Qinhuangdao Zhongwei Precision Machine Parts Co., Ltd., Xovxwm Moulding Division (PM) tshwj xeeb hauv kev tsim cov hmoov metallurgy cov khoom xws li high-precision, tsis tshua muaj suab nrov roj-impregnated bearings thiab high-performance mechanical structural parts. Txhaj Moulding Division (MIM) tshwj xeeb hauv kev tsim cov complex, high-strength, high-precision qhov chaw nrog nplua nuj kev paub thiab kev tiv thaiv ib puag ncig. Lub tuam txhab nyob hauv Qinhuangdao, qhov twg Qinshihuang nkag rau hauv hiav txwv, Hebei Xeev. Qhov chaw thaj chaw zoo dua thiab kev thauj mus los yooj yim. Cov khoom tseem ceeb yog tooj liab-raws li, hlau-raws li, hlau-tooj liab-raws li roj-impregnated bearings, zog, cams, stainless hlau qhov chaw thiab lwm yam mechanical qhov chaw thiab ntau yam tshwj xeeb-zoo li tus qauv. Siv dav hauv cov khoom siv hauv tsev, tsheb, maus taus, cov cuab yeej hluav taws xob, khoom siv hauv chaw ua haujlwm, textile machinery, khoom noj khoom haus, xauv, rooj tog, khoom ua si thiab lwm yam lag luam.

Cov txheej txheem ntau lawm ntawm hmoov metallurgy yog dab tsi? Hmoov metallurgy thev naus laus zis tau tsim sai heev, thiab nrog kev tshwm sim tas li ntawm cov txheej txheem tsim khoom tshiab thiab cov cuab yeej siv, nws tau dhau los ua ib feem tseem ceeb ntawm kev lag luam niaj hnub no. Cov txheej txheem ntawm cov hmoov metallurgy tuaj yeem muab faib ua tsib theem: hmoov ua → sib tov → sib sau → sintering → tom qab kho.

1. Milling:

Pulverization yog txheej txheem ntawm kev ua cov ntaub ntawv raw rau hauv hmoov. Cov txheej txheem pulverization muaj xws li oxide txo txoj kev, atomization txoj kev, electrolysis txoj kev, rotating electrode txoj kev, thiab mechanical crushing method.

2. Kev sib xyaw:

Kev sib xyaw yog cov txheej txheem ntawm kev sib xyaw ntau yam uas yuav tsum tau ua hmoov hauv ib qho kev faib ua feem thiab homogenizing lawv ua cov hmoov dawb paug. Txoj kev sib tov yog muab faib ua peb hom: hom qhuav, semi-qhuav thiab hom ntub. Thaum lub sij hawm cov hmoov sib tov ua ntej, vim qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov khoom sib txawv, kev sib cais yuav tshwm sim thaum lub sij hawm sib xyaw hmoov. Tianshi hmoov metallurgy binder tuaj yeem txhim kho kev sib cais. Vim qhov sib txawv particle loj thiab tsis sib npaug ntawm cov hmoov, cov porosity yuav yooj yim nce. , lub binder tuaj yeem ua rau cov khoom xa tawm kom tsim nyog, sau cov pores, thiab txhim kho lub zog compact.

3. Kev tsim:

Kev sib sau yog cov txheej txheem ntawm kev muab cov sib tov sib xyaw ua ke rau hauv qhov tuag thiab nias nws mus rau hauv ib lub parison nrog rau qee yam duab, qhov loj me thiab qhov ntom ntom. Feem ntau siv txoj hauv kev rau kev sib sau muaj xws li chav tsev kub xovxwm sib sau thiab cua sov xovxwm sib sau. Tianshi hmoov metallurgy cov roj nplua nyeem tuaj yeem ua kom nruj thiab ua kom nruj, tuaj yeem txo cov teeb meem sab hauv thiab sab nraud ntawm lub neej ntawm cov pwm, yog li ntawd cov seem muaj qhov zoo ntawm qhov chaw tiav.

4. Sintering:

Sintering yog tus txheej txheem ntawm diffusion, vuam thiab recrystallization ntawm parison hais los ntawm sintering, kom cov hmoov hais kom khov kho ua ke, lub pores raug txo, qhov ceev yog nce, thiab thaum kawg ib "crystal ua ke" yog tau, yog li cov txheej txheem. ntawm tau txais tej yam lub cev thiab txhua yam khoom yuav tsum tau.

5. Tom qab ua tiav: Cov khoom siv hmoov metallurgy tuaj yeem siv ncaj qha tom qab sintering; tab sis thaum qhov kev ua tau zoo ntawm cov khoom lag luam siab, kev ua haujlwm tom qab feem ntau xav tau. Feem ntau siv cov txheej txheem tom qab ua tiav yog raws li hauv qab no:

1) Shaping: Muab cov khoom sintered rau hauv cov pwm zoo ib yam li cov qauv tuag, thiab ua lwm yam kev nias rau ntawm cov xovxwm los txhim kho qhov tseeb qhov tseeb ntawm qhov chaw thiab txo qhov roughness ntawm qhov chaw, uas yog siv los tshem tawm cov txheej txheem sintering. . Lub me deformation tshwm sim los ntawm nws.

2) Roj immersion: tus txheej txheem ntawm muab cov khoom rau hauv cov roj kub ntawm 100 ~ 200 degree los yog ua rau cov roj nkag mus rau hauv lub pores ntawm cov hmoov qhov chaw nyob rau hauv lub nqus tsev vacuum. Cov khoom ntub hauv cov roj tuaj yeem txhim kho kev hnav tsis kam thiab tiv thaiv qhov chaw los ntawm xeb.

3) Kev kho chav dej: Cov khoom siv hlau raug kho hauv 500 ~ 600 degree dej vapor los ua ib qho nyuaj thiab ntom ntom oxide zaj duab xis ntawm sab hauv thiab sab nrauv ntawm qhov chaw, yog li txhim kho qhov hnav tsis kam ntawm cov khoom thiab tiv thaiv cov khoom los ntawm xeb. .

4) Vulcanization kev kho mob: muab cov khoom tso rau hauv lub molten sulfur tank ntawm 120 degree, coj lawv tawm tom qab ntau tshaj kaum feeb, thiab rov ua kom sov rau 720 degree nyob rau hauv kev tiv thaiv ntawm hydrogen kom lub pores ntawm qhov chaw ntawm sulfides. Kev kho Vulcanization tuaj yeem txhim kho qhov kev sib txhuam txo thiab kev ua haujlwm ntawm qhov chaw.
