Dab tsi yogTwist xyaum?

Ntswj laum yog ib lo lus dav dav rau ntau hom kev siv, xws li kav hlau, cov kav dej yas, ua kom tsev ntoo, ua kom zoo nkauj thiab ua haujlwm xyaum ua haujlwm. Tag nrho cov kev xyaum laum muaj cov xeeb ceem ntau: cov fleeter flutes uas muab cov kav lawv lub npe. Txawv tshav ntswj tau siv nyob ntawm cov khoom tawv tawv ntawm cov khoom siv.

Los Ntawm Cov Khoom Siv

Kev Kub Ceev Hlau (HSS)

Cov ntaub ntawv tuaj yeem faib ua peb hom: High-ceev steel, cobalt-muaj cov hlau ceev-ceev thiab carbide.

Txij li 1910, high-ceev steel tau siv los ua cov cuab yeej txiav rau ntau tshaj ib puas xyoo. Tam sim no nws yog cov khoom siv siv dav dav thiab cov khoom siv pheej yig tshaj plaws rau cov cuab yeej. Kev nyab loj-ceev cov hlau siv tau siv tau ntawm ob txhais tes xyaum entamore ruaj khov xws li lub tshuab drilling. Lwm qhov laj thawj yog vim li cas hi-ceev steel kav ntev yuav yog vim tias cov cuab yeej ceev steel txiav tuaj yeem yog regrounded dua. Vim nws tus nqi qis, nws tsis yog tsuas yog siv ua hlua khi, tab sis kuj tau siv dav hauv cov cuab yeej tig.

Kev Kub Ceev Hlau (HSS)
Cobalt-muaj siab-ceev hlau

Cobalt-muaj cov hlau ceev-ceev (hsse)

Cobalt-muaj siab-ceev steel muaj cov hardness zoo dua thiab tawv tawv tawv dua li cov hlau ceev. Qhov nce nyob rau hauv hardness kuj tseem txhim kho nws cov kev coj tsis kam, tab sis nyob rau tib lub sijhawm txi ntawm nws txoj kev nruj. Tib yam li cov hlau ceev: lawv tuaj yeem siv los ua kom muaj pes tsawg zaus los ntawm kev sib tsoo.

Carbide (carbide)

Cementcarbide yog cov khoom siv hlau-raws li cov khoom siv hlau. Ntawm lawv, tungsten carbide yog siv los ua cov matrix, thiab qee lwm cov ntaub ntawv yog siv los ua cov ntaub ntawv sib txuas los ntawm cov txheej txheem sib txawv. Piv nrog high-ceev steel nyob rau hauv cov nqe lus ntawm hardness, tawv tawv liab thiab hnav tsis kam, nws tau txhim kho zoo heev. Tab sis tus nqi ntawm cov cemented carbide txiav cov cuab yeej kuj tseem kim kim dua li cov hlau ceev. Cemented carbide muaj cov txiaj ntsig zoo dua li cov khoom siv dhau los ntawm cov khoom lag luam lub neej thiab kev ua kom ceev. Hauv kev sib tsoo dua ntawm cov cuab yeej, kev sib tsoo cov cuab yeej sib tsoo yog qhov yuav tsum tau ua.

Carbide (carbide)

Los ntawm txheej

Tsis sib haum

Tsis sib haum

Cov tsho tshaj tuaj yeem sib faib ua ob hom hauv qab no raws li qhov kev siv ntawm kev siv:

Cov cuab yeej tsis muaj peev xwm yog cov pheej yig tshaj thiab feem ntau yog siv los ua qee cov ntaub ntawv mos xws li txhuas hlau thiab cov roj carbon qis.

Oxide Oxide Txheej

Oxide cov txheej txheem tuaj yeem muab cov cuab yeej tsis tshua muaj txiaj ntsig, kuj zoo dua hauv oxidation thiab kub tiv taus lub neej los ntawm ntau dua 50%.

Oxide Oxide Txheej
Titanium Nitride Txheej

Titanium Nitride Txheej

Titanium nitride yog cov khoom siv txheej txheej ntau txheej, thiab nws tsis haum rau cov ntaub ntawv nrog cov hardness thiab siab ua haujlwm.

Titanium Carbon Terride Txheej

Titanium carbon teride yog tsim los ntawm titanium nitride, tau muaj ntau dua cov kub ua rau thiab hnav tsis kam, feem ntau ntshav lossis xiav. Siv nyob rau hauv Haas Rhiav rau tshuab ua haujlwm ua los ntawm cov hlau cam khwb cia.

Titanium Carbon Terride Txheej
Titanium Txhuas Nitride Txheej

Titanium Txhuas Nitride Txheej

Titanium aluminium nitride yog tiv taus ntau dua rau qhov kub tshaj txhua yam saum toj no, yog li nws tuaj yeem siv rau hauv ib puag ncig siab dua. Piv txwv li, ua superalloys. Nws tseem haum rau kev ua cov hlau thiab stainless hlau, tab sis vim tias nws muaj cov hlau txhuas, tshuaj lom neeg cov tshuaj yuav muaj kev ua tiav cov ntaub ntawv uas muaj aluminium.

Dab tsi yog HSS laum?
HSS laum yog cov hlau hnyiab yog qhov cim los ntawm lawv daim ntawv thov kev pab Universal. Tshwj xeeb tshaj yog nyob rau hauv me me thiab nruab nrab koob ntau lawm tov khoom thiab thaum twg muaj kev tsis ruaj khov, cov neeg siv tseem cia siab rau cov cuab yeej ceev (HSS / HSCO) DRILLING cov cuab yeej.

Qhov sib txawv hauv HSS Hneev
High-ceev steel tau muab faib ua cov qib sib txawv nyob ntawm lub hardness thiab tawv. Alloy suav xws li tungsten, molybdenum thiab cobalt muaj lub luag haujlwm rau cov khoom no. Ua kom muaj cov txheej txheem Alloy nce qhov kev kub siab, hnav tsis kam thiab ua tau zoo ntawm cov cuab yeej, nrog rau tus nqi yuav khoom. Qhov no yog vim li cas nws yog ib qho tseem ceeb uas yuav tau xav txog pes tsawg lub qhov yog ua kom muaj nyob rau hauv cov khoom uas xaiv cov khoom txiav. Rau qee qhov me me ntawm qhov, cov nqi tej kev txiav txiaj ntsig zoo tshaj plaws HSS yog pom zoo. Cov khoom txiav siab dua xws li HSCO, M42 lossis HSS-E-PM yuav tsum tau xaiv rau koob ntau lawm.
