Puas yog cov ntsiab lus ruaj khov ntawm graphitized carburizer cuam tshuam qhov zoo ntawm cov hlau molten ncaj qha?

Kev siv cov carburizer hauv casting tuaj yeem ua rau kom cov khoom seem hlau ntau ntxiv, txo cov npua hlau los yog tsis siv npua hlau. Txoj kev pub mis ntawm lub cub hluav taws xob melting yuav tsum muab lub carburizer tso rau hauv lub qhov cub nrog cov khoom seem thiab lwm yam khoom siv, thiab ntxiv cov tshuaj me me tuaj yeem ntxiv rau saum npoo ntawm cov hlau kub, tab sis nws yog ib qho tsim nyog kom tsis txhob muaj qhov kub ntau. hlau los tiv thaiv oxidation ntau dhau thiab cov nyhuv carburizing tsis pom tseeb thiab cov ntsiab lus carbon ntawm cov casting tsis txaus. Ntxiv nrog rau cov teeb meem no, qhov zoo ntawm graphitization carburizer kuj tseem cuam tshuam los ntawm lwm yam, thiab peb yuav ua tib zoo saib ntawm qhov tshwj xeeb.
1, taag carbon cov ntsiab lus: dav dav graphitized carburizing tus neeg sawv cev tsau cov ntsiab lus kom ncav cuag ntau tshaj 99%, tsau cov ntsiab lus ncaj qha cuam tshuam qhov zoo ntawm casting kub hlau, plays lub luag hauj lwm tseem ceeb nyob rau hauv lub shrinkage ntawm kub hlau;
2, sulfur ntsiab lus: sulfur yog ib qho teeb meem nyob rau hauv lub graphitization carburizer, qhov qis dua cov sulfur ntsiab lus ntawm cov khoom casting yog qhov zoo dua;
3, cov ntsiab lus nitrogen: cov ntsiab lus nitrogen muaj qhov cuam tshuam ncaj qha rau cov qauv metallographic thiab cov khoom siv ntawm cov khoom siv hlau, cov ntsiab lus nitrogen siab dhau lawm, yuav ua rau cov casting tsim nitrogen pores;
4, cov ntsiab lus tshauv: cov hmoov tshauv ntau dhau yuav ua rau cov ntsiab lus ntawm impurities hauv molten steel, uas cuam tshuam ncaj qha rau cov khoom zoo;
5, noo noo cov ntsiab lus: graphitized carburizer nyob rau hauv cov dej cov ntsiab lus siab dhau heev lawm yuav ua rau lub casting porosity;
6, volatile cov ntsiab lus: volatile cov ntsiab lus siab dhau heev lawm yuav ua rau kom cov roj cov ntsiab lus nyob rau hauv molten steel, nce lub porosity.
Hauv cov ntsiab lus, ntawm ntau qhov ntsuas graphitized carburizer, cov ntsuas uas cuam tshuam rau qhov zoo ntawm cov khoom yog cov ntsiab lus ruaj khov carbon, sulfur, nitrogen, tshauv, cov teeb meem tsis zoo thiab cov ntsiab lus dej. Ntau hom cam khwb cia hlau yuav tsum xaiv ntau hom carburizer, thiab lub carburizer nws tus kheej yuav tsum xaiv cov pa roj carbon monoxide ntshiab graphitized los txo cov impurities ntau dhau ntawm cov npua hlau kom txo tau tus nqi ntawm casting.
