Ngokuvamile, amancane naphakathi nendawo (H400×200 nangaphansi) Ama-H-beam ngokuvamile asebenzisa amabhilidi ayizikwele namabhilidi angama-rectangular, nosayizi omkhulu (H400×200 nangaphezulu) Imishayo ka-H ivamise ukusebenzisa amabhilidi anomumo okhethekile, futhi amabhilidi asakazayo angasetshenziselwa womabili amabhilidi angunxande nanomumo okhethekile.Ngemuva kokukalwa, i-billet evela ekubunjweni okuqhubekayo ilayishwa isinyathelo ngesinyathelo (noma uhlobo lwe-pusher, kuneziko elincane le-pusher elisetshenziselwa ukukhiqiza insimbi yesigaba) isithando sokushisa futhi sishiswe ku-1200-1250.°C ukuze akhululwe esithandweni.Iningi lamaziko okushisa ahambayo asebenzisa izibasi zokushisa eziphindwe kabili ezihlelwe phezulu naphansi, ezinganikeza ukulawula okungcono kakhulu kwezinga lokushisa kwamabhilidi emininingwane ehlukene futhi wonge uphethiloli.
Ngemuva kokuthi i-billet iphuma esithandweni somlilo, iqala ukuncishiswa ngamanzi angu-10-25MPa aphezulu, bese ithunyelwa ku-billet mill ukuze igoqe.Umshini ongenalutho ngokuvamile uyigayo elinama-roll amabili ahlehliswayo (kukhona nama-roll amathathuumshini wokugayangensimbi encane, kodwa umkhawulo wenqubo awuhambisani nenhlangano yokukhiqiza), futhi umshini wokuvala udinga ukugoqwa cishe ama-5 kuya ku-13 ukudlula, bese ucezu olugoqiwe I-saha eshisayo inesibopho sokusika ingxenye engakalungiswa. ikhanda, kodwaisigundi esindizayoingasika ikhanda, ingxenye nomsila.Izingcezu ezigoqiwe ngemva kokusika ikhanda zithunyelwa emshinini wokuqeda ukugoqa.Ukuqedwa kokuphothula kwensimbi yesigaba esincane sabakhiqizi abakhulu basekhaya kusebenzisa indlela yokugoqa okuqhubekayo, futhi ukuphothula kwensimbi yesigaba esikhulu kuguquguqukayo.Ngemva kokuqeda ukugoqa, ngokuvamile ithunyelwa ngokuqondile embhedeni wokupholisa ukuze ipholiswe, kodwa kukhona nezigaba ezihlukaniswa ngaphambi kombhede wokupholisa noma ezisikwe ngemva kombhede wokupholisa.Ngenxa yomehluko omkhulu phakathi kobukhulu bemilenze kanye nobukhulu bokhalo lwensimbi yesigaba esikhulu, uma ibekwe isicaba, isivinini sokupholisa okhalo nemilenze asihambisani, okubangela amagagasi okhalweni, ame mpo. Ukupholisa ngokuvamile kusetshenziswa.Kodwa-ke, abakhiqizi abajwayelekile be-H-beams abancane bonke bayamukelaukunyathela imibhede yokupholisa izinyo, ezibekwe oblique ku-rack.Ukusebenzisa imibhede yokupholisa amazinyo anyathelayo akukwazi ukunciphisa kuphela amaphutha abangelwa umshini wokuqala wokudonsa amaketango, kodwa futhi kulawula kalula ukupholisa kwesivinini sensimbi.I-H-beam epholile ithunyelwa ku-umshini wokuqondisayokuqondisa.Ngenxa yengxenye enkulu ye-modulus ye-H-beams, imishini yokuqondisa engu-8-roll, 9-roll noma engu-10-roll ngokuvamile isetshenziselwa ukuqondisa, futhi ibanga elikhulu phakathi kwama-roller okuqondisayo lingafinyelela ku-2200mm.Ngemva kokuqondisa, insimbi ithunyelwa endaweni yokumasha ukuze ihlanganiswe futhi ilinde ukusaha.Ngemva kokusikwa ngesaha elibandayo ngokobude obunqunyiwe, ithunyelwa etafuleni lokuhlola ukuze kuhlolwe usayizi, ukwakheka kanye nekhwalithi yangaphandle, bese ihlelwa, ipakishwe futhi ihlanganiswe.ithunyelwe endaweni yokugcina izimpahla.Ngemikhiqizo engafanelekile, ngokusho kohlobo lwesici, ukuqondisa kabusha okuhambisanayo, ukugaya, ukulungiswa kwe-welding kanye nokunye ukwelashwa kuzokwenziwa, bese befaka uhlelo lokuhlola ikhwalithi ehambisanayo bese behlukaniswa endaweni yokugcina ngemva kokudlula ukuhlolwa.
Ukuze kuthuthukiswe izinga lokusebenza komshini wokugaya futhi kuncishiswe isikhathi sokushintsha umqulu, cishe bonke abakhiqizi bamukela uhlelo lokushintsha umqulu osheshayo, okungukuthi, imiqulu edingekayo ezinhlobonhlobo ezilandelayo ihlanganiswa kusengaphambili ngenkathi ikhiqiza.Lapho ushintsha ama-roll, vele ukhiphe wonke ama-racks asekuqaleni bese uwafaka esikhundleni sama-rack amasha afakiwe.Uhlaka ngalunye lufakwe iphaneli yokuxhuma esheshayo, ehlanganisa amanzi okupholisa, umfutho we-hydraulic, uwoyela omncane namajoyinti omile wamapayipi kawoyela kanye nemishini yokubeka indawo yokuxhuma izinduku.Idivayisi ilula futhi iyashesha ukuqaqa nokuxhuma, futhi sonke isikhathi sokushintsha umqulu cishe imizuzu eyi-10-20.Ngokuvumelana nesipiliyoni sokushintsha umqulu wensimbi encane, isikhathi sokushintsha umqulu sisonke cishe imizuzu engama-45-70.
