01.Material Composition thiab Properties
Nyob rau hauv cov nqe lus ntawm cov khoom muaj pes tsawg leeg thiab cov khoom, ductile hlau kav yog nrum los ntawm molten hlau nrog ntxiv spheroidizing cov neeg ua hauj, muaj spheroidal graphite, uas ua rau lawv ntau tawv. Tsis tas li ntawd, cov kav hlau kav hlau muaj qhov zoo dua qub hauv kev tiv thaiv tam sim ntawd ntau dua li cov kav dej grey cam khwb cia hlau zoo tib yam, ua rau lawv hloov mus rau cov kev tsim kho nyuaj thiab ntau qhov chaw siv. Tej cam khwb cia hlau kav tsuas yog ua los ntawm cam khwb cia hlau; thaum lawv muaj qee theem ntawm lub zog thiab hnav tsis kam, lawv qhov kev ua tau zoo yog qhov qis dua ntawm cov kav hlau kav hlau.
02.Cov txheej txheem tsim khoom
Los ntawm kev pom kev tsim khoom, cov txheej txheem ntau lawm ntawm cov kav dej hlau muaj xws li spheroidizing kev kho ntawm cov hlau molten, centrifugal casting, annealing, thiab tiv thaiv - kev kho corrosion . Cov txheej txheem no coj cov cuab yeej cuab tam ntawm cov kav hlau hlau ze rau cov kav hlau. Sab hauv thiab sab nraud tiv thaiv- kev kho corrosion ntxiv txhim kho cov yeeb nkab corrosion thiab hnav tsis kam, ua rau lub neej ua haujlwm ntev dua li cov kav hlau cam khwb cia. Cov txheej txheem tsim khoom ntawm cov kav hlau cam khwb cia yog qhov yooj yim, tsis muaj cov kauj ruam xws li spheroidizing thiab tiv thaiv - kho corrosion.
03. Daim Ntawv Thov Cheeb Tsam
Hais txog kev siv thaj chaw, ductile hlau kav yog siv dav hauv cov kav dej hauv nroog / cov kav dej hauv nroog, ntev -kev hloov dej ntawm cov chaw cia khoom thiab cov nroj tsuag dej, rov qab cov dej sib txuas hauv cov dej phwj tuaj thiab cov chaw tsim hluav taws xob, cua sov tes hauj lwm, roj thiab cov kav dej, thiab lwm yam kev lag luam vim lawv cov khoom zoo heev, corrosion resistance, muaj zog adaptability rau sudden zog sib koom tes, thiab yooj yim. Ordinary cam khwb cia hlau kav yog tsuas yog siv nyob rau hauv cov dej thiab cov kav dej, thiab lawv daim ntawv thov muaj kuj txwv.
