Poob- pov tseg pov tseg (peev casting), nrog nws qhov zoo ntawm kev ua haujlwm siab thiab cov qauv tsim, tau dhau los ua ib qho ntawm cov txheej txheem tsim khoom rau siab -kawg inserts. Nws muaj cov khoom siv dav dav, tso cai rau kev sib txuam ntawm cov khoom siv hlau sib txawv nrog cov khoom sib txawv raws li kev ua haujlwm ntawm cov ntxig ntxig (xws li txiav txiav, hnyav - lub luag haujlwm crushing, kev ua haujlwm sab nraum zoov, thiab lwm yam), thaum kawg ua kom lub zog thiab kev ua haujlwm ntawm cov ntxig ntxig. Cov hauv qab no yog cov ntaub ntawv tsim nyog thiab kev lag luam daim ntawv thov cov yam ntxwv ntawm ploj - pov tseg casting inserts.
I. Alloy Tool Steel: Qhov Kev Xaiv Qhov Tseem Ceeb rau Nruab Nrab -rau-High-End Inserts
Alloy cov cuab yeej steel yog cov khoom siv feem ntau rau kev ploj - pov tseg casting inserts. Los ntawm kev ntxiv cov ntsiab lus alloying xws li chromium, molybdenum, thiab tungsten, nws sib npaug hardness thiab toughness, ua rau nws haum rau feem ntau - lub hom phiaj daim ntawv thov. Ntawm lawv, chromium-molybdenum alloy steel muaj zog hnav tsis kam thiab cuam tshuam, ua rau nws tsim nyog rau kev tsim cov khoom hnyav-cov haujlwm xws li cov cuab yeej txiav ntoo thiab cov cuab yeej mining; tungsten-molybdenum alloy steel tau zoo heev - kub stability thiab siv tau rau hlau txiav inserts, muaj peev xwm tiv taus qhov siab - kub hnav thaum txiav. Poob- khib nyiab pov tseg tuaj yeem tswj xyuas qhov tseeb ntawm cov ntaub ntawv no, txo kev ua haujlwm puas tsuaj los ntawm kev ua haujlwm tom ntej, thiab tshwj xeeb tshaj yog tsim rau kev tsim cov khoom siv nrog cov kab txiav nyuaj lossis nti grooves.
II. High-Speed Steel: Cov khoom siv tseem ceeb rau Precision Cutting Inserts
High - steel ceev (xws li W18Cr4V) muaj qhov tawv tawv heev, hnav tsis kam, thiab xim liab. Nws tsis tshua yooj yim rau ntug dulling thaum lub sij hawm siab - txiav ceev, ua nws cov khoom tseem ceeb rau precision txiav inserts. Nws yog dav siv nyob rau hauv machining, pwm manufacturing, thiab lwm yam teb. Poob-wax casting tso cai rau kev tsim cov txheej txheem nyuaj hauv siab- nrawm steel inserts thiab ua kom muaj kev tswj xyuas meej ntawm cov txheej txheem melting, txo cov porosity sab hauv, suav nrog, thiab lwm yam tsis xws luag, kom ntseeg tau tias qhov tseeb thiab qhov sib xws ntawm cov ntawv ntxig txiav. Rau cov txheej txheem precision txiav inserts xav tau ntau lawm, kev sib xyaw ua ke ntawm high{10}}ceev steel thiab poob{11}}wax casting sib npaug kev ua tau zoo thiab kev ua haujlwm ntau lawm.
III. Carbide thiab Composite Materials: Qhov Kev Xaiv Tshwj Xeeb rau High-End Wear-Resistant Applications
Carbide (xws li WC-Co series) muaj qhov nyuaj tshaj li ntawm cov cuab yeej hlau thiab tsis tshua muaj siab hnav, tab sis kuj tsis zoo toughness. Los ntawm kev sib xyaw ua ke thev naus laus zis ntawm kev poob- siv quav ciab casting, kev sib xyaw ua ke ntawm "carbide txiav ntug + alloy steel matrix" tuaj yeem ua tiav- txiav ntug kom ntseeg tau tias hnav tsis kam, thaum lub matrix muab txaus toughness, zoo kawg nkaus haum rau kev txiav cov hlau tawv, pob zeb, thiab lwm yam kev thov. Tsis tas li ntawd, qee qhov siab -kawg txiav cov cuab yeej siv cov hlau tsis muaj steel (xws li 3Cr13), ua haujlwm poob -wax casting kom ua tiav cov qauv corrosion, ua rau lawv haum rau cov av noo thiab ntau- ib puag ncig ua haujlwm nruab nrab thiab tiv thaiv lub cuab yeej lub neej los ntawm kev txo qis vim xeb.
Hauv cov ntsiab lus, kev xaiv cov khoom siv rau poob -cov cuab yeej siv quav ciab yuav tsum ua tib zoo ua raws li cov kev ua haujlwm. Los ntawm kev siv ntau yam ntawm cov cuab yeej alloy steels thiab precision txiav peev xwm ntawm siab - ceev steels mus rau siab - kawg hnav tsis kam ntawm cemented carbide composite cov ntaub ntawv, ib tug ua tiav cov ntaub ntawv compatibility system tau tsim. Kev sib raug zoo zoo ntawm kev ploj tuag- cov txheej txheem wax casting nrog ntau yam ntaub ntawv, nrog rau kev tswj xyuas meej ntawm kev tsim cov khoom raug thiab cov khoom sib xws, muab lub ntsiab lus lees paub rau kev ua haujlwm ntawm cov cuab yeej txiav hauv cov xwm txheej sib txawv, tsav kev txhim kho ntawm cov cuab yeej txiav khoom mus rau qhov tshwj xeeb thiab kev coj ua tau zoo.
