Lub caij nplooj ntoos hlav hlau yuav tsum muaj lub zog tensile siab, elastic txwv, endurance thiab qaug zog lub zog, thiab yuav tiv taus kev poob siab thiab oscillation.Lub hom phiaj ntawm lub zog thiab kev ua siab ntev, tshwj xeeb tshaj yog kev tiv thaiv kev hloov pauv, yog qhov tseem ceeb rau kev siv lub caij nplooj ntoos hlav.steel hlau.Sab hauv thiab sab nrauv zoo ntawm cov hlau txuas ncaj qha cuam tshuam rau kev ua haujlwm ntawm cov hlau hlau.
Lub caij nplooj ntoos hlavsteel hlauyog ua los ntawm cov pa roj carbon zoo thiab cov khoom siv zoo carbon steel lossis cov cuab yeej carbon steel hlau qws, thiab nws cov tshuaj muaj pes tsawg leeg, cov ntsiab lus roj thiab cov khoom siv tsis yog hlau yuav tsum tau tswj nruj me ntsis raws li kev siv lub caij nplooj ntoos hlav.Txhawm rau kom txo qis qhov tsis zoo thiab decarbonization txheej, kev noj cov pas nrig billet kom tsis txhob ntog sib tsoo, yog tias tsim nyog, tab sis kuj yuav tsum tsis txhob tev tawm.
Hlau pas nrig kom tsis txhob normalizing los yog soxaustenitizing kev kho mob, loj specifications nrog spheroidizing annealing xwb.Nyob rau hauv nruab nrab, tshwj xeeb tshaj yog ua ntej cov khoom pov tseg cov txheej txheem ntawm thermal pov tseg thoob plaws hauv kev xaiv ntawm soxaustenitizing pov tseg.Decarbonization yuav tsum tau tiv thaiv thaum lub sij hawm thermal pov tseg.Sulfuric acid los yog hydrochloric acid pickling tau siv los tshem tawm cov ntawv oxide tom qab kho kub.Txheej (saib lubrication carrier) yuav dipped nyob rau hauv txiv qaub, phosphating, borax pov tseg los yog tooj liab plating.
Cov txheej txheem kev kos duab ntawm cov khoom pov tseg cov txheej txheem kos duab muaj kev cuam tshuam zoo rau cov khoom lag luam.Feem ntau, qhov loj tag nrho saum npoo txo tus nqi (saib cheeb tsam txo tus nqi) thiab qhov txo qis ntawm qhov me me (txog ≤23%) raug xaiv los xyuas kom meej cov khoom kam rau ua.Hais txog lub zog siab lub caij nplooj ntoos hlav steel hlau, qhov kub ntawm txhua qhov hla steel hlau yuav tsum tau tswj xyuas thaum kos duab hauv qab 150 ℃, tiv thaiv cov hlau xaim los ntawm kev hloov cov kab nrib pleb vim kev laus, uas yog qhov tsis zoo ntawm cov hlau xaim.
