Ngokwendlela yokubumba:Ama-Cast rolls nama-forged rolls.
Iyasakazaimiqulubhekisela ezinhlotsheni zemiqulu ekhiqizwa ngokubunjwa okuqondile kwensimbi encibilikisiwe encibilikisiwe noma insimbi encibilikisiwe.
Ama-casting rolls angahlukaniswa ngezigaba ezimbili: ama-cast steel rolls nama-cast iron rolls ngokuya ngezinto zokwakha;ngokwezindlela zokukhiqiza, zingahlukaniswa zibe izigaba ezimbili: imiqulu yokuphonsa ehlanganisiwe kanye nemiqulu yokuphonsa eyinhlanganisela.
Ama-Forging rolls ahlukaniswa ngezinto ezinjengalezi:
(1) Imiqulu yensimbi yokubumba;
(2) Ukubumba amaroli ensimbi;
(3) Ukwakha amaroli ensimbi anesivinini esikhulu;
(4) Imiqulu yensimbi ebunjiwe emhlophe.
Ngokusho kwendlela yenqubo:Imiqulu ehlanganisiwe, imiqulu eyinhlanganisela ye-metallurgical futhi ihlangeneimiqulu.
1. Uma kuqhathaniswa ne-composite roll, i-overall roll iphonswa noma ihlanganiswe ngento eyodwa yongqimba lwangaphandle, umgogodla kanye nentamo ye-roll jikelele.Isendlalelo sangaphandle somzimba we-roll kanye nentamo inezakhiwo nezakhiwo ezahlukene ngokusebenzisa inqubo yokufaka noma ye-Forging kanye nenqubo yokwelapha ukushisa ukuze ulawule futhi ulungise.Womabili amaroli afojiwe kanye nama-static cast amaroli abalulekile.Imiqulu edidiyelwe ihlukaniswe yaba imiqulu edidiyelwe yokusakazwa kanye nemiqulu yokuhlanganisa.
2. Amaroli okulingisa ayinhlanganisela ye-Metallurgical ikakhulukazi ahlanganisa ukulingwa okuyinhlanganisela okuguquguquka kancane, ukuchichima (ukushisa okugcwele) ukusakaza okuyinhlanganisela, kanye nokusakaza okuyinhlanganisela emaphakathi.Izinhlobo zemiqulu eyinhlanganisela eyenziwe ngezindlela ezikhethekile eziyinhlanganisela ezifana nokucindezela kwe-isostatic (HIP-Hot Isostatic Pressed) kanye ne-electroslag welding.I-roll ehlanganisiwe ngokuyinhloko iqoqo lemiqulu ehlanganisiwe.
Ngokwenza izinto:
Amaroli e-Cast steel series, ama-cast iron series rolls nama-forged series rolls
Izinhlobo ezisetshenziswa kakhulu zokwelapha ukushisa kwamaroli: ukukhishwa kwe-stress annealing, isothermal spheroidizing annealing, diffusion annealing, normalizing, tempering, quenching, treatment cryogenic.
Ngokwesimo somzimba we-roll:
Kunezindlela ezihlukene zokuhlukanisa ama-roll.Ngokusho kokuma komzimba we-roll, ihlukaniswe ibe yi-cylindrical ne-non-cylindrical, eyokuqala isetshenziselwa ukukhiqizwa kwamapuleti, amapheshana, amaphrofayili kanye nezintambo, kanti lena yokugcina isetshenziselwa ukukhiqizwa kwamapayipi.
Ngokuya ngokuthi ingabe ixhumene nocezu olugoqiwe:
Ihlukaniswe yaba imiqulu yomsebenzi kanye nama-backup rolls.Amaroli athintana ngqo nesitoko abizwa ngokuthi ama-work roll;amaroli abekwe ngemuva noma ohlangothini lwemiqulu yomsebenzi ngaphandle kokuxhumana ngokuqondile nesitokwe esigoqayo ukuze kwandiswe ukuqina namandla amaroli okusebenza abizwa ngokuthi ama-backup rolls.
Ngokusebenzisa i-rack:
Ngokusebenzisa i-stand, ihlukaniswe yaba imiqulu eqhakazayo, imiqulu egoqayo, imiqulu ephakathi nendawo kanye nemiqulu yokuqeda.Ngokuya ngezinhlobonhlobo zezinto eziginqikayo, ihlukaniswe yaba ama-strip roll, amaroli we-rail beam, ama-wire rod rolls namapayipi.Ingabuye ihlukaniswe ngama-hot rolls kanye nama-cold rolls ngokuya ngesimo sesitoko esigoqayo ngesikhathi sokugoqa.
Ngokwevelu yobulukhuni:
(1) Amaroli athambile Ukuqina kogu cishe ku-30~40, okusetshenziselwa imishini yokukhipha, izigayo ezigoqayo zezigayo ezinkulu zensimbi, njll.
(2) Izigayo ezisaqinile Ukuqina kosebe cishe kungama-40~60, asetshenziselwa izigayo ezigoqayo zezigayo ezinkulu, ezimaphakathi nezincane zensimbi nezigayo zamapuleti ensimbi.
(3) Amaroli anobuso obuqinile Ukuqina kosebe cishe kungama-60~85, asetshenziselwa izigayo ezigoqayo zepuleti elincanyana, ipuleti eliphakathi nendawo, insimbi yesigaba esimaphakathi kanye nezigayo zensimbi zesigaba esincane kanye namaroli okusekelayo wezigayo ezine-high rolling.
(4) Amaroli aqinile engeziwe Ukuqina kosebe cishe kungama-85~100, asetshenziswa ezigayweni ezibandayo.
Ngokohlobo lweumshini wokugaya:
(1) Umqulu oyisicaba.YilokhoI-Rolling Mill Rolls, umzimba we-roll uyi-cylindrical.Ngokuvamile, imiqulu yensimbi egoqelwe ngokushisayo yenziwa ibe yisimo esigoqe kancane, futhi lapho sishiswa futhi sandiswa, kungatholakala isimo esingcono;imiqulu yensimbi egoqelwe ebandayo yenziwa yaba yisimo esithe ukuconvezela, futhi imiqulu iyagotshwa ngesikhathi iginqika ukuze ibe nokuma okuhle.
(2) Ama-grooved rolls.Isetshenziselwa ukugingqa izingxenye ezinkulu, eziphakathi nezincane, izinduku zocingo nokuqhakaza.Ama-grooves aqoshwa endaweni yomqulu ukuze alolonge isitoko esigoqayo.
(3) Imiqulu ekhethekile.Isetshenziswa ezigayweni ezikhethekile zokugingqa njengepayipi lensimbiizigayo, izigayo ezigingqa amasondo, izigayo zensimbi ezigingqa amabhola kanye nezigayo zokubhoboza.Imiqulu yalesi sigayo esigoqayo inezimo ezihlukahlukene, njengemiqulu egoqwe ngomgomo wokugoqa i-skew ku-rolling yepayipi yensimbi, eyi-conical, i-waist drum noma i-disc.
