Insundu eshisayo iyisigaba esiyisisekelo sensimbi yekhabhoni eyenziwa ngokugoqa impahla emazingeni okushisa aphezulu ngaphezu kwezinga lokubuyiselwa kabusha. Le nqubo yokukhiqiza idala imiqulu emikhulu namapuleti avame ukubizwa ngokuthi imiqulu eshisayo noma amapuleti ashisayo, okwenza insundu eshisayo ibe yisinqumo esisebenza kahle kwezinhlobonhlobo zezicelo ezakhiweni nezimboni. Inqubo yokugoqa eshisayo yenziwa emshinini wokugoqa oshisayo lapho izinsimbi zishiswe kabusha futhi zidluliselwe ezindaweni zokugoqa ukuze kufezekiswe ubukhulu obufunayo nezimfanelo zemishini. Ngoba impahla yakhiwa emazingeni okushisa aphakeme, insundu eshisayo ngokuvamile ibonisa indawo enesikali namalungiselelo avulelekile uma iqhathaniswa nezindlela ezisebenza ngobandayo. Abakhiqizi bahlukanisa imikhiqizo eshisayo ngaphansi kwezindinganiso ezifana ne-ASTM A1011 ezakhiweni zesakhiwo nemikhiqizo yemichilo, baqinisekisa ukuhambisana ekwakhiweni kwamakhemikhali nokusebenza kwemishini. Kubathengi nabacacisi, ukuqonda izisekelo zensundu eshisayo kusiza ukuhambisana nokukhethwa kwezinto nezindlela zokwakha, izinhloso zezindleko, nezidingo zokugcina zokusebenza.

Insundu eshisayo inezici eziningana ezichazayo nezomshini ezenza ilungele izicelo ezisindayo. Ukuvumelana kwayo nokuba namandla ezimweni zokukhiqiza ngokuvamile kuphezulu kunezinye izinsundu ezibandayo, ngenxa yokuvuseleleka okwenzeka ngesikhathi sokucubungula. Imikhiqizo ejwayelekile ye-coil eshisayo ibonisa ukuhlanganiswa okuhle futhi ingalolwa kalula ngezindlela ezijwayelekile zokwakha, futhi isakhiwo sezinhlamvu zayo sinikeza amandla alinganayo kanye nokwelula. Izici zendawo zihlanganisa isikali somshini kanye nokungalingani okungase kube khona; lezi zingasuswa ngokukhipha noma ngokucubungula okunye lapho kudingeka khona kwezicelo zobuhle noma zokunemba. Amazinga emboni afana ne-astm a1011 asiza ukucacisa amandla okukhiqiza, amandla okudonsa, kanye nokwakheka kwamakhemikhali okuvunyelwe ukuze abaklami nobunyengikazi bakwazi ukubikezela ukusebenza. Insundu eshisayo iphinde ibe nezingcindezi ezisele ezikhululwa ngesikhathi somshini we-hot strip kanye nokucubungula okulandelayo, okuthuthukisa ukuzinza kobukhulu ezicelo eziningi zokwakha nokukhiqiza.

Elinye lamazuzo amakhulu ensimbi eqotshwe ngokushisayo ukonga izindleko: ukukhiqiza insimbi eqotshwe ngokushisayo kusebenzisa amandla amancane kunokugotshwa okubandayo futhi kugwema izinyathelo zokuqedela eziningi, kunciphisa izindleko zezinto. Inqubo yokukhiqiza eyenziwa ngokudonswa kushisa noma ngokugotshwa kushisa ivumela ukuthi kwenziwe izigaba ezinkulu namapuleti amakhulu ngokulandelana, okwenza kube lula ukonga izindleko ezinkulu zensimbi ezakhiweni nemishini yezimboni. Ngoba insimbi eqotshwe ngokushisayo ikhiqizwa emazingeni okushisa aphezulu, kulula ukuyihlehlisa, okwenza lula imisebenzi yokubumba, ukugoba, nokushisela ezitolo. Uma iqhathaniswa nemikhiqizo eqotshwe ngokubandayo enezimfuno eziqinile, insimbi eqotshwe ngokushisayo ihlinzeka ngezimfanelo ezanele zemishini ezicelo lapho isiphetho sobubanzi nokulawula ubukhulu obuqinile kungabalulekile kakhulu. Amandla okuhlangabezana nezimfuneko ezifana ne-astm a1011 aqinisekisa ukuthi imikhiqizo eqotshwe ngokushisayo ihlangabezana nezimfuneko zamandla namakhemikhali ezicelo eziningi zokwakha nokukhiqiza, okufaka isandla ekwamukelweni kwawo kabanzi ekwakheni, ezokuthutha, nokukhiqizwa kwemishini esindayo.

