1. Cov tswv yim sib txawv
Cov yeeb nkab hlau ua los ntawm tshuab yog cov yeeb nkab hlau uas muaj cov dej ntws yooj ywm uas tsim los ntawm cov txheej txheem centrifugal casting. Lub interface feem ntau yog W-hom clamp hom lossis A-hom flange hom qhov (socket).
Cov kav hlau ductile yog cov kav dej uas raug pov los ntawm kev siv lub tshuab centrifugal ductile hlau tom qab ntxiv cov neeg sawv cev nodulizing rau cov hlau molten saum toj no No. 18. Lawv raug xa mus rau cov kav hlau ductile, cov kav hlau ductile hlau thiab cov kav hlau ductile cast. Feem ntau siv rau kev thauj mus los ntawm cov kais dej, nws yog cov khoom siv zoo tagnrho rau cov kav dej dej.
2. Kev ua tau zoo sib txawv
Cov yeeb nkab hlau ductile yog ib hom hlau cam khwb cia, ib qho hlau sib xyaw ua ke ntawm hlau, carbon thiab silicon. Graphite hauv cov hlau ductile muaj nyob rau hauv daim ntawv ntawm spheroids. Feem ntau, qhov loj ntawm graphite yog qib 6-7. Qhov zoo yuav tsum tau tswj qib spheroidization ntawm cov yeeb nkab cam khwb cia rau qib 1-3, yog li cov khoom siv kho tshuab ntawm cov khoom siv nws tus kheej tau zoo dua. Nws muaj lub ntsiab lus ntawm hlau thiab cov khoom ntawm hlau. Cov qauv metallographic ntawm cov yeeb nkab hlau annealed yog ferrite ntxiv rau me me ntawm pearlite, thiab nws cov khoom siv kho tshuab zoo.
Lub neej ua haujlwm ntawm cov kav dej hlau uas ua los ntawm tshuab ntau dua li lub neej xav tau ntawm lub tsev. Nws muaj kev tiv thaiv av qeeg zoo heev thiab siv tau rau kev tiv thaiv av qeeg ntawm cov tsev siab. Nws siv cov qog flange thiab cov nplhaib roj hmab lossis cov nplhaib roj hmab thiab cov clamps hlau tsis xeb kom txuas tau yooj yim. Nws muaj kev sib khi zoo thiab tso cai rau Swings hauv 15 degrees yam tsis muaj kev xau.
Siv cov pwm hlau centrifugal casting. Cov yeeb nkab hlau cam khwb cia muaj cov phab ntsa tuab sib npaug, cov qauv me me, qhov chaw du, thiab tsis muaj qhov tsis zoo ntawm kev cam khwb xws li cov pob liab thiab cov slag. Lub roj hmab interface txo cov suab nrov thiab tsis tuaj yeem hloov pauv rau cov yeeb nkab ntsiag to tshaj plaws, tsim kom muaj ib puag ncig zoo tshaj plaws.
3. Kev siv sib txawv
Cov kav dej hlau cam khwb cia yog tsim rau kev tsim cov dej ntws, cov dej phwj tuaj, kev tsim kho vaj tse, kev ntws dej ntawm txoj kev, cov dej khib nyiab hauv kev lag luam, thiab cov kav dej ua liaj ua teb; cov kav dej hlau cam khwb cia tuaj yeem tsim nyog rau kev nthuav dav axial loj thiab kev hloov pauv thiab kev hloov pauv sab nraud ntawm cov kav dej; cov kav dej hlau cam khwb cia yog tsim rau av qeeg nrog qhov muaj zog ntawm 9 degrees Siv rau hauv cov cheeb tsam hauv qab no.
Cov yeeb nkab hlau ductile feem ntau hu ua centrifugal ductile iron pipe. Nws muaj lub ntsiab lus ntawm hlau thiab kev ua tau zoo ntawm hlau. Nws muaj kev ua tau zoo tiv thaiv xeb zoo heev, ductility zoo, sealing zoo, thiab yooj yim rau nruab. Nws feem ntau yog siv rau kev muab dej, roj xa mus, thiab kev thauj mus los hauv nroog, kev lag luam thiab kev tsuas, roj thiab lwm yam. Nws yog cov yeeb nkab xa dej thiab muaj kev ua tau zoo siab.
