Zeziphi ezi ntlobo zintathu zeeMila eziqengqelekayo? Isikhokelo sokuKhuthaza ukuFaneka kweMveliso yeMetal

Phakathi kwabo,amatye okungqushaubukhulu becala beza ngeendlela ezintathu: ilitye lokusila eliphakamileyo "elingabuyi-umva", ilitye lokusila elinobude obuphindwe kabini, kunye nelitye lokusila elinobude obuthathu. Olu yilo lubonisa indaleko yobunjineli; uhlobo ngalunye olulandelayo lwaphuhliswa ukoyisa imida yemveliso yomanduleli walo ngokuphucula indlela imathiriyeli ecutshungulwa ngayo phakathi kokudlula okuqengqelekayo.

Ukukhetha ulungelelwaniso oluthile lwelitye lokusila alunamkhethe; imele ukurhweba ngokuthe ngqo phakathi kokulula koomatshini, iindleko zokusebenza, kunye nokusebenza kakuhle kwemveliso. Ukuqonda olu yilo lubonisa umceli mngeni osisiseko wokuqengqeleka kwesinyithi: ukugqiba iipasile ezininzi zokunciphisa ngokukhawuleza.

Uqwalaselo oluSisiseko lweMill Rolling

Ii-rolling Mills zihlelwa ngokusekelwe kwinani kunye nokuhlelwa kwemiqulu yazo. Olu qwalaselo luyalela iilitye lokusilaUkuhamba komsebenzi, isantya, kunye nempumelelo iyonke.

Ezimbini-eziPhezulu "ezingabuyi umva" Mill

● Olu lolona yilo lulula noludala, oluquka imiqulu emibini exhonywe ngokuthe tye ejikeleza kwicala elinye, elingagungqiyo.

● I-workpiece idlula phakathi kwemiqulu kwicala elinye ukunciphisa ubukhulu bayo. Ukwenza enye i-rolling pass, izinto eziphathekayo kufuneka ziphakanyiswe ngokwenyama kwaye zibuyiselwe ngaphaya komqulu ophezulu ukuya kwicala lokungena-inkqubo eyaziwa ngokuba yi "non-reversing" (okanye "lift-over").

● Olu yilo luphawulwa ngokulula kwalo; nangona kunjalo, imveliso yayo iphantsi kakhulu ngenxa yexesha elibalulekileyo kunye nomsebenzi wezandla ofunekayo ukubuyisela i-workpiece yokupasa okulandelayo.

I-Two-High Reversing Mill

● Ukujongana nokungasebenzi kakuhle kwesingqusho esingaguqukiyo, kwaphuhliswa isingqusho esibuyisela umva. Ikwasebenzisa imiqulu emibini, kodwa ukusungulwa kwayo okuphambili ilele kwinkqubo yokuqhuba ekwaziyo ukubuyisela umva indlela yokujikeleza.

● Emva kokuba loo nto idlula kwicala elinye, imiqulu iyama ize ijike. Umsebenzi ke udlula kwakhona kwelinye icala ukuya kwelinye ipasi lokucutha.

● Oku kuphelisa imfuno yokuphatha ngesandla phakathi kokupasa, ukunyusa kakhulu imveliso kunye nokudala ukuhamba komsebenzi okuqhubekayo kwisiqwenga esinye sesixhobo.

I-Three-High Mill

● Ilitye lokusila elinobude obuthathu limela esinye isisombululo esinobuchule kumngeni ofanayo wemveliso. Iqulathe imiqulu emithathu ebekwe ngokuthe nkqo. Imiqulu ephezulu kunye nesezantsi ijikeleza kwicala elinye, ngelixa i-middle roll ijikeleza kwelinye icala.

● I-workpiece idlula isithuba phakathi kweeroli ezisezantsi neziphakathi. Emva koko, itafile yokuphakamisa iphakamisa i-workpiece kwi-gap ephezulu, apho idlula khona kwakhona-ngeli xesha phakathi kwe-middle and top rolls.

● Olu luyilo luvumela ukuqengqeleka okuqhubekekayo kuwo omabini amacala ngaphandle kwesidingo sokubuyisela umva umva oomatshini abanzima, abakhulu, ngaloo ndlela kuzisa umbane ophezulu ngesantya esingaguqukiyo semoto.

