Cov Cua Txias Mode Tom Qab Cov Khoom Uas Cov Khoom Uas Tuaj Ua

Qhov txias txias tom qab muab cov khoom ua khoom tsim

Kev Ua Cov Khoom Uas Siv Cov khoom siv yog tsim los ntawm sab nraud quab yuam ntawm cov cuab yeej tawm ntawm cov nroj tsuag ua, kom tau cov txujci machining nrog tej khoom, qhov loj thiab yam khoom siv. Tom qab ntawd peb yuav tsum tau txias cia tom qab ua cov Machined Products, yog li hnub no peb yuav ua kom paub ib co kev txias rau tsibxi yongxin nyoos ua Machined Productss koom xwm.

High carbon thiab high alloy steel khoom ua Cov khoom siv tom qab ua kom tiav, kom tiv thaiv qhov chaw tawg, ua kom tau txias tom qab cov cua txias, ua kom txias txias, txias los yog faus sanding qis txias, tom qab tshav kub kho.

Cov hlau tsis muaj cov txuj ci khoom siv yuav tsum tau forged thiab tam sim ntawd nkag rau hauv dej. Lub hom phiaj yog ua kom cov qoob loj loj sai npaum li sai tau thiab tsis loj hlob tuaj. Nyob rau tib lub sijhawm, tsis xav kom muaj ntau lub koom haum los yog qhov nruab nrab ntawm cov nag lossis daus, ces yuav tsum ua cov tshuaj.

Tag nrho lwm cov pa nruab nrab-tsawg qis hlau thiab nruab nrab-qe alloy steel ua Machined Cov khoom yuav tsum yog huab cua-txias tom qab forging. Lub hom phiaj yog ua kom nws lub cev txias, hnav thiab teeb, kom tiv thaiv kev loj hlob thiab tov, kom yooj yim los sau ntawv cim. Cov hlau ntoo Cov Khoom Uas Cov Khoom Uas Them Nqi Ua Ntej Ua Ntej Thaum Kub Ntxhov Cov Dej Kub Kub tsis txias tshaj 50 ℃, tiv thaiv cov pob dawb.

Cov iav ntawm cov khoom siv muaj ntau yam khoom siv, cov iav uas siv cov khoom siv rau ntau yam: 40 cr, 42 crmo, 20 crmnmo, 20 crmnti, 42 crmo, 40 cr forging iav hauv cov crane kev lag luam hauv feem ntau loj loj iav ua Machined Khoom, 20 crmnmo, 20 crmnti forging iav siv nyob rau hauv mechanical kis tau tus mob, me me unowned (reference). Lub zog yuav tsum ua kom zoo dua qub, ua kom tsis muaj zog nyob rau hauv 38 mus txog 42 HRC tuaj yeem ua tiav qhov kev ua tau zoo, 42 crmo toughness yog zoo tshaj 40 cr, vim tias yav dhau los ntawm hardenability zoo dua kev kho cua sov, kev sib cuag thiab nws cov khoom loj. Tsis tas li ntawd, lub zog ntawm tib lub zog yog ze heev. Lub zog tensile ntawm cov kev kawm siab ntawm 40Cr yog 60 ~ 75 kg / hli squared, thiab tawm lub zog yog 35 ~ 55 kg / hli squared. Lub zog tensile ntawm 42CrMo yog 110kg / hli squared, thiab yield lub zog yog 95kg / hli. Kev kawm ntawm 42CrMo yog obviously zoo dua li ntawm 40Cr.

Cov ntaub ntawv 40Cr tau muaj kev sib zog zoo thiab muaj peev xwm ua rau tawv nqaij muaj zog 28 ~ 60mm thaum lub dej tawm, thiab cov roj yuav tau muab tso rau hauv txoj kab uas muaj 15 ~ 40 hli. Tom qab kho, cov khoom siv tau zoo mechanical zog, thiab muaj zoo low-notch rhiab heev thiab tsawg feem kub ntxhov. 40Cr gear Processing Machined Khoom siv feem ntau yog kho nrog kev sib ntau sib tua los yog ua kom nitrate tom qab ua qhov zoo. Thaum twg qhov kev hnyav yog 174 ~ 229HBS, qhov kev ua tiav kev ua haujlwm zoo dua, kev txheeb xyuas qhov sib txig yog 60%, thiab cov ntsiab lus ntawm cov khoom ntawm Machined ntawm 40Cr khoom khaws cia ntawm li 0.40%, thiaj li xyuas kom meej tias cov hlau muaj zoo lub zog thiab muaj zog. Qhov sib ntxiv ntawm Cr element yog tsuas yog los txhim kho lub zog ntawm cov hlau. Thaum lub quenching yog rhuab, Cr element yog ua tau tag nrho hauv cov txheej txheem Machined khoom lub cev thiab pab kom cov hardenability ntawm cov hlau. Tom qab quenching, Cr ntsiab solid tshuaj ua kom lub teeb meem zoo dua qub thiab pab kom muaj kev ruaj ntseg zoo ntawm qhov matrix. Thaum lub sij hawm kub siab txias, qee cov Cr ntsiab yog diffused ntawm cov ntaub so ntswg mus rau lub cev ntim ntawm carburized carburising (Cr, Fe) 3C.

Cov ntsiab lus nyob hauv 42CrMo iav yog khaws cia li ntawm 0.42%, uas ua kom pom tias cov hlau muaj lub zog zoo thiab muaj zog. Qhov sib ntxiv ntawm Cr thiab Mo ntsiab yog tsuas yog los txhim kho qhov nyuaj ntawm cov hlau. Thaum quenching thiab cua sov, cov Cr thiab Mo ntsiab yog cov khib nyiab hauv cov txheej txheem Cov khoom siv los txhim kho qhov nyuaj ntawm cov hlau. Tom qab quenching, Cr, Mo keeb khoom muaj zog txhawb kev loj hlob matrix lub koom haum, thiab txhim kho stability rov rau hauv matrix. Thaum lub sij hawm kub siab txias, qee cov Cr thiab Mo ntsiab yog diffused ntawm cov ntaub so ntswg mus rau lub cev carburized carburizing lub cev (Cr, Mo, Fe) 3C. Sib ntxiv ntawm Mo caij tau tshem tawm kev chim siab. Ntxiv ib qho me me ntawm Ni ntsiab tau txhim kho qhov toughness ntawm cov hlau.
