Izingqusho eziqengqelekayoidlala indima ebalulekileyo kwishishini lemveliso, ukuguqula izinto eziluhlaza zibe ziintlobo ezahlukeneyo zeemveliso zentsimbi. Okusembindini wokusebenza komatshini wokungqusha zeziimiqulu, ezijongene nokubunjwa, ukunciphisa ubukhulu kunye nokubonelela ngeempawu ezifunekayo kwisinyithi. Kule bhlog, siza kuphonononga ukubaluleka kokuqengqeleka kwamatye okungqusha kwaye sijonge ukuba anegalelo njani kuphuhliso lwenkqubo yokwenziwa kwemveliso.

Xa kuziwa kwii-rolling Mills, iimiquluthatha indawo ephambili. Ezi nxalenye ze-cylindrical zenzelwe ukujamelana noxinzelelo olunzulu, ubushushu kunye namandla avela ngexesha lokuqengqeleka. Umsebenzi wabo oyintloko kukusebenzisa amandla kwi-workpiece, nokuba yintsimbi, i-aluminium okanye nayiphi na enye isinyithi, ngaloo ndlela ibumba kwimo efunwayo. Imiqulu iququzelela inguqu ukusuka kwiingots okanye amacwecwe ukuya kwiimilo ezilawulekayo ezifana namaphepha, iipleyiti okanye ucingo.

Irola, elinye igama elidla ngokusetyenziswa ngokungafaniyo nelithi roll, liyinxalenye ebalulekileyo yelitye lokungqusha. Banoxanduva lokunciphisa ubukhulu bentsimbi njengoko idlula kwi-rolling mill. Ii-roller zisebenzisa uxinzelelo kwintsimbi, ngokuthe ngcembe zinciphisa ubukhulu bayo ngelixa zigcina ububanzi obuhambelanayo. Le nkqubo iqinisekisa ukuhambelana kwemveliso yokugqibela, ingaba i-sheet sheet esetyenziswe kwishishini leemoto okanye iikhoyili kwizicelo zombane.

Iintlobo ezahlukeneyo zosetyenziso kwiishishini lentsimbibavule indlela yophuhliso lwemiqulu eyahlukeneyo efanelekileyo kwiinkqubo ezahlukeneyo. Ngokuxhomekeke kwiimfuno ezithile ze-rolling mill, izinto eziphathekayo, ubungakanani, unyango lobushushu kunye nokugqitywa komphezulu wee-rolls kunokwahluka. Iintlobo eziqhelekileyo zibandakanyaimiqulu yomsebenzi, imiqulu yokugcinakunye nemiqulu ephakathi. Imiqulu yomsebenzi idibanisa ngokuthe ngqo kunye nentsimbi, ngelixa i-back-up rolls inikezela ngenkxaso kunye nokuthintela iziphene zemilo ezibangelwa iimeko zoxinzelelo oluphezulu. Iirola eliphakathiinceda ukwahlula ii-rollers zomsebenzi kunye nokulungelelanisa ukuxhatshazwa kwezinto.

Ukukhetha iiroli ezikumgangatho ophezulu kubalulekile ekugcineni ukusebenza kakuhle kunye nemveliso yelitye lakho lokusila. Iiroli ezineepropathi ezigqwesileyo zezinto ezibonakalayo, ezinje ngokunxiba okuphezulu, ubushushu kunye nokumelana nokudinwa, zinokumelana neemeko ezinzima zokuqengqeleka imini nemini, ukunciphisa ixesha lokuphumla kunye nokwandisa ubomi benkonzo. Ukongeza, imilinganiselo echanekileyo, ukugqitywa kwendawo echanekileyo kunye nokulungelelaniswa komqulu ofanelekileyo kunceda ukuphucula umgangatho wemveliso, ukunciphisa inkunkuma yezinto eziphathekayo kunye nokuphucula ukusebenza kakuhle ngokubanzi.

Ukutyhubela iminyaka, inkqubela phambili kwisayensi ye-metallurgical kunye nobunjineli iguqule uyilo kunye nokuveliswa kweeroli zokusila. I-alloys ehlaziyiweyo, njengentsimbi yesantya esiphezulu, insimbi yesixhobo kunye namabakala ahlukeneyo e-carbide, ukuphucula ukusebenza kunye nokuqina kwemiqulu. Ukongeza, ukuqhubela phambili kwitekhnoloji yokuvelisa i-roll efana ne-centrifugal casting kunye neenkqubo zokunyanga ukushisa zidlale indima ebalulekileyo ekuphuculeni ubomi kunye nokusebenza kwee-rolling rolls rolls.

Ngamafutshane, imiqulu yokusila isebenza njengamaqhawe angaziwayo, iququzelela ukuguqulwa kweentsimbi zibe yimveliso yexabiso elawula imizi-mveliso emininzi. Ukususela ekubunjweni nasekunciphiseni ubukhulu ukuya kwiipropati ezifunwayo kwintsimbi, imiqulu iyinxalenye ebalulekileyo yenkqubo yokuqengqeleka. Ngokuqonda ukubaluleka kweeroli kunye nokwamkela inkqubela phambili yetekhnoloji, abavelisi banokuwenza ngokupheleleyo umsebenzi wabo wokusila, bafezekise imveliso ephezulu, kwaye bazise iimveliso ezisemgangathweni ukuhlangabezana neemfuno ezikhulayo zeshishini lanamhlanje.
