Kev tawg ua rau lub nplhaib tuag yog qhov nyuaj thiab yuav tsum tau txheeb xyuas kom meej.Tab sis nws tuaj yeem raug suav hais tias yog vim li cas hauv qab no.
1. Cov khoom siv hauv lub nplhaib pwm yog ib qho ntawm cov laj thawj tseem ceeb.Tam sim no, 4Cr13 thiab 20CrMnTid feem ntau yog siv nyob rau hauv peb lub teb chaws, uas yog qhov ruaj khov.Tab sis cov khoom lag luam sib txawv, rau cov khoom siv tib yam, cov kab ke yuav muaj qhov sib txawv, yuav cuam tshuam rau qhov zoo ntawm lub nplhaib pwm.
2. txheej txheem forging.Qhov no yog qhov txuas tseem ceeb hauv kev tsim pwm.Rau siab alloy steel pwm, qhov yuav tsum tau ntawm cov khoom carbide faib thiab lwm yam metallographic qauv feem ntau yog muab tso rau pem hauv ntej.Nws tseem yog ib qho tsim nyog yuav tsum nruj me ntsis tswj qhov ntsuas kub ntawm forging, tsim cov cua kub kom raug, txais yuav txoj kev forging kom raug, thiab ua kom txias txias los yog lub sij hawm annealing tom qab forging.Cov txheej txheem tsis yog txheej txheem yog ib qho yooj yim uas yuav ua rau tawg ntawm lub nplhaib tuag lub cev.
3. Npaj rau kev kho cua sov.Raws li cov khoom sib txawv thiab cov kev xav tau ntawm kev tuag, annealing, tempering thiab lwm yam txheej txheem kev kho cua sov yog siv los txhim kho cov qauv, tshem tawm cov qauv tsis xws luag ntawm forging thiab dawb paug, tom qab ntawd txhim kho kev ua haujlwm.Tom qab kev npaj kom zoo thaum tshav kub kub kev kho mob ntawm high carbon alloy steel tuag, lub network carbide yuav raug tshem tawm, uas yuav ua rau cov carbide spheroidized thiab refined, thiab kev faib uniformity ntawm carbide yuav nce.Qhov no yog qhov tsim nyog los xyuas kom meej quenching, tempering zoo, txhim kho lub neej kev pab cuam ntawm pwm.

1. Quenching thiab tempering.Qhov no yog qhov txuas tseem ceeb hauv kev kho cua sov tuag.Yog hais tias overheating tshwm sim thaum lub sij hawm quenching cua sov, nws yuav tsis tau tsuas yog ua rau brittleness ntau dua ntawm lub workpiece, tab sis kuj yooj yim rau deformation thiab tawg thaum lub sij hawm txias, uas yuav cuam tshuam rau lub neej kev pab cuam ntawm pwm.Cov txheej txheem tshwj xeeb ntawm kev kho cua sov yuav tsum tau tswj nruj me ntsis thiab kev kho cua sov yuav tsum tau txais.Tempering yuav tsum tau ua nyob rau hauv lub sij hawm tom qab quenching, thiab raws li cov kev cai kom txais yuav txawv tempering txheej txheem.
2. Kev ntxhov siab-relieving annealing.Cov tuag yuav tsum raug kev nyuaj siab-relieving annealing kev kho mob tom qab rough machining, thiaj li yuav tshem tawm cov kev ntxhov siab nyob rau hauv los ntawm ntxhib machining, thiaj li tsis txhob overdeformation los yog tawg los ntawm quenching.Rau cov neeg tuag uas xav tau kev ua haujlwm siab, nws tseem yuav tsum tau ua kom muaj kev ntxhov siab-relieving tempering tom qab sib tsoo, uas yog qhov zoo rau kev ruaj khov ntawm qhov tseeb tuag thiab txhim kho lub neej kev pab cuam.
Qhib qhov tus nqi ntawm lub nplhaib tuag
Yog tias qhov qhib qhov ntawm lub nplhaib tuag siab dhau lawm, qhov ua tau ntawm lub nplhaib tuag tawg yuav nce ntxiv.Vim tias qhov sib txawv ntawm kev kho cua sov thiab cov txheej txheem, yuav muaj qhov sib txawv loj ntawm txhua lub nplhaib tuag cov chaw tsim khoom.Feem ntau, peb cov pellet zeb tuag tuaj yeem txhim kho qhov qhib qhov ntsuas los ntawm 2-6% ntawm lub hauv paus ntawm domestic thawj-chav kawm hom pwm, thiab tuaj yeem ua kom muaj kev pabcuam lub neej ntawm lub nplhaib pwm.
Pellet zeb tuag hnav
tej thickness thiab lub zog yog txo mus rau lub point uas nws tsis tuaj yeem dais lub siab ntawm granulation, tawg yuav tshwm sim.Nws raug nquahu tias thaum lub nplhaib tuag yog hnav mus rau theem uas sib npaug rau cov menyuam plhaub zawj, lub nplhaib tuag yuav tsum tau hloov lub sijhawm.
Thaum lub pellet zeb tuag nyob rau hauv tus txheej txheem ntawm granulation, tus nqi ntawm cov khoom mus rau hauv lub pellet zeb tuag yuav tsis tau khiav ntawm 100%. ua rau lub nplhaib tuag.Peb pom zoo kom tswj ntawm 75-85% ntawm cov load kom ntseeg tau tias lub neej kev pab cuam ntawm lub nplhaib tuag.
Yog tias lub nplhaib tuag thiab cov xovxwm yob yog nias nruj heev, nws yooj yim tawg.Feem ntau, peb xav kom qhov kev ncua deb ntawm lub nplhaib tuag thiab cov xovxwm yob tswj ntawm 0.1-0.4mm.
khoom noj khoom haus
Nws yooj yim tawg thaum cov khoom siv tawv xws li hlau tshwm hauv cov khoom pelleting.
Installation ntawm lub nplhaib tuag thiab pelleting tshuab
Lub installation ntawm lub nplhaib tuag tsis nruj, yuav muaj qhov sib txawv ntawm lub nplhaib tuag thiab lub tshuab pelleting, thiab lub nplhaib tuag tawg kuj yuav tshwm sim hauv cov txheej txheem ntawm pelleting.
Tom qab kev kho cua sov, lub nplhaib tuag yuav deformed heev.Yog tias tsis kho, lub nplhaib tuag yuav tawg thaum siv.
Thaum lub tshuab pelleting nws tus kheej muaj qhov tsis xws luag, xws li lub ntsiab ncej ntawm lub tshuab pelleting co.
