Nodular cam khwb cia hlau steel yeeb nkabs yog qhov tseem ceeb ntawm cov kav dej hlau, uas muaj cov ntsiab lus ntawm cov hlau thiab cov khoom ntawm cov hlau, yog li lawv lub npe. Graphite nyob rau hauv ductile hlau kav muaj nyob rau hauv ib tug kheej kheej daim ntawv, nrog ib tug dav dav ntawm 6-7 qib. Nyob rau hauv cov nqe lus ntawm zoo, spheroidization theem ntawm cam khwb cia hlau kav yuav tsum tau tswj nyob rau hauv 1-3 theem, nrog ib tug spheroidization tus nqi ntawm ≥ 80%. Yog li ntawd, cov khoom siv ntawm cov khoom siv nws tus kheej tau txhim kho, muaj cov ntsiab lus ntawm cov hlau thiab cov khoom ntawm cov hlau. Tom qab annealing, microstructure ntawm cov kav hlau hlau yog ferrite nrog ib qho me me ntawm pearlite, uas muaj cov khoom siv zoo, yog li nws tseem hu ua cam khwb cia.hlau steel kav.

Nodular cam khwb cia hlau yeeb nkab (5)

1.Internal Pressure Resistance: Cov yeeb nkab hlau muaj lub zog ntawm cov hlau nrog lub toughness ntawm hlau nws yog qhov kev xaiv zoo tshaj plaws. Kev ua haujlwm siab yog siv, thiab qhov tawg siab yog txog li peb zaug ntawm kev ua haujlwm siab.

2.External Pressure Resistance: Kev kub siab tiv thaiv txhais tau tias tsawg dua cov ntaub pua chaw tshwj xeeb lossis cov ntaub ntawv yuav tsum tau ua, ua rau koj lub installation yooj yim dua thiab siv nyiaj ntau dua.

3.Inner Anti-Corrosion Layer: Cov kav dej yog centrifugally lined nrog cement mortar raws li ISO 4179 rau kev siv dej haus. Cov txheej txheem no ua rau lub ntsej muag du, tawv tawv uas tiv thaiv cov dej haus thiab tsis flake lossis xeb.

4.Protective Layer: Zinc txau (≥130 g / m², ISO 8179) thiab chlorinated Resin xim pab kom muaj kev tiv thaiv zoo dua corrosion. Kev xaiv tuab zinc txheej lossis zinc-aluminium txheej tuaj yeem muab tau raws li cov neeg siv khoom tshwj xeeb.

Nta

Cov yeeb nkab hlauyog ib hom cam khwb cia hlau yeeb nkab. Cov kav hlau kav hlau yog tsim los ntawm qib 1-3 ntawm spheroidization (Spheroidizationrate> 80%) los txhim kho cov khoom siv kho tshuab los ntawm kev ua kom zoo dua ntawm cov hlau thiab lub zog ntawm cov hlau. Cov yeeb nkab annealed muaj cov qauv ferrite nrog me me ntawm pearlite, thiab muaj kev tiv thaiv corrosion zoo, ductility, sealing kev ua tau zoo thiab yooj yim rau installation. Lawv nrhiav kev siv dav hauv dej, xa hluav taws xob, thiab roj tsheb thauj mus los hauv nroog thiab kev lag luam.

Spherical graphite yog puag ncig los ntawm matrix ntawm ferrite thiab pearlite. Tus nqi ntawm pearlite rau ferrite nyob ntawm qhov loj ntawm cov yeeb nkab thiab nws cov kev xav tau elongation: rau feem ntau, cov kav dej me me muaj pearlite ≤20% thiab cov kav dej loj ≈25%.

Daim ntawv thov

Cov kav dej hlau hauv qhov ntau thiab tsawg ntawm 80 mus rau 1600 hli yog siv tau rau hauv cov dej haus (BS EN 545) thiab hauv cov kav dej phwj (BS EN 598). Lawv sib koom ua ke yooj yim, nruab rau hauv txhua qhov huab cua, feem ntau tsis muaj qhov tshwj xeeb rov qab, thiab muab qhov zoo tshaj plaws ntawm kev nyab xeeb nrog kev yooj yim txaus los tiv thaiv kev txav hauv av, equipping lawv zoo kawg nkaus rau kev siv ntau yam kev siv kav dej.
