Ua ntej, cov khoom hais:

Caij nplooj ntoos hlav steel hlau hais txog cov hlau nyob hauv lub quenched thiab tempered xeev elasticity, thiab rau cov siv thiab ua rau lub caij nplooj ntoos hlav thiab elastic Cheebtsam ntawm hlau. Lub elasticity ntawm cov hlau nyob ntawm nws rab peev xwm resiliently deform, ie, nyob rau hauv qhov kev cai tswjhwm ntau yam, cov resilient deformation rog mus ib certain thauj khoom thiab tsis muaj deformation lawm tom qab lub load rho tawm. Caij nplooj ntoos hlav steel hlau yuav tsum muaj kwm tej kev kawm, xws li txhua yam khoom (tshwj xeeb tshaj yog cov elastic txwv, tsuas pub ua tau, tus yield piv), ntawv uas los tiv thaiv elastic txo (los yog los tiv thaiv elastic zog, los tiv thaiv so los yog khoom), qaug zog, kev kawm, hardenability, lub cev, hab kev zog (kuj kub, kub tsis ua hauj, oxidation kuj, kuj corrosion, etc.). Yuav kom tau raws li cov kev cai, caij nplooj ntoos hlav steel hlau muaj zoo metallurgical zoo (purity siab thiab uniformity), zoo deg zoo (nruj tswj deg los tsis xws luag thiab decarburization), leej zoo thiab loj. Kev kawm ntawv yuav tsum dhia hauv poob siab, kev co los yog siv mus ntev ntawm tus ntoo khaub lig-kev nyuaj siab, ces yuav tsum caij nplooj ntoos hlav ntxaij hlau ua siab zog tensile, elastic txhob qaug zog loj zog. Nyob rau hauv tus txheej txheem yuav tsum lub caij nplooj ntoos hlav steel hlau tau ib cov hardenability, decarburization tsis yoojyim, deg zoo thiab lub caij nplooj ntoos hlav zoo cov hlau uas cov lus qhia hauv WC nyob rau hauv lub chav 0.6%-0.9% zoo cov qua hlau. Alloy caij nplooj ntoos hlav steel hlau no mas silicon-manganese hlau, yog lawv cov ntsiab lus ib nyuag sab, mas los ua cov ntsiab lus silicon Wsi lug txhim khu kev kawm; ntxiv nrog rau qhov Ge, tungsten, vanadium alloy caij nplooj ntoos hlav steel hlau. Xyoo tsis ntev los no, tag nrho nrog suav cov chaw muab kev pab, thiab raws li cov cai tshiab yees rau tsim tsheb thiab tsheb laij teb, cov tshiab steel qib uas hais xws li boron, niobium thiab molybdenum ntxiv los Si-Mn hlau tau tsim cas sim haum pab txoj hauj lwm ntawm springs hab txhim khu kev springs. Kev kho cua sov txog lub caij nplooj ntoos hlav steel hlau yuav tsum tau ib ntau zog thiab qaug zog txwv, feem ntau cov quenching + tempering nyob rau hauv lub xeev siv, yuav kom tau ib tug ntau dua elastic txwv. Kev kho cua sov kev kawm tshuab hauv xam qhovkev zoo lub caij nplooj ntoos hlav muaj ib feem tseem ceeb heev. Vim li no, li cas ntxiv kom qaug zog rau txoj hauj lwm ntawm lub hlav, yuav tsum xav kawm, tshwj xeeb tshaj yog tshuaj lom neeg yog hloov deg kub kho, peening thiab li mus tua tau ib feem tseem ceeb rau lub caij nplooj ntoos hlav qaug zog lub neej. Los cov valve caij nplooj ntoos hlav deg zog pab ntxiv, ua rau kom lub siab compressive, txhim kho lub neej qaug zog, valve caij nplooj ntoos hlav taus, mus ntxiv rau nitriding, kub tsis carbonitriding ua kua lossis leej faj nitriding kho, thiab mam li peening txhaj tshuaj tag. Piv txwv, Japanand #39; s f4mm si-cr roj quenched steel hlau 450 ℃ × 4.5h qes-kub carbonitriding thiab 400 ℃ × 15min tempering kub sib piv, tus nkees txwv yuav muaj 240mpa. Nitrogen infiltration xwb tsis eliminates txoj kev phiv los ntawm decarburization, tab sis tas li ntawd tus residual compressive kev nyuaj siab, thaum uas kub ua tau rau lub caij nplooj ntoos hlav hauv valve los nitriding thiab cov cryogenic kua carbonitriding yog zoo tuaj 0.2% ntawm 150 ° C 0.5%), 250 ℃ deformation % 0.56, si lub caij nplooj ntoos hlav valve thermal stability no thiab los tiv thaiv so stability, tab sis cov nitriding thiab cov kua carbonitriding sij hawm yuav tsum muab nruj me ntsis tej tshuaj , txwv tsis pub nws yuav tsim tau lub network ntawm sulfides thiab network nitride, tiam sis yuav txo nws lub dag lub zog qaug zog.

