Lub tungsten carbide pas nrig, tseem hu ua cemented carbide puag ncig bar, yog cov khoom siv cylindrical ua los ntawm tungsten carbide thiab cov hlau nplaum, feem ntau cobalt. Qws yog cov semi- tiav daim ntawv rau ntau cov cuab yeej txiav: lawv yog av, fluted thiab coated los ua kawg mills, xyaum, reamers thiab zawj cov cuab yeej. Vim tias lawv muab cov hardness siab heev nrog zoo toughness, lawv kuj ua hauj lwm raws li coj qhov chaw nyob rau hauv precision tooling.
Kev sib xyaw thiab kev tsim khoom
Carbide rods yog tsim los ntawm hmoov metallurgy. tungsten carbide hmoov yog tov nrog cobalt hmoov thiab me me ntawm grain - loj hlob inhibitors, milled rau hauv ib homogeneous slurry, qhuav, nias rau hauv ntsuab rods, thiab sintered ntawm kub kom tag nrho ntom. Cov ntsiab lus cobalt feem ntau yog nruab nrab ntawm 6 thiab 12 feem pua ntawm qhov hnyav, thiab qhov sib npaug yog tungsten carbide. Tom qab sintering, rods yog centerless - hauv av mus rau qhov kawg txoj kab uas hla kam rau ua thiab ncaj.
Cov khoom tseem ceeb
| Khoom | Yam ntau yam |
|---|---|
| Hardness | HRA 88 to 93 |
| Cov ntsiab lus cobalt | 6 mus rau 12 feem pua |
| Qhov ntom | 14.3-15.0 g ib cubic centimeter |

Cov no yog cov khoom lag luam raug cai. Ntau dua cobalt nce toughness ntawm tus nqi ntawm hardness, thiab qis cobalt nce hardness thiab hnav tsis kam ntawm tus nqi ntawm toughness.
Cov Qib Siab thiab Lawv Daim Ntawv Thov
| Qib tsev neeg | Cov qauv nplej | Tej daim ntawv thov |
|---|---|---|
| Ultra-zoo lis | Sub -micron carbide nplej | PCB laum, micro end mills, siab -machining ceev |
| Cov nplej zoo | Fine carbide nplej | End mills thiab laum rau steel thiab stainless hlau |
| Nruab nrab nplej | Standard carbide nplej | General machining ntawm cam khwb cia hlau thiab non{0}}ferrous hlau |
| Coarse nplej | Coarse carbide nplej | Hnav qhov chaw, mining thiab percussive cov cuab yeej |
Daim ntawv thov hauv cov cuab yeej txiav thiab hnav cov khoom
Carbide rods yog cov khoom pib rau cov khoom siv carbide txiav. Tom qab kev sib tsoo, cov pas nrig dhau los ua qhov kawg mills rau milling, xyaum ua lub qhov, reamers rau xov qhov thiab xov mills rau threading. Tshaj li kev txiav, rods yog machined rau hauv hnav pins, xuas nrig ntaus, qhia tuav thiab valve Cheebtsam uas qhov seem stability nyob rau hauv abrasion yuav tsum tau.
Yuav Ua Li Cas Thaum Yuav Carbide Rods
Plaub qhov txwv txhais tau hais tias carbide pas nrig. Qib, qhia los ntawm cov nplej loj thiab cov ntsiab lus cobalt, teeb tsa lub hardness - toughness sib npaug. Txoj kab uas hla kam rau ua thiab ncaj txiav txiav txim siab npaum li cas kev sib tsoo nyiaj uas tus tsim cov cuab yeej xav tau. Qhov ntev thiab muaj qhov nruab nrab ntawm qhov chaw lossis cov tiaj tus cuam tshuam rau kev ua haujlwm thaum sib tsoo. Thaum kawg, daim ntawv pov thawj zoo yuav tsum hais qhov ceev, hardness, transverse rupture lub zog thiab cov ntsiab lus cobalt yog li tus neeg yuav khoom tuaj yeem txheeb xyuas qib.
FAQ
Q1: Dab tsi yog qhov txawv ntawm cov pas nrig carbide thiab carbide bar?
Hauv kev lag luam feem ntau siv ob lo lus hais txog tib yam khoom cylindrical. Qee cov catalogs siv bar rau cov kab loj dua thiab cov pas nrig rau cov khoom me me, tab sis cov khoom siv thiab kev tsim khoom zoo ib yam.
Q2: Carbide rods puas tuaj yeem welded lossis brazed?
Brazing yog ua tau thiab feem ntau thaum txuas cov lus qhia carbide rau steel shanks. Fusion vuam tsis raug, vim tias thermal poob siab ntawm vuam tuaj yeem tawg cov carbide.
Q3: Dab tsi yog cobalt binder rau?
Cobalt khi cov tawv tungsten carbide nplej ua ke thiab muab tus pas nrig nws toughness. Ua kom cov ntsiab lus cobalt txhim kho qhov cuam tshuam tsis zoo tab sis txo qis hardness thiab hnav tsis kam.
Q4: Qhov luaj li cas yog carbide rods muaj nyob rau hauv?
Txoj kab uas hla feem ntau yog li ntawm 1 hli mus rau 40 hli, nrog cov qauv ntev xws li 310 hli thiab 330 hli, thiab qhov ntau thiab tsawg tuaj yeem xaj. Qhov kev xaiv nyob ntawm lub cuab tam txoj kab uas hla yuav tsum tau hauv av.
Q5: Kuv yuav xaiv li cas ntawm cov qib zoo thiab ntxhib nplej?
Fine thiab ultra- cov qib nplej zoo nplua cov cuab yeej txiav rau cov hlau thiab cua sov- cov alloys resistant, qhov twg ntug sharpness thiab hnav tsis kam. Coarse grain grades suit impact-loaded wear parts, where the toughness is more important than a chais edge.
