Cawv ntawm tsib lub ntsiab tseem ceeb ntawm cov hlau canile ntawm cov khoom siv

Cov tshuaj lom neeg cov tshuaj lom neeg ntawm cov hlau feem ntau suav nrog tsib hom carbon, silicon, mangelonese, phosphorus. Rau qee qhov kev sib tw nrog cov cai tshwj xeeb ntawm cov koom haum thiab kev ua tau zoo, ib qho me me ntawm cov khoom siv alloy kuj tseem suav nrog. Tsis zoo li cov xim dub cam khwb cia hlau, zas hlau cast hlau, zas hlau muaj kuj tseem muaj cov nqi ntawm cov khoom seem nyob rau hauv kev txiav txim siab kom ntseeg tau cov duab hluav taws xob. Peb tsim cov ntau ntawmCastings rau Japanese thiab European Tsheb, xws liCaij Nplooj Hlav Bracket, Caij nplooj ntoos hlav shackle,Lub Caij Nplooj Hlav Hlav thiab Caij Nplooj Ntoos Hlav.

1, cov pa roj carbon thiab cov pa roj carbon thiab cov roj carbon thiab cov pa roj carbon monoxide stepacis: Carbon yog cov khoom siv hlau, cov pa roj av siab pab graphitization. Txawm li cas los xij, cov pa roj carbon ntau yuav ua rau cov ntsej muag yooj yim. Yog li ntawd, qhov kev txwv ntawm cov roj carbon sib npaug hauv cov hlau uas muaj zog hauv lub hauv paus yog raws ntawm lub hauv paus ntsiab lus ntawm tsis muaj graphite ntab.

2, Silicon xaiv lub hauv paus ntsiab lus: Silicon yog ib lub ntsiab haum nraaj. Hauv cov hlau hlau, silicon tsis tuaj yeem tsuas yog txo cov qhov ncauj ntawm lub qhov ncauj dawb thiab nce tus nqi ntawm kev ua kom zoo nkauj eutectic thiab txhim kho cov roundness ntawm graphite spheres.

3, Manganese xaiv cov hauv paus ntsiab lus: raws li cov neeg Sulphur cov ntsiab lus hauv cov hlau uas muaj needralize, tsis tas muaj hlau ntau heev

4, phosphorus xaiv cov ntsiab cai: phosphorus yog ib qho kev ua phem, nws yog tsawg solubility hauv cam khwb cia hlau. Feem ntau, qis dua cov ntsiab lus ntawm phosphorus hauv cov hlau cadile, qhov zoo dua.

5, Cov Neeg Sulfur xaiv lub hauv paus: leej faj yog ib qho kev tawm tsam zoo nkauj, muaj kev sib zog ntawm cov mageroidal, ua rau slag, ua rau slag, porosity thiab lwm yam kev sib cais.

6, spheroidal cov ntsiab lus xaiv lub hauv paus ntsiab lus: nyob rau hauv lub premeide kev tsim nyog, cov seem uas nyob ntawm magnesium thiab tsawg hauv ntiaj teb yuav tsum tsawg li sai tau. Magnesium thiab tsis tshua muaj lub ntiaj teb cov seem muaj ntau dhau, yuav cuam tshuam rau cov khoom siv dawb ntawm cov duab ua rau lawv kab sib cais ntawm cov ciaj ciam.
