Ukwakheka Kwe-Cold Roll (Cold Roll Forming) inqubo yokubumba eqhubeka nokugoqa ama-coil ensimbi ngokusebenzisa ama-multi-pass forming rolls ahlelwe ngokulandelana ukuze kukhiqizwe amaphrofayili ezimo ezithile.
(1) Ingxenye yokwakha ama-rough isebenzisa inhlanganisela yama-roll ahlanganyelwe kanye nama-roll athathelwa indawo. Uma imininingwane yomkhiqizo ishintshwa, ama-roll ezinye izitendi akudingeki athathelwe indawo, okungasindisa amanye ama-roll reserve.
(2) Amashidi okugoqa ahlanganisiwe ama-roll ayisicaba, ingxenye yokwakha eqondile iyizitendi eziyisithupha, iqembu lokugoqa eliqondile lihlelwe ngokugobile, umthamo wama-roll ajikayo mncane, futhi isisindo sama-roll omshini wokwakha ama-roll wendabuko sincishisiwe ngaphezu kwe-1/3, futhi isakhiwo semishini sincane kakhulu.
(3) Ijika lokuma kwe-roll lilula, kulula ukulikhiqiza nokulungisa, futhi izinga lokusetshenziswa kabusha kwe-roll liphezulu.
(4) Ukwakheka kuzinzile, umshini wokugoqa usebenza kakhulu ekwakheni amashubhu anodonga oluncane kanye namashubhu anodonga lwangemuva, futhi ububanzi bemininingwane yomkhiqizo bubanzi.
Ukwakha i-Cold roll kuyinqubo entsha esindisa izinto, esindisa amandla futhi ephumelelayo kanye nobuchwepheshe obusha bokwakha insimbi eshidi. Ukusebenzisa le nqubo, akugcini nje ngokukhiqiza imikhiqizo yensimbi esezingeni eliphezulu, kodwa futhi kungafinyeza umjikelezo wokuthuthukiswa komkhiqizo, kuthuthukise ukusebenza kahle kokukhiqiza, ngaleyo ndlela kuthuthukise ukuncintisana kwemakethe kwamabhizinisi.
Eminyakeni engamashumi amahlanu edlule, ukwakheka kwe-cold roll kuye kwavela kwaba yindlela yokwenza insimbi eshidi esebenza kahle kakhulu. 35% ~ 45% yensimbi egoqwe eNyakatho Melika icutshungulwa ibe yimikhiqizo ngokugoba okubandayo, okungaphezu kwensimbi esetshenziswa embonini yezimoto.
Eminyakeni yamuva nje, imikhiqizo yensimbi eyakhiwe ngokubandayo isetshenziswe kabanzi njengezingxenye ezibalulekile zesakhiwo emikhakheni eminingi njengokwakha, ukukhiqizwa kwezimoto, ukwakha imikhumbi, imboni ye-elekthronikhi kanye nokukhiqizwa kwemishini. Imikhiqizo yayo isukela ezitimeleni ezijwayelekile zokuqondisa, iminyango namafasitela nezinye izingxenye zesakhiwo kuya kwezinye iphrofayili ezikhethekile ezenzelwe izinjongo ezikhethekile, ngezinhlobo eziningi. Ukusebenza kwesigaba ngesisindo seyunithi ngayinye sensimbi eyakhiwe ngokubandayo kungcono kunokwemikhiqizo yensimbi egoqwe ngokushisayo, futhi inokuqedwa okuphezulu kobuso kanye nokunemba kobukhulu. Ngakho-ke, ukufaka esikhundleni sensimbi egoqwe ngokushisayo ngensimbi eyakhiwe ngokubandayo kungafeza imiphumela emibili yokonga insimbi namandla, ngakho-ke abantu banesithakazelo ensimbini eyakhiwe ngokubandayo. Ukuthuthukiswa kwensimbi egobile kunikezwe ukunakwa okukhulu. Yisifiso esiqhubekayo sabasebenzisi sokuhlukahluka, ukucaciswa kanye nekhwalithi yemikhiqizo yensimbi eyakhiwe ngokubandayo okukhuthaza ukuthuthukiswa okusheshayo kobuchwepheshe bokwakha ngokubandayo.
