Nias
Nws yog muab tso rau hauv ib tug ntsug hydraulic los yog mechanical xovxwm qhov twg nws yog deposited nyob rau hauv ib lub cuab tam steel los yog carbide tuag ib zaug qhov tsim nyog alloy ntawm hmoov tau tov. JIEHUANG tuaj yeem nias cov khoom nrog txog plaub theem sib txawv ntawm kev nthuav dav zoo. Nyob ntawm qhov loj thiab qhov xav tau ntawm qhov ceev, txoj kev no siv 15-600MPa siab los tsim "ntsuab" qhov chaw uas muaj tag nrho cov yam ntxwv geometric ntawm qhov kawg tsim. Txawm li cas los xij, tsis yog qhov tseeb qhov kawg qhov ntev lossis nws cov yam ntxwv ntawm lub tshuab tsis muaj nyob rau lub sijhawm no. Kev kho cua sov tom ntej, lossis "sintering," kauj ruam ua tiav cov yam ntxwv.
Hlau sintering (sintering txheej txheem hauv hmoov metallurgy)
Cov ntawv ntsuab tau muab tso rau hauv qhov cub sintering kom txog rau thaum lawv ncav cuag qhov tsim nyog kawg lub zog, qhov ntom ntom, thiab qhov ruaj khov. Nyob rau hauv tus txheej txheem ntawm sintering, kub hauv qab lub melting point ntawm lub ntsiab hmoov tivthaiv ntawm ib feem yog rhuab nyob rau hauv ib tug tiv thaiv ib puag ncig kom molecularly txuas cov hlau hmoov hais uas ua rau ib feem.
Qhov loj thiab lub zog ntawm cov ntsiab lus ntawm kev sib cuag ntawm cov khoom compressed loj hlob los txhim kho cov khoom siv cov yam ntxwv. Txhawm rau kom ua tau raws li qhov kawg ntawm cov khoom tsis sib xws, sintering yuav ntsws, nthuav, txhim kho conductivity, thiab / los yog ua rau ib feem tougher nyob ntawm tus txheej txheem tsim. Nyob rau hauv lub sintering rauv, lub Cheebtsam yog muab tso rau ib tug nruam conveyor thiab maj mam thauj mus los ntawm lub cub tawg lub chambers kom ua tiav peb lub luag hauj lwm tseem ceeb.
Txhawm rau tshem tawm cov roj uas tsis xav tau ntxiv rau cov hmoov thaum lub sij hawm compaction, cov pieces yog thawj zaug maj mam rhuab. Cov khoom tom ntej no mus rau thaj chaw kub kub ntawm lub qhov cub, qhov kawg qhov zoo ntawm cov khoom raug txiav txim siab ntawm qhov ntsuas kub ntawm 1450 ° txog 2400 °. Los ntawm ua tib zoo ntsuas cov huab cua hauv lub cub tawg no, qee cov pa roj tau ntxiv los txo cov oxides uas twb muaj lawm thiab nres ntxiv oxidation ntawm cov khoom thaum lub caij kub kub no. Txhawm rau ua kom tiav cov khoom lossis npaj lawv rau ib qho txheej txheem ntxiv, lawv thaum kawg mus los ntawm chav txias txias. Nyob ntawm cov khoom siv thiab qhov loj ntawm cov khoom, tag nrho lub voj voog yuav siv sij hawm 45 feeb mus rau 1.5 teev.
Tom qab ua tiav
Feem ntau, covsintering khoomtuaj yeem siv ncaj qha. Txawm li cas los xij, rau qee cov khoom siv hlau sinter uas yuav tsum tau muaj siab precision thiab siab hardness thiab hnav tsis kam, yuav tsum tau kho tom qab sintering. Tom qab ua tiav suav nrog precision nias, dov, extrusion, quenching, nto quenching, roj immersion, thiab infiltration.
