High Carbon Steel (High Carbon Steel) feem ntau hu ua cov cuab yeej hlau, Cov ntsiab lus carbon ntawm 0.60% txog 1.70%, quenching thiab tempering.Hammers thiab crowbars yog ua los ntawm 0.75% carbon steel;tej cuab yeej xws li xyaum xyaum, kais dej thiab reamers yog ua los ntawm 0.90% mus rau 1.00% carbon steel.
Qhov saum npoo ntawm galvanized steel hlau yog du, du, tsis muaj kab nrib pleb, pob qij txha, prickles, nti thiab xeb.Cov txheej galvanized yog ib yam, muaj zog adhesion, ruaj corrosion kuj, zoo heev toughness thiab elasticity.
Lub hardness thiab lub zog ntawm high carbon steel feem ntau yog nyob ntawm seb cov pa roj carbon ntau npaum li cas nyob rau hauv kev daws, thiab nce nrog cov nyiaj carbon nyob rau hauv kev daws.Thaum cov ntsiab lus carbon ntau tshaj 0.6%, lub hardness tsis nce, tab sis tus nqi ntawm cov carbide ntau ntxiv, cov hnav tsis kam ntawm steel nce me ntsis, thiab cov yas, toughness thiab elasticity txo.
Rau qhov kawg no, feem ntau raws li kev siv thiab lub zog ntawm cov hlau, toughness kom phim xaiv cov hlau sib txawv.Piv txwv li, ua rau lub caij nplooj ntoos hlav lossis caij nplooj ntoos hlav-hom nrog lub zog me me, xaiv 65 # siab carbon steel nrog cov ntsiab lus qis dua.General high carbon steel yuav siv tau hluav taws xob rauv, qhib hearth, oxygen converter ntau lawm.Cov kev xav tau zoo dua lossis tshwj xeeb zoo tuaj yeem siv hluav taws xob rauv smelting ntxiv rau lub tshuab nqus tsev lossis hluav taws xob, slag remelting.
Hauv smelting, tshuaj muaj pes tsawg leeg, tshwj xeeb tshaj yog cov ntsiab lus ntawm leej faj thiab phosphorus, yog nruj me ntsis tswj.Txhawm rau txo qis kev sib cais thiab txhim kho cov cuab yeej isotropic, ingot tuaj yeem raug kub kub diffusion annealing (tshwj xeeb tshaj yog cov cuab yeej steel).Thaum lub sij hawm ua hauj lwm kub, yuav tsum tsis txhob forging (dov) kub ntawm hypereutectoid hlau yuav tsum tau tsawg (kwv yees li 800 ° C).Tom qab forging thiab dov, nag lossis daus ntawm coarse network carbide yuav tsum raug zam.Tiv thaiv decarburization decarburization thaum kho cua sov lossis ua haujlwm kub (tshwj xeeb yog qhov tseem ceeb rau lub caij nplooj ntoos hlav steel).Thaum lub sijhawm ua haujlwm kub, yuav tsum muaj qhov sib npaug txaus kom ntseeg tau qhov zoo thiab kev pabcuam ntawm cov hlau.
