Yam khoom siv twg yog tungsten steel?

Lub hardness ntawm tungsten steel yog thib ob tsuas yog pob zeb diamond, tab sis nws tsis tuaj yeem siv los ua cov hniav rau kev siv tib yam.

Hais txog tungsten steel, kuv ntseeg tias ntau tus phooj ywg tsis tshua hnov. Tab sis thaum nws los txog rau nws lwm lub npe: cemented carbide, txhua leej txhua tus yuav tsum tau paub txog nws vim hais tias nws yog tsim nyog los daws nws nyob rau hauv mechanical manufacturing. Cemented carbide yog cov khoom siv hluavtaws super-nyuaj, thiab nws cov khoom tseem ceeb yog cov hmoov dub tungsten tom qab sintered carbonization.

Raws li qhov sib txawv xav tau ntawm cov khoom, nws muaj pes tsawg leeg yog siab li 85% mus rau 97%. Tus so ntawm cov ntsiab lus feem ntau yog cobalt, titanium, lwm yam hlau, thiab binders. Peb feem ntau hais tias cemented carbide yog tungsten hlau. Hais lus nruj me ntsis, tungsten steel belongs rau cemented carbide. Tungsten yog ib qho tshwj xeeb ntom hlau nrog lub siab melting point thiab zoo hluav taws xob conductivity. Yog li nws yog siv los ua ib qho hluav taws xob filament thiab electrode ntawm argon arc vuam. Tungsten steel yog qhov tshwj xeeb los ntawm nws qhov siab hardness thiab hnav tsis kam.

Txawm nyob rau ntawm qhov kub ntawm ntau txhiab degrees, tungsten steel muaj siab hardness. Lub hardness ntawm tungsten hlau yog thib ob tsuas yog pob zeb diamond. Paub tias yog cov hniav ntawm kev lag luam niaj hnub no, tungsten steel muaj ntau yam zoo heev, xws li kub tsis kam, corrosion kuj, thiab zoo stability. Yog li ntawd, nws yog dav siv nyob rau hauv kev tsim cov cuab yeej high-speed txiav, xws li kais drills, milling cutters, saw hniav, thiab high-temperature rocket engine nozzles.

Txij li Rockwell hardness ntawm tungsten hlau yog siab li 90HAR, nws muaj tsawg toughness thiab yog tshwj xeeb nkig. Cov khoom siv tungsten steel zoo li yuav tawg thaum poob rau hauv av, yog li tungsten steel tsis haum rau kev siv cov hniav txhua hnub. Cov txheej txheem ntau lawm ntawm tungsten steel yog hmoov metallurgy. Ua ntej, cov hmoov sib xyaw tungsten yog nias rau hauv pwm thiab tom qab ntawd rhuab mus rau qhov kub thiab txias hauv qhov cub sintering. Tom qab txias, qhov yuav tsum tau tungsten steel dawb paug yog tau. Tom qab txiav thiab sib tsoo, cov khoom tiav tuaj tawm. Nrog rau kev txhim kho cov ntaub ntawv tshiab thiab thev naus laus zis, ntau lub teb chaws tab tom tsim cov superalloys tshiab, thiab tungsten steel yog cov hlau zoo tshaj plaws hauv cov khoom siv niaj hnub thiab metallurgy, thiab tungsten steel kuj dhau los ua cov khoom tseem ceeb hauv cov alloys. Yog li ntawd, nws muaj peev xwm tsim muaj zog tshiab alloys los ntawm cov khoom tshwj xeeb ntawm tungsten steel.

Yog tias koj txaus siab rau abrasive blasting nozzles lossis xav tau cov ntaub ntawv thiab cov ntsiab lus ntxiv, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug lossis xa US MAIL hauv qab ntawm nplooj ntawv.
