Cov khoom siv ntshiab vibrating yog cov khoom siv kho amorphous tsim los ntawm kev co los ntawm kev co yam tsis ntxiv dej los yog kua. Nyob rau hauv kev txiav txim ntawm kev co, cov khoom tuaj yeem tsim cov khoom siv tuab thiab hnav, nws tseem muaj zog los ntawm thermosetting binder lossis ceramic Sintering tus neeg sawv cev. Cov ntaub ntawv qhuav vibrating yog cov khoom siv refractate, hmoov, binder, sintering neeg saib xyuas thiab ntxiv. Cov yam ntxwv ntawm cov khoom siv qhuav vibrating: cov khoom no yog qhov yooj yim sau cov pcerration me me ntawm cov zog me me kom tau txais lub cev me me uas muaj lub zog sib sau. Thaum siv, ib txheej ntawm kev ua haujlwm saum npoo nrog qee lub zog yog tsim los ntawm cua sov. Qhov tsis ua haujlwm tsis yog ua haujlwm tseem muaj qee qhov tsis txaus ntseeg thawj cov qauv ntom ntom. Tus qauv no pab txo cov kev ntxhov siab tshwm sim los ntawm kev nthuav dav lossis kev cog lus; pab kom tabkaum qhov sib txawv thiab kev txuas ntxiv ntawm cov kab nrib pleb; Pab tiv thaiv qhov kev ntxeem ntawm cov hlau yaj, thiab yog qhov yooj yim los rhuav tshem thiab ntxuav lub cub tawg. Cov khoom siv no yog tsim rau ntawm qhov chaw los ntawm kev co qauv. Kev tsim kho yog yooj yim, lub sijhawm tsim kho yog luv luv, thiab tsis muaj kev saib xyuas thiab ci yuav tsum muaj. Cov txheej txheej ua haujlwm tuaj yeem ncaj qha thiab maj nrawm rau sinter thiab muab tso rau hauv kev siv.
Cov ntaub ntawv co qhuav tau muab faib ua cov khoom siv acidration (silica, mullite-carbon, magnesium oxide-carbon, magide-calcium Oxide-Carbon, thiab lwm yam).

Tsim Nyog Particle muab qhab nia yog qhov kev txiav txim siab rau kev txhim kho qhov ceev ntawm cov khoom co kom qhuav thiab txo qhov sib cav ntawm cov ntxhib. Ntawm lub hauv paus ntawm coarse, nruab nrab thiab zoo me ntsis gregle partic thiab nce tus nqi ntawm cov hmoov zoo tuaj yeem txo cov pa saws cais. Txawm li cas los xij, ntau cov hmoov nplej zoo tshaj plaws tsis pub tsawg dua li 10μm yuav ua rau muaj kev sib cav sib cais thiab nce siab porosity. Txhawm rau kom tau txais tus qauv tuab nrog kev sau ntom ntom ntom thiab tsawg dua qhov kev cais tawm, nws raug nquahu kom cov feem ntawm cov khoom nruab nrab ntawm nruab nrab. Lub particle muab siv rau cov ntaub ntawv co ntshav qhuav yog: coarse: nruab nrab: zoo. Ua kom muaj qhov ntom ntom ntom ntom ntom nti cov khoom siv cov tshuaj co qhuav tuaj yeem txhim kho lawv cov corrosion tsis kam thiab thermal conductivity.
Lub fluidity ntawm cov ntaub ntawv co kom qhuav thaum lub zog me me ua tiav, cov qauv kev sib tw thiab kev co. Hais yam tsis muaj cov npoo (du) yog yooj yim dua kom ntws dua li cov npoo nrog cov npoo nrog npoo.
Hom thiab cov nqi ntawm thermosetting binder thiab ceramic Sintering tus neeg sawv cev yog qhov tseem ceeb pib sintering lawv tsim. Tus neeg sawv cev uas raug xaiv yuav tsum pib sintering ntawm qhov ntsuas kub thiab muaj zog. Nws yuav tsum tsis txhob txo cov khoom siv refractory ntawm cov khoom siv, tsim cov roj thiab cov tshuaj tsis zoo, thiab yuav tsis yog ib puag ncig ib puag ncig. Cov sintered lub cev yuav tsum tsis muaj kev tawg loj, nthuav dav, thiab condaction. Thermosetting Phenolic Resins, silicates, sulfates, borates, borates, piv txwv li thermosetting binders thiab ceramic Sintering cov neeg sawv cev. Kev xaiv tsim nyog yuav tsum tau ua raws li kev siv sib txawv thiab kev siv ntau yam.
