I-Coefficient yokwandiswa kweumbhobho wentsimbi echanekileyo

Khangela indlela enokusetyenziswa kwisithando somlilo, amanzi anesepha ukosula umngxuma ngamnye odibeneyo, ukubona ukuba kuqhutywe irhasi;iindawo apho irhasi inokuthi ingene kwityhubhu yesithando somlilo kwaye ibeke ityhubhu endaweni, le ndawo itywina isengozini yokukrazuka, Jonga rhoqo rhoqo.Ithiwe thaca phambi kokwenziwa komqulu weskimu senkqubo yokulungiswa kwentsimbi echanekileyo;uhlalutyo lweqondo lokushisa eliqhelekileyo, ixesha lokubamba kunye nempembelelo yokupholisa ye-microstructure ye-tube ye-raw material kunye ne-mechanical properties;ukugqiba inkqubo yesiqhelo yokulungisa iityhubhu zentsimbi ezichanekileyo: ubushushu bokufudumala (890 ± 10) ℃, ukupholisa umoya emva kokubamba i-6min edibeneyo.Inkqubo yesiqhelo yokulinganisa inokupheliswa ngokupheleleyo intsimbi echanekileyo iWidmanstaten ukuze itshatise amandla esivuno kunye namandla okuqina aqiqisekile umlinganiselo wesivuno σS / bσ≤0.78, ulwandiso 5δ≥30%, kwaye kuphuculwe kakhulu ukumila okubandayo kunqanda ukuqhekeka okubandayo.I-coefficient yokwandisa ingabonakaliswa ngomthamo okanye ubude buvame ukubonakaliswa ngokobude.

Uxinaniso luxinaniso lobunzima bezinto kwiyunithi nganye umthamo wento, iyunithi yi-kg / m3 okanye 1b/in3.Uxinzelelo lwentsalela ye-tensile ubukhulu becala lusuka kuxinzelelo olushiyekileyo oluveliswe kwisixhobo ngexesha lenkqubo ye-welding.Okwangoku, isetyenziswa ngokubanzi kunyango lwe-annealing yobunjineli ukuphelisa uxinzelelo olushiyekileyo emva kokupholisa kwe-welding, kunye nokupholisa emva koxinzelelo lwe-welding residual yinkqubo ebalulekileyo, le ndlela yinkcitho yamandla kwaye kulula ukuba ne-welding enkulu yoxinzelelo lwentsalela.Unyango lwe-post weld heat yitekhnoloji entsha yokuphelisa uxinzelelo olushiyekileyo.Phambi ukuwelda ukuchaneka umbhobho yentsimbi preheated ukuya iqondo lobushushu unyango kunye welding inkqubo weldment kuqhubeka ukufudumeza ukugcina lo bushushu, ukusetyenziswa welding kugqitywe umqhaphu ukwahlukanisa ukwahlukanisa avunyelwe ukuba kuphole kancinane.Ukucima umbhobho wentsimbi ukwandisa amandla kunye nobunzima, kodwa ukunciphisa iplastiki yabo.Cima i-agent yokuqina esetyenziswa ngokuqhelekileyo emanzini, ioli, ityuwa kunye nesisombululo sealkali kunye nokunye okunjalo.Iza kuba nentsimbi echanekileyo epholileyo, yenze lukhuni intsimbi echanekileyo iphinde ifudunyezwe kubushushu obuthile, kunye nendlela ethile yokupholisa eyaziwa ngokuba yi tempering.Injongo yalo kukuphelisa uxinzelelo lwangaphakathi oluveliswa ngokucinywa ukunciphisa ubunzima kunye ne-brittleness, ukuze kufumaneke iipropati ezifunwayo zoomatshini.Amanqaku okuthoba ubushushu obuphezulu, ubushushu kunye nobushushu obuphantsi bobushushu amacandelo amathathu.Ukucima okuninzi kunye nokufudumeza, ukuqhelekileyo kusetyenziswe ngokudibeneyo.Emva kokucima kunye nokutshisa indlela yokucima ibizwa ngokuba yi-quenching.