Ukuqonda uRhwebo

Ubumbeko ngalunye lunika uluhlu olwahlukileyo lweenzuzo kunye nezingeloncedo. Olona khetho lufanelekileyo luxhomekeke ngokupheleleyo kwiinjongo zakho zemveliso.

Ubulula vs. Imveliso

● Ilitye lokusila elingaguqukiyo elinemiqulu emibini libonisa ulwakhiwo olulula lomatshini kunye neendleko zokuqala eziphantsi. Nangona kunjalo, ukuveliswa kwayo kulinganiselwe kakhulu ngenxa yemfuneko yokuphatha ngesandla, okwenza ukuba ifaneleke kuphela kwimisebenzi encinci okanye ekhethekileyo.

● Ngokwahlukileyo koko, i-two-roll reversing mill kunye ne-three-roll iyilelwe ukuveliswa kwevolumu ephezulu. Ukuntsokotha kwabo okonyuka koomatshini kunye neendleko eziphezulu zithetheleleka kukwanda okukhulu kwemveliso ababonelela ngayo.

Ukuntsokotha koomatshini vs. Ukuntsokotha kokuSebenza

● Ilitye lokusila elijika kabini lifuna imotor enamandla, ekhethekileyo kunye nenkqubo yokulawula ekwaziyo ukubuyisela umva ngokukhawuleza nangokuphindaphindiweyo phantsi kwemithwalo enzima. Oku kongeza kubunzima bombane kunye neenkqubo zokulawula.

● Isixhobo sokusila esiziibhulu ezintathu sisebenzisa inkqubo yokuqhuba elula nengathanga ngqo kodwa ifuna inkqubo yomatshini eyahlukileyo—ngokukodwa itafile yokunyusela—ukuze kudluliselwe izinto ezinzima phakathi kwezikhewu ezisezantsi nezingaphezulu. Oku kwandisa ubunzima bomatshini obunxulumene nokuphathwa kwezinto.

Inkqubo vs. Uqwalaselo (Hot Rolling vs. Cold Rolling)

● Kubalulekile ukwahlula phakathi kobume belitye lokusila (umzekelo, i-two-roll okanye i-three-roll) kunye nenkqubo yokuqengqeleka ngokwayo (i-hot rolling okanye ebandayo).

● Ukuqengqeleka okushushu kwenziwa ngaphezu kweqondo lobushushu bentsimbi ukufezekisa utshintsho olubalulekileyo kwimilo, kanti ukuqengqeleka okubandayo kuqhutywa kwiqondo lobushushu begumbi ukomeleza amandla nokuphucula umphezulu. Naluphi na kolu lungelelwaniso lwelitye lokusila lunokuyilwa ukuze lusetyenziswe ekuqengqelekeni okushushu okanye kwizicelo zokuqengqeleka ezibandayo.

Ukwenza Ukhetho Olululo kwiinjongo Zakho

Ukukhetha ilitye lokusila elililo ngumbandela wokulungelelanisa izakhono zesixhobo kunye neemfuno zakho zokuvelisa.

● Ukuba eyona nto ugxininise kuyo kukulula, imveliso yeebhetshi ezincinci, okanye umsebenzi okhethekileyo: Ilitye lokusila le-"non-reversing" elinee-roli ezimbini limele esona sisombululo sineendleko eziphezulu ngenxa yobulula boomatshini.

● Ukuba ugxininiso lwakho oluphambili luphezulu lwevolyum, imveliso eqhubekayo: I-three-roll mill inika i-output ekhethekileyo ngaphandle kwesidingo senkqubo yokubuyisela umva, iyenza ibe lihashe eliqinileyo nelithembekileyo. 

Ukuba ugxininiso lwakho oluphambili kukuguquguquka okukhulu kunye nomgangatho ophezulu wemveliso, ilitye lokusila eliphindwe kabini linikezela ukuguquguquka okukhulu kwiishedyuli ezahlukeneyo zokunciphisa kwaye ngokuqhelekileyo kulula ukuzenzela kunenkqubo ephezulu emithathu enetafile yokuphakamisa.

Ekugqibeleni, ukuqonda olu yilo lusisiseko linyathelo lokuqala lokuphucula nayiphi na inkqubo yokwenza isinyithi ukufezekisa ulungelelwaniso olufanelekileyo lweendleko, isantya kunye nomgangatho.
