Dab tsi yog Tungsten Carbide Cov Menyuam

Nrog rau txoj kev loj hlob sai ntawm kev lag luam steel, txhawm rau txhim kho cov khoom tsim tawm ntawm cov hlau thiab txhim kho kev siv tus nqi thiab kev tsim khoom ntawm cov dov zeb, txo lub sij hawm kaw ntawm cov dov zeb, siv cov tungsten carbide cov menyuam nrog lub neej ntev kev pab cuam yog ib txoj hauv kev tseem ceeb. Cov cemented carbide roller, tseem hu ua cemented carbide roller nplhaib, hais txog ib yob ua los ntawm tungsten carbide thiab cobalt los ntawm cov hmoov metallurgical txoj kev.

Lub tungsten carbide cov menyuam tuaj yeem muab faib ua ob hom kev sib xyaw thiab sib xyaw raws li cov qauv tsim. Integral tungsten carbide cov menyuam tau dav siv nyob rau hauv pre-precision dov thiab xov stands ntawm high-speed hlau dov mills. Composite cemented carbide cov menyuam yog ua los ntawm tungsten carbide thiab lwm yam ntaub ntawv. Cov sib xyaw carbide chais yog nrum ncaj qha mus rau hauv cov menyuam ncej, uas yog siv rau ib tug dov zeb nrog ib tug hnyav load.

Carbide yob muaj ib tug siab hardness thiab nws hardness nqi txawv me me nrog kub. Tus nqi hardness nyob rau hauv 700 ° C yog 4 zaug siab dua cov high-speed steel. Lub elastic modulus, compressive zog, khoov lub zog, thiab thermal conductivity kuj yog 1 lub sij hawm siab tshaj cov cuab yeej hlau. Txij li cov thermal conductivity ntawm cov cemented carbide yob yog siab, cov cua kub dissipation nyhuv yog qhov zoo, yog li qhov saum npoo ntawm yob yog nyob rau hauv kub kub rau ib lub sij hawm luv luv thiab yog li lub sij hawm kub-kub cov tshuaj tiv thaiv lub sij hawm ntawm teeb meem impurities nyob rau hauv cov dej txias thiab cov yob yog luv dua. Yog li ntawd, cov tungsten carbide rollers muaj kev tiv thaiv corrosion thiab txias thiab kub qaug zog dua li cov cuab yeej steel rollers.

Qhov kev ua tau zoo ntawm tungsten carbide rollers muaj feem xyuam rau cov ntsiab lus ntawm daim ntawv cog lus hlau theem thiab qhov loj ntawm tungsten carbide hais. Lub tungsten carbide yog li ntawm 70% mus rau 90% ntawm tag nrho cov muaj pes tsawg leeg thiab qhov nruab nrab particle loj yog μm ntawm 0.2 mus rau 14. Yog hais tias cov hlau daim ntawv cog lus cov ntsiab lus yog nce los yog nce particle loj ntawm tungsten carbide, lub hardness ntawm cov cemented carbide txo. , thiab lub toughness yog txhim kho. Lub zog dabtsi yog khoov ntawm tungsten carbide roller nplhaib tuaj yeem ncav cuag 2200 MPa. Qhov cuam tshuam toughness tuaj yeem ncav cuag (4 ~ 6) × 106 J / ㎡, thiab HRA yog 78 txog 90.

Lub tungsten carbide yob muaj qhov ruaj khov zoo thiab kev ua haujlwm siab nrog kev hnav zoo heev thiab cuam tshuam tsis kam. Carbide roller yog dav siv rau dov tus pas nrig, hlau pas nrig, threaded steel, thiab seamless steel yeeb nkab, uas ua rau kev ua haujlwm zoo ntawm cov dov zeb.

Yog tias koj txaus siab rau tungsten carbide rollers thiab xav tau cov ntaub ntawv 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.
