Njengoba umkhakha wezokukhiqiza ukhula, izigayo ezishisayo zidingeka emafekthri ahlukene ukuze zigingqe izinsimbi ezishisayo ngezinhloso ezahlukene.
Ukuginqika kwensimbi eshisayo kuyinqubo lapho insimbi ifudunyezwa ngaphezu kwezinga lokushisa lekristalu ukuze lonakale ngokwepulasitiki. I-deformation ivumela insimbi ukuthi ibunjwe ngendlela efiselekayo kanye nobukhulu.
Kukhona izigayo ezahlukene ezishisayo ezisetshenziswa ezimbonini ezahlukene. Lo mhlahlandlela uzosiza amabhizinisi ukuthi akhethe izigayo ezishisayo ezifanele izidingo zamakhasimende awo.

Isiphetho
Ukubuka konke kwemakethe yokugaya okushisayo
Imakethe yokugaya emhlabeni wonke kulindeleke ukuthi ikhule ngezinga lokukhula elihlanganisiwe lonyaka (CAGR) lika-3.7% eminyakeni eyisikhombisa ezayo.
Ukukhula kwemakethe yesigayo kuqhutshwa ukwanda kwesidingo semikhiqizo yensimbi emikhakheni yamandla, eyezimoto kanye neyokwakha.
Imakethe yokugaya ihlukaniswe ngenqubo, uhlobo lomshini, ukusetshenziswa kokuphela, kanye nokusetshenziswa. Ekugcineni, imakethe ihlukaniswa ngokwejwayelekile kwezokukhiqiza, ezokuvikela, ezamandla, ezokwakha, ezezimoto nezokuthutha.
INyakatho Melika iyona enkulu kunazo zonke hot rolling mill market ngenxa yokugxila okuphezulu kwezitshalo zokukhiqiza insimbi. I-India ne-China nazo zibhekene nesidingo esikhulayo sezigayo zensimbi.
Izinhlobo zezigayo ezishisayo
Izigayo eziginqikayo ezimbili eziphezulu
Lolu uhlobo olulula kunazo zonke lwe- umshini wokugaya oshisayo. Iqukethe amarola amabili azungezayo abheke ezinhlangothini eziphambene.
Izinto ezizogoqwa ziphakelwa phakathi kwe abaxiki, efaka ingcindezi ukuze ikhubaze futhi ilolonge impahla. Isiqondiso sokuzungezisa ama-roll asikwazi ukuguqulwa noma ukuguqulwa; ngakho-ke umsebenzi kufanele ufakwe emiqulwini ukusuka ohlangothini kuphela.
Izigayo eziginqikayo eziphakeme ezintathu
Okuthathuhigh rolling mill inamarola amathathu, nerola eyodwa ebekwe ngaphezu kwamanye amabili.
Izinto ezisetshenziswayo ziphakelwa phakathi kwe-roller ephezulu kanye nama-roller amabili aphansi, afaka ingcindezi yokuma nokuguqula izinto.
Inzuzo eyinhloko ye-roller ephezulu emithathu izimboni ukuthi impahla yokusebenza ingaphakelwa ohlangothini olulodwa phakathi kwemiqulu yokuqala neyesibili.
Izigayo ezine-high rolling
Izigayo ezine-high ziwuhlobo lwesigayo esigoqayo esisebenzisa amaroli amane ukuze kuncishiswe ubukhulu bomucu wensimbi noma ishidi.
Amaroli emshinini wokugoqa ophakeme kane ahlelwa ngephethini ephindwe kabili-ngaphezulu kwamabili, futhi ipheya ngalinye lisebenza ngendlela ehlukile.
Amaroli aphezulu naphansi kumshini wokugaya ophakeme kane makhulu kunamaroli amabili aphakathi nendawo amiswe phakathi kwawo. Ubukhulu obukhulu bemiqulu ephezulu nangaphansi buvumela ukucindezela okukhulu ukuthi kusetshenziswe kucezu lokusebenza, okuholela ekunciphiseni okuphawulekayo kokuqina.
Izigayo ze-Cluster rolling
Izigayo eziginqayo ze-Cluster zinamapheya amaningana emiqulu ahlelwe njengeqoqo, ipheya ngayinye yamaroli asebenza ngokuhambisana.
Igingqa ngeqoqo umshini wokugaya ahlelwa ngephethini ethile, ngokuvamile abe umumo wedayimane noma iqoqo lamaroli amane noma ngaphezulu. I-workpiece idlula phakathi nendawo yeqoqo futhi ingaphansi kokuncishiswa okuningi kogqinsi njengoba idlula kusethi ngayinye yamaroli.
Lo mklamo uvumela ukuguquguquka okukhulu kanye nohlu olubanzi lwamasayizi womkhiqizo. Izigayo ze-Cluster rolling zikhiqiza imikhiqizo yekhwalithi ephezulu, enembayo ephezulu njengezingxenye zezimoto, ama-bearing, nezinto ze-aerospace.
Izigayo ezigoqayo ze-Tandem
Izigayo eziningana eziginqayo zihlelwa ngochungechunge emshinini ogoqayo we-tandem, ngasinye senza umsebenzi othile.
