Caij nplooj ntoos hlavsteel hlauyuav tsum muaj lub zog tensile siab, elastic txwv, endurance thiab qaug zog lub zog, thiab tsis kam mus cuam tshuam thiab oscillation.Lub hom phiaj ntawm lub zog thiab kev ua siab ntev, tshwj xeeb tshaj yog los tiv thaiv qhov tshwm sim ntawm kev hloov kho cov kab nrib pleb, yog tus yuam sij rau kev noj cov khoom siv caij nplooj ntoos hlav.Qhov zoo ntawm sab hauv thiab sab nrauv zoo ntawm cov hlua hlau ncaj qha cuam tshuam rau kev ua haujlwm ntawm cov hlau.
Caij nplooj ntoos hlavsteel hlaunrog cov pa roj carbon zoo carbon steel qauv lossis cov cuab yeej carbon steel hlau qws ntau lawm, raws li kev siv lub caij nplooj ntoos hlav nruj tswj nws cov tshuaj muaj pes tsawg leeg, roj cov ntsiab lus thiab cov khoom tsis yog xim hlau.Txhawm rau kom txo qis cov tsos mob thiab decarbonization txheej, lub billet ntawm kev siv pas nrig yuav tsum nres qhov kev sib tsoo, thiab yog tias tsim nyog, nres lub tev.
Yuav tsum tsis txhob normalizing lossis soxhlet ua cov hlau pas nrig, spheroidization annealing yog siv los ntawm cov lus qhia loj.Hauv nruab nrab, tshwj xeeb tshaj yog ua ntej cov txheej txheem kos duab pov tseg, thermal pov tseg ntawm soxhlet yog dav siv.Tiv thaiv decarbonization thaum lub sij hawm thermal pov tseg.Tom qab kub pov tseg, sulfuric acid los yog hydrochloric acid pickling yog siv los tshem tawm cov ntawv hlau.Txheej yuav siv tau rau dip txiv qaub, phosphating, kho borax los yog tooj liab plating.
Cov txheej txheem kev kos duab ntawm cov khoom pov tseg muaj kev cuam tshuam zoo rau kev ua haujlwm ntawm cov khoom.Kev xaiv dav dav txog li 90% ntawm qhov loj dua qhov txo qis ntawm qhov chaw (saib cheeb tsam txo tus nqi) thiab qhov me me hla qhov txo qis (kwv yees li 23%), kom ntseeg tau tias cov khoom muaj zog.Nyob rau lub zog siab lub caij nplooj ntoos hlav steel hlau, rub yuav tsum tau tswj txhua lub sij hawm qhov kub ntawm cov hlau hlau qhov hluav taws xob qis dua 150 ℃, los tiv thaiv cov hlau hlau vim kev laus laus thiab hloov qhov tawg, uas yog lub ntsiab drawback ntawm steel hlau khib nyiab. .