Caij nplooj ntoos hlav steel hlau siv:

Caij nplooj ntoos hlav hlau mas siv hauv locomotives, tsheb, muas tsheb, tractors, aircraft thiab ntau kauj caij nplooj ntoos hlav caij nplooj ntoos hlav.

Caij nplooj ntoos hlav tshuaj kub taub los sis phaj thickness siab tshaj 10-15 hli loj hlav, tej ntsiab lus kub-kuav los tiag hlau twv hlau qws lossis steel phaj yog ua los ntawm tug kub.

Ua thiab cov kev kho thaum tshav kub kub: lub caij nplooj ntoos hlav steel hlau thawj ncu rhaub kom tus kub tshaj qhov quenching qhov kub ntawm 50-80 ℃ nyob rau hauv cov hauj lwm uas txaus siab kub-kuav los tiag, thiab ces quenched nyob rau hauv txoj kev tempering rau tempering, los kom zoo yooj thiab qaug zog lub zog ntawm tus tempering sorbite. Caij nplooj ntoos hlav steel hlau quenching cua sov siv dua cov pa los yog tsis muaj oxidation khoom xws li lub cua sov ntsev da dej, rauv tiv cua, kom tsis txhob oxidation decarburization.

Caij nplooj ntoos hlav steel hlau tom qab kho cua sov yuav tsum kuj raug tua peening, has tus nto, uas ua rau residual compressive kev nyuaj siab, txhawb lub zog qaug zog.

Kub-kuav los tiag caij nplooj ntoos hlav steel hlau uas siv txoj kev no: ca hlau hlais - andgt; Thaum tshav kub kub dabtsi yog khoov txoj kev ua thaum tshav kub kub quenching + tempering + txhaj koob tshuaj tivthaiv peening - andgt; ntim.

, Txias thawj caij nplooj ntoos hlav kho cua sov txoj kab uas hla ntawm lub caij nplooj ntoos hlav, khaub thuas-kuav los tiag steel hlau siv tsawg tshaj 8 hli no-kuav los tiag txoj kev. Txheej txheem raug khaub thuas sib twv steel hlau thiab kub tej, mas nyob hauv peb cov pawg nram qab no:

① taug txhuas da dej txias twv steel hlau qho thawj peb sib law liag hlau teeb duab, cov deformation 50%, ces yuav tsum taug raws cua kub rau Ac3 saum qhov kub ntawm lub austenitizing, tag nrho cov nyiaj ntawd yuav 450-550 ℃ txhuas da hauv cov tshuaj isothermal, lub cev rau hauv tej nqaij mos rau sorbite. Paib zog ntawm 1600Mpa, yob no ntau heev dua, annealing ntawm 200-300 ℃ kev nyuaj siab yuav.

② roj quenching thiab tempering cov ntxaij hlau teeb duab kom loj npaum cas, roj quenching thiab tempering. Lub dag lub zog ntawm tej hlau no ua tsis tau zoo rau cov hlau lead-kho steel hlau, tab sis yog yam ntawv thiab tus nqi tsawg kawg yog. Tom qab no tejzaum txoj kev kho uas muaj kev nyuaj siab-relieving ib yam.

③ annealed steel hlau yog nqus tau cov hlau los ntawd luaj li cas yuav tsum tau txhaj, thiab mam li annealing. Tom qab tus softening tus mob khaub thuas-kuav los tiag steel hlau taus, yuav muaj kev quenching tom qab tempering rau qhov kub thiab txias mus cov yuav tsum tau txhaj txhua yam khoom. Alloy hais nyob rau lub caij nplooj ntoos hlav hlau rau lub luag hauj lwm tseem ceeb yog yuav ua kom cov neeg kho tshuab khoom, txhim kho kev kawm ntawv thiab ua tej yam khoom tshwj xeeb (xws li kub, ua hauj corrosion) ua luaj rau.

Hlau lis dej num thiab cov hlau qib coj kev sib raug zoo

Nrog kev dav thiab kev txawj ntse, phooj ywg hlau yog nrog tus tsim, raug thiab ua li ntawm rau lub caij nplooj hlav hlau wire65mn 60si2mna 55crsi sae9254v 50crva ASTM-A230-99, ASTM-A401, EN10270-2, JIS G3561. Ua ib tug neeg chaw tsim tshuaj paus, peb tam sim no theem koj zoo ntau yam steel nyob ntawm tej hauv Suav teb uas tawm hauv siab zog, toughness zoo thiab zoo hnav ua hauj. Los peb txais tos koj txog customized.
