Raws li lub ntiaj teb nto moo hom ntawm tsawg sulfur calcined,graphitized carburizing tus neeg sawv cevthiab txo tus neeg sawv cev rau cov khoom siv tshuaj, peb siv zog los tsim tus nqi rau ntau tshaj 3000 steel mills loj, foundries thiab tshuaj nroj tsuag hauv 65 lub teb chaws thoob ntiaj teb.

Ua ntej, steel mills, nyob rau hauv cov txheej txheem smelting ntawm hlau thiab steel khoom, vim lub sij hawm smelting, tuav lub sij hawm, overheating lub sij hawm thiab lwm yam, lub melting poob ntawm carbon ntsiab lus nyob rau hauv cov kua hlau nce, uas ua rau cov pa roj carbon ntsiab lus nyob rau hauv cov kua hlau tsis tau. ncav cuag qhov xav tau theoretical tus nqi ntawm refining.Nyob rau hauv tus txheej txheem ntawm smelting, ib qho kev faib ua feem ntawm carburizer yog muab tso rau hauv lub ntsiab lub hom phiaj yog kom cov pa roj carbon ntsiab lus nyob rau hauv lub molten steel, thiaj li mus smelt lub zoo tagnrho hlau.

Qhov thib ob, kev lag luam casting, carburizing tus neeg sawv cev siv hauv casting, tuaj yeem ua kom cov khoom seem steel ntau, txo cov npua hlau, thiab tus neeg saib xyuas carburizing muaj lub hom phiaj lubricating, tuaj yeem txhim kho kev pab cuam lub neej ntawm casting, txhim kho cov gradual zoo.

Hauv kev lag luam chemical engineering, lub cev thiab tshuaj lom neeg cov khoom ntawm kev txo cov neeg ua haujlwm yuav tsum ua kom tiav.Cov pa roj carbon raws li tus neeg sawv cev txo qis koom nrog cov tshuaj tiv thaiv.Nyob rau hauv cov xwm txheej kub kub combustion, cov tshuaj lom neeg daim ntawv cog lus ntawm oxide yog tawg, thiab carbon raws li ib tug txo tus neeg sawv cev yog oxidized, thiab valence nce.

Plaub, qee cov khoom siv ntxiv kuj tseem muaj txiaj ntsig rau tus neeg sawv cev carburizing, xws li nres lub ncoo nrog cov khoom siv ntxiv, ua cov khoom sib txhuam.
