Kev Yuav Tsum Kom Rauv Rauv Hauv Cov Khoom Uas Muaj Duab Ntau Lawm
Oct 11, 2017


Graphite Tuag nyob rau hauv lub forging cog ntau lawm, qhov muaj qhov loj ntawm cov pob hlau ua ntej lub cub tawg yuav tsum yog nws lub cub hluav taws xob, nws muaj roj, hnyav, loj, thiab kos cov dej zoo, tshem tawm cov teeb meem ntawm qhov chaw. Sau rau qhov chaw ntawm lub tshuab ua kom sov, ua cov lag luam ntawm Graphite Die cov ntaub ntawv pov tseg.
Txoj hauj lwm ntawm cov pob zeb uas siv los siv hauv cov Txwv Txwv uas siv los ua cov Txwv Sib Thoob yuav tsum txiav txim siab raws li qhov cub tawg, qhov loj hauv qab, qhov cub tawg, thiab qhov loj thiab qhov hnyav ntawm cov rhuab pob zeb kom txiav txim siab qhov kev ncua deb ntawm lub tshuab ua kom sov, hauv ntej thiab nram qab phab ntsa thiab burner. Nws yog forbidden mus ncaj qha rau ntawm cov hlau ntawm cov Graphite tuag. Graphite Dies yuav tsum tau siv thaum muaj cua sov rau forging. Qhov siab ntawm lub horn yuav tsum tsis txhob qis dua qhov siab ntawm qhov cub rau hauv qab taws kub. Ncauj los yog sab ntev ntev dua 150mm Graphite Die billet cua sov tsis tau siv horn.
Graphite Die siv nyob rau hauv lub cub tawg rau hauv qhov cub ua ntej kub kub qis tshaj 400 ℃ hu ua txias hlau ingots, 400-550 ℃ hu ua semi-hot steel ingots, siab tshaj 500 ℃ hu ua kub hlau ingots. Kub thiab txias steel ingot (billet) nrog cua sov, qhov sib kis ntawm cov khoom yuav tsum yog ntau dua li lub voj voog loj los yog sab ntev. Yuav tsum sim kom tsis txhob kub thiab txias qij txhaws nrog lub cub tawg.
Nws yog cai txwv tsis pub muab cov hlau txias txig (billet) ntawm ib sab rhuab graphite. Nws yog txwv tsis pub ua kom cov cua sov (tshav) ncaj qha nrog lub ntsuas ntawm qhov ntxaiv hauv qab 0 ℃. Kev soj ntsuam cov khoom siv hlau kub uas tsim nyog mus rau Graphite Die Rhiav kev tuav pov hwm, yuav tsum tsis txhob cia cua txias ncaj tshuab, yuav tsum muaj cua kub tuaj yeem, yuav tsum tsis txhob ncua lub tshuab ua kom sov.
Lub caij pib forging kub ntawm qhov Graphite Die yog qhov siab tshaj plaws cua sov kub ntawm raw cov ntaub ntawv nyob rau hauv qhov cub cua sov. Graphite Die factory los ntawm lub cub tawg kom tshem tawm cov khoom tsis muaj peev xwm ua kom tsis pub ua ntej, ua raws li qhov sib txawv, qhov ntawm kev thauj khoom thiab qhov sib txawv ntawm qhov cub tawg thiab cov khoom siv hluav taws xob, qhov roughness ntawm ob peb degrees rau ob peb degrees kub poob. Yog li ntawd, qhov tiag pib forging qhov kub yog me ntsis qis dua, ua ntej lub forging, Graphite tuag lub Hoobkas yuav tsum sim los txo cov kub kub poob.
Qhov pib lub forging kub ntawm hlau alloy hlau thiab hlau alloy steels yog tsuas yog los ntawm tshav kub thiab overcooling kub. Cov cua sov tshaj dhau ntawm cov hlau yog li 100 txog 150 ° C qis dua ntawm qhov nruab nrab, thiab kub kub kub li 50 ° C qis tshaj qhov kub tshaj. Yog li, pib lub forging qhov kub ntawm cov hlau yuav tsum qis tshaj qhov nruab nrab ntawm qhov chaw (los yog hauv qab kub kub) 200 ° C.
Cov ntsiab lus ntawm cov ntsiab lus muaj cov nyhuv tseem ceeb tshaj plaws nyob rau sab nruab nrab ntawm cov hlau forging. Rau cov steel steel Graphite Tuag, pib lub forging kub txo nrog cov nce ntawm cov ntsiab lus. Rau alloy structural hlau thiab hlau alloy tuag hlau, feem ntau pib lub forging kub decreases nrog nce nyob rau hauv cov ntsiab lus ntau.
Thawj cov qauv ntawm cov pob zeb yog qhov ruaj khov thiab qhov sib npaug heev yog qhov me me. Yog li ntawd, lub forging kub ntawm lub ingot yog 20 ~ 30 ℃ siab tshaj hais tias ntawm steel hlau thiab steel.
Qhov sib npaug heev, hais txog cov cua kub ntau tshaj li qhov ntsuas kub, nws yuav tsim cov noob txiv ntsej muag loj hlob sai. Qhov kev sib txawv ntawm cov hlau sib txawv los yog sib tshuam yog txawv, qhov muag hlau yog tsis tshua muaj siab heev, thiab hlau hlau yog ib qho yooj yim rau kev sib tw, nyob rau hauv cov tshav kub-rhiab hlau, cov xim nickel-chromium molybdenum yog qhov tseem ceeb tshaj plaws.
Graphite Die overheating thiab tshuaj muaj pes tsawg leeg, kev ua kom zoo, kev sib zog ua kom sov, thermal deformation, forging txias npaum li cas thiab cua txias uniformity thiab lwm yam. Vim tias kub ntxhov los yog lub caij sov so ntau dhau los, tab sis lub caij nplooj ntoos zeeg yuav raug rhuav tshem ntau heev, tab sis feem ntau los ntawm cov deformation deformation thiab deformation uniformity ntawm cov kev txwv, Graphite tuag rau ntau overheating, forging deformation tsis yog yooj yim mus kiag tawm. Yog li ntawd, yuav tsum tau ua kom muaj kev nyab xeeb ntawm lub forging kub kub kom tiv thaiv kom tsis txhob overheating. Raws li kev kub hnyiab, vim hais tias cov cua sov kub kub yog siab tshaj, cov hlau phom loj heev, thiab oxygen atoms raws ciam ciam cuam tshuam, tsim kev zoo li lub network xws li oxide thiab fusible oxide eutectic, thiaj li khoov quab yuam ntawm cov grains tsis muaj zog txaus Ua raws li los ntawm thermal deformation yog yooj yim los tsim cracking.
