1. Txheeb xyuas cov qauv
(1) qhov noNpauj Npaim Valvemuaj cov khoom qab zib ncig-zoo li tus qauv, cov kab noj hniav sab hauv txuas nrog thiab 8 qhov kev sib txuas lus, sab saum toj φ620 qhov sib txuas lus nrog cov kab noj hniav sab hauv, thiab tus so ntawm lubib lub dab tsi uas qhib thiab kawKaw, cov xuab zeb tseem ceeb los kho thiab yooj yim rau deform. Ob leeg lub pa thiab kev ntxuav ntawm lub kab noj kab noj kab noj hniav coj muaj teeb meem loj, raws li qhia hauv daim duab 1.
Lub phab ntsa tuab ntawm cov nrib sib txawv heev, cov phab ntsa siab tshaj plaws txog 380mm, thiab qhov tsawg kawg nkaus phab ntsa tuab tsuas yog 36 hli. Thaum lub casting yog solorified, qhov kub qhov sib txawv yog yooj yim tsim shrinkities thiab shrinkage porcosities tau yooj yim tsim cov khoom tawg, uas yuav ua rau cov dej seem hauv qhov kev xeem hydraulic.
2. Txheej Txheem Tsim:
(1) Cov tog ntu muaj nyob hauv daim duab 1. Muab xaus rau lub taub hau ntawm cov xuab zeb tseem ceeb, thiab kev txav mus los ntawm cov xuab zeb tseem ceeb thaum lub thawv tau muab dua. Lub cev ruaj khov, qhov ntev ntawm lub cantilever tub ntxhais lub taub hau ntawm ob lub qhov muag tsis pom tseeb ntawm lub taub hau tseem ceeb yog qhov tseeb tias cov xuab zeb tseem tsau thiab ruaj khov.
Ib nrab kaw lub cev yog saws, σf sab hauv: × 100 × 100 × 100 × 100 × 80 × 100 × 100 × 100 Cov khiav, thiab 12 lub raj raj nrog lub taub sab hauv ntawm Ofer rau hauv qab ntawm cov txheej txheem dej hauv qab ntawm cov kab hauv qab, raws li qhia hauv daim duab 2 essence
(3) Qhov chaw 14 ∮20 kab noj hniav cua qhov nyob rau hauv lub puab tsaig sab saud, thiab siv cov sandagitions txias thiab ntau qhov chaw txias Qhov luaj li cas ntawm cov xuab zeb yog 3600 × 1000-1000 1000 10001000 / 600mm, thiab nws yog welded nrog kom paub meej lub zog thiab rigidity, raws li qhia hauv daim duab 3.
3. Cov txheej txheem tswj
(1) Ua Qauv: Ua qauv ua qauv, siv Aly50 × 50mm qauv muaj zog los cuam tshuam txog cov kab ke ntawm cov kab ke
Core Tsim: Cov xuab zeb tub ntxhais tau muab faib ua 8 qhov sib npaug ntawm 8 kev txhawb nqa tus tav, uas txuas nrog rau hauv nruab nrab. Tsis muaj lwm yam kev txhawb nqa thiab kev tso tseg tsuas yog lub taub hau nruab nrab tub ntxhais. Yog hais tias cov xuab zeb tseem ceeb tsis tuaj yeem tsau thiab kev tso pa, cov xuab zeb tseem ceeb thiab cov pa huab cua yuav tshwm sim tom qab pouring. Vim tias qhov chaw tag nrho ntawm cov xuab zeb tseem ceeb yog loj, nws tau muab faib ua yim ntu. Nws yuav tsum muaj lub zog txaus thiab cov tsis ntseeg kom ntseeg tau tias cov xuab zeb tseem ceeb yuav tsis raug puas tsuaj tom qab cov pwm tso, thiab yuav tsis raug puas tom qab pouring. Deformation tshwm sim, yog li kom ntseeg tau tias lub phab ntsa uas tuab ntawm lub casting. Vim li no, peb tshwj xeeb tau ua cov pob txha txheem tshwj xeeb, thiab khi nws ntawm cov pa tub sab ua kom muaj cov roj txheem ntawm cov xuab zeb thaum ua cov tub ntxhais. Raws li qhia hauv daim duab 4.
