Umbhobho wentsimbi ongenamthungo yenziwe ngomatshini kwibillet eyenziwe.Iplanti yentsimbi encinci, ngenxa yokunqongophala kwamandla okusebenza, ayithengwanga ibe yintsimbi yentsimbi ngokwabo, kodwa ithenge intsimbi eshinyeneyo, emva kokubanda itsalwe emva kumzi-mveliso amaxesha amaninzi, ifumane ubungakanani obuncinci obungenamthungo, emva koko ukuya iplanti yokulungisa intsimbi ecolekileyo ukuze iqhubeke nomsebenzi.Inxalenye yangaphakathi umbhobho umphezulu uburhabaxa abavelisi baye bathumela umgangatho wangaphakathi ophezulu wentsimbi umbhobho boring roller, ukufumana umgangatho oqaqambileyo wangaphakathi.Kodwa kwinkqubo yokuqengqeleka ikruqula ngamanye amaxesha ifunyenwe ngaphakathi kumbhobho wentsimbi kunye ne-warping encinci.Ulusu lwe-Alice lunokuveliswa ngexesha lokudinwa kwe-BUE, inokuba yintsimbi ethandabuzekayo ngokwayo.

I-BUE ibhekisa kumqulu odikayo, obonakala kwincam yamaqhekeza amancinci okuncamathela kwentsimbi kunye nokuqina kwawo okuphezulu.Xa umphezulu wentsimbi umbhobho roll ekruqulayo, ekubeni izinto workpiece watyhala ukuqhekeka, ngoko ke chip phambi isixhobo ukuvelisa kakhulu uxinzelelo kunye ukukhuhlana ukuvelisa kakhulu ukusika ubushushu.Kwiqondo eliphezulu lobushushu kunye noxinzelelo, loo nxalenye ye-chip inxibelelana nesixhobo esingaphambili ngenxa yokungqubana, isantya sokuhamba siyacotha, senza "inqanaba lokuhlala."Xa imathiriyeli yokukhuhlana, kanye ngaphezu kwamandla okubopha phakathi kwelatisi yangaphakathi, "i-retention layer" kwezinye zezinto iya kuqhotyoshelwa ngaphambili kufuphi nencam yesixhobo ukwenza i-BUE.I-BUE ukuba ishiywe kumphezulu womatshini, ukubunjwa kwee-burrs, ukwandisa uburhabaxa bomphezulu.Umphezulu wangaphakathi ongenamthungo we-warp kunye ne-substrate idityaniswe kwisiseko ukusuka kwi-warped out, kungekhona into yangaphandle ibambelele kwi-substrate emva kokukhutshwa.I-BUE kufuneka ibambelele kwindawo engenamthungo ayiyi kudibaniswa nomphezulu wangaphakathi wombhobho wentsimbi ukusuka kwi-matrix microstructure yokujonga.Ke ngoko, umphezulu wangaphakathi we-warp engenamthungo kufuneka wenziwe hayi ngokwenza i-BUE roll ekruqulayo, kodwa hayi ukubunjwa komcimbi wangaphandle.Imathiriyeli idlula kwizintlu ezimbini ezitsalwa ngokubanda, ezitsalwa ngokubanda zombini emva kokufakwa kwakhona kwekristali nganye, emva kwethemba lokubanda lokufumana iinkozo ezilinganayo zeferrite kunye neperilite equiaxed.Kodwa isampulu microscopic wemathiriyeli ngokucacileyo iinkozo ezirhabaxa, kwaye usasazo ayilingani kakhulu kwaye ukufumana ekuhlaleni Wilcoxon, ibonisa imathiriyeli ngexesha unyango ubushushu ngokugqithisileyo kakhulu.Iinkozo ezirhabaxa eziveliswe emva kobushushu obugqithisileyo, zatshabalalisa ubume boqobo obushinyeneyo obuziinkozo, emva kokuba umzobo obandayo wepearlite kunye ne-ferrite yaba yibhanti yeperilite kunye ne-ferrite lula stratification.Emva kokukruqula kwintsimbi yokuqengqeleka, isixhobo kwisixhobo sokusebenza ngamandla amakhulu ocinezelayo, emva koko umbhobho uthambekele ekujikeni.Ngokucacileyo ukutshisa kunyango lobushushu, sesona sizathu siphambili sokulwa nesizukulwana.

Ekubeni esona sizathu warping iveliswa ngexesha unyango ubushushu overheating intsimbi, kuyimfuneko ukulawula ubushushu annealing ngokulawula ubushushu annealing emva intsimbi ebandayo-drawn ukwenza ukufumana iyunifomu entle equiaxed ferrite kunye pearlite.Iinkozo ezilinganayo ezifanayo zidibanisa ukwenza iinkozo zibe nobuchule ngakumbi, ukuze ukomelela kunye nokuqina kwentsimbi kulungile.

Abavelisi bombhobho wentsimbi otsalwa ngokubanda ukuze kugcinwe iindleko, badla ukunciphisa inani lomzobo, kwaye ixesha ngalinye ubuncinci bedayamitha njengoko umbhobho utsalwa, ngoko kunokubangela ukutsalwa okugqithisileyo kombhobho wentsimbi kunokumelana nowona mgangatho uphezulu, kunye nokwanda koxinzelelo lwangaphakathi. umbhobho, umbhobho wensimbi phantsi kweempembelelo zangaphandle ngeziphene ze-extrusion ezifana nokuqhekeka ngokulula.Ke ngoko, ubushushu obulawulwayo bonyango lobushushu ngelixa ulawula umzobo ngamnye wentsimbi etsalwa ngokubanda uyimfuneko kakhulu.