Izinto ezisetshenziswayo zidlula endaweni ngayinye ngokushintshana, isitendi ngasinye sibe negalelo ekumeni kokugcina nosayizi womkhiqizo.
Izigayo eziginqayo ze-Tandem zingafinyelela ukuncipha okuphezulu kogqinsi kunezigayo zesitendi esisodwa futhi zingasetshenziswa ukukhiqiza uhla olubanzi lwemikhiqizo.
Isigayo se-Steckel
Isigayo se-Steckel isigayo esiginqikayo esisetshenziselwa ukukhiqiza amakhoyili ensimbi aginqike ngekhwalithi ephezulu. Iqanjwe ngomsunguli wayo, u-Edward Steckel, onelungelo lobunikazi bomklamo ngo-1923.
Isigayo se-Steckel sihlanganisa isigayo esiphendukayo esiphendukayo kanye ne-caster eqhubekayo. Emshinini wokugaya wendabuko, i-slab yensimbi igoqwa ngokuphindaphindiwe ukuze kuncishiswe ukujiya kwayo nokuyilungisa ibe ikhoyili noma ishidi. Kodwa-ke, kumshini wokugaya we-Steckel, insimbi iphonswa ngokuqondile emgqeni oshisayo, bese igoqwa ochungechungeni lwezitendi eziginqikayo ukuze kuzuzwe ukujiya nokuma okufunayo.
Enye yezinzuzo eziyinhloko zesigayo se-Steckel yikhono layo lokukhiqiza imikhiqizo yensimbi esezingeni eliphezulu, engabizi kakhulu enobubanzi obubanzi nobubanzi.
Indlela yokukhetha i-hot rolling mill
Ukukhetha a umshini wokugaya oshisayo kudinga ukucatshangelwa ngokucophelela kwezici ezimbalwa, okuhlanganisa uhlobo nosayizi wento ezosongwa, imininingwane yomkhiqizo oyifunayo, kanye nevolumu yokukhiqiza.
Nazi ezinye izici ezibalulekile okufanele uzicabangele lapho ukhetha umshini wokugaya oshisayo:
Uhlobo lwezinto kanye nosayizi
Cabangela izici zento ezosongwa, njengokwakheka kwayo, ukujiya, nobubanzi. Ezinye izigayo zingase zifaneleke kangcono izinto ezithile noma osayizi bomkhiqizo kunabanye.
Ukucaciswa Mkhiqizo
Nquma ukucaciswa okufunayo komkhiqizo wokugcina, njengokujiya, ububanzi, isiphetho sendawo, kanye nezakhiwo zemishini. Khetha umshini wokugaya ongahlangabezana nalokhu kucaciswa ngokunemba okuphezulu nokuvumelana.
Ivolumu yokukhiqiza
Cabangela umthamo wokukhiqiza odingekayo, njengoba ezinye izigayo zifaneleka kangcono ukukhiqizwa kwevolumu ephezulu kunezinye. Ukwengeza, cabangela ukusebenza kahle nokusebenza kwesigayo, kanye nezidingo zayo zokuyinakekela kanye nesikhathi sokuphumula.
Izidingo zokukhiqiza zekhasimende ngalinye ziyahlukahluka, futhi umthamo wokukhiqiza wezigayo ezishisayo ezikhethiwe kufanele ufane nalezi zidingo.
Izindleko kanye nesabelomali
Nquma isabelomali somshini wokugaya, futhi uqhathanise izindleko zezinketho ezahlukene ukuze uthole inani elingcono kakhulu lokutshalwa kwezimali. Intengo emaphakathi yesigayo esishisayo iqala ku-$60,000.
Kuwutshalomali olukhulu, kodwa imbuyiselo cishe izolibiza inani. Ngakho-ke kubalulekile ukukhetha i-hot rolling mill ehlangabezana nesabelomali esilindelekile sekhasimende lakho.
Ubuchwepheshe nokusekelwa
Okokugcina, kubalulekile ukucabangela ubuchwepheshe kanye nezinga losekelo lomkhiqizi noma umphakeli. Bheka umphakeli onomlando oqinile wekhwalithi nokwethembeka futhi onganikeza ukuqeqeshwa, ukusekelwa kobuchwepheshe, nezinsimbi eziyisipele njengoba kudingeka.
Ukwesekwa kwangemva kokuthengisa kubalulekile ekuqinisekiseni ukuthi ikhasimende lakho liyakwazi ukufinyelela kubuchwepheshe obudingekayo ukuze uqinisekise ukuqhubeka kwebhizinisi.
Isiphetho
Izigayo ezishisayo zibalulekile ezimbonini eziningi ngenxa yokwanda kokusetshenziswa kwensimbi ekukhiqizeni, ekwakheni, embonini kawoyela, nasekuvikeleni. Isibikezelo semboni sibukeka siqhakazile futhi isidingo sizoqhubeka nokwanda njengoba izifunda emhlabeni wonke ziqhubeka nokwandisa ukukhiqizwa kwazo kanye nezimboni.
Amabhizinisi asemkhakheni wemishini kufanele acabangele izigayo zokugawula amasheya kanye nokumaketha ukuze azuze ekukhuleni kwesidingo. Vakashela Chovm.com ukufakwa kuhlu kwemishini yokugaya esezingeni eliphezulu.