(4) Kaw lub npov: xav tias nws yog qhov nyuaj kom ntxuav cov xuab zeb nyob rau hauv lub puab txheej yog txhuam hniav ntawm tus neeg npau taws 45-55), thiab thawj txheej tau pleev xim thiab hlawv. Tom qab ziab, pleev xim rau txheej thib ob nrog cov xim hlau cawv (baume degree 35-45) kom tiv thaiv cov camting los ntawm cov xuab zeb thiab sintering, uas tsis tuaj yeem raug ntxuav. Tus tub ntxhais lub taub hau yog dai rau ntawm φ200 steel yeeb nkab ntawm cov pob txha tseem ceeb ntawm cov ntsia hlau sab saud thiab tshawb xyuas seb puas muaj ib feem ntawm phab ntsa.
4. Melting thiab pouring txheej txheem
(1) Siv Benxi Low-P, S, TI High-Zoo Q14 / 16 # npua hlau, thiab ntxiv nws ntawm qhov sib piv ntawm 40% ~ 60%; Cov kab kawm xws li P, S, Kb, thiab lwm yam raug tso cai thiab roj ntxiv, qhov sib ntxiv yog 25% ~ 40%; Qhov rov qab xa rov qab yuav tsum tau ntxuav los ntawm kev txhaj tshuaj tiv thaiv ua ntej siv kom muaj kev huv ntawm kev them nqi.
(2) Lub ntsiab tiv thaiv lub cub hluavtaws tau.
(3) Kev Kho Mob Hauv Inoculation: Tsawg-magulationium thiab qis-tsawg-lub ntiaj teb spheridesizers siv, thiab qhov sib ntxiv yog 1.0% ~ 1.2%. Cov tshuaj yaug txoj kev sib xyaw ua ke sib xws, 0.15% ntawm ib-zaug inoculation yog them rau ntawm cov pob zeb hauv qab ntawm pob, thiab lub spHeroidization ua tiav. Tom qab ntawd yog tom qab ntawd ua tiav rau theem nrab inoculation ntawm 0.35%, thiab txaus inoculation ntawm 0.15% yog nqa tawm thaum pouring.
(5) Tsawg tus txheej txheem nrawm nrawm nrawm nrawm nrawm yog saws, cov nchuav kub yog 1320 ° C ~ 1340 ° C, thiab lub sijhawm psing yog 70 ~ 80s. Cov hlau molten tsis tuaj yeem cuam tshuam tsis tau thaum lub sijhawm nchuav, thiab lub khob ci ci yog ib txwm muaj pa roj thiab suav nrog kev sib koom ua ke. kab noj hniav.
5. Cov khoom siv ntsuas ntsuas
(1) Kuaj lub zog tensile ntawm cam khwb cia: 485mpa, elongation: 15%, brinell hardness HB187.
(2) Tus nqi sib tw yog 95%, qhov loj me ntawm graphite yog qib 6, thiab cov hlaws yog 35%. Daim hlau ntsuas yog duab yog muaj nyob hauv daim duab 5.
(3) Tsis muaj cov xwm txheej kaw cia tau pom nyob hauv tus Ut thiab MT theem nrab qhov kom pom ntawm qhov chaw tseem ceeb.
(4) Cov tsos yog tiaj thiab du (saib Daim Duab 6), tsis muaj cov duab tawg, thiab lwm yam, thiab qhov ntev ua tau raws li cov duab kos.
(6) 20kg / cm2 hydraulic ntsuam xyuas tom qab ua tsis tau qhia ib qho xau
6. Xaus
Raws li cov qauv kev teeb tsa ntawm lub npauj npaim no, qhov teeb meem ntawm kev ntxuav cov xuab zeb, kev tsim cov xuab zeb loj thiab kev siv cov zirconium-raws li txheej txheej. Qhov kev teeb tsa ntawm cov qhov cua qhov zam kev zam qhov ua tau ntawm cov hws hauv casings. Los ntawm cov cub hluav taws xob tswj hwm thiab khiav tawm system, ua npuas ncauj ceramic lim cov vijtsam thiab cov ceramic Inchical technology yog siv los xyuas kom meej cov hlau ntawm Molten. Tom qab kev kho mob rau ntau yam, cov qauv ntawm lub ntsej muag ntawm cov chaw ua haujlwm thiab ntau yam kev ua tau zoo tau mus txog cov qauv uas yuav tsum tau ua cov neeg yuav khoom
