yokuphosa kunye nemiqulu eyenziweyo.

Iyaphosaimiqulubhekisa kwiintlobo zemiqulu eyenziwe ngokutyhilwa ngokuthe ngqo kwentsimbi enyityilisiweyo okanye isinyithi esinyibilikisiweyo.

Imiqulu yokuphosa inokwahlulwa ibe ngamacandelo amabini: imiqulu yensimbi ephosiweyo kunye nemiqulu yentsimbi ephoswe ngokwezinto;ngokweendlela zokuvelisa, zinokwahlulwa zibe ngamacandelo amabini: imiqulu yokugalela edityanisiweyo kunye nemiqulu edibeneyo yokuphosa.

I-Forging rolls ihlelwa ngokwezinto ezibonakalayo ngolu hlobo lulandelayo:

(1) Imiqulu yentsimbi yokubumba;

(2) Ukwenza imiqulu yentsimbi engangentsimbi;

(3) Ukwenza imiqulu yentsimbi enesantya esiphezulu;

(4) Imiqulu yentsimbi ebunjiweyo emhlophe.

Ngokwendlela yenkqubo:Imiqulu edibeneyo, i-metallurgical composite rolls kwaye idibeneimiqulu.

1. Xa kuthelekiswa nomqulu odibeneyo, umqulu jikelele uphonswa okanye uphonswe kunye nesixhobo esisodwa soluhlu lwangaphandle, ingundoqo kunye nentamo yomqulu jikelele.Umaleko wangaphandle umqulu umzimba kunye nentamo zinezakhiwo ezahlukeneyo kunye neepropati ngokuphosa okanye inkqubo Forging kunye nenkqubo yonyango ubushushu ukulawula nokulungelelanisa.Zombini iiroli ezibunjiweyo kunye neeroli ezimile ziyimiqulu edityanisiweyo.Imiqulu edityanisiweyo yahlulwe yaba yi-integral casting kunye nemiqulu edibeneyo yokubumba.

2. Imiqulu yokujula edityanisiweyo ye-Metallurgical ibandakanya ikakhulu ukugungxulwa komdibaniso we-semi-gung, ukuphuphuma (ugungxulo olupheleleyo) ukuphosa okudityanisiweyo, kunye ne-centrifugal composite casting.Iintlobo zemiqulu edibeneyo eyenziwe ngeendlela ezikhethekileyo ezidibeneyo ezifana ne-isostatic pressing (HIP-Hot Isostatically Pressed) kunye ne-electroslag welding.Uluhlu oludibeneyo luyi-set of rolls ezidibeneyo.

Ngokwenza izinto:

Cast metal series rolls, cast iron series rolls and forged series rolls

Iindidi ezisetyenziswa ngokuqhelekileyo zonyango lobushushu kwimiqulu: i-stress annealing, isothermal spheroidizing annealing, diffusion annealing, normalizing, tempering, quenching, unyango lwe-cryogenic.

Ngokobume bomzimba womqulu:

Kukho iindlela ezahlukeneyo zokuhlela imiqulu.Ngokwesimo somzimba we-roll, ihlukaniswe ibe yi-cylindrical kunye ne-non-cylindrical, yangaphambili isetyenziselwa ukuveliswa kwamacwecwe, imichilo, iiprofayili kunye neengcingo, kwaye le yokugqibela isetyenziselwa ukuveliswa kwemibhobho.

Ngokuhambelana nokuba idibene neqhekeza eliqengqelekayo:

Yahlulahlulwe yaba yimiqulu yomsebenzi kunye nemiqulu yokugcina.Imiqulu edibana ngokuthe ngqo ne-rolling stock ibizwa ngokuba yimiqulu yomsebenzi;imiqulu ebekwe ngasemva okanye kwicala lemiqulu yomsebenzi ngaphandle kokuqhagamshelana ngokuthe ngqo ne-stock rolling ukunyusa ukuqina kunye namandla emisebenzi ebizwa ngokuba yi-backup rolls.

Ngokusetyenziswa kwe-rack:

Ngokusetyenziswa kokuma, ihlulwe ibe yimiqulu eqhakaza, i-roughing rolls, i-intermediate rolls kunye nemiqulu yokugqiba.Ngokweentlobo zezixhobo zokuqengqeleka, yahlulwe yaba yimiqulu ye-strip, imiqulu kaloliwe kaloliwe, imiqulu yeentambo zocingo kunye nemiqulu yombhobho.Isenokwahlulwa ibe yimiqulu eshushu kunye nemiqulu ebandayo ngokwemeko ye-rolling stock ngexesha lokuqengqeleka.

Ngokwexabiso lobulukhuni:

(1) I-Soft rolls Ubunzima be-Shore bu malunga ne-30 ~ 40, esetyenziselwa ukucoca oomatshini, i-rough rolling mill yecandelo elikhulu lentsimbi, njl.

(2) Ii-semi-hard rolls Ukuqina konxweme kumalunga ne-40 ~ 60, kusetyenziselwa ukungqusha okurhabaxa okuqengqelekayo kwecandelo elikhulu, eliphakathi kunye nelincinci lokusila intsimbi kunye neepleyiti zentsimbi.

(3) Iiroli ezinobuso obunzima Ukuqina konxweme kumalunga ne-60 ~ 85, esetyenziselwa ukungquba okurhabaxa kwepleyiti ebhityileyo, ipleyiti ephakathi, intsimbi yecandelo eliphakathi kunye necandelo elincinci lentsimbi yokusila kunye neeroli ezigcinayo ezine eziphakamileyo zokusila.

Ngokohlobo lweilitye lokusila:

(1) Umqulu osicaba.Nantso keIiRolling Mill, i-roll body is cylindrical.Ngokuqhelekileyo, imiqulu yentsimbi eshushu-eshushu iyenziwa ibe yimo encinci ye-concave, kwaye xa ishushu kwaye yandiswa, i-shape engcono inokufumaneka;Imiqulu yentsimbi epholileyo epholileyo yenziwe ibe yimo encinci ye-convex, kwaye imiqulu igobile ngexesha lokuqengqeleka ukufumana ukumila okulungileyo.

(2) Imiqulu eqingqiweyo.Isetyenziselwa ukuqengqeleka amacandelo amakhulu, aphakathi kunye namancinci, iintonga zocingo kunye nokuqhakaza.I-grooves ibhalwe kumphezulu we-roll ukuze imise isitokhwe esiqengqelekayo.

(3) Imiqulu ekhethekileyo.Isetyenziswa kwii-rolling mills ezikhethekileyo ezifana nombhobho wensimbiamatye okungqusha, ii-wheel rolling mills, iintsimbi zokusila iibhola zentsimbi kunye nezixhobo zokubhoboza.Imiqulu yale mill ejikelezayo ineemilo ezahlukahlukeneyo, njengemiqulu egqitywe ngumgaqo we-skew rolling kwi-rolling pipe yensimbi, eyi-conical, i-drum esinqeni okanye i-disc.
