Cam khwb cia hlau yog ib qho hlau ntawm cov hlau nrog me me ntawm cov pa roj carbon. Qee zaum alloying additives tseem qhia rau hauv cov khoom muaj pes tsawg leeg, muab nws cov neeg siv khoom ntau dua. Cov ntawv hlau no yog thawj cov khoom siv rau hlau luam hlau ua kom zoo nkauj. Nws yog siv tsis tsuas yog hauv kev tsim cov hlau thiab kev siv tshuab, tab sis tseem siv rau kev tsim khoom ntawm cov khoom kos duab.
Cov Lus Qhia

Cam khwb cia hlau muaj cov txiaj ntsig zoo heev uas ua rau nws haum rau kev tsim cov khoom lag luam rau ntau lub hom phiaj. Cov hlau no pheej yig thiab muaj cov khoom zoo casting zoo heev. Nws kuj muaj lub siab hardness thiab lub zog. Vim li no, cov hlau cam yog dav siv qhov twg cov khoom lag luam ntawm cov duab bizarre xav tau uas tuaj yeem thev taus qhov hnyav. Nws yog siv, piv txwv li, siv rau kev tsim khoom siv cav thiab kev siv lub tshuab lub cev.

Hauv kev tsim kho tshuab, thiaj li hu ua grey cam khwb cia hlau, uas muaj cov graphite, yog siv dav. Cov khoom lag luam ua los ntawm cov hlau no yuav luag tsis muaj qhov cuam tshuam los ntawm kev cuam tshuam ntawm kev ntxhov siab thiab zoo nqus kev co uas tshwm sim los ntawm kev tsuj ntawm lub tshuab thiab tshuab. Grey cam khwb cia hlau yog qhov zoo rau qhov tseem ceeb xws li bushings thiab tshuab txaj.

Qhov tsis tseem ceeb rau cov cam khwb cia hlau hauv kev lag luam tsheb. Nws ua kom ruaj khov thiab hnav-tiv taus cav cov tshuab. Rau kev ntseeg tau ntau dua, cov graphite tshwj xeeb ntxiv rau hauv cov hlau kuj. Qhov ua tau zoo dua cov hlau cam khwb cia kuj tuaj yeem siv rau hauv cov khoom lag luam ntawm diesel crankshafts.

Zas hlau kuj tseem muaj nws thaj chaw ntawm kev siv. Nws muaj cov plhaws zoo heev txawm tias piv rau cov hlau thiab ua tau zoo ntawm qhov kub tsawg. Qhov kev hloov kho ntawm cov hlau no yog siv hauv kev tsim cov khoom tseem ceeb ntawm tsheb laij teb thiab tsheb uas yuav tsum ua haujlwm hauv huab cua hnyav.

Lwm qhov chaw ntawm kev thov ntawm cam khwb cia hlau yog qhov khoom lag luam ntawm cov khoom lag luam huv. Cov kav dej, hluav taws xob, fittings, chav dab dej thiab dab dej yog tsim los ntawm cov hlau no. Txog tam sim no, cam khwb cia hlau da dej yog nyob rau hauv kev thov zoo, uas tau sib txawv los ntawm lub zog loj, kev ntseeg siab, kev coj ua thiab lub caij. Cov khoom lag luam no tuaj yeem pab hauv tsev rau ntau caum xyoo, khaws lawv qhov qub thiab tsis tas yuav hloov chaw.
Kauj Ruam 7
Cam khwb cia hlau yog dav siv rau kev tsim khoom. Feem ntau ntawm cov embankments ntawm St. Petersburg, piv txwv li, tau dai kom zoo nkauj nrog cov ntsiab lus cam khwb cia hlau. Nyob hauv lub nroog ntawm Neva, ib qho tuaj yeem pom cov rooj vag qhib qhib thiab laj kab laj kab ua los ntawm cov hlau no. Muaj kuj tseem cam khwb cia-hlau monuments.
