Cov laj thawj rau kev tawg ntawm lub nplhaib pwm yog qhov nyuaj thiab yuav tsum tau txheeb xyuas kom meej;Txawm li cas los xij, lawv tuaj yeem raug sau tseg rau hauv cov laj thawj hauv qab no:
1. Ua los ntawm cov khoom siv nplhaib tuag thiab qhov tsis zoo
1)Cov khoom siv hauv lub nplhaib tuag yog ib qho laj thawj tseem ceeb.Tam sim no, Suav nplhaib tuag tsuas yog siv 4Cr13 thiab 20CrMnTid, uas yog qhov ruaj khov.Txawm li cas los xij, muaj cov tuam txhab tsim khoom sib txawv.Rau cov khoom siv tib yam, yuav muaj qee qhov sib txawv ntawm cov kab ke, uas 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 high-alloy cuab tam steel pwm, feem ntau yuav tsum tau rau cov metallographic qauv xws li carbide tis nyob rau hauv cov khoom.Lub forging kub ntau kuj yuav tsum tau nruj me ntsis tswj, qhov tseeb cua sov specifications yuav tsum tau formulated, yog forging txoj kev yuav tsum tau saws, thiab qeeb txias los yog raws sij hawm annealing tom qab forging yuav tsum tau ua.Cov txheej txheem tsis tu ncua tuaj yeem yooj yim ua rau tawg ntawm lub nplhaib tuag lub cev.
3)Kev npaj rau kev kho cua sov.Nyob ntawm cov khoom thiab cov kev xav tau ntawm cov pwm, kev npaj kho cua sov txheej txheem xws li annealing thiab quenching thiab tempering yog siv los txhim kho cov qauv, tshem tawm cov txheej txheem tsis xws luag hauv forging thiab blanks, thiab txhim kho cov txheej txheem.Tsim nyog npaj kev kho cua sov ntawm high carbon alloy pwm steel yuav tshem tawm network carbides, spheroidize thiab refine carbides, thiab txhawb uniform carbide faib.Qhov no yuav pab xyuas kom zoo ntawm quenching thiab tempering thiab nce lub neej ntawm pwm.
2. Nplhaib tuag kev kho cua sov
1)quenching thiab tempering.Qhov no yog qhov txuas tseem ceeb hauv kev kho pwm kub.Yog hais tias overheating tshwm sim thaum lub sij hawm quenching thiab cua sov, nws yuav tsis tsuas ua rau brittleness ntau dua ntawm lub workpiece, tab sis kuj yooj yim ua rau deformation thiab tawg thaum lub sij hawm txias, heev cuam tshuam lub neej ntawm pwm.Cov txheej txheem kev kho cua sov yuav tsum tau tswj nruj me ntsis thiab kev kho cua sov yuav tsum tau siv.Tempering yuav tsum tau nqa tawm nyob rau hauv lub sij hawm tom qab quenching, thiab txawv tempering txheej txheem yuav tsum tau saws raws li cov kev cai.cov
2)kev nyuaj siab nyem annealing.Cov pwm yuav tsum raug kev ntxhov siab rau kev ntxhov siab tom qab kev ua haujlwm ntxhib kom tshem tawm cov kev ntxhov siab sab hauv los ntawm kev ua haujlwm ntxhib kom tsis txhob muaj ntau dhau deformation lossis tawg los ntawm quenching.Rau cov pwm uas yuav tsum tau muaj siab precision, yuav tsum tau muaj kev ntxhov siab kho tempering tom qab sib tsoo, uas yog qhov zoo rau stabilizing qhov raug ntawm pwm thiab ua rau nws cov kev pab cuam lub neej.
3. Qhib piv ntawm lub nplhaib pwm
1)Yog tias qhov qhib ntawm lub nplhaib tuag siab dhau lawm, qhov ua tau ntawm lub nplhaib tuag tawg yuav nce ntxiv.Txhua lub nplhaib pwm tsim yuav muaj qhov sib txawv loj vim qhov sib txawv ntawm kev kho cua sov thiab txheej txheem.Feem ntau, peb lub tuam txhab cov khoom tuaj yeem nce tus nqi qhib los ntawm 2-6% ntawm lub hauv paus ntawm domestic thawj-chav hom pwm pwm, thiab tuaj yeem ua kom muaj kev pabcuam lub neej ntawm lub nplhaib pwm.
4. Ntiv nplhaib tuag hnav
1)Thaum lub nplhaib tuag yog hnav rau qee qhov tuab thiab lub zog raug txo mus rau qhov chaw uas nws tsis tuaj yeem tiv taus lub siab ntawm granulation, tawg yuav tshwm sim.Nws raug nquahu kom hloov lub nplhaib tuag rau lub sijhawm thaum lub nplhaib tuag tau hnav mus rau qhov chaw uas lub siab cov menyuam zawj yog dej ntws.
5. Siv lub nplhaib tuag
1)Thaum lub sij hawm granulation txheej txheem ntawm lub nplhaib tuag, tus nqi ntawm cov khoom nkag tsis tuaj yeem tso cai rau kev khiav hauj lwm ntawm 100% load vim tias qhov siab granulation tso tawm ntawm lub nplhaib tuag nws tus kheej.Xws li kev ua haujlwm ntev thiab kev siv siab yuav ua rau tawg ntawm lub nplhaib tuag..Peb pom zoo kom tswj lub load ntawm 75-85% kom ntseeg tau tias lub neej kev pab cuam ntawm lub nplhaib tuag.
2)Yog hais tias lub nplhaib tuag thiab lub siab rau cov menyuam raug nias nruj heev, kev tawg yooj yim tuaj yeem tshwm sim.Feem ntau, peb xav kom qhov kev ncua deb ntawm lub nplhaib tuag thiab lub siab rau cov menyuam yuav tsum tau tswj ntawm 0.1-0.4mm.
6. Khoom noj khoom haus
1) Kev tawg yuav tshwm sim ntau dua thaum cov khoom tawv xws li cov hlau thaiv tshwm hauv cov ntaub ntawv granulated.
7. Nplhaib tuag installation thiab granulator teeb meem
1) Lub nplhaib tuag tsis tau ntsia nruj thiab muaj qhov sib txawv ntawm nws thiab cov granulator.Lub nplhaib tuag kuj tseem tuaj yeem tawg thaum lub sijhawm txheej txheem granulation.
2) Tom qab kev kho cua sov, lub nplhaib pwm yuav deformed heev.Yog tias tsis kho, lub nplhaib pwm yuav tawg thaum siv.
3) Thaum lub granulator nws tus kheej tsis zoo, xws li lub ntsiab ncej ntawm granulator co, thiab lwm yam.
