Qhov ceev ntawm tungsten carbide

Tungsten Carbide, uas yog lub npe hu ua cov hniav nyiaj hniav kub, yog cov khoom lag luam qis qis. Nws yog nto moo rau nws cov khoom zoo heev nrog rau siab hardness, siab zog, siab ceev, hnav tsis kam, thiab corrosion kuj, yog li ntawd, nws tuaj yeem ua rau ntau yam laum, cutters, pob zeb drilling cuab yeej, cov cuab yeej mining, hnav qhov chaw, lub tog raj kheej liner. , thiab lwm yam. Hauv kev lag luam, peb yuav siv ntau qhov kev ntsuas los ntsuas thiab xyuas kom meej tias cov khoom tungsten carbide yog cov khoom zoo. Hauv tsab xov xwm no, cov yam ntxwv ntawm lub cev, qhov ntom ntom, yuav tau tham txog.

Dab tsi yog qhov ntom ntom?

Qhov ntom ntom yog qhov tseem ceeb ntawm cov cuab yeej cuab yeej ntsuas los qhia qhov loj ntawm cemented carbide ib chav tsev ntim. Lub ntim peb tau hais ntawm no, suav nrog qhov ntim ntawm qhov pores hauv cov khoom. Raws li lub thoob ntiaj teb system ntawm units thiab cov kev cai lij choj ntsuas units ntawm Tuam Tshoj, qhov ceev yog sawv cev los ntawm lub cim ρ, thiab chav tsev ntawm qhov ceev yog kg / m3.

Qhov ceev ntawm tungsten carbide

Nyob rau hauv tib txoj kev tsim thiab tib yam tsis, qhov ceev ntawm cemented carbide yuav hloov nrog kev hloov ntawm cov tshuaj muaj pes tsawg leeg los yog kev hloov ntawm raw khoom piv.

Cov khoom tseem ceeb ntawm YG series cemented carbide yog tungsten carbide hmoov thiab cobalt hmoov. Nyob rau hauv tej yam kev mob, raws li cov ntsiab lus cobalt nce, lub alloy ceev txo, tab sis thaum tus nqi tseem ceeb mus txog, qhov ceev fluctuation ntau yog me me. Qhov ceev ntawm YG6 alloy yog 14.5-14.9g / cm3, qhov ceev ntawm YG15 alloy yog 13.9-14.2g / cm3, thiab qhov ceev ntawm YG20 alloy yog 13.4-13.7g / cm3.

Cov khoom tseem ceeb ntawm YT series cemented carbide yog tungsten carbide hmoov, titanium carbide hmoov, thiab cobalt hmoov. Nyob rau hauv tej yam kev mob, raws li cov ntsiab lus ntawm titanium carbide hmoov nce, qhov ceev ntawm cov alloy txo. YT5 alloy ceev 12.5-13.2g / cm3, YT14 alloy ceev 11.2-12.0g / cm3, YT15 alloy ceev 11.0-11.7g / cm3

Cov khoom tseem ceeb ntawm YW series cemented carbide yog tungsten carbide hmoov, titanium carbide hmoov, tantalum carbide hmoov, niobium carbide hmoov, thiab cobalt hmoov. Qhov ceev ntawm YW1 alloy yog 12.6-13.5g / cm3, qhov ceev ntawm YW2 alloy yog 12.4-13.5g / cm3, thiab qhov ceev ntawm YW3 alloy yog 12.4-13.3g / cm3.

Vim nws qhov siab ceev, cemented carbide tuaj yeem ua rau ntau yam khoom, xws li cov khoom sib tsoo, qhov hnyav rods siv nyob rau hauv drilling industries xws li roj, moos pendulums, ballasts rau sailing, sailing, thiab lwm yam Counterweights, aircraft counterweights, thiab lwm yam. , uas tuaj yeem ua kom muaj kev sib npaug ntawm cov khoom hauv lub xeev ua haujlwm lossis zoo li qub, lossis txuag kev ua haujlwm ntawm cov neeg ua haujlwm.