Cov ntaub ntawv qhuav txias yuav tsim kho rau ntawm qhov chaw kev co thiab kev co ncaj qha kom tau txais cov khaub ncaws hnav thiab ua rau muaj kev sib tw. Cov khoom siv ncaj qha yog txhawm rau co cov khoom siv refractory ncaj qha nrog cov txheej txheej, sau cov txheej txheej tshiab, thiab tom qab ntawd ua tiav nws nrog lub vibrator. Qhov no yog ua txheej los ntawm txheej kom txog thaum cov kev tsim kho kom tiav. Zam kev sib tsoo ntawm txheej txheej thaum kev tsim kho. Kev cai tsis ncaj ncees yog qhov kev cai tswj hwm los ntawm Vibrator tsau rau sab hauv lossis sab nraud pwm tau kis tau los ntawm tus qauv, yog li densifying nws.
Cov tshuab sau ntom ntom ntawm cov ntaub ntawv vibrating qhuav tom qab molding yog ze ze rau cov qib siab, lub zog tshee ntawm lub vibrator, qhov ntau zaus thiab cov lej ntawm cov vibrators. Prelouding tuaj yeem nce cov thawj zaug sau ntom ntom ntom. Ua kom muaj kev co ntau dua tuaj yeem ua rau txhaws kom ceev. Thaum lub zaus ntsuas zaus saum 50Hz, nce lub zog ua kom muaj zog tuaj yeem ua kom muaj zog ntxiv rau lub cev ua haujlwm. Thaum cov khoom siv tshee qhuav tsis preloaded, qhov kev co tsim los ntawm ob txoj kev sib tw ua ke tuaj yeem ua tiav cov nyhuv tuab.
Nyob rau hauv ib tug cored induction rauv, lub rauv taws cua sov siv neutral qhuav vibrating cov ntaub ntawv. Cov khoom siv ntawm cov khoom siv ua kom qhuav vibrating siv nyob rau hauv lub sensor tuaj yeem hloov raws li kev siv. Acidic lossis neutral qhuav vibrating cov ntaub ntawv feem ntau siv nyob rau hauv cov hlau tsis-ferrous hlau smelting. Alkaline lossis nruab nrab Qhuav Vibrating cov ntaub ntawv feem ntau siv nyob rau hauv cov cub tawg smeel smair. Vim tias cov yam ntxwv ntawm kev tsim kho yooj yim thiab ua kom qhuav cov ntaub ntawv yog siv nyob rau hauv kev lag luam metallurgical thiab tuaj yeem txuag 30% lub zog piv nrog refractory casterrator. Siv cov ntaub ntawv vibrating qhuav nyob hauv nruam casting camterishes tundishes tuaj yeem txo cov nqi khoom los ntawm 20% piv nrog siv cov tswv cuab insulation.
Lub tundish magnesium-calcium qhuav vibrating cov khoom yog qhuav-tsim, thiab kev tsim kho yog nrawm. Qhov saum npoo yog tiaj thiab du tom qab kev tsim kho, uas tuaj yeem txo cov pa phem ntawm cov khoom siv ua haujlwm tundish rau cov hlau Molten. Tsis muaj dej ntxiv nyob rau hauv cov txheej txheem kev tsim kho ntawm cov khoom lag luam no, uas tuaj yeem ua rau lub sijhawm tundish, yog li txo roj noj. Cov kev pabcuam lub neej ntawm cov khoom siv qhuav yog ntau dua 24 teev, thiab cov kev pabcuam lub neej ntawm cov khoom siv qhuav yog ntau dua 12 teev. Ib puag ncig tus phooj ywg magnesium qhuav vibrating yog tus cwj pwm los ntawm cov roj tawm tsam rau cov roj ntsha, tsis muaj cov roj ntsha ua rau lub sijhawm ci, uas tau txais txiaj ntsig zoo rau ib puag ncig. Thaum siv, cov hlau molten tsis nce roj carbon lossis hydrogen, thiab tuaj yeem ntxuav cov hlau Molten. Cov khoom siv no tau siv nyob rau hauv ntau cov hlau mills nrog cov txiaj ntsig zoo kawg li.
