Kev ua tau zoo ntawm cov pwm steel
Tuag steel yog hom hlau siv los ua pwm xws li txias punching tuag, kub forging tuag, tuag-casting tuag, thiab lwm yam. Pwm cov ntaub ntawv yog cov khoom siv thiab technical hauv paus ntawm kev tsim pwm kev lag luam. Ntawm lawv, pwm hlau yog cov khoom siv pwm. Nws ntau yam, specification thiab zoo ua si lub luag hauj lwm txiav txim siab nyob rau hauv kev ua tau zoo, kev pab cuam lub neej thiab manufacturing voj voog ntawm cov pwm. Nyob rau hauv xyoo tas los no, cov khoom tsim tawm, cov cuab yeej siv technology, cov cuab yeej siv, kev ua haujlwm zoo, thiab ntau yam ntawm cov pwm hlau hauv tsev thiab txawv teb chaws tau ua tiav txoj kev loj hlob sai. Txoj kev loj hlob ntawm cov pwm hlau kuj tau txhawb cov khoom lag luam kom ua tau zoo, tus kheej, thiab tus nqi siab ntxiv. txoj kev loj hlob. Cov pwm muaj ntau yam kev siv, thiab cov khoom siv los ua pwm yog qhov dav heev. Cov khoom siv pwm feem ntau yog cov pwm hlau.
Kev Ua Haujlwm Yuav Tsum Kho Kho Tshaj Tawm
1. Cov txheej txheem Annealing
Lub spheroidizing annealing kub ntau yog dav, lub annealing hardness yog tsawg thiab tus fluctuation ntau yam me me, thiab tus nqi spheroidizing yog siab.
2. Forgeability
Nws muaj tsawg kub forging deformation tsis kam, zoo plasticity, dav forging kub ntau, tsis tshua muaj siab ntawm forging cracking, txias cracking thiab nag lossis daus ntawm network carbides.
3. rhiab heev rau oxidation thiab decarburization
Thaum rhuab ntawm qhov kub, nws muaj peev xwm tiv thaiv oxidation zoo, qeeb decarburization ceev, insensitive rau cua sov nruab nrab, thiab me ntsis pitting nyiam.
4. Machineability
Cov nyiaj txiav yog loj, cov cuab yeej poob qis, thiab lub tshuab ua haujlwm roughness tsawg.
5. Hardenability
Tom qab quenching, ib tug sib sib zog nqus hardened txheej yuav tau, thiab nws yuav hardened nrog ib tug me ntsis quenching nruab nrab.
6. Grindability
Kev sib tsoo lub log yog qhov me me hauv kev poob, thiab qhov sib tsoo tsis muaj qhov kub hnyiab yog qhov loj. Nws tsis yog rhiab rau qhov zoo ntawm kev sib tsoo log thiab cua txias, thiab nws tsis yooj yim rau kev puas tsuaj thiab sib tsoo tawg.
7. Hardenability
Tom qab quenching, nws muaj uniform thiab siab hardness.
Yim, quenching deformation cracking nyiam
Lub ntim hloov ntawm cov pa quenching yog me me, cov duab yog warped, lub distortion yog me ntsis, thiab tus nyiam ntawm txawv txav deformation yog tsawg. Pa quenching muaj tsawg tawg rhiab heev thiab yog insensitive rau quenching kub thiab workpiece puab.
