Cov pa roj carbon caij nplooj ntoos hlav steel hlau yuav tsum muaj lub zog tensile siab, elastic txwv, endurance thiab qaug zog, thiab cuam tshuam thiab kev co kuj.Txhawm rau kom ntseeg tau tias lub zog thiab kev ua siab ntev, tshwj xeeb tshaj yog kom tsis txhob hloov qhov tshwm sim ntawm cov kab nrib pleb, yog tus yuam sij rau kev tsim cov hlau xaim caij nplooj ntoos hlav.Qhov zoo ntawm sab hauv thiab qhov chaw zoo ntawm cov hlua hlau ncaj qha cuam tshuam rau kev ua haujlwm ntawm cov hlau.
Cov pa roj carbon caij nplooj ntoos hlav steel hlau yog ua los ntawm cov pa roj carbon zoo thiab cov khoom siv zoo carbon steel lossis cov cuab yeej carbon steel hlau, thiab nws cov tshuaj muaj pes tsawg leeg, cov ntsiab lus roj thiab cov khoom tsis yog hlau yuav tsum tau tswj nruj me ntsis raws li kev siv lub caij nplooj ntoos hlav.Yuav kom txo tau qhov tsis xws luag thiab decarbonization txheej, lub billet tsim hlau pas nrig yuav tsum tau muab tso rau ntawm qhov chaw thiab tev tawm thaum tsim nyog.
Cov hlau pas nrig yuav tsum tau normalized los yog soxhlet ua tiav, es tsis txhob spheroidal annealing rau tus qauv loj.Soxhlet txheej txheem yog siv dav hauv kev kho cua sov ntawm qhov chaw, tshwj xeeb tshaj yog cov khoom ua ntej kos duab.Tsis txhob decarbonization thaum kho cua sov.Tom qab kev kho cua sov, sulfuric acid los yog hydrochloric acid pickling yog siv los tshem tawm cov ntawv hlau.Cov txheej txheem (saib tus neeg nqa khoom du) tuaj yeem yog dip-lime, phosphating, kho borax lossis tooj liab plating.
Cov txheej txheem kev kos duab ntawm cov khoom kos duab txheej txheem muaj kev cuam tshuam zoo rau cov khoom ua haujlwm.Feem ntau, qhov loj tag nrho qhov txo qis ntawm thaj tsam li 90% (saib cheeb tsam txo tus nqi) thiab tus nqi me me hla qhov txo qis (kwv yees li 23%) yog xaiv los xyuas kom meej qhov ua tau zoo ntawm cov khoom.Nyob rau lub zog siab lub caij nplooj ntoos hlav steel hlau, kev kos duab yuav tsum tswj qhov kub ntawm txhua qhov chaw ntawm cov hlau xaim qis dua 150 ℃, kom tsis txhob muaj cov hlau hlau vim kev laus laus thiab tshwm sim hloov qhov tawg, uas yog tsim cov hlau hlau. khawb qhov tseem ceeb tsis zoo.
