Txias ua haujlwm tuag hlau feem ntau yog siv rau stamping, pam vov, ua xim hlau, hmoov nws yuav tsum muaj hardness, siab coj kev tawm tsam siab thiab muaj kev phom sij txaus. Feem ntau muab faib ua ob pawg: dav dav hom thiab hom tshwj xeeb. Piv txwv li, lub hom phiaj-lub hom phiaj txias ua haujlwm steel hauv Tebchaws Meskas feem ntau suav nrog plaub qib steel: 01, d2, thiab d3. Qhov kev sib piv ntawm cov qauv stand ntawm dav dav-lub hom phiaj txias Alloy Tuag Jis ua haujlwm tuag hlau uas tuaj yeem siv tau yog SK Series, suav nrog SK Series Carbon Tool Steel, 8 SKD Series Alloy Tool Steels, thiab 9 Skhmo Series High-Ceev Cov Hlau, rau tag nrho ntawm 24 Cov Qib Steel. Tuam Tshoj tus GB / T1299-2000 Alloy Cuab Yeej Cuab Yeej Steel Steel muaj suav nrog tag nrho 11 cov qauv hlau, ua kom tiav ib qho kev ua tiav. Nrog cov kev hloov pauv hauv kev ua cov thev naus laus zis, cov ntaub ntawv ua tiav thiab thov kom tuaj pwm, cov thawj teev tseem tsis tuaj yeem ua tau raws li qhov xav tau. Japanese steel mills thiab loj European tuam thiab tuag steel manufacturers tau tsim kev ua haujlwm tshwj xeeb ua haujlwm steel
Tsawg Alloy Cua Quenching Txias Ua Haujlwm Khaub Ncaws Hlau
Nrog kev txhim kho ntawm kev kho cua sov sov, tshwj xeeb tshaj yog cov kev siv tshuab hluav taws xob quenching, txhawm rau kev lag luam ntawm lub pwm, kom tsawg-deformation hlau tau tsim nyob hauv tsev thiab txawv teb chaws. Hom hlau no yuav tsum tau ua haujlwm zoo thiab kev kho cua sov nws muaj lub zog me me, lub zog zoo thiab muaj qee yam hnav tsis kam. Txawm hais tias tus qauv high-alloy txias ua haujlwm tuag hlau (xws li D2, A2) muaj cov ntsiab lus zoo, nws muaj cov ntsiab lus siab thiab yog kim. Yog li ntawd, qee qhov qis-alloy micro-deformation steels tau tsim nyob hauv tsev thiab txawv teb chaws. Hom hlau no feem ntau muaj almoy ntsiab lus CR thiab MN alloy cov ntsiab lus los txhim kho cov kev nyuaj. Tag nrho cov ntsiab lus ntawm alloy ntsiab yog feem ntau <5%. Nws yog qhov haum rau kev tsim cov khoom ntsuas nrog cov khoom lag luam me me. Cov pwm nyuaj. Hlau los ntawm Tebchaws Meskas, ACS3 ntawm cov hlau tshwj xeeb, ° C thiab Tempering ntawm 200 ° C, tuaj yeem tswj hwm qee qhov nyiaj Ntawm khaws cia Austenite thiab muaj lub zog zoo, kev ruaj khov thiab seem ruaj khov. Nws tuaj yeem siv los ua cov khoom sib tw txias uas yog nquag chipping thiab txha lov. Kev Pab Lub Neej Siab.
Nplaim Thiaj quenched pwm hlau
Txhawm rau kom luv luv lub cim pwm tsim, piv txwv txog cov txheej txheem kev kho cua sov, txuag lub zog thiab txo cov nqi tsim khoom ntawm cov pwm. Nyiv tau tsim qee qhov tshwj xeeb ua haujlwm khaub thuas khaub thuas sib ntaus hlau rau nplaim quenching. Cov neeg raug suav nrog Achi Steel's SX105V (SX4 (HMD4), HMD1, Hitachi Steel tuam txhab G05, thiab lwm yam. Hom hlau no tuaj yeem siv los ua kom sov hniav lossis lwm qhov chaw ntawm cov pwm siv phom lossis lwm cov cua sov tom qab cov cua txias thiab tom qab ntawd. Feem ntau, nws tuaj yeem siv ncaj qha tom qab quenching. Vim nws cov txheej txheem yooj yim, nws yog siv dav hauv Nyij Pooj. Tus Sawv Cev Hlau Hom ntawm hom hlau no yog 7cricnmov, uas muaj cov khoom muaj txiaj ntsig zoo. Thaum φ80MM hlau yog roj quenched, lub hardness ntawm ib qho deb ntawm 30mm los ntawm qhov chaw tuaj yeem ncav 60HRC. Qhov sib txawv hauv hardness ntawm qhov tseem ceeb thiab saum npoo yog 3hrc. Thaum nplaim taws Quenching, tom qab preheating ntawm 180 ~ 200 ° C thiab cua sov rau 9hrc thiab hardened txheej tshaj 1.5mm tuaj yeem tau txais.
