Ipayipi lensimbi elingenamthungo yenziwe ngomshini kusuka ku-billet eyenziwe.Imboni encane yensimbi, ngenxa yokuntuleka komthamo wokucubungula, akuthengi okuthengiwe kucutshungulwa kube amabhilidi ensimbi ngokwawo, kodwa thenga insimbi enodonga oluwugqinsi, ngemva kokubanda ibuyiselwe efekthri izikhathi eziningana, thola usayizi omncane ongenamthungo, bese uya isitshalo esihle sokucubungula insimbi ukuze siqhubeke nokusebenza.Ingxenye yangaphakathi yepayipi elingaphakathi abakhiqizi bobuqhwaga bathumele indawo yangaphakathi ephakeme ye-roller eyisicefe yepayipi, ukuze bathole indawo yangaphakathi ekhanyayo.Kodwa inqubo rolling boring ngezinye izikhathi kutholakala ngaphakathi ipayipi steel nge warping encane.Isikhumba sika-Alice singase sikhiqizwe ngesikhathi se-BUE roll eyisicefe, ingaba ngensimbi yekhwalithi engabazekayo ngokwayo.

I-BUE isho umqulu oyisicefe, ovela esihlokweni sezingcezu ezincane zokunamathela kwensimbi kanye nokuqina kwayo okuphezulu.Lapho ebusweni ipayipi steel roll boring, kusukela workpiece impahla iphushwa crack, ngakho chip phambi ithuluzi ukukhiqiza eziningi ingcindezi kanye friction ukukhiqiza eziningi ukusika ukushisa.Emazingeni okushisa aphezulu kangaka nokucindezela, leyo ngxenye ye-chip ithintana nethuluzi elingaphambili ngenxa yokungqubuzana, izinga lokugeleza liyehliswa ngokuqhathaniswa, lenze "izinga lokuhlala."Uma okokusebenza kokungqubuzana, kanye kungaphezu kwamandla abophayo phakathi kwelathisi yangaphakathi, “ungqimba lokugcina” kokunye okokusebenza luzonamathiselwa ngaphambili eduze kwesihloko sethuluzi ukuze kwenziwe i-BUE.I-BUE uma ishiywe endaweni eyenziwe ngomshini, ukwakheka kwama-burrs, okwandisa ubulukhuni obungaphezulu.Indawo engaphakathi engenamthungo ye-warp kanye ne-substrate ixhunywe esisekelweni kusukela kokusontekile, hhayi indaba yangaphandle enamathela ku-substrate ngemva kokukhishwa.I-BUE kufanele inamathelwe endaweni engenamthungo akufanele ixhunywe nendawo engaphakathi yepayipi lensimbi kusukela kusakhiwo se-matrix sokubuka.Ngakho-ke, indawo engaphakathi ye-warp engenamthungo akufanele idalwe ngokubunjwa kwe-BUE roll, kodwa hhayi ukwakheka kwezinto zangaphandle.Okubalulekile kudlula ezintweni ezimbili ezidonswa ngokubanda, ezidonswa ngokubanda zombili ngemva kokufakwa kabusha kwe-recrystallization ngakunye, ngemva kokuthungatha amathemba okuthola okusanhlamvu okulinganayo kwe-ferrite ne-pearlite equiaxed.Kodwa isampula encane yezinto ezibonakalayo ngokusobala yizinhlamvu ezimahhadla, futhi ukusatshalaliswa akufani kakhulu futhi kuthola i-Wilcoxon yasendaweni, ikhombisa okokusebenza ngesikhathi sokwelashwa kokushisa kushisa kakhulu.Izinhlamvu ezimahhadla ezikhiqizwe ngemva kokushisisa ngokweqile, zacekela phansi ukwakheka kokusanhlamvu okuminyene kwasekuqaleni, ngemva kokuba umdwebo obandayo we-pearlite kanye ne-ferrite zaba i-pearlite enebhande kanye ne-ferrite stratification lula.Ngemuva kokubhoboza ekugoqeni kwensimbi, ithuluzi eliya endaweni yokusebenza ngamandla amakhulu okucindezela, bese lipayipi lithambekele ekujikeni.Ngokusobala ukushisa ngokweqile ekwelapheni ukushisa, kuyisizathu esiyinhloko esenza isizukulwane.

Njengoba isizathu esiyinhloko se-warping sikhiqizwa ngesikhathi sokwelashwa kokushisa kokushisa okweqile kwensimbi, kuyadingeka ukulawula izinga lokushisa le-annealing ngokulawula izinga lokushisa le-annealing ngemva kwensimbi edonswa ngokubanda ukuze wenze ukuthola i-ferrite elinganayo elinganayo ne-pearlite efanayo.Izinhlamvu ezilinganayo ezifanayo zihlangana ukwenza okusanhlamvu kube yinkimbinkimbi, ukuze amandla nokuqina kwensimbi kube kuhle.

Abakhiqizi bepayipi lensimbi elidonswa ngokubanda ukuze bonge izindleko, bavame ukunciphisa inani lomdwebo, futhi isikhathi ngasinye ububanzi obuncane njengoba ipayipi lidonsa, ngakho-ke kungase kubangele ukudonsa ngokweqile phezu kwepayipi lensimbi kungamelana nobukhulu, nokwanda kokucindezeleka kwangaphakathi. ipayipi, ipayipi lensimbi ngaphansi kwethonya langaphandle ngokukhubazeka kwe-extrusion njengokuqhekeka kalula.Ngakho-ke, izinga lokushisa elilawulwayo lokwelashwa kokushisa ngenkathi kulawulwa umdwebo ngamunye wensimbi edonsa ngokubanda kuyadingeka kakhulu.
