Cam khwb cia hlau steel yeeb nkab, hauv qhov essence, hais txog cov yeeb nkab hlau. Nws cov khoom tseem ceeb yog carbon, silicon, manganese, sulfur, phosphorus thiab magnesium. Cov ntsiab lus tseem ceeb no yog qhov tseem ceeb lav rau nws los ua cov yeeb nkab zoo. Cov kav dej hlau tau txais lub npe no vim tias lawv muaj cov ntsiab lus ntawm cov hlau thiab cov khoom ntawm cov hlau. Graphite nyob rau hauv cov kav hlau kav muaj nyob rau hauv daim ntawv kheej kheej, thiab qhov loj ntawm graphite feem ntau yog 6-7 qib. Rau qhov kev xav tau zoo ntawm cov kav hlau cam khwb cia, qib spheroidization yuav tsum tau tswj ntawm 1-3 qib, thiab tus nqi spheroidization yuav tsum ncav cuag ntau dua 80 feem pua. Yog li ntawd, cov khoom siv ntawm cov khoom nws tus kheej tau zoo dua qub, uas tsis tsuas yog muaj cov ntsiab lus ntawm cov hlau, tab sis kuj muaj cov khoom ntawm cov hlau.
Tom qab annealing, metallographic qauv ntawm cov yeeb nkab annealed ductile hlau yog tsuas yog tsim los ntawm ferrite thiab ib qho me me ntawm pearlite, uas muaj cov khoom siv zoo, yog li nws tseem hu ua cam khwb cia hlau yeeb nkab. Cov kav dej no muaj kev ua haujlwm zoo los tiv thaiv corrosion, zoo ductility, zoo sealing nyhuv, thiab yooj yim installation. Nws yog tsuas yog siv rau cov khoom siv dej, roj xa mus, roj tsheb thauj mus los, thiab lwm yam hauv nroog thiab kev lag luam thiab kev lag luam mining. Nws yog thawj qhov kev xaiv rau cov kav dej thiab muaj kev ua haujlwm siab.

2. Cov khoom zoo
Lub zog & Toughness
Ductile hlau yeeb nkab muaj lub zog zoo thiab toughness. Kev faib tawm tsis sib xws thiab cov duab kheej kheej ntawm graphite spheres ua rau cov yeeb nkab kom nqus tau thiab cuam tshuam kev ntxhov siab, txo qhov kev pheej hmoo ntawm pob txha thiab tawg.
Corrosion Resistance
Cov kav dej hlau feem ntau yog coated los yog lined kom lawv cov corrosion kuj thiab tiv thaiv cov kav dej los ntawm corrosion thiab puas.
Yooj yim Installation
Muaj ntau txoj kev sib txuas rau cov kav hlau txuas, nrog rau kev sib txuas flange, roj hmab sealing nplhaib kev sib txuas thiab xov txuas, thiab lwm yam, thiab kev teeb tsa kuj yooj yim.
Hnav Resistance
Cov yeeb nkab hlau muaj qhov hnav zoo heev, tshwj xeeb tshaj yog tsim rau cov ntawv thov uas yuav tsum tau nquag ntws thiab kev thauj mus los ntawm cov tshuaj abrasive.
Kev lag luam
Piv nrog rau lwm cov ntaub ntawv, tus nqi ntawm cov yeeb nkab hlau yeeb nkab yog qis dua, thiab nws muaj cov nqi zoo. Tsis tas li ntawd, nws lub neej ntev thiab kev saib xyuas tsis tu ncua txo cov nqi khiav lag luam tag nrho.
3. Daim ntawv thov
1. Cov kav dej:Cov kav dej kav dej yog siv dav hauv cov kav dej hauv nroog. Nws cov corrosion kuj thiab abrasion tsis kam tso cai rau nws tiv taus siab thiab nruam dej ntws, thaum tseem tiv thaiv qhov yaig ntawm corrosive yam xws li chlorides thiab sulfates hauv dej. Cov yeeb nkab hlau tseem muaj qee qhov yooj yim los daws cov kev ntxhov siab los ntawm ib puag ncig xws li av qeeg lossis hloov av.
2. Cov kav dej phwj tuaj kho:Cov kav hlau kav hlau yog siv dav hauv cov kav dej phwj tuaj. Vim nws tsis kam tiv thaiv corrosion thiab hnav, nrog rau nws muaj peev xwm tiv taus siab thiab hnyav, cov kav hlau hlau tuaj yeem thauj cov dej phwj tuaj thiab cov dej khib nyiab, thiab tseem tuaj yeem siv rau kev sib txuas ntawm cov kav dej phwj thiab cov khoom siv kho mob sludge.
3. Roj & Nthuav Roj Pipelines:Cov kav hlau kav hlau muaj cov ntawv thov tseem ceeb hauv cov roj thiab cov roj hluav taws xob sib kis. Nws lub zog thiab kev tiv thaiv corrosion ua rau nws xaiv cov kav dej txhim khu kev qha rau kev xa cov kua dej siab thiab cov pa roj. Cov kav dej hlau kuj tseem tuaj yeem tiv taus siab thiab cov khoom siv thauj khoom thaum thauj mus los hauv av.
4. Cov kav dej muaj:Cov kav hlau kav hlau ua lub luag haujlwm tseem ceeb hauv ntau daim ntawv thov hauv kev lag luam. Piv txwv li, nws tuaj yeem siv rau hauv cov kav dej rau kev thauj cov coal slurry ore, sib tsoo cov ntaub ntawv thiab lwm yam khoom siv. Cov kav dej hlau kuj tuaj yeem siv rau hauv cov dej txias, kev kho dej khib nyiab thiab kev xa tshuaj, thiab lwm yam.
5. Nroog infrastructure tej yaam num:Cov kav dej hlau yog siv rau hauv cov phiaj xwm hauv nroog, xws li txoj kev tso dej, cov kav dej, cov dej tua hluav taws, thiab lwm yam. Nws cov kav ntev thiab cov khoom siv kho tshuab tau lav qhov kev ruaj ntseg thiab kev ntseeg siab ntawm qhov system.
