Los ntawm kev xav ntawm cov khoom muaj pes tsawg leeg, cemented carbide rolls yog npaj los ntawm cov hmoov hlau metallurgy txheej txheem los ntawm cov txheej txheem hlau metallurgy los ntawm kev siv cov khoom siv hlau refractory (xws li tungsten carbide WC, titanium carbide TiC, thiab lwm yam) raws li cov matrix, thiab cov hlau hloov pauv (xws li. cobalt Co, npib tsib xee Ni, thiab lwm yam) raws li lub binder theem. Qhov kev sib xyaw tshwj xeeb ntawm cov ntaub ntawv no muab tungsten carbide rolls qib siab ntawm hardness, hnav tsis kam thiab thermal qaug zog tiv thaiv, ua rau lawv tuaj yeem tiv taus qhov hnyav hnav thiab tsim kua muag ntawm high-temperature, high-pressure thiab high-speed dov txheej txheem. Ceramic yob yog raws li cov khoom siv ceramic thiab ua tiav los ntawm cov txheej txheem tshwj xeeb. Cov khoom siv ceramic nws tus kheej tsis tshua muaj siab hardness thiab zoo heev corrosion kuj, uas ua rau cov ceramic yob ua tau zoo nyob rau hauv cov txheej txheem dov, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm high yuav tsum tau rau lub nto tiav thiab corrosion kuj ntawm yob.
Hais txog cov yam ntxwv ntawm kev ua tau zoo, tungsten carbide rolls paub txog lawv cov hnav tsis kam thiab thermal qaug zog tsis kam. Nws muaj cov hardness siab thiab zoo thermal stability, thiab tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev hauv qhov kub thiab txias thiab siab load dov ib puag ncig, uas zoo heev txhim kho kev ua haujlwm ntawm cov dov zeb. Tsis tas li ntawd, tungsten carbide rolls kuj muaj cov thermal conductivity zoo, uas tuaj yeem tshem tawm cov cua sov sai sai thaum lub sij hawm dov, txo qhov kub ntawm cov yob, thiab txo qhov kev puas tsuaj ntawm thermal stress rau yob. Ceramic rolls, ntawm qhov tod tes, yog cov yam ntxwv ntawm lawv cov hardness siab, corrosion kuj thiab kub stability. Cov khoom tshwj xeeb ntawm cov ntaub ntawv ceramic ua rau cov rolls ceramic tsis yooj yim rau eroded los ntawm cov tshuaj thaum lub sij hawm dov txheej txheem, thiab muaj peev xwm tswj tau qhov tiav thiab qhov tseeb ntawm yob nto rau lub sij hawm ntev. Nyob rau tib lub sijhawm, ceramic rolls tuaj yeem ua haujlwm ruaj khov nyob rau hauv qhov chaw kub thiab txias, thiab yuav tsis deform lossis soften vim qhov kub thiab txias.
Nyob rau hauv cov nqe lus ntawm daim ntawv thov, cemented carbide rolls yog dav siv nyob rau hauv dov zus tau tej cov hlau, non-ferrous hlau, alloy cov ntaub ntawv thiab lwm yam lag luam vim hais tias ntawm lawv zoo heev zog. Tshwj xeeb tshaj yog nyob rau hauv high-lub zog, high-load rolling ib puag ncig xws li high-speed hlau qws dov mills thiab tiav dov mills, cemented carbide rolls ua lub luag hauj lwm irreplaceable. Ceramic rolls yog dav siv nyob rau hauv kub thiab txias dov ntau lawm kab nyob rau hauv steel kev lag luam, ceramic ntau lawm, iav ua thiab electronics kev lag luam vim lawv siab hardness, corrosion kuj thiab kub stability.
