2. kev tiv thaiv zoo heev: cov hlau ductile ua rau muaj kev tiv thaiv zoo heev, ua rau nws zoo tagnrho rau cov ntawv thov uas muaj kev sib txhuam, kev puas tsuaj, lossis kev raug rau qhov chaw ib puag ncig hnyav. cov cuab yeej no ua rau lub neej ntev ntawm cov khoom, thaum kawg txo cov nqi cuam tshuam nrog kev saib xyuas thiab hloov pauv.

3. kev siv tshuab zoo: thaum cov hlau ductile yog cov hlau uas tawv, lawv kuj yooj yim rau kev siv tshuab. qhov kev sib npaug ntawm lub zog thiab kev ua haujlwm ua rau muaj cov txheej txheem engineering meej, kom ntseeg tau tias cov khoom tuaj yeem tsim tau raws li cov lus qhia tseeb.

4. kev tiv thaiv corrosion: cov khoom siv tshuaj lom neeg ntawm en-gjs ductile hlau ua rau nws muaj kev tiv thaiv corrosion, tshwj xeeb tshaj yog thaum piv rau lwm cov ntaub ntawv ferrous. thaum cov txheej ntxiv tuaj yeem txhim kho cov khoom no, cov khoom siv hauv paus muab lub hauv paus ruaj khov rau kev ua haujlwm ntev.

cov txiaj ntsig ntawm kev siv en-gjs ductile iron bars**

1. kev ua tau ntau yam: en-gjs ductile hlau tuav tuaj yeem siv rau ntau yam kev siv, xws li cov khoom siv tsheb mus rau cov ntaub ntawv tsim kho. qhov kev ua tau ntau yam no ua rau lawv yog qhov kev xaiv zoo rau cov engineers uas tab tom nrhiav kev daws teeb meem tag nrho.

2. kev siv nyiaj tsim nyog: vim lawv lub neej ua haujlwm ntev thiab txo qhov xav tau kev saib xyuas, kev siv cov hlau ductile tuaj yeem ua rau kev txuag nyiaj ntau dhau sijhawm. ntxiv rau, lawv muaj ntau qhov ntau thiab tsawg thiab cov duab txhais tau tias muaj kev xaiv rau yuav luag txhua qhov project yam tsis tas yuav tsum tau kho kim.

3. kev nyab xeeb: qhov ductility ntawm gjs ua kom ntseeg tau tias cov qauv tsis tshua muaj kev puas tsuaj loj heev piv rau cov ntaub ntawv brittle. qhov no ua rau lawv haum rau cov ntawv thov tseem ceeb qhov twg kev nyab xeeb yog qhov tseem ceeb, xws li hauv cov qauv lossis cov hlab ntsha siab.

4. kev ruaj khov: cov hlau ductile tuaj yeem rov ua dua tshiab yam tsis poob qhov zoo, ua raws li cov kev coj ua tsim khoom ruaj khov. Los ntawm kev xaiv en-gjs ductile hlau bars, cov tuam txhab tuaj yeem pab txhawb kev txo cov khib nyiab hauv kev lag luam thiab txhawb kev saib xyuas ib puag ncig.

cov ntawv thov ntawm en-gjs ductile hlau tuav **

cov ntawv thov ntawm en-gjs ductile hlau tuav yog dav thiab ntau yam:

- kev lag luam tsheb: cov tuav no feem ntau siv rau hauv kev tsim cov khoom siv ncua, crankshafts, thiab lwm yam khoom siv vim lawv lub zog siab-rau-qhov hnyav piv thiab kev ua kom muaj zog.

- kev tsim kho: siv rau hauv kev tsim cov kav dej, cov ntoo, thiab cov kev txhawb nqa, qhov ruaj khov ntawm cov hlau ductile ua kom ntseeg tau tias cov tsev thiab cov chaw tsim kho vaj tse tuaj yeem tiv taus cov khoom hnyav.

- tshuab thiab khoom siv**: ntau lub tshuab kev lag luam siv cov hlau en-gjs ductile hauv lawv cov thav duab, casings, thiab iav, vim lawv txoj kev tiv taus kev hnav thiab kev siv tshuab tau.
