Hmoov Metallurgy Iav

Cov lus piav qhia luv luv:

Qhov no muaj feem xyuam rau daim teb tshwj xeeb ntawm hmoov metallurgy, raws li qhov ntom, porosity, cov ntaub ntawv thiab cov txheej txheem kev kho kub ntawm hmoov hmoov hlau ncaj qha cuam tshuam rau lub zog thiab lub zog.High ntom hais txog cov ntsiab lus ntawm siab hardness, me pores, siab ntom ntom, zoo cov khoom siv, siab hardness.Heat txoj kev kho mob feem ntau suav nrog carburizing quenching, carbonitriding, siab ntau quenching, tsawg zaus quenching, roj quenching, etc.Stable thiab tsim nyog quenching cov txheej txheem ua kom lub hardness ntawm tshav kub kho ruaj khov.

Qhov tseem ceeb kom zoo ntawm cov hmoov metallurgy yog tias nws yog ua los ntawm cov ntaub ntawv hmoov sintered, yog li cov roj da dej txij li cov roj nplua nyeem tau zoo heev, cov hniav kom zoo thiab txhua qhov ntau thiab tsawg tuaj yeem tsim, feem ntau tsis yog ua lwm yam; Qhov tsis zoo yog qhov txheeb ze ntawm cov tsoos ua. iav, lub zog tsis txaus, tsis tuaj yeem hloov lub qhov loj loj, cov hniav yog feem ntau hauv 6 ~ 9 qib, qhov tseeb qhov tseeb yog feem ntau IT7 ~ 6 qib.

Hmoov metallurgy yog lub tshuab tsim tshiab, nrog nws qhov zoo, tshwj xeeb tshaj yog haum rau huab hwm coj ntau lawm. Tab sis nws tsis yog rau txhua qhov xwm txheej.Powder metallurgical kev ua tiav yuav tsum muaj cov khoom lag luam ntawm cov coj ua kom tuag, siv cov hmoov hlau los ntawm kev ua txhaum thiab cov txheej txheem coj ua kom ua rau cov ntu.Qhov lub zog sib txawv raws li cov khoom siv.

1. feem coob ntawm cov tshuaj refractory hlau thiab lawv cov khoom sib txuas, cov khoom tsis muaj tseeb, cov khoom ntxeem tau tuaj yeem tsuas yog tsim cov hmoov hlau metallurgy txoj kev.

2. vim hais tias cov hmoov hlau metallurgy txoj kev tuaj yeem raug nias rau qhov kawg loj ntawm kev ua kom tiav, tsis tas lossis xav tau tsawg dua rau kev siv tshuab tom qab, nws tuaj yeem txuag tau hlau ntau, txo cov nqi khoom.Qhov poob ntawm cov hlau hauv kev tsim cov khoom los ntawm cov hmoov hlau ua kom zoo. txoj kev yog tsuas yog 1-5%, thaum lub sij hawm poob ntawm cov hlau hauv kev tsim cov khoom lag luam los ntawm cov txheej txheem casting zoo tib yam yuav dhau 80%.

3. vim hais tias cov hmoov hlau ua rau cov txheej txheem cov khoom tsim tawm tsis yaj cov khoom, nws tsis ntshai ua kom tsis haum nrog lub impurities coj los ntawm crucible thiab deoxidizer, thiab sintering feem ntau nqa tawm hauv lub tshuab nqus tsev thiab txo qhov huab cua, tsis txhob ntshai ntawm oxidation , thiab yuav tsis muab cov pa phem rau cov khoom siv, nws yog ua tau los ua cov ntaub ntawv purity siab.

4. hmoov metallurgy txoj kev tuaj yeem ua kom qhov tseeb thiab qhov sib thooj ntawm cov khoom sib xyaw.

5. hmoov metallurgy tsim nyog rau kev tsim cov khoom zoo ib yam thiab ntau cov khoom lag luam, tshwj xeeb tshaj yog iav thiab lwm yam nqi ua haujlwm siab ntawm cov khoom, nrog hmoov metallurgy kev lag luam tuaj yeem txo ntau lawm ntau lawm.

Kev tswj xyuas cov hmoov nyuaj ntawm cov khoom siv hmoov hlau dav thaum kho cov cua sov:

Qhov ceev ntawm cov atomized hmoov (suav nrog carbon hlau thiab tooj liab-carbon alloy steel) yog siab dua 6.9, thiab cov quenching hardness tuaj yeem tswj tau ib puag ncig HRC30.

Feem ntau, qhov ceev ntawm cov hmoov ua ntej-hmoov hmoov (AB hmoov) ntau dua 6.95, thiab cov quenching hardness tuaj yeem tswj tau ib puag ncig HRC35.

High prealloyed hmoov nrog lub ntom ntau dua 6.95 thiab quenching hardness tswj ntawm HRC40.

Hmoov metallurgy cov khoom ua los ntawm cov ntaub ntawv saum toj no muaj qhov ntom ruaj khov thiab cov khoom, thiab lub zog tom qab kho cua sov ua tau raws li qhov yuav tsum tau ua, yog li lawv lub zog tensile thiab lub zog compressive yuav mus txog lub ncov zoo dua.

Ua cov cua sov kho hardness ntawm cov hmoov metallurgy ncav cuag 45 steel? Tau kawg koj tuaj yeem!

Txawm li cas los xij, vim hais tias qhov ntom ntawm PM cov khoom lag luam tsis siab li ntawm No. 45 steel, qhov siab tshaj plaws ntawm PM nias qhov feem ntau yog 7.2 g / cm, thaum lub ntom ntom ntawm No. 45 steel yog 7.9 g / cm.Forced carburizing ntawm cov hmoov metallurgy lossis kev ua siab kub ua kom zoo tshaj HRC45 yuav ua rau cov hmoov metallurgy cov khoom tawg vim cov quenching siab, uas ua rau lub zog ntawm cov hmoov metallurgy cov khoom.

Tom ntej no, peb yuav muab piv rau P / M txoj kev ua tus iav nrog viav vias hob hle sib dhos.

1. Cov khoom siv ntawm cov khoom siv siab, nce mus txog ntau dua 95%

2. Tsis muaj los yog tsuas yog txiav me ntsis xwb

3. Cov ntsuas qhov loj me qhov sib txawv ntawm qhov chaw, zoo stability thiab siab precision.

4. Lub zog sib piv: cov hmoov kev lag luam metallurgy tuam txhab tau ua kom zoo cov hmoov metallurgy pwm tsim, thiab lub zog tensile thiab compressive zog ntawm cov iav tsim yog ze rau ntawm cov hobbing iav.Piv txwv li, lub zog tsav ntawm lub tsheb gearbox nrog lub siab kis siv zog kuj yog hmoov metallurgy iav.Visible, powder metallurgy iav yog cov tswv yim thiab dav.

5. Hmoov nias molding siv moulding pwm, tuaj yeem tsim lwm yam tshuab hobbing tuaj yeem tsis tuaj yeem tsim cov duab sib dhos.

6. Vim tias nws tsim nyog rau huab hwm coj ntau lawm, cov khoom siv ntau lawm thiab tus nqi qis dua kev txiav.

7. Tsim nyog rau huab hwm coj ntau lawm, yog li tus nqi sib tw kiag li.
