1. Nto Scale Cim
Lub ntsiab nta: tsis tsim txom ntawm tuagZam tximyuav ua rau cov chaw ntxhib thiab ntses teev teev. Xws li cov ntses nplai sib tw yog qhov yooj yim tsim tawm thaum forging Austenic thiab Martensitic Stainless hlau.
Cause: Mucous membrane tau tshwm sim los ntawm kev xaiv lubrication tsis muaj lubrication thiab tsis zoo ntawm cov roj lubricating.
2. Yuam kev tsis xws luag
Lub ntsiab tseem ceeb: lub sab sauv ntawm kev tuag forging yog misaligned txheeb ze rau qhov qis dua raws seem saum npoo.
Cause: Tsis muaj qhov tsis zoo uas kaw lub ntsuas phoo ntawm kev zam txim tuag, lossis kev tuag
3. Tsis muaj kev tuag
Lub ntsiab tseem ceeb: qhov loj ntawm kev tuag forging nce nyob rau hauv cov kev taw qhia mus rau parting nto. Thaum qhov loj tshaj qhov loj me hauv kev kos duab, tsis muaj kev tuag tsis txaus yuav tshwm sim.
Cause: Qhov loj me, qis forging kub, ntau dhau los ntawm cov tuag kab noj hniav, thiab lwm yam yuav ua rau tsis muaj kev cuam tshuam ntawm Flash Choj, thiab cov khoom siv tsis txaus siab, thiab ntau dua Billet ntim.
4. Cov hauv zos tsis txaus hauv zos
Lub ntsiab tseem ceeb: nws tshwm sim nyob rau hauv tus tav, conveyx tuag forgings, thiab sab saum toj ntawm kev zam txim, thiab cov ceg ntawm kev zam txim tsis tau muaj txaus, ua cov txheej txheem ntawm cov lus tsis paub meej
Vim li cas: tus qauv tsim ntawm cov tsis nyiam cov kab noj hniav thiab cov khoom siv tsis yog me me, thiab cov khoom siv hlau tsis zoo, thiab cov khoom tsis zoo, uas yuav ua rau qhov tsis xws luag.
5. Casting Cov Qauv Txheej Txheem
Lub ntsiab tseem ceeb: yog tias muaj cov ntawv sau tseg, lub elongation thiab qaug zog muaj zog ntawm kev tsis lees paub tsis pom zoo. Vim hais tias nyob rau hauv qhov qis-magnification daim ntawv, cov kwj ntawm cov khoom seem ntawm cov khoom siv, thiab txawm tias cov khoom siv dendidual tuaj yeem pom, uas feem ntau tshwm sim hauv kev lom zem siv cov hlau ingots li blanks.
Vim li cas: Vim tias tsis muaj kev lees paub thiab tsis txaus ntseeg kev zam txim. Qhov kev tsis haum no txo cov kev ua tau zoo ntawm kev tsis lees paub, tshwj xeeb tshaj yog cov kev cuam tshuam nyuaj thiab qaug zog muaj zog.
6. Nplej Inhomogeneity
Lub ntsiab nta: cov nplej hauv qee qhov ntawm covZam tximyog tshwj xeeb me ntsis, thaum cov nplej hauv lwm qhov yog me dua, ua cov nplej tsis sib xws. Kev kub-alloys thiab cov hlau kub-resistant tshwj xeeb tshaj yog cov nplej zom inomogeneity.
Cause: Qhov qis kawg nkaus forging qhov kub ua rau kev ua haujlwm hauv zos ua rau cov khoom siv kub ntawm cov hluav taws kub. Thaum lub sij hawm quenching thiab txheej txheem cua sov, qee cov nplej loj los yog thawj zaug tsis txaus ntseeg, ua rau muaj kev pom zoo, ua rau muaj kev cuam tshuam txog qhov tsis txaus ntseeg Qhov tsis sib xws ntawm cov nplej tau yooj yim ua rau ib qho kev txo qis hauv kev ua tau zoo thiab ua kom ntev.
7. Daim ntawv tais ceev tseg
Cov Nta tseem ceeb: cov kwj deg yog khoov ntawm cov quav ntawm cov qauv qis-magnification, thiab cov quav muaj zoo sib xws hauv cov kab nrib pleb. Yog tias nws yog qhov tawg, cov kwj deg yuav raug txiav ob zaug. Ntawm qhov loj-magnification trotimen, tsis zoo li hauv qab ntawm cov nrib pleb, ob sab yog oxidized heev thiab cov quav hauv qab yog blunt.
Cause: Nws yog feem ntau tshwm sim los ntawm kev txo qis heev, ntau dhau ntawm qhov thaiv me me los yog dhau ntawm cov txheej txheem sau cia ntawm cov txheej txheem kev zam thiab crankshaft tsis kam. Folding tej yam tsis xws luag ua rau cov oxidized nplaim hlau kom fuse ua ke thaum lub sijhawm forging.
8. Kev zam txim zam txim rau txoj kev xa tawm
Lub ntsiab tseem ceeb: ntws los ncig xws li streamline reflux, eddy, disconnection, thiab kev lees paub thaum forging yog tsawg zog.
Cause: Tus Qauv Tuag Tsis Txaus Ntseeg, Kev Xaiv Tsis Txaus Siab Rau Kev Zam Txim, tsis tsim nyog cov duab thiab Billet Loj.
9. Banded Qauv
Lub ntsiab tseem ceeb: tus qauv nyob rau hauv uas lwm cov qauv los yog ferrite theem hauv kev tsis nco qab yog faib rau hauv bands. Nws mas muaj nyob hauv Austenitic-Ferritic stainless hlau, ib nrab martensitic hlau thiab Eutectoid Steel.
Cause: Qhov no yog tshwm sim los ntawm kev tso cai deformation thaum ob pawg ntawm seem coexist. Nws txo qhov txuas ntxiv ntawm cov khoom siv sib txuas ntawm cov khoom thiab muaj feem cuam tshuam nrog thaj chaw ferrite lossis thaj tsam ntawm ob theem.