Insundu eshisayo isetshenziswa kabanzi ezimbonini ngenxa yokuqina kwayo kanye nenani layo, izicelo ezijwayelekile zihlanganisa imishayo yesakhiwo, imigwaqo yesitimela, imishini yezolimo, kanye nemibhobho emikhulu. Amaphrojekthi okwakha nengqalasizinda avame ukuthembela ku-coil eshisayo ukuze kwenziwe ama-I-beams, iziteshi, namapuleti lapho kudingeka khona ukuhlanganiswa kwamandla kanye nenani elihle. Ekukhiqizeni, izinduku ezidonswe ngokushisa nezingxenye zizuza ekwenzeni kwempahla kanye nekhono lokwelashwa ngokushisa noma ukucutshungulwa kokuqhubekayo ukuze kutholwe izimfanelo zemishini ezihloselwe. Izingxenye zeshasha zezimoto, iziqongqo zezimboni, kanye nezindlu zemishini esindayo zihlanganisa i-strip eshisayo noma ipuleti ngoba ibekezelela ukushisela nokucubungula ngaphandle kokuqhekeka ngokweqile. Abahlinzeki nabakhiqizi bakhetha insundu eshisayo ezakhiweni zesikhashana noma zokuvikela lapho ukubukeka kungaphansi kokusebenza nenani.

Ukuqhathanisa insimbi eqotshwe ngokushisayo neyeqotshwe ngokubandayo kugqamisa ukushintshana phakathi kokuqedwa kwendawo, ukubekezelelana kobukhulu, kanye nezindleko. Insimbi eqotshwe ngokubandayo icubungulwa ezingeni lokushisa lokuhlala noma eduze kwalo ngakho-ke inikeza ukubekezelelana okungcono kakhulu kobukhulu, ukuqedwa kwendawo okubushelelayo, futhi ngokuvamile amandla amakhulu okukhiqiza ngenxa yokuqina komthwalo; nokho, lezi zinzuzo ziza ngezindleko eziphakeme zokukhiqiza nezokwakhiwa. I-coil eqotshwe ngokushisayo ne-plate eqotshwe ngokushisayo, ngokuphambene, ingabizi kakhulu ezinhlelweni zevolumu enkulu noma ezicini ezisindayo lapho ubukhulu obunembayo bungabalulekile. Lapho abaklami bedinga indawo enhle kakhulu yokupenda noma amagajini amancane anokwakheka okunembayo, bavame ukucacisa imikhiqizo eqotshwe ngokubandayo noma ukuqedela insimbi eqotshwe ngokushisayo ngokucwenga nokuphela ngokubandayo. Amazinga afana ne-astm a1011 ahlanganisa imininingwane ye-coil eqotshwe ngokushisayo, kanti ezinye izimemo ze-ASTM zingalawula izigaba ezigoqwe ngokubandayo, kusiza onjiniyela ukuthi bakhethe okufanele. Ukukhetha phakathi kokushisayo nokubandayo kugcina kuncike ezidingweni zomkhiqizo ophelile: ubuhle nokubekezelelana okuqinile kukhetha ukugoqwa okubandayo, kanti ubukhulu bokwakhiwa kanye nokonga izindleko kukhetha ukugoqwa okushisayo.

Ukwenziwa kwensimbi eshisiwe ngokuvamile kuhilela imboni ye-hot strip lapho izinsimbi ezishiswe kabusha zincishiswa ubukhulu ngama-rolling stands amaningi ukuze kwakheke i-hot rolled coil noma i-strip eqhubekayo. Imboni ye-hot strip idlala indima enkulu ekuchazeni izakhiwo zemishini kanye nokufana kobukhulu komkhiqizo wokugcina, ngokulawulwa kokupholisa kanye nama-finishing passes asetshenziselwa ukulungisa i-yield strength kanye ne-toughness. Ezingxenyeni ezithile, isinyathelo sokudweba okushisayo noma ukubumba okushisayo silandela ukugoqwa kokuqala ukuze kwakhiwe ama-bars, amapayipi, noma izigaba ezinokunemba okuthile kwe-cross-section kanye nezakhiwo zemishini. Lezi zinqubo zokudweba okushisayo zingathuthukisa isakhiwo sezinhlamvu futhi zithuthukise ukufana kuyo yonke ingxenye, zithuthukise ukusebenza kwemishini kwezicelo ezidinga kakhulu. Ukuhlanganiswa kwemisebenzi ye-hot strip mill nezinqubo zokudweba okushisayo ezilandelayo kuvumela abakhiqizi ukuthi banikeze izinhlobonhlobo eziningi zezimo zensimbi ezishiswe ngokushisayo—ama-coils, ama-plates, ama-bars, nezigaba—ezihlangabezana nezidingo ezahlukene zemakethe. Ukuqonda lezi zindlela zokukhiqiza kusiza abaphathi bokuthenga ukuthi bakhethe isimo esifanele kanye nezinga lokucubungula, noma ngabe i-oda lidinga i-hot rolled coil yokusetshenziswa okukhulu noma ama-hot drawn bars amalungu esakhiwo anembayo.

Izindinganiso zezimboni ezifana ne-ASTM A1011 zinikeza uhlaka lwezidingo zezinto, imingcele yokwakheka kwamakhemikhali, nemingcele yezakhiwo zemishini yemikhiqizo yensimbi eqotshwe kushisa.
