Cov kav hlau kav hlau

Cov yeeb nkab hlau yog hais txog kev siv ntau tshaj 18 casting kub hlau tom qab qhov sib ntxiv ntawm spheroidizing tus neeg sawv cev, los ntawm cov centrifugal ductile hlau tshuab high-speed centrifugal casting rau hauv cov yeeb nkab, hu ua cov yeeb nkab hlau, cov yeeb nkab hlau yeeb nkab thiab ductile casting. cev. Feem ntau yog siv rau kev sib kis ntawm cov kais dej, yog qhov kev xaiv zoo tshaj plaws ntawm cov khoom siv hauv cov kav dej.

Cov ntsiab lus ntawm cov yeeb nkab hlau yog cov yeeb nkab hlau, vim tias cov yeeb nkab hlau yeeb nkab muaj cov ntsiab lus ntawm cov hlau, kev ua haujlwm ntawm cov hlau, yog li muaj lub npe no. Graphite nyob rau hauv nodular cam khwb cia hlau kav muaj nyob rau hauv ib tug kheej kheej daim ntawv, thiab qhov loj ntawm lub dav graphite yog 6-7. Nyob rau hauv cov nqe lus ntawm zoo, nodularization qib ntawm cam khwb cia hlau yeeb nkab yuav tsum tau tswj mus rau 1-3 qib, thiab cov nodularization tus nqi yog ntau tshaj los yog sib npaug rau 80%, yog li cov neeg kho tshuab cov khoom ntawm cov khoom nws tus kheej tau zoo lawm. , nrog cov ntsiab lus ntawm hlau thiab kev ua haujlwm ntawm steel. Tom qab annealing ductile hlau yeeb nkab, nws cov qauv metallographic yog ferrite ntxiv rau ib qho me me ntawm pearlite, txhua yam khoom zoo, yog li nws tseem hu ua cam khwb cia hlau steel yeeb nkab.

Cov txheej txheem rau kev sib tsoo ntawm lub raj tuag
1.Raws li lub nominal txoj kab uas hla ntawm lub raj tuag, cov kev txhawb nqa cov menyuam yog hloov kho rau qhov predetermined spacing raws li lub tshuab scale.
2. Muab lub raj tuag rau hauv av rau ntawm cov menyuam txhawb nqa.
3. Tshawb xyuas thiab txiav lub log sib tsoo. Thiab raws li qhov tshwj xeeb ntawm lub raj pwm xaiv nrog nws cov sib tsoo sib tsoo pas nrig thiab lub taub hau sib tsoo
Kho lub puab sib tsoo ntev txwv thaiv raws li pwm specification.
4. Ua ntej grind lub raj tuag 5 mus rau 6 zaug, thiab tom qab ntawd xyuas thiab ntsuas lub taper ntawm lub qhov hauv lub raj tuag thiab qhov loj ntawm lub qhov (socket)
5. Case, txhua qhov sib tsoo yog 0.2mm. Thaum lub puab lub qhov taper thiab loj raws li qhov yuav tsum tau, tsis siv neeg sib tsoo; Yog hais tias lub taper thiab bus straightness tsis tau raws li qhov yuav tsum tau, nws yog tsim nyog los siv segmented sib tsoo
Peel.
6. Thaum sib tsoo lub taper, los ntawm lub qhov (socket) mus rau lub qhov (socket), txhua 500 ~ 600mm yog ib qho kev nce ntxiv.
7. Thaum sib tsoo, lub taub hau sib tsoo yuav tsum khiav zoo thiab tsis txhob ntaus. Yog tias kev sib tsoo tshwm sim, lub log sib tsoo yuav tsum tau maj mam tuav.
8. Thaum lub sij hawm ua, lub puab qhov loj yuav tsum tau ntsuas txhua lub sij hawm, lub qhov (socket) yuav tsum tau ntsuas nyob rau hauv peb seem nyob rau hauv qhov ntau ntawm 0~500mm, lub qhov (socket) yuav tsum ntsuas ntawm 500 hli. , txoj kab uas hla txawv ntawm lub puab lub qhov yuav tsum tsis txhob tsawg tshaj li 0.5 hli, thiab qhov luaj li cas yuav tsum tau guaranteed nyob rau hauv tus txheej txheem ntawm kev tsim qauv.
9. Siv phau ntawv sib tsoo lub log kom zom lub qhov (socket) kawg. Ua tib zoo saib kom lub qhov (socket) tsis hloov pauv thaum sib tsoo
10. Tom qab sib tsoo, qhov roughness ntawm lub puab lub qhov yog 3.2-6.8, thiab cov nto yog dawb oxide thiab lwm yam impurities.
11. Thaum lub raj pwm siv tom qab los yog cov lus pom zoo tau ceeb toom, lub puab phab ntsa ntawm lub raj pwm yuav tsum nce qhov sib tsoo los yog qhov sib tsoo dot yuav tsum tau rov ua dua los txhim kho cov dej xau ntawm lub raj.
