Yuav ua li cas kom ntseeg tau qhov loj ntawm tungsten carbide khoom

Tungsten carbide yog cov khoom siv nyuaj tshaj plaws thib ob hauv ntiaj teb, tsuas yog tom qab pob zeb diamond. Tungsten carbide nto moo rau nws cov khoom zoo, xws li siab hardness, hnav tsis kam, cuam tshuam tsis kam, thiab kav ntev, yog li lawv zoo los tsim rau hauv cov khoom sib txawv tungsten carbide.

Raws li peb txhua tus paub, thaum peb tab tom tsim cov khoom lag luam tungsten carbide, peb ib txwm siv cov hmoov metallurgy, uas suav nrog kev cog lus thiab sintering. Thiab raws li peb tau tham txog ua ntej, tungsten carbide cov khoom yuav poob qis tom qab sintering. Tias yog vim li cas cov yas ntws nce thaum sintering. Qhov tshwm sim no tshwm sim, txawm li cas los xij, nws yuav ua rau muaj teeb meem rau kev tsim khoom tungsten carbide. Qhov ntawd txhais tau tias yog tias peb xav tau cov khoom lag luam tungsten carbide nrog qhov ntev ntawm 16mm, peb tsis tuaj yeem ua pwm nrog qhov ntev ntawm 16mm thiab compact nws rau hauv qhov loj vim tias nws yuav me dua tom qab sintering. Yog li yuav ua li cas peb thiaj li paub meej qhov loj ntawm tungsten carbide khoom?

Qhov tseem ceeb tshaj plaws yog constriction coefficient.

Lub constriction coefficient yog ib qho ntawm lub cev muaj nuj nqis hauv engineering. Qee yam khoom siv feem ntau ua rau lub ntim ntim vim tias lawv cov kev hloov pauv, qhov kub thiab txias hloov pauv, cov qauv kev hloov pauv, thiab theem hloov pauv. Lub constriction coefficient yog hais txog qhov piv ntawm constriction tus nqi rau tus nqi ntawm constriction factor.

Muaj ntau yam yuav cuam tshuam rau constriction coefficient. Qhov zoo ntawm cov hmoov sib xyaw tungsten carbide hmoov thiab cobalt hmoov thiab cov txheej txheem compacting yuav cuam tshuam rau constriction coefficient. Lub constriction coefficient kuj tuaj yeem cuam tshuam los ntawm qee qhov kev xav tau ntawm cov khoom, xws li cov khoom sib xyaw ntawm cov hmoov sib xyaw, qhov ntom ntawm cov hmoov, hom thiab tus nqi ntawm kev tsim tus neeg sawv cev, thiab cov duab thiab qhov ntau thiab tsawg ntawm cov khoom tungsten carbide.

Thaum tsim cov khoom lag luam tungsten carbide, peb yuav ua cov pwm sib txawv rau compacting tungsten carbide hmoov. Nws zoo li thaum peb tab tom compacting cov khoom tungsten carbide tib qhov ntau thiab tsawg, peb tuaj yeem siv tib lub pwm. Tab sis qhov tseeb, peb ua tsis tau. Thaum peb tab tom tsim cov khoom lag luam tungsten carbide tib qhov loj me tab sis qib sib txawv, peb yuav tsum tsis txhob siv tib lub pwm vim tias cov khoom tungsten carbide nyob rau qib sib txawv yuav txawv ntawm qhov ntom ntom, uas yuav cuam tshuam rau cov coefficient ntawm constriction. Piv txwv li, qhov constriction coefficient ntawm qib YG8 feem ntau yog nyob nruab nrab ntawm 1.17 thiab 1.26.

Yog tias koj txaus siab rau cov khoom lag luam tungsten carbide thiab xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL hauv qab ntawm nplooj ntawv.