Cov yam ntxwv ntawm tungsten carbide ntom

Qhov ntom ntom muaj feem xyuam rau cov khoom muaj pes tsawg leeg, raw khoom piv, microstructure, txheej txheem ntau lawm, txheej txheem tsis, thiab lwm yam. Feem ntau hais lus, daim ntawv thov teb ntawm cemented carbides nrog ntau qhov sib txawv kuj txawv. Cov hauv qab no feem ntau qhia txog qhov cuam tshuam ntawm alloy density.

1. Cov khoom muaj pes tsawg leeg

Cemented carbide tuaj yeem tsim los ntawm ob lub hmoov, tungsten carbide hmoov (WC hmoov) thiab cobalt hmoov (Co hmoov), los yog peb hmoov: WC hmoov, TiC hmoov (titanium carbide hmoov) thiab Co hmoov, los yog txawm WC hmoov. Hmoov, TiC hmoov, TaC hmoov (tantalum carbide hmoov), NbC hmoov (niobium carbide hmoov), thiab Co hmoov. Vim muaj qhov sib txawv ntawm cov ntaub ntawv alloy, qhov ntom ntawm cov hlau sib txawv, tab sis cov theem zoo sib xws: qhov ceev ntawm YG6 alloy yog 14.5-14.9g / cm³, qhov ceev ntawm YT5 alloy yog 12.5-13.2g / cm³, thiab qhov ceev ntawm YW1 alloy yog 12.6-13.5g / cm³.

Feem ntau hais lus, qhov ceev ntawm tungsten-cobalt (YG) cemented carbide nce nrog qhov nce ntawm WC hmoov cov ntsiab lus. Piv txwv li, qhov ceev ntawm alloy nrog WC hmoov ntsiab lus ntawm 94% (YG6 alloy) yog 14.5-14.9g / cm³, thiab WC hmoov ntsiab lus Qhov ceev ntawm 85% alloy (YG15 alloy)yog 13.9-14.2g/cm³.

Qhov ceev ntawm tungsten-titanium-cobalt (YT) nyuaj alloys txo nrog qhov nce ntawm TiC hmoov cov ntsiab lus. Piv txwv li, qhov ceev ntawm alloys nrog TiC hmoov ntsiab lus ntawm 5% (YT5 alloy) yog 12.5-13.2g / cm³, thiab TiC hmoov ntsiab lus yog 15%. Qhov ceev ntawm cov hlau (YT15 alloy) yog 11.0-11.7g / cm³.

2. Microstructure

Porosity feem ntau yog tshwm sim los ntawm qhov pores thiab shrinkage thiab yog ib qho tseem ceeb qhia rau kev txiav txim qhov zoo ntawm cemented carbide. Cov laj thawj tseem ceeb ntawm kev tsim cov cemented carbide pores muaj xws li kub hnyiab, cov organic inclusions, hlau inclusions, tsis zoo nias zog, thiab uneven molding agents.

Vim muaj cov pores, qhov tseeb qhov ntom ntawm cov hlau yog tsawg dua li qhov theoretical ntom. Qhov loj dua los yog ntau qhov pores, qhov tsawg ntom ntawm cov hlau yog nyob ntawm qhov hnyav.

3. Cov txheej txheem ntau lawm

Cov txheej txheem ntau lawm suav nrog cov txheej txheem hmoov metallurgy thiab kev txhaj tshuaj molding tshuab. Cov teeb meem xws li carburizing, under-burning, fouling, bubbling, tev, thiab uncompacting thaum nias thiab sintering yuav ua rau ib tug txo nyob rau hauv qhov ceev ntawm cemented carbide.

4. Ib puag ncig ua haujlwm

Feem ntau hais lus, nrog kev hloov pauv hauv qhov kub thiab txias, qhov ntim lossis qhov ntom ntawm cov hlau kuj tseem yuav hloov pauv tau, tab sis qhov hloov pauv me me thiab tuaj yeem tsis quav ntsej.

Yog tias koj txaus siab rau cov khoom siv tungsten carbide thiab xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb.