Kev High Tougness, Kev Hnav Siab Ua Haujlwm Txias Ua Haujlwm Steel
Txhawm rau txhawm rau txhim kho kev ua haujlwm zoo ntawm cov khaub ncaws tuag Hom hlau no feem ntau muaj txog li 1% carbon thiab 8% cr. Nrog rau ntxiv ntawm MO, V, SI thiab lwm cov khoom siv, nws cov carbides yog qhov muaj zog, thiab nws cov tawv nqaij tawv yog qhov ntau dua li ntawm CR12 hom hlau, thaum nws hnav tsis kam yog zoo sib xws. Cov. Lawv lub hardness, flexural lub zog, qaug zog zog thiab pob txha qaug zog nyuaj yog qhov siab, thiab lawv cov kev tawm tsam siab dua li Crl2 hom pwm hlau. Lawv yog qhov tsim nyog rau cov qib nrawm nrawm thiab ntau hom chaw nres tsheb punches. Tus sawv cev hlau hom ntawm hom hlau no yog Nyij Pooj DC53 nrog cov ntsiab lus tsawg thiab CRU-hnav nrog cov ntsiab lus siab. DC53 yog quenched ntawm 1020-1040 ° C thiab lub hardness tuaj yeem ncav cuag 62-63hrc tom qab cua txias. Nws tuaj yeem npau taws rau ntawm tsawg kub (180 ~ 200 ℃) thiab kub npau taws (500 ~ siab dua li D2, thiab nws cov kev ua tau zoo dua D2; Tom qab cru-hnav forging thiab dov, nws yog annealed thiab austenitized ntawm 850-870 ℃. Tsawg dua 30 ℃ / teev, txias rau 650 ℃ thiab tso tawm, lub hardness tuaj yeem xaiv tau li 63hrc, tempered ntawm 480 ~ 570 ℃ Raws li Txhawm rau siv cov xwm txheej, nrog pom tseeb cov nyhuv tawv, hnav tsis kam thiab tawv zoo dua D2.
Cov Hlau Hlau (High-Ceev Hlau)
High-ceev steel tau siv dav hlau txawv teb chaws los tsim cov kev ua haujlwm zoo thiab kev ua haujlwm ntev ntev, xws li Nyij Puam Kev Kub Siab Pwm SKH51 (W6Mo5CR4V2). Txhawm rau yoog raws li cov yuav tsum tau ntawm pwm, cov tawv yog feem ntau txhim kho los ntawm kev txo cov ntsiab lus ntsuas kub, quenching hardness lossis txo cov ntsiab lus carbon nyob rau hauv high-ceev steel. Matrix hlau yog tsim los ntawm cov hlau ceev, thiab nws cov tshuaj lom neeg yog sib npaug rau cov matrix muaj sib xyaw ntawm cov hluav taws xob nrawm tom qab quenching. Yog li ntawd, tus naj npawb ntawm cov carbides tom qab quenching yog cov me me thiab tusyees txhim kho kev nruj ntawm cov hlau piv rau cov hlau ceev. Tebchaws Asmeskas thiab Nyij Pooj tshua muaj cov hlau pib nrog cov qib vascoma, hloovrasrix1 thiab mod2 thaum xyoo 1970. Tsis ntev los no, DRM1, DRM2, DRM2, DRM3, thiab lwm yam. Feem ntau siv rau kev ua haujlwm txias tuaj pwm uas yuav tsum muaj kev nruj dua thiab cov kev tawm tsam zoo dua qub. Tuam Tshoj tau kuj tau tsim qee cov hauv paus pib, xws li 65nb (65cr4w3mo2vnb), 65w8cr4vti, 65cr5mo3w2vsiti thiab lwm yam hlau. Hom hlau no muaj lub zog zoo thiab siv tau dav thiab siv lub log tuab, thiab lwm yam, thiab tuaj yeem siv raws li sov extrusion tuag.
Cov hmoov metallurgy pwm hlau
LEDB-hom High-alloy txias ua haujlwm Tuag Steel ua los ntawm cov txheej txheem ntawm cov txheej txheem, uas muaj kev faib tawm cov khoom siv tsis zoo, kev sib tsoo thiab isotropy ntawm cov hlau. Nyob rau hauv xyoo tsis ntev los no, cov tuam txhab steel tshwj xeeb uas tau tsim cov cuab yeej ntawm hmoov metallurgy high-alloy tuag steel, uas tau coj mus rau txoj kev loj hlob ntawm hom hlau no. Siv cov hmoov metallurgy cov txheej txheem, lub atomized steel hmoov txias kom sai thiab zoo dua txhim kho qhov nyuaj, kev sib tsoo thiab isotropy ntawm cov pwm khoom. Vim tias cov txheej txheem ntau lawm no, cov carbides yog qhov zoo thiab hnav khaub ncaws thiab cov ntsiab lus vanadium ntxiv, yog li kev txhim kho cov qauv tshiab ntawm cov hlau tshiab. Piv txwv li, Nyij Pooj Dex Series (DEX40, DEX60, FECHERHOLM's Fax Series Cov Hmoov Muam thiab Tuag Hlau Ciaj Loj Cov. Txoj kev sib sau ntawm cov hmoov metallurgy hlau xws li CPMLV, CPM3V, lawv cov coj nruj thiab tawv ua kom zoo dua piv rau cov txheej txheem zoo tib yam.
