Ntiav Hlau Txheej txheem cej luam

Zas casum ua kom zoo txhim kho cov cuab yeej siv ntawm cov hlau cam khwb cia ntse thiab muaj zog, yog li kom tau txais lub zog siab dua cov hlau. Lub zas hlau yog hom siab lub zog pov cov hlau cov khoom tsim tawm hauv cov rog ua tiav, nws yog ua tiav cov rog, muaj zog, hnav tsis kam lees yuav ntawm qhov chaw siab. Cov hlau yas tau tsim sai sai rau hauv ib qho cam khwb cia hlau khoom siv thib ob tsuas yog rau hlau hlau thiab dav siv. Qhov thiaj li hu ua "Hlau es tsis txhob siv hlau" feem ntau yog hais txog cov hlau can.

Zas Cov Hlau Lij Choj

Npua hlau yog ib qho cov hlau-carbon alloy nrog cov ntsiab lus carbon ntau dua 2%, thiab muaj C, P thiab lwm cov khoom ntawm smast race. Raws li cov qauv sib txawv ntawm cov pa roj carbon hauv npua hlau, nws tuaj yeem muab faib ua hlau hlau, nrum npua hlau thiab zas hlau.

Ib tug hlau cam khwb cia uas cov graphite yog spherical ua ke. Kev txiav cov nyhuv ntawm cov kab mob me ntawm cov hlau sib dhos yog qhov me me ntawm cov hlau cam tuaj yeem ncav cuag 120kgf / mm2, thiab nws muaj cov khoom muaj zog. Ntxiv nrog rau cov hlau, cov tshuaj lom neeg muaj kuab lom feem ntau: Cov ntsiab lus Carbon), cov neeg mob phosphorus 3.6%, tag nrho cov ntsiab lus tsawg dua 1.5% thiab ib qho tsim nyog tshaj li ntawm lub ntiaj teb, magnesium thiab lwm tus nodulators.

Zas cov hlau castings tau siv nyob rau hauv yuav luag nyob rau yuav luag txhua qhov kev lag luam loj, ua rau muaj lub zog loj, ua rau muaj siab tawv, corrosion tawm tsam thiab seem ruaj khov. Txhawm rau kom tau raws li cov kev hloov pauv ntawm cov kev hloov no, cov hlau duc muaj nyob hauv ntau cov qib, muab cov khoom siv tshuab thiab cov khoom siv mechanical.

Feem ntau nodular cock castings, raws li tau teev los ntawm cov koom haum thoob ntiaj teb rau kev kawm qib 1501083, yog tsuas yog tsim nyob rau hauv ib lub xeev tsis yog-alloying. Pom tseeb, cov ntau no suav nrog kev ua kom muaj lub zog muaj txiaj ntsig nrog tensile lub zog ntau dua 800 tus tshiab / hli thiab elongation ntawm 2%. Ntawm tus huab yog cov qib siab nrog elongation ntau dua 17% thiab sib raug lub zog qis (* tsawg li 370 Newton / hli Daus). Lub zog thiab elongation tsis yog thawj tus tsim qauv xaiv, thiab lwm yam tseem ceeb muaj zog, muaj zog thiab qaug zog thiab cuam tshuam cov khoom. Tsis tas li ntawd, corrosion tsis kam thiab oxidation tiv taus nrog rau cov khoom siv hluav taws xob kuj tseem ceeb rau cov neeg tsim qauv. Txhawm rau kom tau raws li cov kev siv tshwj xeeb no, ib pawg ntawm Austenitic ductile hlau tau tsim, uas feem ntau hu ua Austenitic ductic hlau. Cov Austenic no nodules yog tsuas yog siv nrog zinc, chromium thiab manganese thiab muaj nyob hauv cov qauv thoob ntiaj teb.

Zas Hlau Raug Cov Nkuav

(1) cov cai kom nruj rau cov khoom siv tshuaj lom neeg, cov pa roj caricon cov ntsiab lus ntawm cov xim av hlau, thiab cov ntsiab lus ntawm mangolhese, phosphorus thiab leej faj hauv cov hlau nrum hlau yog txo

(2) qhov ntsuas kub ntawm cov hlau hlau yog siab dua li cov grey cam khwb cia hlau, uas tau them nyiaj rau kev sib tw thiab cov khoom tsis muaj kua thiab txias thaum inoculation

(3) Kev Kho Mob Tawm Tsam, uas yog, ntxiv spheridizing tus neeg sawv cev rau cov kua hlau

(4) Ua kom tshem tawm kev kho mob

(5) Cov kav hlau yog cov neeg pluag, qhov tsis zoo, yog li qhov kev xav tau nchuav tawm qhov loj, cov ntawv thov ntawm cov riser, cov tshuaj txias, kev siv cov khoom siv txias

(6) Kev Kho Cua Sov
