Dab tsi yog qhov zoo ntawm Tungsten Carbide hauv Tooling?

Raws li peb txhua tus paub, cov khoom siv tungsten carbide hu ua "cov hniav ntawm kev lag luam". Nws muaj hardness heev thiab siab ceev, dav siv nyob rau hauv kev txiav, drilling, thiab hnav tiv thaiv.

Wikipedia piav qhia txog tungsten carbide raws li qhov no: "Tungsten carbide (cov tshuaj formula: WC) yog cov tshuaj lom neeg (tshwj xeeb, carbide) uas muaj qhov sib npaug ntawm tungsten thiab carbon atoms. Nyob rau hauv nws daim ntawv yooj yim tshaj plaws, tungsten carbide yog cov hmoov grey zoo, tab sis nws tuaj yeem raug nias thiab tsim rau hauv cov duab los ntawm sintering siv rau hauv kev lag luam machinery, txiav cov cuab yeej, abrasives, armor-piercing shells, thiab hniav nyiaj hniav kub. Tungsten carbide yog kwv yees li ob npaug ntawm cov hlau, nrog rau Young's modulus ntawm kwv yees li 530-700 GPa, thiab yog ob npaug ntawm qhov ntom ntawm cov hlau - ze li ntawm nruab nrab ntawm cov hlau lead thiab kub. Nws yog piv nrog corundum (α-Al2O3) nyob rau hauv hardness thiab yuav polished thiab ua tiav tsuas yog nrog abrasives ntawm superior hardness xws li cubic boron nitride thiab pob zeb diamond hmoov, log, thiab cov tebchaw. "

Cov khoom siv tungsten carbide muaj qhov ua tau zoo. Dab tsi yog qhov zoo thaum siv cov khoom siv tungsten carbide hauv cov cuab yeej siv?

1. Siab hardness. Lub hardness ntawm tungsten carbide txawv ntawm 83HRA txog 94HRA. Lub siab tawv ua rau tungsten carbide hnav mus txog 100 npaug ntev dua li cov hlau hauv cov xwm txheej xws li kev puas tsuaj, yaig, thiab galling. Kev hnav-tiv taus ntawm tungsten carbide zoo dua li cov khoom siv hnav-tiv taus hlau.

2. Thaum tshav kub kub thiab oxidation tsis kam. Txhawm rau tsim tungsten carbide, cov khoom siv carbide yuav raug sintered nyob rau hauv lub qhov cub ntawm qhov kub ntawm ib ncig ntawm 1400 centigrade. Tungsten-base carbides ua tau zoo txog li 1000 ° F hauv oxidizing cua thiab 1500 ° F hauv cov cua tsis muaj oxidizing.

3. Dimensional Stability. Tungsten carbide tsis muaj qhov hloov pauv thaum lub sijhawm cua sov thiab cua txias thiab khaws nws qhov kev ruaj ntseg tsis muaj hnub kawg. Tsis tas yuav tsum tau kho cua sov.

4. Nto tiav. Qhov kawg ntawm ib qho as-sintered yuav yog li 50 micro inches. Nto, cylindrical lossis sab hauv sib tsoo nrog lub pob zeb diamond log yuav tsim 18 micro ntiv tes lossis zoo dua thiab tuaj yeem tsim qis li 4 txog 8 micro ntiv tes. Pob zeb diamond lapping thiab honing tuaj yeem tsim 2 micro ntiv tes thiab nrog polishing tsawg li 1/2 micro nti.

Zhuzhou Better Tungsten Carbide Company yog tus kws tshaj lij tungsten carbide muab kev pabcuam. Tungsten carbide pwm thiab tungsten carbide tuag yog ib qho ntawm peb cov neeg muag khoom zoo tshaj plaws. ZZbetter tuaj yeem tsim tungsten carbide txias taub hau tuag, tungsten carbide kub forging tuag, tungsten carbide drawing tuag, thiab tungsten carbide ntsia thawv tuag. Cov tuag saum toj no tau siv dav hauv ntau qhov kev lag luam thiab hloov cov hlau los ua qhov kev xaiv sab saum toj rau kev siv cuab yeej. Nrog lub siab hardness, siab hnav tsis kam, siab dabtsi yog khoov lub zog, thiab ruaj khov kev ua tau zoo nyob rau hauv siab thiab qis kub, tam sim no daim ntawv thov ntawm tungsten carbide yog txawm ntau dua li ua ntej. Peb lub tuam txhab yuav mus rau muab cov kev daws teeb meem zoo carbide rau peb cov neeg siv khoom thiab cov neeg muaj peev xwm nrog kev cia siab tias peb cov carbide tuaj yeem pab lawv ua tiav lawv cov nqi!

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.
