Hauv kev lag luam kev lag luam,tungsten carbide hniavtau dhau los ua tus thawj coj hauv kev ua haujlwm txiav vim nws lub zog siab, siab hardness thiab zoo heev hnav tsis kam. Txawm li cas los xij, feem ntau hais lus, thaum muaj cov hniav tig ntawm kev kub ceev thaum lub sij hawm txiav cov txheej txheem thiab los rau hauv kev sib cuag nrog cov khoom hlau, qhov muag pom tshwm sim ntsiag to tshwm sim - sparks ya. Qhov tshwm sim no tsis yog tsuas yog txaus siab xwb, tab sis kuj ua rau cov lus nug txog seb tungsten carbide hniav puas tsim cov txim thaum txiav. Hauv tsab xov xwm no, peb yuav tshawb txog cov ncauj lus no hauv qhov tob thiab qhia tshwj xeeb yog vim li cas vim li cas tungsten carbide hniav tsis tsim cov nplaim taws thaum txiav hauv qee yam mob.
Tungsten carbide hniavRaws li ib yam ntawm cov cemented carbide, feem ntau yog tsim los ntawm tungsten, cobalt, carbon thiab lwm yam khoom, uas muab nws zoo heev lub cev thiab tshuaj. Hauv kev ua haujlwm txiav, tungsten carbide hniav tuaj yeem txiav ntau yam khoom siv hlau yooj yim nrog lawv cov npoo ntse thiab kev sib hloov ceev. Txawm li cas los xij, nyob rau hauv cov xwm txheej tsis tu ncua, thaum cov hniav tig ntawm kev kub ceev kom txiav hlau, cov khoom me me ntawm cov hlau yuav raug ignited vim qhov kub ntawm kev sib txhuam, tsim cov sparks.
Txawm li cas los xij, tsis yog tag nrho cov tungsten carbide hniav tsim sparks thaum txiav. Raws li qee qhov tshwj xeeb, xws li kev siv tshwj xeeb sib piv ntawm cov ntaub ntawv tungsten carbide lossis kev siv cov txheej txheem txiav, tungsten carbide hniav tuaj yeem txiav yam tsis muaj txim. Tom qab qhov tshwm sim no yog cov ntsiab lus ntawm lub cev thiab tshuaj lom neeg.
Ua ntej tshaj plaws, qhov tshwj xeeb piv ntawm cov khoom siv tungsten steel yog qhov tseem ceeb. Thaum tsim cov tungsten carbide hniav, microstructure thiab tshuaj muaj pes tsawg leeg ntawm cov hniav tuaj yeem hloov pauv los ntawm kev kho cov ntsiab lus thiab feem ntawm tungsten, cobalt, carbon thiab lwm yam. Cov kev hloov no ua rau cov hniav uas muaj qhov coefficient ntawm kev sib txhuam thiab ntau dua thermal conductivity thaum lub sij hawm txiav. Thaum cov hniav nyob rau hauv kev sib cuag nrog cov hlau, lub tshav kub generated los ntawm kev sib txhuam yuav sai absorbed los ntawm cov hniav thiab ua tawm, tsis txhob ignition ntawm me me hais nyob rau hauv cov hlau nto, yog li txo cov tiam ntawm sparks.
Qhov thib ob, kev xaiv ntawm cov txheej txheem txiav kuj tseem ceeb heev. Hauv cov txheej txheem txiav, kev sib txhuam thiab qhov kub thiab txias ntawm cov hniav thiab cov hlau tuaj yeem tswj tau los ntawm kev kho qhov tsis xws li txiav ceev, txiav qhov tob thiab txiav lub kaum ntse ntse. Thaum txiav ceev yog nruab nrab, qhov txiav qhov tob yog ntiav thiab lub kaum sab xis txiav yog qhov tsim nyog, qhov kev sib txhuam thiab qhov kub thiab txias tuaj yeem txo qis, txo qhov tsim ntawm lub txim. Tsis tas li ntawd, kev siv cov coolant kom txias thiab lubricate qhov chaw txiav kuj tuaj yeem txo qhov kub ntawm cov hlau nto thiab txo kev sib txhuam, ntxiv kom txo tau qhov tsim ntawm lub txim.
Ntxiv rau cov laj thawj saum toj no, qhov tsis muaj qhov tsis zoo thaum txiav nrog tungsten carbide hniav kuj tseem muaj feem xyuam nrog cov khoom siv hlau. Qee cov ntaub ntawv hlau muaj cov ntsiab lus melting tsawg thiab siab oxidation tsis kam, uas tsis yooj yim rau ignited hauv cov txheej txheem txiav. Thaum cov hlau no tuaj rau hauv kev sib cuag nrog tungsten carbide hniav, nws yog ib qho nyuaj rau tsim sparks txawm tias muaj qee qhov kev sib txhuam thiab qhov kub thiab txias.
Txawm li cas los xij, nws tsim nyog sau cia tias txawm hais tias tshwj xeeb ntawm cov khoom siv tungsten steel thiab cov txheej txheem txiav tshwj xeeb tuaj yeem txo cov cim ntawm cov nplaim taws rau qee qhov, lawv tsis tuaj yeem tshem tawm tag nrho cov sparks. Hauv kev siv cov tswv yim, nws tseem yuav tsum tau ua cov kev ntsuas kev nyab xeeb tsim nyog, xws li hnav tsom iav tiv thaiv, khaub ncaws tiv thaiv hluav taws thiab hnab looj tes, txhawm rau ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm.
Tsis tas li ntawd, rau cov xwm txheej uas yuav tsum tau ua haujlwm nyob rau hauv qhov chaw tawg thiab tawg, txiav cov cuab yeej thiab cov hniav nrog kev ua haujlwm tawg yuav tsum raug xaiv los txo qhov kev pheej hmoo ntawm hluav taws thiab tawg. Nyob rau tib lub sijhawm, kev tshuaj xyuas tsis tu ncua thiab kev saib xyuas cov cuab yeej txiav thiab cov hniav kom ntseeg tau tias lawv nyob rau hauv kev ua haujlwm zoo kuj yog ib qho kev ntsuas tseem ceeb los txo qhov tsim hluav taws xob.
Los xaus, sebtungsten carbide hniavyuav tsim sparks thaum txiav nyob ntawm ib tug ua ke ntawm yam. Los ntawm kev kho qhov sib piv ntawm tungsten steel cov ntaub ntawv, optimizing cov txheej txheem txiav thiab xaiv cov khoom hlau zoo thiab lwm yam kev ntsuas, lub txim hluav taws xob tuaj yeem txo qis rau qee yam. Txawm li cas los xij, nws tseem yuav tsum tau ua raws li kev tiv thaiv kev nyab xeeb tsim nyog thiab kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua hauv kev siv tswv yim kom muaj kev nyab xeeb thiab kev ua haujlwm ntawm kev txiav. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho tas mus li ntawm cov txheej txheem tsim khoom, nws ntseeg tias yav tom ntej yuav muaj cov thev naus laus zis tshiab thiab kev ntsuas los txo cov cim hluav taws xob thiab txhawb kev nyab xeeb thiab kev loj hlob ntawm kev lag luam kev lag luam. .
Tom qab ntawd, Peb yuav hloov kho cov ntaub ntawv txuas ntxiv, thiab koj tuaj yeem nrhiav cov ntaub ntawv ntxiv ntawm peb lub vev xaib (passiontool.com) blog.
