Kev tsim khoom sib txawv ntawm tungsten Carbide thiab HSS

Dab tsi yog Tungsten Carbide

Tungsten carbide yog cov khoom siv sib xyaw tungsten thiab carbon. Tungsten tau tshawb pom li wolfram los ntawm Peter Woulf. Hauv Swedish, tungsten carbide txhais tau tias "hnyav pob zeb". Nws muaj hardness heev, uas tsuas yog tsawg dua rau pob zeb diamond. Vim nws qhov zoo, tungsten carbide yog nrov hauv kev lag luam niaj hnub.

HSS yog dab tsi

HSS yog high-speed steel, uas yog siv los ua cov khoom siv txiav. HSS yog tsim rau lub hwj chim saw hniav thiab laum khoom. Nws tuaj yeem thim qhov kub thiab txias yam tsis poob nws qhov hardness. Yog li HSS tuaj yeem txiav nrawm dua li cov pa roj carbon ntau, txawm tias nyob hauv qhov kub thiab txias. Muaj ob hom high-speed steels. Ib qho yog molybdenum high-speed steel, uas yog ua ke nrog molybdenum, tungsten thiab chromium hlau. Lwm qhov yog cobalt high-speed steel, uas cobalt yog ntxiv los ua kom nws kub tsis kam.

Kev tsim khoom sib txawv

Tungsten carbide

Kev tsim khoom ntawm tungsten carbide pib los ntawm kev sib xyaw tungsten carbide hmoov thiab cobalt hmoov nyob rau hauv ib qho kev faib ua feem. Tom qab ntawd cov hmoov sib tov yuav ntub milling thiab ziab. Cov txheej txheem tom ntej yog nias tungsten carbide hmoov rau hauv cov duab sib txawv. Muaj ntau txoj hauv kev los nias tungsten carbide hmoov. Feem ntau ib qho yog molding nias, uas tuaj yeem ua tiav tau los ntawm lub tshuab nias hydraulic. Tom qab ntawd cov tungsten carbide yuav tsum tau muab tso rau hauv HIP qhov cub kom sintered. Tom qab cov txheej txheem no, kev tsim cov tungsten carbide tiav lawm.

HSS

Cov txheej txheem kev kho cua sov ntawm HSS yog qhov nyuaj dua li tungsten carbide, uas yuav tsum tau quenched thiab tempered. Cov txheej txheem quenching, vim tsis zoo thermal conductivity, feem ntau muab faib ua ob theem. Ua ntej, preheat ntawm 800 ~ 850 ℃ kom tsis txhob muaj kev kub ntxhov loj, thiab tom qab ntawd sai sai rau lub quenching kub ntawm 1190 ~ 1290 ℃. Cov qhab nia sib txawv yuav tsum tau muab qhov txawv ntawm kev siv tiag tiag. Tom qab ntawd nws yog txias los ntawm roj txias, cua txias, los yog them txias.

Nws pom tseeb tias tungsten carbide thiab high-speed steel muaj ntau qhov sib txawv hauv kev tsim khoom, thiab lawv muaj cov khoom sib txawv. Thaum peb tab tom xaiv cov khoom siv, nws yog qhov zoo dua los xaiv qhov uas haum rau peb tus mob thiab daim ntawv thov.

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.
